In March 2020, the Chilean Ministry of Health declared a nationwide State of Emergency. As a precaution, our management has implemented several measures to help reduce the speed at which the coronavirus spreads, including measures to mitigate the spread in the workplace, significant reductions in employee travel and a mandatory quarantine for people who have arrived from high risk destinations, in consultation with governmental and international health organization guidelines, and will continue to implement measures consistent with evolving coronavirus situation. The Company reports on the following points in relation to the outbreak of the COVID-19 virus and its being declared to be a global pandemic by the WHO: (1) Regarding the financial and operational effects that this situation could mean for the Company, it is worth noting that the Company sells its products worldwide, with Asia, Europe and North America being its main markets. Border closures, decrease in commercial activity and difficulties and disruptions in the supply chains in the markets in which we sell have impacted our ability to fulfill our previous sales volume estimates, the impact on our sales volumes and average prices will depend on the duration of the virus in different markets, the efficiency of the measures implemented to contain the spread of the virus in each country and fiscal incentives that may be implemented in different jurisdictions to promote economic recovery. For now, our operations have not seen any material impacts related to the outbreak of COVID-19 virus. We have taken measures to mitigate the impacts of this health emergency on our employees and limit the impact it could have on our operations (described below in point 2). (2) Regarding the measures that management has adopted or intends to adopt to mitigate possible financial and/or operational effects, we inform that the Company has implemented a series of measures in its operations in Chile and abroad that seek to protect its workers and reduce the speed at which the virus spreads. The measures adopted by the Company are: (a) The flexibility of the working day, arrival and departure times, together with the incentive to work from home in those cases where this is possible. (b) Avoidance of crowds, seminars and large meetings in the Company´s offices and operating facilities. (c) Strengthening personal hygiene protocols (use of alcohol-based gel, masks, etc.) and sanitation in plants, cafeterias and offices. (d) Significant reduction in domestic and international travel, along with obligatory quarantine for people who have arrived from high risk destinations. (e) The costs associated with the measures implemented by the company correspond primarily to increased expenses in transportation, supplies, room and board, among others. (3) We hereby inform that we do not currently have any other information that management believes is relevant to provide. 1.7 C On April 28, 2021, the Company completed a US$1.1 billion capital stock increase. The capital stock increase was approved at an extraordinary shareholders’ meeting held by the Company on January 22, 2021. It included a mandatory 30-day pre-emptive rights offering, under Chilean law, to existing holders of the Company’s Series B common stock and a corresponding pre-emptive rights offering to existing holders of American Depositary Shares (ADSs). Existing shareholders received transferable share rights to subscribe for shares of Series B common stock at a subscription price of US$50 per share and the share rights were traded in Chile on the Santiago Stock Exchange and the Electronic Stock Exchange. Existing ADS holders received transferable ADS rights to subscribe for ADSs at a subscription price of US$50 per ADS and the ADS rights were traded in the U.S. on the New York Stock Exchange. The pre-emptive rights offerings ended on April 24, 2021 with respect to the share rights in Chile and on April 19, 2021 with respect to the ADS rights in the U.S. Of the 22,441,932 new Series B shares offered in the pre-emptive rights offerings, a total of 21,687,549 Series B shares (including shares in the form of ADSs), i.e. almost 97% of the Serie B shares offered, were subscribed in the preemptive rights offerings. The remaining 754,383 Series B shares that were not subscribed for in the pre-emptive rights offerings were offered and placed in auctions conducted through the Santiago Stock Exchange to investors in Chile and outside Chile (including in the United States) on April 28, 2021, at an average price of approximately US$54 per share. As of December 31, 2021, contributed capital is US$ 1.1 billion net of expenses for ThUS 24,503. 1.8 A On February 17, 2021, the Board of Directors approved the investment in the Mount Holland lithium project in Western Australia. SQM's share of the project investment is expected to be approximately US$700 million, between 2021 and 2025. The feasibility study confirms an expected initial production capacity of 50,000 metric tons of lithium hydroxide during the second half of 2024. See Note 8.5.

Disclosure of Basis of presentation for the consolidated financial statements [Abstract]
Disclosure of basis of preparation of financial statements [text block]	Note 2 B 2.1 A These consolidated financial statements cover the following periods: (a) Consolidated Statements of Financial Position as of December 31, 2021 and 2020. (b) Consolidated Statements of Income from January 1 to December 31, 2021, 2020 and 2019. (c) Consolidated Statements of Comprehensive Income from January 1 to December 31, 2021, 2020 and 2019. (d) Consolidated Statements of Changes in Equity for the years (e) Consolidated Statements of Cash Flows for the years 2.2 C The consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with IFRS and represent the full, explicit and unreserved adoption of IFRS, issued by the International Accounting Standards Board. These consolidated financial statements fairly present the Company’s financial position, as of December 31, 2021 and 2020, the comprehensive results of operations, changes in equity and cash flows occurring for the three years ended December 31, 2021, 2020 and 2019. IFRS establish certain alternatives for their application, those applied by the Company are detailed in this Note and Note 3. The accounting policies used in the preparation of these consolidated financial statements comply with each IFRS in force at their date of presentation. 2.3 B The consolidated financial statements have been prepared on the historical cost basis except for the following: (a) Inventories are recorded at the lower of cost and net realizable value. (b) Financial derivatives measured at fair value. (c) Certain financial investments measured at fair value with an offsetting entry in other comprehensive income. 2.4 A New accounting pronouncements (a) The following standards, interpretations and amendments are mandatory for the first time for annual periods beginning on January 1, 2021: Amendments and improvements Description Mandatory for annual periods Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16 “Reform to the referential interest rate (IBOR)- Phase 2” Published in August 2020. These amendments provide certain simplifications in relation to the reform to the referential interest rates, including the replacement of a reference rate by an alternative. 01-01-2021 Amendment to IFRS 16 “Lease Concessions” - Published in March 2021. This amendment extends by one year the period of application of the practical case of IFRS 16 Leases (contained in the amendment to that standard published in May 2020), with the purpose of assisting lessees in accounting for COVID-19 related rental concessions. The amendment is effective for annual periods beginning on or after April 1, 2021. However, early adoption is permitted even for financial statements not authorized for issue as of March 31, 2021. 01-01-2021 Management determined that the adoption of the aforementioned standards, amendments and interpretations did not significantly impact the company’s consolidated financial statements. (b) Standards, interpretations and amendments issued that had not become effective for financial statements beginning on January 1, 2021 and which the Company has not adopted early are as follows: Standards and Interpretations Description Mandatory for annual periods Amendment to IAS 1 “Presentation of financial statements” on classification of liabilities. These amendments clarify that the liabilities will be classified as current or non-current depending on the rights that exist at the close of the reporting period. The classification is not affected by the expectations of the entity or the events subsequent to the report date (for example, the receipt of a waiver or noncompliance with the pact). The amendment also clarifies what IAS 1 means when referring to “liquidation” of a liability. The amendment must be applied retroactively in accordance with IAS 8. 01-01-202 3 Reference to the Conceptual Framework - Amendments to IFRS 3. Minor modifications were made to IFRS 3 “Definition of a Business” to update references to the conceptual framework for financial reporting without changing the requirements of business combinations. 01-01-2022 Amendment to IAS 16 “Property, plant and equipment”. This prohibits companies from deducting from the cost of the property any revenue received from the sale of articles produced while the company is preparing the asset for its anticipated use. The company must recognize this sales revenue and associated costs in the profit or loss for the fiscal year. 01-01-2022 Amendment to IAS 37, “Provisions, contingent liabilities and contingent assets”. This clarifies for onerous contracts which inevitable costs a company must include to assess whether a contract will result in a loss. 01-01-2022 Annual improvements to IFRS standards, 2018-2020 cycle. The following improvements were finalized in May 2020: IFRS 9 Financial Instruments. This clarifies which fees must be included in the 10% test for the derecognition of financial liabilities. 01-01-2022 IFRS 16 Leases. Modification of illustrative example 13 to eliminate the illustration of lessor payments in relation to improvements to rental properties, to eliminate any confusion as to the treatment of lease incentives. 01-01-2022 Amendments to IAS 1: “Presentation of the Financial Statements” and IAS 8 “Accounting policies, changes in accounting estimates and errors”. The amendments are intended to improve disclosures of accounting policies and to help users of financial statements distinguish between changes in accounting estimates and changes in accounting policies. 01-01-2023 Amendment to IAS 12 - Deferred taxes related to assets and liabilities that arise from a single transaction. These amendments require companies to recognize deferred taxes on transactions that result in equal amounts in taxable and deductible temporary differences in the initial recognition. 01-01-2023 Amendment to IFRS 10 “Consolidated Financial Statements” and IAS 28 “Investments in Associates and Joint Ventures”, Published in September 2014. These amendments address an inconsistency between the requirements in IFRS 10 and those in IAS 28 in dealing with the sale or contribution of assets between an investor and its associate or joint venture. The main consequence of the amendments is that a full gain or loss is recognized when a transaction involves a business (whether it is housed in a subsidiary or not). A partial gain or loss is recognized when a transaction involves assets that do not constitute a business, even if these assets are housed in a subsidiary. undetermined Management believes that the adoption of the above standards, amendments and interpretations will not have a significant impact on the Company’s financial statements. 2.5 B (a) Subsidiaries The Company established control as the basis of consolidation of its financial statements. The Company controls a subsidiary when it is exposed, or has rights, to variable returns from its involvement with the subsidiary and has the ability to affect those returns through its power over the subsidiary. The consolidation of a subsidiary starts when the Group controls it and it is no longer included in the consolidation when this control is lost. Subsidiaries are consolidated through a line by line method, adding items that represent assets, liabilities, income and expenses with a similar content, and eliminating operations between companies within the SQM Group. Results for dependent companies acquired or disposed of during the period are included in the consolidated accounts from the date on which control is transferred to the SQM Group or until the date when this control ends, as relevant. To account for an acquisition of a business, the Company uses the acquisition method. Under this method, the acquisition cost is the fair value of assets delivered, equity securities issued, and incurred or assumed liabilities at the date of exchange. Assets, liabilities and contingencies identifiable assumed in a business combination are measured initially at fair value at the acquisition date. For each business combination, the Company will measure the non-controlling interest of the acquiree either at fair value or as proportional share of net identifiable assets of the acquire.

Foreign Herikerbergweg 238, 1101 CM Amsterdam Zuidoost Holland Dollar - 100.0000 100.0000 2.6 I Investments in joint arrangements are classified as joint operations or joint ventures. The classification depends on the contractual rights and obligations of each investor, rather than the legal structure of the joint arrangement. (a) Joint operations The Company recognizes its direct right to the assets, liabilities, income and expenses of the joint arrangement. (b) Joint ventures and investments in associates Interests in companies over which joint control is exercised (joint ventures) or where an entity has significant influence (associates) are recognized using the equity accounting method. Significant influence is presumed when the investor owns over 20% of the investee’s share capital. The investment is recognized using this method in the statement of financial position at cost plus changes subsequent to acquisition and includes the proportional share of the associate’s equity. For these purposes, the percentage interest in the associate is used. The associated acquired goodwill is included in the investee’s book value and is not amortized. The debit or credit to the income statement reflects the proportional share of the profit or loss of the associate. Unrealized gains from transactions with joint ventures or associates are eliminated in accordance with the Company's percentage interest in such entities. Any unrealized losses are also eliminated, unless that transaction provides evidence that the transferred asset is impaired. Changes in associate’s or joint ventures equity are recognized proportionally with a charge or credit to "Other Reserves" and are classified according to their origin. The reporting dates of the associate or joint ventures, the Company and related policies are similar for equivalent transactions and events in similar circumstances. In the event that significant influence is lost, or the investment is sold, or held for sale, the equity method is suspended, not recognizing the proportional share of the gain or loss. If the resulting value under the equity method is negative, the share of profit or loss is reflected as zero in the consolidated financial statements, unless there is a commitment by the Company to restore the capital position of the Company, in which case the related risk provision and expense are recorded. Dividends received by these companies are recorded by reducing the value of the investment and are shown in cash flows from operating activities, and the proportional share of the gain or loss recognized in accordance with the equity method is included in the consolidated income statement under "Share of Gains (Losses) of Associates and Joint Ventures Accounted for Using the Equity Method''.

