Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company	The Company Tronox Holdings plc (referred to herein as "Tronox", the "Company", "we", "us", or "our") operates titanium-bearing mineral sand mines and beneficiation operations in Australia and South Africa to produce feedstock materials that can be processed into TiO 2 for pigment, high purity titanium chemicals, including titanium tetrachloride, and Ultrafine© titanium dioxide used in certain specialty applications. Our strategy is to be vertically integrated and produce enough feedstock materials to be as self-sufficient as possible in the production of TiO 2 at our 9 pigment facilities located in the United States, Australia, Brazil, UK, France, the Netherlands, China and the Kingdom of Saudi Arabia (“KSA”). We believe that vertical integration is the best way to achieve our ultimate goal of delivering low cost, high-quality pigment to our coatings and other TiO 2 customers throughout the world. The mining, beneficiation and smelting of titanium bearing mineral sands creates meaningful quantities of zircon, pig iron and the rare-earth bearing mineral, monazite, which we also supply to customers around the world. We are a public limited company listed on the New York Stock Exchange and are registered under the laws of England and Wales. Basis of Presentation We are considered a domestic company in the United Kingdom and, as such, are required to comply with filing requirements in the United Kingdom. Additionally, we are not considered a “foreign private issuer” in the U.S.; therefore, we are required to comply with the reporting and other requirements imposed by the U.S. securities law on U.S. domestic issuers, which, among other things, requires reporting under accounting principles generally accepted in the United States of America (“U.S. GAAP”). The consolidated financial statements included in this Form 10-K are prepared in conformity with U.S. GAAP. Our consolidated financial statements include the accounts of all majority-owned subsidiary companies. All intercompany balances and transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the manner and presentation in the current period. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. It is at least reasonably possible that the effect on the financial statements of a change in estimate due to one or more future confirming events could have a material effect on the financial statements.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Foreign Currency The U.S. dollar is our reporting currency for our consolidated financial statements in U.S. GAAP. We determine the functional currency of each subsidiary based on a number of factors, including the predominant currency for revenues, expenditures and borrowings. Adjustments from the remeasurement of non-functional currency monetary assets and liabilities are recorded in “Other (expense) income, net” in the Consolidated Statements of Income. When a subsidiary’s functional currency is not the U.S. dollar, translation adjustments resulting from translating the functional currency financial statements into U.S. dollar equivalents are recorded in “Accumulated other comprehensive loss” in the Consolidated Balance Sheets. Translation adjustments on intercompany foreign currency receivables and payables that are not expected to be settled in the foreseeable future are reported in the same manner as translation adjustments. Revenue Recognition We recognize revenue at a point in time when the customer obtains control of the promised products. For most transactions this occurs when products are shipped from our manufacturing facilities or at a later point when control of the products transfers to the customer at a specified destination or time. All amounts billed to a customer in a sales transaction related to shipping and handling represent revenues earned and are reported as “Net sales” in the Consolidated Statements of Income. Accruals are made for sales returns, rebates and other allowances, which are recorded in “Net sales” in the Consolidated Statements of Income and are based on our historical experience and current business conditions. Additionally, we have elected the practical expedient to exclude sales taxes and similar taxes that we collect from customers on behalf of government authorities from the revenue transaction price. See Note 3. Cost of Goods Sold Cost of goods sold includes costs for purchasing, receiving, manufacturing, and distributing products, including raw materials, energy, labor, depreciation, depletion, shipping and handling, freight, warehousing, and other production costs. Research and Development Research and development costs, included in “Selling, general and administrative expenses” in the Consolidated Statements of Income comprised of salaries, building costs, utilities, administrative expenses, third party research, and allocations of corporate costs, were $12 million, $13 million, and $12 million during 2022, 2021, and 2020, respectively, and were expensed as incurred. Selling, General and Administrative Expenses Selling, general and administrative expenses include costs related to marketing, research and development, agent commissions, and legal and administrative functions such as corporate management, human resources, information technology, investor relations, accounting, treasury, and tax compliance. Income Taxes We use the asset and liability method of accounting for income taxes. The estimation of the amounts of income taxes involves the interpretation of complex tax laws and regulations and how foreign taxes affect domestic taxes, as well as the analysis of the realizability of deferred tax assets, tax audit findings, and uncertain tax positions. Deferred tax assets and liabilities are determined based on temporary differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. A valuation allowance is provided against a deferred tax asset when it is more likely than not that all or some portion of the deferred tax asset will not be realized. We periodically assess the likelihood that we will be able to recover our deferred tax assets and reflect any changes in our estimates in the valuation allowance, with a corresponding adjustment to earnings or other comprehensive income (loss), as appropriate. All available positive and negative evidence is weighted to determine whether a valuation allowance should be recorded. The amount of income taxes we pay is subject to ongoing audits by federal, state, and foreign tax authorities, which may result in proposed assessments. Our estimate of the potential outcome for any uncertain tax issue is highly judgmental. We assess our income tax positions, and record tax benefits for all years subject to examination based upon our evaluation of the facts, circumstances, and information available at the reporting date. For those tax positions for which it is more likely than not that a tax benefit will be sustained, we record the amount that has a greater than 50% likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. Interest and penalties are accrued as part of tax expense, where applicable. If we do not believe that it is more likely than not that a tax benefit will be sustained, no tax benefit is recognized. See Note 5. Earnings per Share Basic and diluted earnings per share are calculated using the two-class method. Under the two-class method, earnings used to determine basic earnings per share are reduced by an amount allocated to participating securities. Participating securities include restricted shares issued under the Tronox Management Equity Incentive Plan