Disclosure of changes in accounting policies, accounting estimates and errors [text block]	Note 3 S 3.1 C In the consolidated statement of financial position, balances are classified in consideration of their recovery (maturity) dates; i.e., those maturing within a period equal to or less than 12 months are classified as current counted from the closing date of the consolidated financial statements and those with maturity dates exceeding the aforementioned period are classified as non-current. The exception to the foregoing relates to deferred taxes, which are classified as non-current, regardless of the maturity they have. 3.2 F The Company’s consolidated financial statements are presented in United States dollars, without decimal places, which is the Company’s functional and presentation currency and is the currency of the main economic environment in which it operates. Consequently, the term foreign currency is defined as any currency other than the U.S. dollar. 3.3 A (a) SQM group entities: The revenue, expenses, assets and liabilities of all entities that have a functional currency other than the presentation currency are converted to the presentation currency as follows: - Assets and liabilities are converted at the closing exchange rate prevailing on the reporting date. - Revenues and expenses of each profit or loss account are converted at monthly average exchange rates. - All resulting foreign currency translation gains and losses are recognized as a separate component in translation reserves. In consolidation, foreign currency differences arising from the translation of a net investment in foreign entities are recorded in shareholder’s equity (“foreign currency translation reserve”). At the date of disposal, such foreign currency translation differences are recognized in the statement of income as part of the gain or loss from the sale. The main exchange rates and UF used to translate monetary assets and liabilities, expressed in foreign currency at the end and average of each period in respect to U.S. dollars, are as follows: Closing exchange rates Average exchange rates Currencies As of December 31, 2021 As of December 31, As of December 31, 2021 As of December 31, ThUS$ ThUS$ ThUS$ ThUS$ Brazilian real 5.57 5.18 5.66 5.14 New Peruvian sol 3.99 3.62 4.04 3.60 Japanese yen 115.18 103.30 113.87 103.81 Euro 0.88 0.81 0.88 0.82 Mexican peso 20.54 19.93 20.90 19.97 Australian dollar 1.38 1.30 1.40 1.33 Pound Sterling 0.74 0.74 0.75 0.74 South African rand 15.94 14.61 15.88 14.88 Chilean peso 844.69 710.95 849.46 731.92 Chinese yuan 6.38 6.51 6.37 6.53 Indian rupee 74.42 73.30 75.40 73.65 Thai Baht 33.32 29.94 33.55 30.08 Turkish lira 13.28 7.36 13.54 7.70 UF (*) 36.69 40.89 36.48 39.73 (*) US$ per UF (b) Transactions and balances The Company’s non-monetary transactions in currencies other than the functional currency (Dollar) are translated to the respective functional currencies of Group entities at the exchange rate on the date of the transaction. Monetary assets and liabilities denominated in foreign currencies at the reporting date are retranslated to the functional currency at the exchange rate at that date. All differences are recorded in the statement of income except for all monetary items that provide an effective hedge for a net investment in a foreign operation. These items are recognized in other comprehensive income until disposal of the investment, when they are recognized in the statement of income. Charges and credits attributable to foreign currency translation differences on those hedge monetary items are also recognized in other comprehensive income. Non-monetary assets and liabilities that are measured at historical cost in a foreign currency are retranslated to the functional currency at the historical exchange rate of the transaction. Non-monetary items that are measured based on fair value in a foreign currency are translated using the exchange rate at the date on which the fair value is determined. 3.4 C Cash equivalents correspond to highly liquid short-term investments that are easily convertible into known amounts of cash and subject to insignificant risk of changes in their value and mature in less than three months from the date of acquisition of the instrument. For the purposes of the statement of cash flows, cash and cash equivalents comprise cash and cash equivalents as defined above. The statement of cash flows present cash transactions performed during the period, determined using the direct method. 3.5 F Management determines the classification of its financial assets at fair value (either through other comprehensive income, or through profit or loss), and at amortized cost. The classification depends on the business model of the entity to manage the financial assets and the contractual terms of the cash flows. In the initial recognition, the Company measures its financial assets at fair value more or less, in the case of a financial asset that is not accounted for at fair value through profit or loss, the transaction costs that are directly attributable to the acquisition of the financial asset on the date when the Company commits to the purchase or sale of an asset. In the case of account receivables and other accounts receivables, the transaction price at the initial recognition is measured. After initial recognition, the Company measures its financial assets according to the Company's business model for managing its financial assets and the contractual terms of its cash flows: (a) Financial instruments measured at amortized cost. Financial assets that meet the following conditions are included in this category (i) the business model that supports it aims to maintain the financial assets to obtain the contractual cash flows and the contractual conditions of the financial asset give place, on specified dates, to cash flows that are only payments of the principal and interest on the outstanding principal amount. The Company’s financial assets that meet these conditions are: (ii) cash equivalents; (iii) related party receivables; (iv) trade debtors; (v) other receivables. (b) Financial instruments at fair value. A financial asset should be measured at fair value through profit or loss or fair value through other comprehensive income, depending on the following: (i) "Fair Value Through Other Comprehensive Income": Assets held to collect contractual cash flows and to be sold, where the asset cash flows are only capital and interest payments, are measured at fair value through other comprehensive income. Changes in book values are through other comprehensive income, except for the recognition of impairment losses, interest income and exchange gains and losses, which are recognized in the income statement. When a financial asset is derecognized, the cumulative gain or loss previously recognized in other comprehensive income is reclassified from equity to the income statement. Interest income from these financial assets is included in financial income using the effective interest method. (ii) "Fair Value Through Profit and Loss": Assets that do not meet the amortized cost or "Fair Value Through Other Comprehensive Income" criteria are valued at "Fair Value Through Profit and Loss". (c) Financial equity assets at fair value through other comprehensive income. Equity instruments that are not classified as held for trading and which the Group has irrevocably chosen to recognize in this category. Amounts presented in other comprehensive income will not be subsequently transferred to profit or loss. 3.6 F The Company evaluates expected credit losses associated with its debt instruments carried at amortized cost and fair value through other comprehensive income. The impairment method used depends on whether there has been a significant increase in credit risk. The Company applies simplified approach to measure expected credit losses using the lifetime expected loss on all trade receivables. Expected credit losses are measured by grouping receivables by their shared credit risk characteristics and days overdue. The Company has concluded that the expected loss rates for trade receivables are a reasonable approximation of the loss rates for contract assets. Expected loss rates are based on sales payment profiles and historical credit losses within this period. Historical loss rates are adjusted to reflect current expectations and information regarding macroeconomic factors that affect the ability of customers to meet their commitments. Impairment losses from receivables and contract assets are shown as net impairment losses in the line “Impairment of financial assets and reversal of impairment losses,” see Note 21.7. The subsequent recovery of previously canceled amounts are credited to the same line. 3.7 F Management determines the classification of its financial liabilities at fair value or at amortized cost. The classification depends on the business model of the entity to manage the financial liabilities and the contractual terms of the cash flows. At the initial recognition, the Company measures its financial liabilities by their fair value more or less, in the case of a financial liability that is not accounted for at fair value through profit or loss, the transaction costs that are directly attributable to the acquisition of the financial liability. After initial recognition, the Company measures its financial liabilities at amortized cost unless the Company, at the initial moment, irrevocably designates the financial liability as measured at fair value through profit or loss. Financial liabilities measured at amortized cost are commercial accounts payable and other accounts payable and other financial liabilities. Amortized cost is based using the effective interest rate method. Amortized cost is calculated by considering any premium or discount on the acquisition and includes transaction costs that are an integral part of the effective interest rate. Financial liabilities are recorded as not current when they mature in more than 12 months and as current when they mature in less than 12 months. 3.8 R When the Company changes its business model for managing financial assets, it will reclassify all its financial assets affected by the new business model. Financial liabilities cannot be reclassified. 3.9 F The Company derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred; and the control of the financial assets has not been retained. The Company derecognizes a financial liability when its contractual obligations or a part of these are discharged, paid to the creditor or legally extinguished from the principle responsibility contained in the liability. 3.10 D Derivatives are recognized initially at fair value as of the date on which the derivatives contract is signed and, they are subsequently assessed at fair value. The method for recognizing the resulting gain or loss depends on whether the derivative has been designated as an accounting hedge instrument and, if so, it depends on the type of hedging, which may be as follows: a) Fair value hedge of assets and liabilities recognized (fair value hedges); b) Hedging of a single risk associated with a recognized asset or liability or a highly probable forecast transaction (cash flow hedge). At the beginning of the transaction, the Company documents the relationship that exists between hedging instruments and those items hedged, as well as their objectives for risk management purposes and the strategy to conduct different hedging operations. The Company also documents its evaluation both at the beginning and at the end of each period if the derivatives used in hedging transactions are highly effective to offset changes in the fair value or in cash flows of hedged items. The fair value of derivative instruments used for hedging purposes is shown in Note 12.3. Changes in the cash flow hedge reserve are classified as a non-current asset or liability if the remaining expiration period of the hedged item is more than 12 months, and as a current asset or liability if the remaining expiration period of the hedged item is less than 12 months. Derivatives that are not designated or do not qualify as hedging derivatives are classified as current assets or liabilities, and changes in the fair value are directly recognized through profit or loss. a) Fair value hedge Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded in profit or loss, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk. The gain or loss relating to the effective portion of interest rate swaps that hedge fixed rate borrowings is recognized in profit or loss within finance costs, together with changes in the fair value of the hedged fixed rate borrowings attributable to interest rate risk. The gain or loss relating to the ineffective portion is recognized in profit or loss within other income or other expenses. If the hedge no longer meets the criteria for hedge accounting, the adjustment to the carrying amount of a hedged item for which the effective interest method is used is amortized to profit or loss over the period to maturity using a recalculated effective interest rate. b) Cash flow hedges The effective portion of the gain or loss on the hedging instrument is initially recognized with a debit or credit to other comprehensive income, while any ineffective portion is immediately recognized with a debit or credit to income, as appropriate depending on the nature of the hedged risk. The amounts accumulated in net equity are carried over to results when the hedged items are settled or when these have an impact on results. When a hedging instrument no longer meets the criteria for hedge accounting, any cumulative deferred gain or loss and deferred costs of hedging in equity at that time remains in equity until the forecast transaction occurs. When the forecast transaction is no longer expected to occur, the cumulative gain or loss and deferred costs of hedging that were reported in equity are immediately reclassified to profit or loss. 3.11 D Derivative financial instruments not considered as hedges are recognized at fair value with the effect in the results of the year. The Company has derivative financial instruments to hedge foreign currency risk exposure. The Company continually evaluates the existence of embedded derivatives in both its contracts and in its financial instruments. As of December 31, 2021, and 2020, the Company does not have any embedded derivatives. 3.12 D Acquisition costs from insurance contracts are classified as prepayments and correspond to insurance contracts in force, recognized using the straight-line method and on an accrual basis independent of payment date. These are recognized under other non-financial assets. 3.13 L (a) Right-of-use assets The Company recognizes right-of-use assets on the initial lease date (i.e., the date on which the underlying asset is available for use). Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, adjusted by any new measurement of the lease liability. The cost of right-of-use assets includes the amount of recognized lease liabilities, direct initial costs incurred and lease payments made on the start date or sooner, less the lease incentives received. Unless the Company is reasonably sure it will take ownership of the leased asset at the end of the lease period, the assets recognized through right-of-use are depreciated in a straight line during the shortest period of their estimated useful life and lease period. Right-of-use assets are subject to impairment. (b) Lease liabilities On the lease start date, the Company recognizes lease liabilities measured at present value of lease payments that will be made during the lease period. Lease payments include fixed payments (including payments that are essentially fixed), less incentives for lease receivables, variable lease payments that are dependent on an index or rate and amounts that are expected to be paid as guaranteed residual value. Lease payments also include the exercise price of a purchase option if the Company is reasonably sure it will exercise this and penalty payments for terminating a lease, if the lease period reflects that the Company will exercise the option to terminate. Variable lease payments that are not dependent on an index or rate are recognized as expenses in the period that produces the event or condition that triggers payment. When calculating the present value of lease payments, the Company uses the incremental borrowing rate on the initial lease date if the interest rate implicit in the lease cannot be determined easily. After the start date, the lease liability balance will increase to reflect the accumulation of interest and will diminish as lease payments are made. Furthermore, the book value of lease liabilities is remeasured in the event of an amendment, a change in the lease period, a change in the fixed lease payments in substance or a change in the assessment to buy the underlying asset. Payments made that affect lease liabilities are presented as part of the financing activities in the cash flow statement. (c) Short-term leases and low-value asset leases The Company applies the short-term lease recognition exemption to leases with a lease term of 12 months or less starting on the start date and that don’t have a purchase option. It also applies the low-value asset lease recognition exemptions to leases less than the limit specified in the respective accounting standard. Lease payments in short-term leases and low-value asset leases are recognized as lineal expenses during the lease term. (d) Significant judgments in the determination of the lease term for contracts with renewal options. The Company determines the lease term as the non-cancellable period of the lease, together with periods covered by an option to extend the lease if it is reasonably certain that this will be exercised, or any period covered by an option to terminate the lease, if it is reasonably certain that this will not be exercised. The Company has the option, under some of its leases, to lease assets for additional terms. The Company applies its judgment when assessing whether it is reasonably certain that it will exercise the option to renovate. In other words, it considers all the relevant factors that create an economic incentive for it to exercise the option to renovate. After the start date, the Company reevaluates the lease term if there is a significant event or change in the circumstances that are under its control and affect its capacity to exercise (or not exercise) the option to renovate. 3.14 I The method used to determine the cost of inventories is the weighted average monthly cost of warehouse storage. In determining production costs for own products, the company includes the costs of labor, raw materials, materials and supplies used in production, depreciation and maintenance of the goods that participate in the production process, the costs of product movement necessary to maintain stock on location and in the condition in which they are found, and also includes the indirect costs of each task such as laboratories, process and planning areas, and personnel expenses related to production, among others. For finished and in-process products, the company has four types of provisions, which are reviewed quarterly: (a) Provision associated with the lower value of stock: The provision is directly identified with the product that generates it and involves three types: (i) provision of lower realizable value, which corresponds to the difference between the inventory cost of intermediary or finished products, and the sale price minus the necessary costs to bring them to the same conditions and location as the product with which they are compared; (ii) provision for future uncertain use that corresponds to the value of those products in process that are likely not going to be used in sales based on the company’s long-term plans; (iii) reprocessing costs of products that are unfeasible for sale due to current specifications. (b) Provision associated with physical differences in inventory: A provision is made for differences that exceed the tolerance considered in the respective inventory process (physical and annual inventories are taken for the productive units in Chile and the port of Tocopilla; the business subsidiaries depend on the last zero ground obtained, but in general it is at least once a year), these differences are recognized immediately. (c) Potential errors in the determination of stock: The company has an algorithm that is reviewed at least once a year and corresponds to diverse percentages assigned to each inventory based on the product, location, complexity involved in the associated measurement, rotation and control mechanisms. (d) Provisions undertaken by business subsidiaries: these are historical percentages that are adjusted as zero ground is attained based on normal inventory management. Inventories of raw materials, materials and supplies for production are recorded at acquisition cost. Cyclical inventories are performed in warehouses, as well as general inventories every three years. Differences are recognized at the moment they are detected. The company has a provision that makes quarterly calculations from percentages associated with each type of material (classification by warehouse and rotation), these percentages use the lower value resulting from deterioration or obsolescence as well as potential losses. This provision is reviewed at least annually, and considers the historical profit and loss obtained in the inventory processes. 3.15 N Non-controlling interests are recorded in the consolidated statement of financial position within equity but separate from equity attributable to the owners of the Parent. 3.16 R Transactions between the Company and its subsidiaries are part of the Company’s normal operations within its scope of business activities. Conditions for such transactions are those normally effective for those types of operations with regard to terms and market prices. The maturity conditions vary according to the originating transaction. 3.17 P Property, plant and equipment are stated at acquisition cost, net of the related accumulated depreciation, amortization and impairment losses that they might have experienced. In addition to the price paid for the acquisition of tangible property, plant and equipment, the Company has considered the following concepts as part of the acquisition cost, as applicable: (a) Accrued interest expenses during the construction period that are directly attributable to the acquisition, construction or production of qualifying assets, which are those that require a substantial period prior to being ready for use. The interest rate used is that related to the project’s specific financing or, should this not exist, the average financing rate of the investor company. (b) The future costs that the Company will have to experience, related to the closure of its facilities at the end of their useful life, are included at the present value of disbursements expected to be required to settle the and its subsequent variation is recorded directly in results. Having initially recognized provisions for closure and refurbishment, the corresponding cost is capitalized as an asset in “Property, plant and equipment” and amortized in line with the amortization criteria for the associated assets. Construction-in-progress is transferred to property, plant and equipment in operation once the assets are available for use and the related depreciation and amortization begins on that date. Extension, modernization or improvement costs that represent an increase in productivity, ability or efficiency or an extension of the useful lives of property, plant and equipment are capitalized as a higher cost of the related assets. All the remaining maintenance, preservation and repair expenses are charged to expense as they are incurred. The replacement of assets, which increase the asset’s useful life or its economic capacity, are recorded as a higher value of property, plant and equipment with the related derecognition of replaced or renewed elements. Gains or losses which are generated from the sale or disposal of property, plant and equipment are recognized as income (or loss) in the period and calculated as the difference between the asset’s sales value and its net carrying value. Costs derived from the daily maintenance of property, plant and equipment are recognized when incurred. 3.18 D Property, plant and equipment are depreciated through the straight-line distribution of cost over the estimated technical useful life of the asset, which is the period in which the Company expects to use the asset. When components of one item of property, plant and equipment have different useful lives, they are recorded as separate assets and depreciated over their expected useful lives. Fixed assets located in the Salar de Atacama consider useful life to be the lesser value between the technical useful life and the years remaining until 2030. In the case of certain mobile equipment, depreciation is performed depending on the hours of operation. The useful lives used for the depreciation and amortization of assets included in property, plant and equipment in years are presented below: Classes of property, plant and equipment Minimum life or Maximum life or Life or average rate Mining assets 3 10 7 Energy generating assets 3 16 9 Buildings 3 25 14 Supplies and accessories 2 10 7 Office equipment 5 10 9 Transport equipment 5 9 7 Network and communication equipment 4 10 5 IT equipment 4 11 7 Machinery, plant and equipment 2 25 13 Other fixed assets 3 20 10 3.19 G Goodwill acquired represents the excess in acquisition cost on the fair value of the Company's ownership of the net identifiable assets of the subsidiary on the acquisition date. Goodwill acquired related to the acquisition of subsidiaries is included in the line item goodwill, which is subject to impairment tests annually or more frequently if events or changes in circumstances indicate that it might be impaired and is stated at cost less accumulated impairment losses. Gains and losses related to the sale of an entity include the carrying value of goodwill related to the entity sold. This intangible asset is assigned to cash-generating units with the purpose of testing impairment losses. It is allocated based on cash-generating units expected to obtain benefits from the business combination from which the aforementioned goodwill acquired arose. 3.20 I Intangible assets other than goodwill mainly relate to water rights, emission rights, commercial brands, costs for rights of way for electricity lines, license costs and the development of computer software and mining property and concession rights, client portfolio and commercial agent. (a) Water rights Water rights acquired by the Company relate to water from natural sources and are recorded at acquisition cost. The Company separates water rights into: i) Finite rights with amortization using the straight-line method, and ii) Indefinite rights, which are not amortized, given that these assets represent rights granted in perpetuity to the Company, which are subject to an annual impairment assessment. (b) Rights of way for electric lines As required for the operation of industrial plants, the Company has paid rights of way in order to install wires for the different electric lines on third party land. These rights are presented under intangible asset. Amounts paid are capitalized at the date of the agreement and amortized in the statement of income, according to the life of the right of way. (c) Computer software Licenses for IT programs acquired are capitalized based on their acquisition and customization costs. These costs are amortized over their estimated useful lives. Expenses related to the development or maintenance of IT programs are recognized as an expense as and when incurred. Costs directly related to the production of unique and identifiable IT programs controlled by the Group, and which will probably generate economic benefits that are higher than its costs during more than a year, are recognized as intangible assets. Direct costs include the expenses of employees who develop information technology software and general expenses in accordance with corporate charges received. The costs of development for IT programs are recognized as assets are amortized over their estimated useful lives. (d) Mining property and concession rights The Company holds mining property and concession rights from the Chilean and Western Australian Governments. Property rights from the State of Chile are usually obtained at no initial cost (other than the payment of mining patents and minor recording expenses) and once the rights on these concessions have been obtained, they are retained by the Company while annual patents are paid. Such patents, which are paid annually, are recorded as prepaid assets and amortized over the following twelve months. Amounts attributable to mining concessions acquired from third parties that are not from the Chilean Government are recorded at acquisition cost within intangible assets. (e) Estimated useful lives or amortization rates used for finite identifiable intangible assets The finite useful life of mining properties is calculated using the productive unit method, except for the mining properties owned by Corfo, which have been leased to the Company and grant it the right to exclusively exploit them until December 31, 2030. The estimated useful life for software which they are amortized corresponds to the periods defined by the contracts or rights from which they originate. f) Minimum and maximum amortization lives or rates of intangible assets: Estimated useful life or amortization rate Minimum Life or Maximum Life or Water rights 5 years Indefinite Rights of way Indefinite Indefinite Corfo Mining properties (1) 9 years 9 years Mining rights Unit-production method Intellectual property 9 years 9 years IT programs 2 years 8 years (1) Mining properties owned by CORFO and leased to the Company, which grant it the exclusive right to exploit them until December 31, 2030. 3.21 R Research and development expenses are charged to profit or loss in the period in which the expenditure was incurred. 3.22 E The Company holds mining concessions for exploration and exploitation of ore, the Company gives the following treatment to expenses associated with exploration and assessment of these resources: Once the rights have been obtained, the Company records the disbursements directly associated with the exploration and evaluation of the deposit in execution as property, plant and equipment (construction in progress) at its cost. These disbursements include the following items: geological surveys, drilling, borehole extraction and sampling, activities related to the technical assessment and commercial viability of the extraction, and in general, any disbursement directly related to specific projects where the objective is to find ore resources. If the technical studies determine that the ore grade is not economically viable, the asset is directly charged to profit and loss. If determined otherwise, the asset described above is associated with the extractable ore tonnage which is amortized as it is used. (a) Limestone and metallic exploration These assets are included in Other Non-Current Non-Financial Assets, and the portion related to the area to be exploited in the year are reclassified to Current Inventory, if applicable. Costs related to metal exploration are charged to profit or loss in the period in which they are recognized if the project assessed doesn't qualify for consideration as advanced exploration otherwise, these are amortized during the development stage. (b) Exploration in Salar de Atacama Exploration expenses in Salar de Atacama are included in non-current assets under Property, Plant and Equipment and are mainly bore holes that can also be used to exploit the deposit or monitoring, which are amortized over 9 years. (c) Exploration and evaluation at the Mt. Holland Project Mount Holland exploration and evaluation expenditure is included in Property, plant and equipment, specifically in Construction in Progress. See Note 1. 8. 3.23 I Assets subject to depreciation and amortization are also subject to impairment testing, p

Disclosure Of Financial Risk Management Explanatory [Abstract]
Disclosure of financial risk management [text block]	Note 4 F 4.1 F The Company’s financial risk management policy is focused on safeguarding the stability and sustainability of the Company and its subsidiaries with regard to all such relevant financial uncertainty components. The Company’s operations are subject to certain financial risk factors that may affect its financial position or results. The most significant risk exposures are market risk, liquidity risk, currency risk, credit risk, and interest rate risk, among others. There could also be additional risks, which are either unknown or known but not currently deemed to be significant, which could also affect the Company’s business operations, its business, financial position, or profit or loss. The financial risk management structure includes identifying, determining, analyzing, quantifying, measuring and controlling these events. Management and in particular, Finance Management, is responsible for constantly assessing the financial risk. 4.2 R (a) Credit risk A global economic contraction may have potentially negative effects on the financial assets of the Company, which are primarily made up of financial investments and trade receivables, and the impact on of our customers could extend the payment terms of the Company's receivables by increasing its exposure to credit risk. Although measures are taken to minimize the risk, this global economic situation could mean losses with adverse material effects on the business, financial position or profit and loss of the Company's operations. Trade receivables: to mitigate credit risk, the Company maintains active control of collection and requires the use of credit insurance. Credit insurance covers the risk of insolvency and unpaid invoices corresponding to 80% of all receivables with third parties. The credit risk associated with receivables is analyzed in Note 12.2 b) and the related accounting policy can be found in Note 3.6. Bank Notes: These are negotiable promissory notes issued by a bank payable at maturity. They are accepted based on the credit quality of the issuing banks. No significant modifications have been made during the period to risk models or parameters used in comparison to December 31, 2020, and no modifications have been made to contractual cash flows that have been significant during this period. Financial investments: correspond to time deposits whose maturity date is greater than 90 days and less than 360 days from the date of investment, so they are not exposed to excessive market risks. The counterparty risk in implementation of financial operations is assessed on an ongoing basis for all financial institutions in which the Company holds financial investments.

However, the global nature of the Company's business generates an exposure to exchange rate variations of several currencies with the US dollar. Therefore, the Company maintains hedge contracts to mitigate the exposure generated by its main mismatches (net between assets and liabilities) in currencies other than the US dollar against the exchange rate variation, updating these contracts periodically depending on the amount of mismatching to be covered in these currencies. Occasionally, subject to the approval of the Board, the Company ensures short-term cash flows from certain specific line items in currencies other than the US dollar. A significant portion of the Company’s costs, especially salary payments, is associated with the Peso. Therefore, an increase or decrease in its exchange rate with the US dollar will provoke a respective decrease or increase to these accounting costs, which would be reflected in the Company’s profit and loss. By the fourth quarter of 2021, approximately US$ 530 million accumulated in expenses are associated with the Peso. As of December 31, 2021, the Company held derivative instruments classified as hedges of foreign exchange risks associated with 100% of all of the bond liabilities denominated in UF, for a liability at fair value of US$ 81.85 million, this significant variation is explained primarily by the USD/CLP exchange rate observed at the end of the period. As of December 31, 2020, an asset was recognized amounting to US$ 18.41 million. Furthermore, on of December 31, 2021, the Company held derivative instruments classified as hedges of foreign exchange risks associated with 100% of all nominative term deposits in UF and in pesos, at a fair value of US$ 12.61 million in assets. On December 31, 2020, a liability was recognized for an amount of US$ 21 million. The Company had the following derivative contracts as of December 31, 2021 (at the absolute value of the sum of their notional values), to hedge the difference between its assets and liabilities: US$ 85.25 CLP/US dollar derivative contracts, US$ 60.98 Euro/US dollar derivative contracts, US$ 37.07 million in South African rand/US dollar derivative contracts, US$ 207.64 million in Chinese renminbi/US dollar derivative contracts, US$ 57.51 million in Australian dollar/US dollar derivative contracts and US$ 11.95 million in other currencies. These derivative contracts are held with domestic and foreign banks, which have the following credit ratings. Financial institution Financial assets Rating Moody´s S&P Fitch Banco Estado Derivative P-1 A-1 - Merrill Lynch International Derivative - A+ AA Banco Itaú-Corpbanca Derivative P-2 A-2 - JP Morgan Derivative Aa2 A+ AA Morgan Stanley Derivative A+ BBB+ A The Bank of Nova Scotia Derivative A A- AA- (c) Interest rate risk Interest rate fluctuations, primarily due to the uncertain future behavior of markets, may have a material impact on the financial results of the Company. Significant increases in the rate could make it difficult to access financing at attractive rates for the Company's investment projects. The Company maintains current and non-current financial debt at fixed rates and LIBOR rate plus spread. As of December 31, 2021, the Company has 2.7% of its financial liabilities linked to variations in the LIBOR rate. 100% of these obligations are covered by derivative instruments classified as interest rate hedging; therefore, a significant rate increase would not impact our financial condition. (d) Liquidity risk Liquidity risk relates to the funds needed to comply with payment obligations. The Company’s objective is to maintain financial flexibility through a comfortable balance between fund requirements and cash flows from regular business operations, bank borrowings, bonds, short term investments, and marketable securities, among others. For this purpose, the Company keeps a high liquidity ratio 1 The Company has an important capital expense program which is subject to change over time. On the other hand, world financial markets go through periods of contraction and expansion that are unforeseeable in the long-term and may affect The Company’s access to financial resources. Such factors may have a material adverse impact on the Company’s business, financial position and results of operations. The Company constantly monitors the matching of its obligations with its investments, taking due care of maturities of both, from a conservative perspective, as part of this financial risk management strategy. As of December 31, 2021, the Company had unused, available revolving credit facilities with banks, for a total of US$ 489 million. The position in other cash and cash equivalents are invested in highly liquid mutual funds with an AAA risk rating. 1 All current assets divided by all current liabilities.

These methods are consistent with the risk management profile of the SQM Group. See Note 12.8.

The objective is to hedge the exchange rate and inflation financial risks associated with bonds payable. Hedges are documented and tested to measure their effectiveness. Based on a comparison of critical terms, hedging is highly effective, given that the hedged amount is consistent with obligations maintained for bonds denominated in Pesos and UF. Likewise, hedging contracts are denominated in the same currencies and have the same maturity dates of bond principal and interest payments. 12.4 F Other current and non-current financial liabilities As of December 31, 2021 and 2020, the detail is as follows: As of December 31, 2021 As of December 31, 2020 Other current and non-current financial Currents Non-Current Total Currents Non-Current Total ThUS$ ThUS$ ThUS$ ThUS$ ThUS$ ThUS$ Liabilities at amortized cost Bank borrowings 85 69,613 69,698 82 69,376 69,458 Obligations with the public 40,594 2,445,219 2,485,813 36,781 1,816,626 1,853,407 Derivative financial instruments For hedging 8,954 72,900 81,854 26,699 13,511 40,210 Non-Hedging 1,672 - 1,672 5,393 - 5,393 Total 51,305 2,587,732 2,639,037 68,955 1,899,513 1,968,468 Current and non-current bank borrowings As of December 31, 2021 and 2020, the detail is as follows: Current and non-current bank borrowings As of December 31, 2021 As of December 31, 2020 ThUS$ ThUS$ Current borrowings 85 82 Non-current borrowings 69,613 69,376 Current and non-current bank borrowings 69,698 69,458 a) Bank borrowings, current: As of December 31, 2021, and 2020, the detail of this caption is as follows: Debtor Creditor Tax ID No. Company Country Tax ID No. Financial Country Currency or Payment of Repayment Effective rate Nominal rate 93.007.000-9 SQM S.A.

Disclosure of employee benefits [text block]	Note 17 E 17.1 P Classes of benefits and expenses by employee As of December 31, 2021 As of December 31, 2020 ThUS$ ThUS$ Current Profit sharing and bonuses 1,383 7,770 Performance bon u 25,392 1,326 Total 26,775 9,096 Non-current Profit sharing and bonuses - - Severance indemnity payments 27,099 32,199 Total 27,099 32,199 17.2 P This policy is applied to all benefits received for services provided by the Company's employees. This is divided as follows: a) Short-term benefits for active employees are represented by salaries, social welfare benefits, paid time off, sickness and other types of leave, profit sharing and incentives and non-monetary benefits; e.g., healthcare service, housing, subsidized or free goods or services. These will be paid in a term which does not exceed twelve months. The Company maintains incentive programs for its employees, which are calculated based on the net result at the close of each period by applying a factor obtained from an evaluation based on their personal performance, the Company’s performance and other short-term and long-term indicators. b) Staff severance indemnities are agreed and payable based on the final salary, calculated in accordance with each year of service to the Company, with certain maximum limits in respect of either the number of years or in monetary terms. In general, this benefit is payable when the employee or worker ceases to provide his/her services to the Company and there are a number of different circumstances through which a person can be eligible for it, as indicated in the respective agreements; e.g. retirement, dismissal, voluntary retirement, incapacity or disability, death, etc. See Note 17.3. c) Obligations after employee retirement, described in Note 17.4. d) Retention bonuses for a group of Company executives, described in Note 17.6. 17.3 O The actuarial assessment method has been used to calculate the Company’s obligations with respect to staff severance indemnities, which relate to defined benefit plans consisting of days of remuneration per year served at the time of retirement under conditions agreed in the respective agreements established between the Company and its employees. Under this benefit plan, the Company retains the obligation to pay staff severance indemnities related to retirement, without establishing a separate fund with specific assets, which is referred to as not funded Benefit payment conditions The staff severance indemnity benefit relates to remuneration days for years worked for the Company without a limit being imposed in regard of amount of salary or years of service. It applies when employees cease to work for the Company because they are made redundant or in the event of their death. This benefit is applicable up to a maximum age of 65 for men and 60 for women, which are the usual retirement ages according to the Chilean pensions system as established in Decree Law 3,500 of 1980. Methodology The determination of the defined benefit obligation is made under the requirements of IAS 19 “Employee benefits”. 17.4 P Our subsidiary SQM NA, together with its employees established a pension plan until 2002 called the “SQM North America Retirement Income Plan”.

Our subsidiary SQM Salar holds exclusive rights to exploit the mineral resources in an area covering approximately 140,000 hectares of land in the Salar de Atacama in northern Chile, of which SQM Salar is only entitled to exploit the mineral resources in 81,920 hectares. These rights are owned by Corfo and leased to SQM Salar pursuant to the Lease Agreement. Corfo cannot unilaterally amend the Lease Agreement and the Project Agreement, and the rights to exploit the resources cannot be transferred. The Lease Agreement establishes that SQM Salar is responsible for making quarterly lease payments to Corfo according to specified percentages of the value of production of minerals extracted from the Salar de Atacama brines, maintaining Corfo’s rights over the Mining Exploitation Concessions and making annual payments to the Chilean government for such concession rights. The Lease Agreement was entered into in 1993 and expires on December 31, 2030. On January 17, 2018, SQM and CORFO reached an agreement to end an arbitration process directed by the arbitrator, Mr. Héctor Humeres Noguer, in case 1954-2014 of the Arbitration and Mediation Center of Santiago Chamber of Commerce and other cases related to it. The agreement signed in January 2018, includes important amendments to the lease agreement and project agreement signed between CORFO and SQM in 1993. The main modifications became effective on April 10, 2018 and requires an increase in the lease payments by increasing the lease rates associated with the sale of the different products produced in the Salar de Atacama, including lithium carbonate, lithium hydroxide and potassium chloride. This agreement has been amended since it was signed, and it is reasonable to expect that it will continue to be amended as mutually agreed by the parties. Additionally, SQM Salar commits to contribute to research and development efforts, as well as to the communities in close proximity to the Salar de Atacama and provide a percentage of total annual sales of SQM Salar to regional development. SQM Salar commits to contribute between US$10.8 million and US$18.9 million per year to research and development efforts, between US$10 to US$15 million per year to the communities in close proximity to the Salar de Atacama, and 1.7% of total annual sales of SQM Salar to regional development 18.3 O Description of other liabilities As of December 31, 2021 As of December 31, 2020 ThUS$ ThUS$ Tax withholdings 21,546 1,208 VAT payable 26,111 1,642 Guarantees received 746 2,636 Accrual for dividend 34,184 8,027 Monthly tax provisional payments 23,319 8,407 Deferred income 5,605 6,435 Withholdings from employees and salaries payable 5,587 5,017 Accrued vacations (1) 23,467 24,003 Other current liabilities 1,109 3,580 Total 141,674 60,955 (1) Vacation benefit (short-term benefits to employees, current) is in line with the provisions established in Chile’s Labor Code, which indicates that employees with more than a year of service will be entitled to annual vacation for a period of at least fifteen paid business days.

Disclosure of detailed information about controls capital management [Abstract]
Disclosure of issued capital [text block]	Note 19 D The detail and movements in the funds of equity accounts are shown in the consolidated statement of changes in equity. 19.1 C The main object of capital management relative to the administration of the Company’s financial debt and equity is to ensure the regular conduct of operations and business continuity in the long term, with the constant intention of maintaining an adequate level of liquidity and in compliance with the financial safeguards established in the debt contracts in force. Within this framework, decisions are made in order to maximize the value of the company. Capital management must comply with, among others, the limits contemplated in the Financing Policy approved by the Shareholders’ Meeting, which establish a maximum consolidated indebtedness level of 1.5 times the debt to equity ratio. This limit can be exceeded only if the Company’s management has first obtained express approval at an Extraordinary Shareholders’ Meeting. The Company’s management controls capital management based on the following ratios: Capital Management As of December As of December Description (1) Calculation (1) Net Financial Debt (ThUS$) 204,692 1,074,020 Financial Debt – Financial Resources Other current Financial Liabilities + Other Non-Current Financial Liabilities– Cash and Cash Equivalents – Other Current Financial Assets – Hedging Assets, non-current Liquidity 4.62 5.40 Current Assets divided by Current Liabilities Total Current Assets / Total Current Liabilities ROE 18.41 % 7.79 % Profit for the year divided by Total Equity Profit for the year / Equity Adjusted EBITDA (ThUS$) 1,185,453 579,765 Adjusted EBITDA Profit (loss) + Depreciation and Amortization Expenses adjustments + Finance Costs + Income Tax – Other income and Share of profit of associates and joint ventures + Other expenses by function – Finance income – Currency differences EBITDA (ThUS$) 1,140,086 524,650 EBITDA Profit (loss) + Depreciation and Amortization Expense adjustments + Finance Costs + Income Tax ROA 21.29 % 9.83 % Adjusted EBITDA – Depreciation divided by Total Assets net of financial resources less related parties’ investments (Gross Profit – Administrative Expenses)/ (Total Assets – Cash and Cash Equivalents – Other Current Financial Assets – Other Non-Current Financial Assets – Equity accounted Investments) (LTM) Indebtedness 0.06 0.50 Net Financial Debt on Equity Net Financial Debt / Total Equity The Company’s capital requirements change according to variables such as: working capital needs, new investment financing and dividends, among others. The SQM Group manages its capital structure and makes adjustments bases on the predominant economic conditions so as to mitigate the risks associated with adverse market conditions and take advantage of the opportunities there may be to improve the liquidity position of the SQM Group. There have been no changes in the capital management objectives or policy within the years reported in this document, no breaches of external requirements of capital imposed have been recorded. There are no contractual capital investment commitments. 19.2 O Bond issuance contracts in the local market require the Company to maintain a Total Borrowing Ratio no higher than 1 for Series H, Series O and Series Q bonds, calculated over the last consecutive 12 months. Capital management must ensure that the Borrowing Ratio remains below 1.0, with respect to the Series H, Series O and Series Q bonds. This ratio was redefined at the Bondholders' Meeting held in September 2020, as the result of dividing Net Financial Debt by the company's Total Equity. Previously it had been defined as Total Liabilities divided by Equity, and the limit for this ratio was 1.44, with a prepayment option for bondholders if this ratio rose above 1.2. As of December 31, 2021 and 2020 this ratio was 0.06. The financial restrictions with respect to the bonds issued by the Company for the periods ended December 31, 2021 and 2020 are as follows.

The Company is also committed to provide quarterly financial information. The Company and its subsidiaries are complying with all the aforementioned limitations, restrictions and obligations. 19.3 D Issued share capital is divided into Series A shares and Series B shares. All such shares are nominative, have no par value and are fully issued, subscribed and paid. Series B shares may not exceed 50% of the total issued, subscribed and paid-in shares of the Company and have a limited voting right, in that all of them can only elect one director of the Company, regardless of their equity interest and preferences: (a) require the calling of an Ordinary or Extraordinary Shareholders' Meeting when so requested by Series B shareholders representing at least 5% of the issued shares thereof; and (b) require the calling of an extraordinary meeting of the board of directors, without the president being able to qualify the need for such a request, when so requested by the director who has been elected by the shareholders of said Series B. The limitation and preferences of Series B shares have a duration of 50 consecutive and continuous years as of June 3, 1993. The Series A shares have the preference of being able to exclude the director elected by the Series B shareholders in the voting process in which the president of the board of directors and of the Company must be elected and which follows the one in which the tie that allows such exclusion resulted. The preference of the Series A shares will have a term of 50 consecutive and continuous years as of June 3, 1993. The form of the titles of the shares, their issuance, exchange, disablement, loss, replacement, assignment and other circumstances thereof shall be governed by the provisions of Law No, 18,046 and its regulations.

Dividend policy for commercial year 2021 Company’s dividend policy for the 2021 business year was agreed upon by the Board of Directors on April 23, 2021. This dividend policy was amended on November 17, 2021, and establishes the following: (a) Distribute and pay to the corresponding shareholders, a percentage of the net income that shall be determined per the following financial parameters as a final dividend: (i) 100% of the profit for 2021 if all the following financial parameters are met: (a) “all current assets” divided by “all current liabilities” is equal to or greater than 2.5 times, and (b) the sum of “all current liabilities” and “all non-current liabilities”, less “cash equivalents”, less “other current financial assets”, all of the above divided by “total equity” in equal or less than 0.85 times. (ii) 80% of the profit for 2021 if all the following financial parameters are met: (a) “all current assets” divided by “all current liabilities” is equal to or greater than 2.0 times, and (b) the sum of “all current liabilities” and “all non-current liabilities”, less “cash equivalents”, less “other current financial assets”, all of the above divided by “total equity” in equal or less than 0.95 times. (iii) 60% of the profit for 2021 if all the following financial parameters are met: (a) “all current assets” divided by “all current liabilities” is equal to or greater than 1.5 times, and (b) the sum of “all current liabilities” and “all non-current liabilities”, less “cash equivalents”, less “other current financial assets”, all of the above divided by “total equity” in equal or less than 1.05 times. (iv) If none of the foregoing financial parameters are met, the Company shall distribute and pay, as a final dividend, and in favor of the respective shareholders, 50% of the 2021 net income. (b) Distribute and pay two interim dividends during 2021, which will be charged to the final dividend indicated above against retained earnings reflected in the financial statements as of March 31, 2021 and June 30, 2021, by the percentage that corresponds according to the financial parameters expressed in (a) above. On May 19, 2021 and August 18, 2021, the Board of Directors agreed to distribute and pay an interim dividend equivalent to US$ 0.23797 per share and US$ 0.31439 per share, respectively, out of the Company's earnings for 2021. These amounts were paid in Chilean peso equivalents at the official US dollar exchange rate on May 28, 2021 and September 1, 2021, respectively (the "Interim Dividends") (c) The Board of Directors will not distribute any other interim dividends out of 2021 earnings. (d) At the ordinary meeting to be held in 2022, the Company's Board of Directors will propose a final dividend in line with the percentage corresponding to the financial parameters outlined in (a) above, discounting the provisional dividends and the Interim Dividends. In the event that the amount equivalent to the percentage of the 2021 distributable earnings as described in (a) above is equal to or less than the sum of the Potential Dividend and the Interim Dividends, then no additional amount will be distributed and the Interim Dividends will be deemed to be paid as a final dividend. In any case, the final dividend may not be less than the minimum legal dividend required by law or the bylaws. (e) Any remaining amount from the net profits from 2021 can be retained and used to finance the Company’s own operations or one or more of its investment projects, notwithstanding a possible distribution of dividends charged to accumulated profit that might be approved by the shareholders’ meeting or the possible future capitalization of all or part of it. (f) The payment of additional dividends is not being considered. It must be expressly stated that this dividends policy details the intention of the Company’s Board of Directors and its fulfillment depends on the actual profits obtained, as well as on the results indicated by the projections the Company makes from time to time or on the existence of particular conditions, as appropriate. In any case, if the dividend policy set forth by the Board of Directors should undergo any substantial change, the Company must communicate it as a material event. 19.6 I On May 19, 2021, the Board of Directors agreed to pay a provisional dividend equivalent to US$ 0.23797 per share with a charge to Company earnings for 2021.

Disclosure of contingent liability [Abstract]
Disclosure of contingent liabilities	Note 20 C In accordance with note 18.1, the Company recognizes a provision for those lawsuits in which there is a probability that the judgments will be unfavorable to the Company. The Company is party to the following lawsuits and other relevant legal actions: 20.1 L (a) In August 1996, Nitratos Naturais do Chile Ltda. was fined by Fazenda do Estado de Sao Paulo for concluding activities without attaching the necessary documentation for submission to the competent authorities. The treasury of the State of Sao Paulo initiated legal actions to collect close to ThUS$ 492. Nitratos Naturais do Chile has presented a case to the federal court of Brazil to request a reduction in the fine, which is currently pending. (b) In August 2004, Nitratos Naturais do Chile Ltda. was fined by Fazenda do Estado de Sao Paulo for failing to report trade activities. The treasury of the State of Sao Paulo initiated legal actions to collect close to ThUS$ 265. In 2018, the Court of Appeals agreed to a reduction in the fine and the Fazenda do Estado de Sao Paulo appealed to the Court of Brazil, and this appeal is still pending. (c) In December 2010, the city of Pomona in the state of California, United States, filed a claim against SQM NA, which was heard before the US District Court for the Central District of California. The plaintiff requested the payment of expenses and other values related to treatment of groundwater to make it apt for consumption, which involved the extraction of perchlorate in this water, which allegedly came from Chilean fertilizers, for an approximate amount of US$ 30 million. On January 27, 2022, a judgment was issued against SQM NA for MUS$ 48.1, which has been appealed. The Company has recorded a charge of MUS$ 48.1 before taxes to the income statement for the year ended December 3 1 (d) In December 2010, the city of Lindsay in California, United States, filed a claim against SQM NA, which was heard before the US District Court for the Central District of California. The plaintiff requested the payment of expenses and other values related to treatment of groundwater to make it apt for consumption, which involved the extraction of perchlorate in this water, which allegedly came from Chilean fertilizers, the trial is currently suspended. (e) In May 2014, a claim of compensation for damages was filed against SQM Nitratos for its alleged extracontractual liability derived from an explosion occurring in 2010 in the vicinity of the town of Baquedano, which caused the death of six workers. The portion of the claim that has not been settled in court is approximately MUS$ 1.2. On May 7, 2019, the 18th Civil Court of Santiago dismissed the claim. The case currently is in the Santiago Court of Appeals, which will make a determination on the motion for appeal and cassation brought about on behalf of the plaintiff. (f) In January 2018, the company Transportes Buen Destino S.A. filed an arbitration claim under CAM rules against SQM Salar for controversies resulting from the execution of transport contracts for lithium brine and transport of salts. The amount of the claim is close to MUS$ 3. The arbitration is currently in the evidence stage. (g) In September 2018, representatives Claudia Nathalie Mix Jiménez, Gael Fernanda Yeomans Araya, Camila Ruzlay Rojas Valderrama filed a public right annulment suit against Corfo regarding the Salar de Atacama Project Contract signed between Corfo and SQM Salar. The Company has intervened as an independent third party. This discussion stage has concluded. For more information, see Note 20.4. (h) The Company and FPC Ingeniería y Construcción SpA were sued in May 2019 for compensation for damages resulting from alleged extracontractual liability derived from the traffic accident occurring on March 5, 2018, involving the overturn of a truck owned by FPC and the subsequent death of its two occupants, both employees of FPC. The four children of one of the deceased workers are the plaintiffs in this case and are seeking compensation for moral damages. The case is in the 19th Civil Court of Santiago and is in the evidence stage. The amount of the claim is close to MUS$ 1.2. (i) The company Arrigoni Ingeniería y Construcción S.A. filed a claim in November 2019 against SQM Salar in arbitration court under CAM rules, requesting the conclusion of the Works Contract known as “Expansion of Lithium Carbonate Plant Phase II.” The trial is currently in the evidence stage. The amount of the claim is close to MUS$ 14.6. (j) The Company has initiated an arbitration process against the company Sierra Gorda S.C.M. due to controversies originating from the Mining, Royalties and Other Sales Contract dated December 16, 2011. Sierra Gorda S.C.M. has filed counterclaims against the Company. The process is in its evidence stage. The counterclaims filed against the Company amount to MUS$ 46. (k) Through resolution dated April 14, 2020, the General Water Bureau (DGA) fined SQM Salar S.A. an amount of 4,180 UTM for the alleged violation of article 294 of the Water Code. This resolution was appealed for reconsideration as established in article 136 of the Water Code, and its resolution is currently pending. (l) On January 7, 2021, the Company Ocaña y Vega Limited has requested arbitration against the Company to claim compensation for damages associated with the early termination of two construction contracts. The case has reached the evidence gathering stage. The cost of arbitration is valued at approximately ThUS$ 377. (m) On April 6, 2021, Empresa Eléctrica Cochrane SpA requested the constitution of arbitration to resolve a dispute in relation to electricity supply contracts signed on March 30, 2012, and February 1, 2013. The trial is currently in the discussion stage. On January 17, 2022, the Company filed a claim for early termination of the electricity supply contracts against Empresa Eléctrica Cochrane SpA. at the same arbitration tribunal. (n) In October 2021, the Company requested the constitution of an arbitration against Chilena Consolidada Seguros Generales S.A. to resolve differences in relation to the interpretation and execution of the directors' and officers' liability insurance policy. The lawsuit has been notified to the arbitrator. (o) In February 2022, the company Montajes Eléctricos y Construcciones RER Limitada filed a claim for damages before the 21st Civil Court of Santiago against SQM Industrial S.A. for its alleged liability derived from the breach of an electrical installation contract. The case is still in the discussion stage. The amount of the lawsuit is approximately ThUS$ 542. The Company and its subsidiaries have been involved and will probably continue to be involved either as plaintiffs or defendants in certain judicial proceedings that have been and will be heard by the arbitration or ordinary courts of justice that will make the final decision. Those proceedings that are regulated by the appropriate legal regulations are intended to exercise or oppose certain actions or exceptions related to certain mining claims either granted or to be granted and that do not or will not affect in an essential manner the development of the Company and its subsidiaries. Soquimich Comercial S.A. has been involved and will probably continue being involved either as plaintiff or defendant in certain judicial proceedings through which it intends to collect and receive the amounts owed, the total nominal value of which is approximately MUS$ 1.05. The Company and its subsidiaries have made efforts and continues making efforts to obtain payment of certain amounts that are still owed to the Company due to its activities. Such amounts will continue to be required using judicial or non-judicial means by the plaintiffs, and the actions and exercise related to these are currently in full force and effect. 20.2 E The SMA issued a resolution dated November 28, 2016, rectified by a resolution dated December 23, 2016, which filed charges against SQM Salar for brine extraction in excess of authorized amounts, progressive impairment of the vitality of carob trees, providing incomplete information modification of follow-up plan variables, and other charges. SQM Salar S.A. presented a compliance program that was accepted by the SMA. On December 2019, the Environmental Court of Antofagasta rendered the accepted compliance program null. In October 2020, the SMA formulated new observations for the compliance program, which will enable the incorporation of improvements in line with the ruling of the Environmental Court of Antofagasta, to then make a determination regarding approval or rejection. If a new compliance program is not approved by the SMA, or if approved and legally challenged and rendered null and void by the Chilean courts, the sanction process against SQM Salar could be resumed. This latter event may consider the application of fines up to MUS$9, temporary or permanent closure of facilities and in extreme circumstances, revocation of the respective environmental permit. 20.3 T SQM Salar has filed three tax claims against the SII for taxes levied between tax years 2012 and 2018 (business years 2011 to 2017). The SII has sought to broaden the application of the specific tax on mining activities to the extraction of lithium, a substance that is not concessionable by law. The amount associated with these processes totals US$ 90.4 million, which has been paid by SQM Salar. This amount is recorded under “Non-current tax assets” in the Consolidated Statement of Financial Position of the Company as of December 3 1 The non-current tax assets presented in the Company’s Financial Statements as of December 31, 2021 of US$ 90.4 million, correspond to the three claims in the recently mentioned dispute. This amount can be broken down as follows: overcharged amount of US$ 18.9 million; potential specific tax for lithium amounting to US$ 48.6 million (minus effect on first category income tax) and interests associated with this tax for US$ 22.8 million. The details of the claims can be found below: (a) On August 26, 2016, a tax claim was filed with the Third Tax and Customs Court of the Metropolitan Region against tax assessments No. 169, 170, 171 and 172 for tax years 2012 to 2014. The amount in dispute is US$ 17.8 million, of which (i) US$ 11.5 million correspond to the contested tax (minus effect on first category income tax), and (ii) US$ 6.3 (b) On March 24, 2017, a tax claim was filed with the Third Tax and Customs Court of the Metropolitan Region against tax assessment No. 207 and resolution No. 156, both issued by the SII, for tax years 2015 to 2016. The amount in dispute is US$ 8.6 million, of which (i) US$ 1.3 million correspond to amounts assessed in excess, (ii) US$ 6.9 million correspond to the contested tax (minus effect on first category income tax), and (ii) US$ 0.5 million correspond to interest and fines. On November 28, 2018, the Third Tax and Customs Court rejected the corresponding claim, and the case is currently in the Santiago Court of Appeals. (c) On July 15, 2021, SQM Salar filed a public right annulment suit and tax claim with the First Tax and Customs Court of the Metropolitan Region against tax assessments No. 65 and 66 for the 2017 and 2018 tax years. The amount in dispute is US$ 63.9 million, of which (i) US$ 17.7 million correspond to overcharged amounts, (ii) US$ 30.2 million correspond to the contested tax (minus effect on first category income tax), and (iii) US$ 16.1 million correspond to interest and fines. This case is under deliberation. The SII has not issued an assessment claiming differences in the specific tax on mining activities filed for tax years 2019 onward. If the SII uses criteria similar to that used in previous years, it may issue an assessment in the future for this period. The Company estimates a potential assessment of US$ 79.8 million (minus effect on first category income tax) by the SII, without considering interests and fines. To date, the Company has recorded no effect corresponding to this tax on its profit and loss. 20.4 C On September 6, 2018, representatives Claudia Nathalie Mix Jiménez, Gael Fernanda Yeomans Araya and Camila Ruslay Rojas Valderrama and the Poder Ciudadano political party filed an annulment suit against Corfo, which requested that the Salar de Atacama Project Agreement between Corfo and the Company, SQM Potasio and SQM Salar be annulled. The Companies have taken part of the process as interested third parties. In the event that the annulment claim is approved for the Salar de Atacama Project Agreement, SQM Salar may be prevented from the exploitation of the mining assets in the Salar de Atacama that it has leased from Corfo. 20.5 C Due to differences between shareholders of the company Abu Dhabi Fertilizer Industries Company, diverse lawsuits have arisen that may result in claims against SQM Corporation N.V. and by this company against the other shareholders. These disputes may materially affect the value of the investment of the Company in Abu Dhabi Fertilizer Industries Company. At this time, it is not possible to quantify the amounts of these claims. 20.6 R The subsidiary Isapre Norte Grande Ltda., in compliance with the provisions established by the Chilean Superintendence of Healthcare, which regulates the running of pension-related health institutions, maintains a guarantee in financial instruments delivered in deposits, custody and administration to Banco de Chile. This guarantee, according to the regulations issued by the Chilean Superintendence of Healthcare is equivalent to the total amount owed to its members and medical providers, Banco de Chile reports the present value of the guarantee to the Chilean Superintendence of Healthcare and Isapre Norte Grande Ltda on a daily basis. As of December 31, 2021, the guarantee amounts to ThUS$ 622. 20.7 S The main security received (exceeding ThUS$ 100) from third parties to guarantee Soquimich Comercial S.A. their compliance with obligations in contracts of commercial mandates for the distribution and sale of fertilizers amounted to ThUS$ 8,866 and ThUS$ 10,114 on December 31, 2021 and 2020 respectively; which is detailed as follows: Grantor Relationship As of December 31, 2021 As of December 31, 2020 ThUS$ ThUS$ Ferosor Agrícola S.A.

Disclosure of entity's operating segments [Abstract]
Disclosure Of Entitys Reportable Segments Explanatory [Text Block]	Note 22 R 22.1 R (a) General information: The amount of each item presented in each operating segment is equal to that reported to the highest authority that makes decisions regarding the operation, in order to decide on the allocation of resources to the defined segments and to assess its performance. These operating segments mentioned are consistent with the way the Company is managed and how results will be reported by the Company. These segments reflect separate operating results that are regularly reviewed by the executive responsible for operational decisions in order to make decisions about the resources to be allocated to the segment and assess its performance (See Note 22.2). The performance of each segment is measured based on net income and revenues. Inter-segment sales are made using terms and conditions at current market rates. (b) Factors used to identify segments on which a report should be presented: The segments covered in the report are strategic business units that offer different products and services. These are managed separately because each business requires different technology and marketing strategies. (c) Description of the types of products and services from which each reportable segment obtains its income from ordinary activities The operating segments, which obtain income from ordinary activities, generate expenses and have its operating results reviewed on a regular basis by the highest authority who makes decisions regarding operations, relate to the following groups of products: (i) Specialty plant nutrients (ii) Iodine and its derivatives (iii) Lithium and its derivatives (iv) Industrial chemicals (v) Potassium (vi) Other products and services (d) Description of income sources for all the other segments Information regarding assets, liabilities, profits and expenses that cannot be assigned to the segments indicated above, due to the nature of production processes, is included under the "Unallocated amounts” category of the disclosed information. (e) Description of the nature of the differences between measurements of results of reportable segments and the result of the entity before the expense or income tax expense of incomes and discontinued operations The information reported in the segments is extracted from the Company’s consolidated financial statements and therefore there is no need to prepare reconciliations between the data mentioned above and those reported in the respective segments, according to what is stated in paragraph 28 of IFRS 8, "Operating Segments". For the allocation of inventory valuation costs, we identify the direct expenses (can be directly allocated to products) and the common expenses (belong to coproduction processes, for example common leaching expenses for production of Iodine and Nitrates), Direct costs are directly allocated to the product and the common costs are distributed according to percentages that consider different variables in their determination, such as margins, rotation of inventories, revenue, production etc. The allocation of other common costs that are not included in the inventory valuation process, but go straight to the cost of sales, use similar criteria: the costs associated with a product or sales in particular are assigned to that particular product or sales, and the common costs associated with different products or business lines are allocated according to the sales. (f) Description of the nature of the differences between measurements of assets of reportable segments and the Company´s assets Assets are not shown classified by segments, as this information is not readily available, some of these assets are not separable by the type of activity by which they are affected since this information is not used by management in decision-making with respect to resources to be allocated to each defined segment. All assets are disclosed in the "unallocated amounts" category. (g) Description of the nature of the differences between measurements of liabilities of reportable segments and the Company’s liabilities Liabilities are not shown classified by segments, as this information is not readily available, some of these liabilities are not separable by the type of activity by which they are affected, since this information is not used by management in decision-making regarding resources to be allocated to each defined segment. All liabilities are disclosed in the "unallocated amounts" category. 22.2 R Operating segment items as of December 31, 2021 Specialty Iodine and its Lithium and Industrial Potassium Other Reportable Operating Unallocated Total as of ThUS$ ThUS$ ThUS$ ThUS$ ThUS$ ThUS$ ThUS$ ThUS$ ThUS$ ThUS$ Revenue 908,815 437,931 936,121 132,011 416,592 30,845 2,862,315 2,862,315 -

Based on IAS 12, paragraph 81, letter “c”, the company has estimated that the method that discloses the most significant information for users of the financial statements is the numeric conciliation between the tax benefit (expense) and the result of multiplying the accounting profit by the current rate in Chile. The aforementioned choice is based on the fact that the Company and subsidiaries established in Chile generate a large part of the Company’s tax benefit (expense). The amounts provided by subsidiaries established outside Chile have no relative importance in the overall context. Reconciliation between the tax benefit (expense) and the tax calculated by multiplying income before taxes by the Chilean corporate income tax rate.

Tax audits, due to their nature, are often complex and may require several years. Below, we provide a summary of tax periods that are potentially subject to verification, in accordance with the tax regulations in force in the country of origin: (i) Chile According to article 200 of Decree Law No 830, the taxes will be reviewed for any deficiencies in terms of payment and to generate any taxes that might arise. There is a 3-year prescriptive period for such review, dating from the expiration of the legal deadline when payment should have been made. This prescriptive period can be extended to 6 years for the revision of taxes subject to declaration, when such declaration has not been filed or has been presented with maliciously false information. (ii) United States In the United States, the tax authority may review tax returns for up to 3 years from the expiration date of the tax return. In the event that an omission or error is detected in the tax return of sales or cost of sales, the review can be extended for a period of up to 6 years. (iii) Mexico: In Mexico, the tax authority can review tax returns up to 5 years from the expiration date of the tax return. (iv) Spain: In Spain, the tax authority can review tax returns up to 4 years from the expiration date of the tax return. A subsidiary of the Company, SQM Iberian S.A., is being reviewed by the Spanish Tax Authority. This audit could involve adjustments to tax returns filed in Spain. (v) Belgium: In Belgium, the tax authority may review tax returns for up to 3 years from the expiration date of the tax return if no tax losses exist. In the event of detecting an omission or error in the tax return, the review can be extended for a period of up to 5 years. (vi) South Africa: In South Africa, the tax authority may review tax returns for up to 3 years from the expiration date of the tax return. In the event that an omission or error in the tax return is detected, the review can be extended for a period of up to 5 years.

The Company continues to monitor and evaluate the spread of the coronavirus and its impact on our operations, business, financial condition and results of operations. On February 25, 2022 SQM NA submitted to the Central District Court of California an appeal bond for US$ 60.1 million to guarantee the final settlement, in connection with the case reported in Note 20.1 (c).

Description of accounting policy for functional currency [text block]	3.2 F The Company’s consolidated financial statements are presented in United States dollars, without decimal places, which is the Company’s functional and presentation currency and is the currency of the main economic environment in which it operates. Consequently, the term foreign currency is defined as any currency other than the U.S. dollar.
Description of accounting policy for foreign currency translation [text block]	3.3 A (a) SQM group entities: The revenue, expenses, assets and liabilities of all entities that have a functional currency other than the presentation currency are converted to the presentation currency as follows: - Assets and liabilities are converted at the closing exchange rate prevailing on the reporting date. - Revenues and expenses of each profit or loss account are converted at monthly average exchange rates. - All resulting foreign currency translation gains and losses are recognized as a separate component in translation reserves. In consolidation, foreign currency differences arising from the translation of a net investment in foreign entities are recorded in shareholder’s equity (“foreign currency translation reserve”). At the date of disposal, such foreign currency translation differences are recognized in the statement of income as part of the gain or loss from the sale. The main exchange rates and UF used to translate monetary assets and liabilities, expressed in foreign currency at the end and average of each period in respect to U.S. dollars, are as follows: Closing exchange rates Average exchange rates Currencies As of December 31, 2021 As of December 31, As of December 31, 2021 As of December 31, ThUS$ ThUS$ ThUS$ ThUS$ Brazilian real 5.57 5.18 5.66 5.14 New Peruvian sol 3.99 3.62 4.04 3.60 Japanese yen 115.18 103.30 113.87 103.81 Euro 0.88 0.81 0.88 0.82 Mexican peso 20.54 19.93 20.90 19.97 Australian dollar 1.38 1.30 1.40 1.33 Pound Sterling 0.74 0.74 0.75 0.74 South African rand 15.94 14.61 15.88 14.88 Chilean peso 844.69 710.95 849.46 731.92 Chinese yuan 6.38 6.51 6.37 6.53 Indian rupee 74.42 73.30 75.40 73.65 Thai Baht 33.32 29.94 33.55 30.08 Turkish lira 13.28 7.36 13.54 7.70 UF (*) 36.69 40.89 36.48 39.73 (*) US$ per UF (b) Transactions and balances The Company’s non-monetary transactions in currencies other than the functional currency (Dollar) are translated to the respective functional currencies of Group entities at the exchange rate on the date of the transaction. Monetary assets and liabilities denominated in foreign currencies at the reporting date are retranslated to the functional currency at the exchange rate at that date. All differences are recorded in the statement of income except for all monetary items that provide an effective hedge for a net investment in a foreign operation. These items are recognized in other comprehensive income until disposal of the investment, when they are recognized in the statement of income. Charges and credits attributable to foreign currency translation differences on those hedge monetary items are also recognized in other comprehensive income. Non-monetary assets and liabilities that are measured at historical cost in a foreign currency are retranslated to the functional currency at the historical exchange rate of the transaction. Non-monetary items that are measured based on fair value in a foreign currency are translated using the exchange rate at the date on which the fair value is determined.
Description of accounting policy for cash flows [text block]	3.4 C Cash equivalents correspond to highly liquid short-term investments that are easily convertible into known amounts of cash and subject to insignificant risk of changes in their value and mature in less than three months from the date of acquisition of the instrument. For the purposes of the statement of cash flows, cash and cash equivalents comprise cash and cash equivalents as defined above. The statement of cash flows present cash transactions performed during the period, determined using the direct method.
Description of accounting policy for financial assets [text block]	3.5 F Management determines the classification of its financial assets at fair value (either through other comprehensive income, or through profit or loss), and at amortized cost. The classification depends on the business model of the entity to manage the financial assets and the contractual terms of the cash flows. In the initial recognition, the Company measures its financial assets at fair value more or less, in the case of a financial asset that is not accounted for at fair value through profit or loss, the transaction costs that are directly attributable to the acquisition of the financial asset on the date when the Company commits to the purchase or sale of an asset. In the case of account receivables and other accounts receivables, the transaction price at the initial recognition is measured. After initial recognition, the Company measures its financial assets according to the Company's business model for managing its financial assets and the contractual terms of its cash flows: (a) Financial instruments measured at amortized cost. Financial assets that meet the following conditions are included in this category (i) the business model that supports it aims to maintain the financial assets to obtain the contractual cash flows and the contractual conditions of the financial asset give place, on specified dates, to cash flows that are only payments of the principal and interest on the outstanding principal amount. The Company’s financial assets that meet these conditions are: (ii) cash equivalents; (iii) related party receivables; (iv) trade debtors; (v) other receivables. (b) Financial instruments at fair value. A financial asset should be measured at fair value through profit or loss or fair value through other comprehensive income, depending on the following: (i) "Fair Value Through Other Comprehensive Income": Assets held to collect contractual cash flows and to be sold, where the asset cash flows are only capital and interest payments, are measured at fair value through other comprehensive income. Changes in book values are through other comprehensive income, except for the recognition of impairment losses, interest income and exchange gains and losses, which are recognized in the income statement. When a financial asset is derecognized, the cumulative gain or loss previously recognized in other comprehensive income is reclassified from equity to the income statement. Interest income from these financial assets is included in financial income using the effective interest method. (ii) "Fair Value Through Profit and Loss": Assets that do not meet the amortized cost or "Fair Value Through Other Comprehensive Income" criteria are valued at "Fair Value Through Profit and Loss". (c) Financial equity assets at fair value through other comprehensive income. Equity instruments that are not classified as held for trading and which the Group has irrevocably chosen to recognize in this category. Amounts presented in other comprehensive income will not be subsequently transferred to profit or loss.
Description of accounting policy for impairment of financial assets [text block]	3.6 F The Company evaluates expected credit losses associated with its debt instruments carried at amortized cost and fair value through other comprehensive income. The impairment method used depends on whether there has been a significant increase in credit risk. The Company applies simplified approach to measure expected credit losses using the lifetime expected loss on all trade receivables. Expected credit losses are measured by grouping receivables by their shared credit risk characteristics and days overdue. The Company has concluded that the expected loss rates for trade receivables are a reasonable approximation of the loss rates for contract assets. Expected loss rates are based on sales payment profiles and historical credit losses within this period. Historical loss rates are adjusted to reflect current expectations and information regarding macroeconomic factors that affect the ability of customers to meet their commitments. Impairment losses from receivables and contract assets are shown as net impairment losses in the line “Impairment of financial assets and reversal of impairment losses,” see Note 21.7. The subsequent recovery of previously canceled amounts are credited to the same line.
Description of accounting policy for financial liabilities [text block]	3.7 F Management determines the classification of its financial liabilities at fair value or at amortized cost. The classification depends on the business model of the entity to manage the financial liabilities and the contractual terms of the cash flows. At the initial recognition, the Company measures its financial liabilities by their fair value more or less, in the case of a financial liability that is not accounted for at fair value through profit or loss, the transaction costs that are directly attributable to the acquisition of the financial liability. After initial recognition, the Company measures its financial liabilities at amortized cost unless the Company, at the initial moment, irrevocably designates the financial liability as measured at fair value through profit or loss. Financial liabilities measured at amortized cost are commercial accounts payable and other accounts payable and other financial liabilities. Amortized cost is based using the effective interest rate method. Amortized cost is calculated by considering any premium or discount on the acquisition and includes transaction costs that are an integral part of the effective interest rate. Financial liabilities are recorded as not current when they mature in more than 12 months and as current when they mature in less than 12 months.
Description of accounting policy for reclassification of financial instruments [text block]	3.8 R When the Company changes its business model for managing financial assets, it will reclassify all its financial assets affected by the new business model. Financial liabilities cannot be reclassified.
Description of accounting policy for derecognition of financial instruments [text block]	3.9 F The Company derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred; and the control of the financial assets has not been retained. The Company derecognizes a financial liability when its contractual obligations or a part of these are discharged, paid to the creditor or legally extinguished from the principle responsibility contained in the liability.
Description of accounting policy for derivative financial instruments and hedging [text block]	3.10 D Derivatives are recognized initially at fair value as of the date on which the derivatives contract is signed and, they are subsequently assessed at fair value. The method for recognizing the resulting gain or loss depends on whether the derivative has been designated as an accounting hedge instrument and, if so, it depends on the type of hedging, which may be as follows: a) Fair value hedge of assets and liabilities recognized (fair value hedges); b) Hedging of a single risk associated with a recognized asset or liability or a highly probable forecast transaction (cash flow hedge). At the beginning of the transaction, the Company documents the relationship that exists between hedging instruments and those items hedged, as well as their objectives for risk management purposes and the strategy to conduct different hedging operations. The Company also documents its evaluation both at the beginning and at the end of each period if the derivatives used in hedging transactions are highly effective to offset changes in the fair value or in cash flows of hedged items. The fair value of derivative instruments used for hedging purposes is shown in Note 12.3. Changes in the cash flow hedge reserve are classified as a non-current asset or liability if the remaining expiration period of the hedged item is more than 12 months, and as a current asset or liability if the remaining expiration period of the hedged item is less than 12 months. Derivatives that are not designated or do not qualify as hedging derivatives are classified as current assets or liabilities, and changes in the fair value are directly recognized through profit or loss. a) Fair value hedge Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded in profit or loss, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk. The gain or loss relating to the effective portion of interest rate swaps that hedge fixed rate borrowings is recognized in profit or loss within finance costs, together with changes in the fair value of the hedged fixed rate borrowings attributable to interest rate risk. The gain or loss relating to the ineffective portion is recognized in profit or loss within other income or other expenses. If the hedge no longer meets the criteria for hedge accounting, the adjustment to the carrying amount of a hedged item for which the effective interest method is used is amortized to profit or loss over the period to maturity using a recalculated effective interest rate. b) Cash flow hedges The effective portion of the gain or loss on the hedging instrument is initially recognized with a debit or credit to other comprehensive income, while any ineffective portion is immediately recognized with a debit or credit to income, as appropriate depending on the nature of the hedged risk. The amounts accumulated in net equity are carried over to results when the hedged items are settled or when these have an impact on results. When a hedging instrument no longer meets the criteria for hedge accounting, any cumulative deferred gain or loss and deferred costs of hedging in equity at that time remains in equity until the forecast transaction occurs. When the forecast transaction is no longer expected to occur, the cumulative gain or loss and deferred costs of hedging that were reported in equity are immediately reclassified to profit or loss.
Description of accounting policy for derivative financial instruments not considered as hedges [text block]	3.11 D Derivative financial instruments not considered as hedges are recognized at fair value with the effect in the results of the year. The Company has derivative financial instruments to hedge foreign currency risk exposure. The Company continually evaluates the existence of embedded derivatives in both its contracts and in its financial instruments. As of December 31, 2021, and 2020, the Company does not have any embedded derivatives.
Description of accounting policy for deferred acquisition costs arising from insurance contracts [text block]	3.12 D Acquisition costs from insurance contracts are classified as prepayments and correspond to insurance contracts in force, recognized using the straight-line method and on an accrual basis independent of payment date. These are recognized under other non-financial assets.
Description of accounting policy for leases [text block]	3.13 L (a) Right-of-use assets The Company recognizes right-of-use assets on the initial lease date (i.e., the date on which the underlying asset is available for use). Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, adjusted by any new measurement of the lease liability. The cost of right-of-use assets includes the amount of recognized lease liabilities, direct initial costs incurred and lease payments made on the start date or sooner, less the lease incentives received. Unless the Company is reasonably sure it will take ownership of the leased asset at the end of the lease period, the assets recognized through right-of-use are depreciated in a straight line during the shortest period of their estimated useful life and lease period. Right-of-use assets are subject to impairment. (b) Lease liabilities On the lease start date, the Company recognizes lease liabilities measured at present value of lease payments that will be made during the lease period. Lease payments include fixed payments (including payments that are essentially fixed), less incentives for lease receivables, variable lease payments that are dependent on an index or rate and amounts that are expected to be paid as guaranteed residual value. Lease payments also include the exercise price of a purchase option if the Company is reasonably sure it will exercise this and penalty payments for terminating a lease, if the lease period reflects that the Company will exercise the option to terminate. Variable lease payments that are not dependent on an index or rate are recognized as expenses in the period that produces the event or condition that triggers payment. When calculating the present value of lease payments, the Company uses the incremental borrowing rate on the initial lease date if the interest rate implicit in the lease cannot be determined easily. After the start date, the lease liability balance will increase to reflect the accumulation of interest and will diminish as lease payments are made. Furthermore, the book value of lease liabilities is remeasured in the event of an amendment, a change in the lease period, a change in the fixed lease payments in substance or a change in the assessment to buy the underlying asset. Payments made that affect lease liabilities are presented as part of the financing activities in the cash flow statement. (c) Short-term leases and low-value asset leases The Company applies the short-term lease recognition exemption to leases with a lease term of 12 months or less starting on the start date and that don’t have a purchase option. It also applies the low-value asset lease recognition exemptions to leases less than the limit specified in the respective accounting standard. Lease payments in short-term leases and low-value asset leases are recognized as lineal expenses during the lease term. (d) Significant judgments in the determination of the lease term for contracts with renewal options. The Company determines the lease term as the non-cancellable period of the lease, together with periods covered by an option to extend the lease if it is reasonably certain that this will be exercised, or any period covered by an option to terminate the lease, if it is reasonably certain that this will not be exercised. The Company has the option, under some of its leases, to lease assets for additional terms. The Company applies its judgment when assessing whether it is reasonably certain that it will exercise the option to renovate. In other words, it considers all the relevant factors that create an economic incentive for it to exercise the option to renovate. After the start date, the Company reevaluates the lease term if there is a significant event or change in the circumstances that are under its control and affect its capacity to exercise (or not exercise) the option to renovate.
Description of accounting policy for trade and other receivables [text block]	3.14 I The method used to determine the cost of inventories is the weighted average monthly cost of warehouse storage. In determining production costs for own products, the company includes the costs of labor, raw materials, materials and supplies used in production, depreciation and maintenance of the goods that participate in the production process, the costs of product movement necessary to maintain stock on location and in the condition in which they are found, and also includes the indirect costs of each task such as laboratories, process and planning areas, and personnel expenses related to production, among others. For finished and in-process products, the company has four types of provisions, which are reviewed quarterly: (a) Provision associated with the lower value of stock: The provision is directly identified with the product that generates it and involves three types: (i) provision of lower realizable value, which corresponds to the difference between the inventory cost of intermediary or finished products, and the sale price minus the necessary costs to bring them to the same conditions and location as the product with which they are compared; (ii) provision for future uncertain use that corresponds to the value of those products in process that are likely not going to be used in sales based on the company’s long-term plans; (iii) reprocessing costs of products that are unfeasible for sale due to current specifications. (b) Provision associated with physical differences in inventory: A provision is made for differences that exceed the tolerance considered in the respective inventory process (physical and annual inventories are taken for the productive units in Chile and the port of Tocopilla; the business subsidiaries depend on the last zero ground obtained, but in general it is at least once a year), these differences are recognized immediately. (c) Potential errors in the determination of stock: The company has an algorithm that is reviewed at least once a year and corresponds to diverse percentages assigned to each inventory based on the product, location, complexity involved in the associated measurement, rotation and control mechanisms. (d) Provisions undertaken by business subsidiaries: these are historical percentages that are adjusted as zero ground is attained based on normal inventory management. Inventories of raw materials, materials and supplies for production are recorded at acquisition cost. Cyclical inventories are performed in warehouses, as well as general inventories every three years. Differences are recognized at the moment they are detected. The company has a provision that makes quarterly calculations from percentages associated with each type of material (classification by warehouse and rotation), these percentages use the lower value resulting from deterioration or obsolescence as well as potential losses. This provision is reviewed at least annually, and considers the historical profit and loss obtained in the inventory processes.
Description of accounting policy for transactions with non-controlling interests [text block]	3.15 N Non-controlling interests are recorded in the consolidated statement of financial position within equity but separate from equity attributable to the owners of the Parent.
Description of accounting policy for transactions with related parties [text block]	3.16 R Transactions between the Company and its subsidiaries are part of the Company’s normal operations within its scope of business activities. Conditions for such transactions are those normally effective for those types of operations with regard to terms and market prices. The maturity conditions vary according to the originating transaction.
Description of accounting policy for property, plant and equipment [text block]	3.17 P Property, plant and equipment are stated at acquisition cost, net of the related accumulated depreciation, amortization and impairment losses that they might have experienced. In addition to the price paid for the acquisition of tangible property, plant and equipment, the Company has considered the following concepts as part of the acquisition cost, as applicable: (a) Accrued interest expenses during the construction period that are directly attributable to the acquisition, construction or production of qualifying assets, which are those that require a substantial period prior to being ready for use. The interest rate used is that related to the project’s specific financing or, should this not exist, the average financing rate of the investor company. (b) The future costs that the Company will have to experience, related to the closure of its facilities at the end of their useful life, are included at the present value of disbursements expected to be required to settle the and its subsequent variation is recorded directly in results. Having initially recognized provisions for closure and refurbishment, the corresponding cost is capitalized as an asset in “Property, plant and equipment” and amortized in line with the amortization criteria for the associated assets. Construction-in-progress is transferred to property, plant and equipment in operation once the assets are available for use and the related depreciation and amortization begins on that date. Extension, modernization or improvement costs that represent an increase in productivity, ability or efficiency or an extension of the useful lives of property, plant and equipment are capitalized as a higher cost of the related assets. All the remaining maintenance, preservation and repair expenses are charged to expense as they are incurred. The replacement of assets, which increase the asset’s useful life or its economic capacity, are recorded as a higher value of property, plant and equipment with the related derecognition of replaced or renewed elements. Gains or losses which are generated from the sale or disposal of property, plant and equipment are recognized as income (or loss) in the period and calculated as the difference between the asset’s sales value and its net carrying value. Costs derived from the daily maintenance of property, plant and equipment are recognized when incurred.
Description of accounting policy for depreciation of property, plant and equipment [Text Block]	3.18 D Property, plant and equipment are depreciated through the straight-line distribution of cost over the estimated technical useful life of the asset, which is the period in which the Company expects to use the asset. When components of one item of property, plant and equipment have different useful lives, they are recorded as separate assets and depreciated over their expected useful lives. Fixed assets located in the Salar de Atacama consider useful life to be the lesser value between the technical useful life and the years remaining until 2030. In the case of certain mobile equipment, depreciation is performed depending on the hours of operation. The useful lives used for the depreciation and amortization of assets included in property, plant and equipment in years are presented below: Classes of property, plant and equipment Minimum life or Maximum life or Life or average rate Mining assets 3 10 7 Energy generating assets 3 16 9 Buildings 3 25 14 Supplies and accessories 2 10 7 Office equipment 5 10 9 Transport equipment 5 9 7 Network and communication equipment 4 10 5 IT equipment 4 11 7 Machinery, plant and equipment 2 25 13 Other fixed assets 3 20 10
Description of accounting policy for goodwill [text block]	3.19 G Goodwill acquired represents the excess in acquisition cost on the fair value of the Company's ownership of the net identifiable assets of the subsidiary on the acquisition date. Goodwill acquired related to the acquisition of subsidiaries is included in the line item goodwill, which is subject to impairment tests annually or more frequently if events or changes in circumstances indicate that it might be impaired and is stated at cost less accumulated impairment losses. Gains and losses related to the sale of an entity include the carrying value of goodwill related to the entity sold. This intangible asset is assigned to cash-generating units with the purpose of testing impairment losses. It is allocated based on cash-generating units expected to obtain benefits from the business combination from which the aforementioned goodwill acquired arose.
Description of accounting policy for intangible assets other than goodwill [text block]	3.20 I Intangible assets other than goodwill mainly relate to water rights, emission rights, commercial brands, costs for rights of way for electricity lines, license costs and the development of computer software and mining property and concession rights, client portfolio and commercial agent. (a) Water rights Water rights acquired by the Company relate to water from natural sources and are recorded at acquisition cost. The Company separates water rights into: i) Finite rights with amortization using the straight-line method, and ii) Indefinite rights, which are not amortized, given that these assets represent rights granted in perpetuity to the Company, which are subject to an annual impairment assessment. (b) Rights of way for electric lines As required for the operation of industrial plants, the Company has paid rights of way in order to install wires for the different electric lines on third party land. These rights are presented under intangible asset. Amounts paid are capitalized at the date of the agreement and amortized in the statement of income, according to the life of the right of way. (c) Computer software Licenses for IT programs acquired are capitalized based on their acquisition and customization costs. These costs are amortized over their estimated useful lives. Expenses related to the development or maintenance of IT programs are recognized as an expense as and when incurred. Costs directly related to the production of unique and identifiable IT programs controlled by the Group, and which will probably generate economic benefits that are higher than its costs during more than a year, are recognized as intangible assets. Direct costs include the expenses of employees who develop information technology software and general expenses in accordance with corporate charges received. The costs of development for IT programs are recognized as assets are amortized over their estimated useful lives. (d) Mining property and concession rights The Company holds mining property and concession rights from the Chilean and Western Australian Governments. Property rights from the State of Chile are usually obtained at no initial cost (other than the payment of mining patents and minor recording expenses) and once the rights on these concessions have been obtained, they are retained by the Company while annual patents are paid. Such patents, which are paid annually, are recorded as prepaid assets and amortized over the following twelve months. Amounts attributable to mining concessions acquired from third parties that are not from the Chilean Government are recorded at acquisition cost within intangible assets. (e) Estimated useful lives or amortization rates used for finite identifiable intangible assets The finite useful life of mining properties is calculated using the productive unit method, except for the mining properties owned by Corfo, which have been leased to the Company and grant it the right to exclusively exploit them until December 31, 2030. The estimated useful life for software which they are amortized corresponds to the periods defined by the contracts or rights from which they originate. f) Minimum and maximum amortization lives or rates of intangible assets: Estimated useful life or amortization rate Minimum Life or Maximum Life or Water rights 5 years Indefinite Rights of way Indefinite Indefinite Corfo Mining properties (1) 9 years 9 years Mining rights Unit-production method Intellectual property 9 years 9 years IT programs 2 years 8 years (1) Mining properties owned by CORFO and leased to the Company, which grant it the exclusive right to exploit them until December 31, 2030.
Description of accounting policy for research and development expense [text block]	3.21 R Research and development expenses are charged to profit or loss in the period in which the expenditure was incurred.
Description of accounting policy for exploration and evaluation expenses [text block]	3.22 E The Company holds mining concessions for exploration and exploitation of ore, the Company gives the following treatment to expenses associated with exploration and assessment of these resources: Once the rights have been obtained, the Company records the disbursements directly associated with the exploration and evaluation of the deposit in execution as property, plant and equipment (construction in progress) at its cost. These disbursements include the following items: geological surveys, drilling, borehole extraction and sampling, activities related to the technical assessment and commercial viability of the extraction, and in general, any disbursement directly related to specific projects where the objective is to find ore resources. If the technical studies determine that the ore grade is not economically viable, the asset is directly charged to profit and loss. If determined otherwise, the asset described above is associated with the extractable ore tonnage which is amortized as it is used. (a) Limestone and metallic exploration These assets are included in Other Non-Current Non-Financial Assets, and the portion related to the area to be exploited in the year are reclassified to Current Inventory, if applicable. Costs related to metal exploration are charged to profit or loss in the period in which they are recognized if the project assessed doesn't qualify for consideration as advanced exploration otherwise, these are amortized during the development stage. (b) Exploration in Salar de Atacama Exploration expenses in Salar de Atacama are included in non-current assets under Property, Plant and Equipment and are mainly bore holes that can also be used to exploit the deposit or monitoring, which are amortized over 9 years. (c) Exploration and evaluation at the Mt. Holland Project Mount Holland exploration and evaluation expenditure is included in Property, plant and equipment, specifically in Construction in Progress. See Note 1. 8.
Description of accounting policy for impairment of non-financial assets [text block]	3.23 I Assets subject to depreciation and amortization are also subject to impairment testing, provided that an event or change in the circumstances indicates that the amounts in the accounting records may not be recoverable, an impairment loss is recognized for the excess of the book value of the asset over its recoverable amount. For assets other than goodwill, the Group annually assesses whether there is any indication that a previously recognized impairment loss may no longer exist or may have decreased. Should such indications exist, the recoverable amount is estimated. The recoverable amount of an asset is the higher between the fair value of an asset or cash generating unit less costs of sales and its value in use, and is determined for an individual asset unless the asset does not generate any cash inflows that are clearly independent from other assets or groups of assets. In evaluating value in use, estimated future cash flows are discounted using a pre-tax discount rate that reflects current market assessment, the value of money over time and the specific asset risks. Impairment losses from continuing operations are recognized with a debit to profit or loss in the categories of expenses associated with the impaired asset function. For assets other than goodwill, a previously recognized impairment loss is only reversed if there have been changes in the estimates used to determine the asset’s recoverable amount since the last time an impairment loss was recognized. If this is the case, the carrying value of the asset is increased to its recoverable amount. This increased amount cannot exceed the carrying value that would have been determined, net of depreciation, if an asset impairment loss had not been recognized in prior years. This reversal is recognized with a credit to profit or loss. Assets with indefinite lives are assessed for impairment annually. The current value of future cash flows generated by these assets has been estimated given the variation in sales volumes, market prices and costs, discounted with a WACC rate. For December 31, 2021, the WACC rate was 9.90%.
Description of accounting policy for dividends [text block]	3.24 M As required by Chilean law and regulations, our dividend policy is decided upon from time to time by our Board of Directors and is announced at the Annual Ordinary Shareholders’ Meeting, which is generally held in April of each year. Shareholder approval of the dividend policy is not required. However, each year the Board must submit the declaration of the final dividend or dividends in respect of the preceding year, consistent with the then-established dividend policy, to the Annual Ordinary Shareholders’ Meeting for approval. As required by the Chilean Companies Act, unless otherwise decided by unanimous vote of the holders of issued shares, we must distribute a cash dividend in an amount equal to at least 30% of our consolidated net income for that year (determined in accordance with CMF regulations), unless and to the extent the Company has a deficit in retained earnings. (See Note 19.5).
Description of accounting policy for earnings per share [text block]	3.25 E The basic earnings per share amounts are calculated by dividing the profit for the year attributable to the ordinary owners of the parent by the weighted average number of ordinary shares outstanding during the year. The Company has not conducted any type of operation of potential dilutive effect that would entail the disclosure of diluted earnings per share.
Description of accounting policy for provisions [text block]	3.26 O Provisions are recognized when: · The Company has a present, legal or constructive obligation as the result of a past event. · It is more likely than not that certain resources must be used, to settle the obligation. · A reliable estimate can be made of the amount of the obligation. In the event that the provision or a portion of it is reimbursed, the reimbursement is recognized as a separate asset solely if there is certainty of income. In the consolidated statement of income, the expense for any provision is presented net of any reimbursement. Should the effect of the value of money over time be significant, provisions are discounted using a discount rate before tax that reflects the liability’s specific risks. When a discount rate is used, the increase in the provision over time is recognized as a finance cost. The Company’s policy is to maintain provisions to cover risks and expenses based on a better estimate to deal with possible or certain and quantifiable responsibilities from current litigation, compensations or obligations, pending expenses for which the amount has not yet been determined, collaterals and other similar guarantees for which the Company is responsible. These are recorded at the time the responsibility or the obligation that determines the compensation or payment is generated.
Description of accounting policy for employee benefits [text block]	3.27 O Obligations towards the Company’s employees comply with the provisions of the collective bargaining agreements in force, which are formalized through collective employment agreements and individual employment contracts, except for the United States, which is regulated in accordance with employment plans in force up to 2002. (See more details in Note 17.4). These obligations are valued using actuarial calculations, according to the projected unit credit method which considers such assumptions as the mortality rate, employee turnover, interest rates, retirement dates, effects related to increases in employees’ salaries, as well as the effects on variations in services derived from variations in the inflation rate. Actuarial gains and losses that may be generated by variations in defined, pre-established obligations are directly recorded in “Other Comprehensive Income”. Actuarial losses and gains have their origin in deviations between the estimate and the actual behavior of actuarial assumptions or in the reformulation of established actuarial assumptions. The Company’s subsidiary SQM North America has established pension plans for its retired employees that are calculated by measuring the projected obligation using a net salary progressive rate net of adjustments for inflation, mortality and turnover assumptions, deducting the resulting amounts at present value.

Description of accounting policy for share-based payment transactions [text block]	3.28 C Compensation plans implemented through benefits provided in share-based payments settled in cash are recognized in the financial statements at their fair value, in accordance with IFRS 2.

Description of accounting policy for recognition of revenue [text block]	3.29 R Revenue includes the fair value of considerations received or receivable for the sale of goods and services during the performance of the Company's activities. Revenue is presented net of value added tax, estimated returns, rebates and discounts and after the elimination of sales among subsidiaries. Revenues are recognized when the specific conditions for each income stream are met, as follows: (a) Sale of goods The sale of goods is recognized when the Company has delivered products to the customer, and there is no obligation pending compliance that could affect the acceptance of products by the customer. The delivery does not occur until products have been shipped to the customer or confirmed as received by the customer, and the related risks of obsolescence and loss have been transferred to the customer and the customer has accepted the products in accordance with the conditions established in the sale, when the acceptance period has ended, or when there is objective evidence that those criteria required for acceptance have been met. Sales are recognized in consideration of the price set in the sales agreement, net of volume discounts and estimated returns at the date of the sale. Volume discounts are evaluated in consideration of annual foreseen purchases and in accordance with the criteria defined in agreements. (b) Sale of services Revenue associated with the rendering of services is recognized considering the degree of completion of the service as of the date of presentation of the consolidated classified statement of financial position, provided that the result from the transaction can be estimated reliably. (c) Income from dividends Income from dividends is recognized when the right to receive the payment is established.
Description of accounting policy for finance income and costs [text block]	3.30 F Finance income is mainly composed of interest income from financial instruments such as term deposits and mutual fund deposits. Interest income is recognized in profit or loss at amortized cost, using the effective interest rate method. Finance costs are mainly composed of interest on bank borrowing expenses, interest on bonds issued and interest capitalized for borrowing costs for the acquisition, construction or production or qualifying assets. Borrowing costs and bonds issued are also recognized in profit or loss using the effective interest rate method.
Description of accounting policy for income tax and deferred taxes [Text Block]	3.31 C Corporate income tax for the year is determined as the sum of current and deferred income taxes from the different consolidated companies. Current taxes are based on the application of the various types of taxes attributable to taxable income for the period. The Company periodically assesses the positions taken in the determination of taxes with respect to situations in which the applicable tax regulation is subject to interpretation and considers whether it is probable that a tax authority will accept an uncertain tax treatment. The Company measures its tax balances based on the most likely Differences between the book value of assets and liabilities and their tax basis generate the balance of deferred tax assets or liabilities, which are calculated using the tax rates expected to be applicable when the assets and liabilities are realized. In conformity with current tax regulations, the provision for corporate income tax and taxes on mining activity is recognized on an accrual basis, presenting the net balances of accumulated monthly tax provisional payments for the fiscal period and associated credits. The balances of these accounts are presented in current income taxes recoverable or current taxes payable, as applicable. Income tax and variations in deferred tax assets or liabilities that are not the result of business combinations are recorded in income or equity, considering the origin of the gains or losses which have generated them. At each reporting period, the carrying amount of deferred tax assets is reviewed and recognized only if it is probable that future taxable amounts will be available to allow the recovery of all or a portion of the deferred tax assets. With respect to deductible temporary differences associated with investments in subsidiaries, associated companies and interest in joint ventures, deferred tax assets are recognized solely provided that it is more likely than not that the temporary differences will be reversed in the near future and that there will be taxable income with which they may be used. The deferred taxes related to items directly recognized in equity is registered with effect on other comprehensive income and not with effect on income. Deferred tax assets and liabilities are offset if there is a legally receivable right of offsetting tax assets against tax liabilities and the deferred tax is related to the same tax entity and authority. The recognized deferred tax assets refer to the amount of income tax to recover in future periods, related to: a) deductible temporary differences; b) compensation for losses obtained in prior periods, which have not yet been subject to tax deduction; and c) compensation for unused credits from prior periods. The Company recognizes deferred tax assets when it has the certainty that they can be offset with tax income from subsequent periods, unused tax losses or credits to date, but only when this availability of future tax income is probable and can be used for offsetting these unused tax losses or credits. The recognized deferred tax liabilities refer to the amount of income tax to pay in a future period, related to taxable temporary differences. The Company does not recognize deferred tax liabilities in all cases of taxable temporary differences associated with investments in subsidiaries, branches and associates, or with joint ventures, because based on the standard, the two following conditions both apply: (i) the parent company, investor or shareholder is capable of controlling the moment of the reversal of temporary differences; and (ii) it is probable that the temporary difference will not be reversed in the foreseeable future. Moreover, the Company does not recognize deferred tax assets for all the deductible temporary differences that originate from investments in subsidiaries, branches and associates, or from joint ventures, because it is unlikely that they meet the following requirements: (i) temporary differences are reversed in the foreseeable future; and (ii) there is taxable profit available against which temporary differences can be used.
Description of accounting policy for segment reporting [text block]	3.32 O IFRS 8 requires that companies adopt a management approach to disclose information on the operations generated by its operating segments. In general, this is the information that management uses internally for the evaluation of segment performance and making the decision on how to allocate resources for this purpose. An operating segment is a group of assets and operations responsible for providing products or services subject to risks and performance that are different from those of other business segments. A geographical segment is responsible for providing products or services in a given economic environment subject to risks and performance that are different from those of other segments operating in other economic environments. Allocation of assets and liabilities, to each segment is not possible given that these are associated with more than one segment, except for depreciation, amortization and impairment of assets, which are directly allocated in accordance with the criteria established in the costing process for product inventories to the corresponding segments.
Description of accounting policy for responsibility for information and estimates made [Text Block]	3.33 P Management is responsible for the information contained in these consolidated annual accounts, which expressly indicate that all the principles and criteria included in IFRS, as issued by the IASB, have been applied in full. In preparing the consolidated financial statements of the Company and its subsidiaries, management has made significant judgments and estimates to quantify certain assets, liabilities, revenues, expenses and commitments included therein. Basically, these estimates refer to: · Estimated useful lives are determined based on current facts and past experience and take into consideration the expected physical life of the asset, the potential for technological obsolescence, and regulations. (See Notes 3.20, 14 and 15). · Impairment losses of certain assets - Goodwill and intangible assets that have an indefinite useful life are not amortized and are assessed for impairment on an annual basis, or more frequently if the events or changes in circumstances indicate that these may have deteriorated Other assets, including property, plant and equipment, exploration assets, goodwill and intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amounts exceed their recoverable amounts. If an impairment assessment is required, the assessment of fair value or value in use often requires estimates and assumptions such as discount rates, exchange rates, commodity prices, future capital requirements and future operating performance. Changes in such estimates could impact the recoverable values of these assets. Estimates are reviewed regularly by management (See Notes 14 and 15). · Assumptions used in calculating the actuarial amount of pension-related and severance indemnity payment benefit commitments (See Note 17). · Contingencies – The amount recognized as a provision, including legal, contractual, constructive and other exposures or obligations, is the best estimate of the consideration required to settle the related liability, including any related interest charges, considering the risks and uncertainties surrounding the obligation. In addition, contingencies will only be resolved when one or more future events occur or fail to occur. Therefore, the assessment of contingencies inherently involves the exercise of significant judgment and estimates of the outcome of future events. The Company assesses its liabilities and contingencies based upon the best information available, relevant tax laws and other appropriate requirements (See Note 20). If the Company is unable to rationally estimate the obligation or concluded no loss is probable but it is reasonably possible that a loss may be incurred, no provision is recorded but disclosed in the notes to the consolidated financial statements. · Volume determination for certain in-process and finished products is based on topographical measurements and technical studies that cover the different variables (density for bulk inventories and density and porosity for the remaining stock, among others), and related allowance. · Estimates for obsolescence provisions to ensure that the carrying value of inventory is not in excess of the net realizable Inventory valuation. (See Note 10). Even though these estimates have been made on the basis of the best information available on the date of preparation of these consolidated financial statements, certain events may occur in the future and oblige their amendment (upwards or downwards) over the next few years, which would be made prospectively.
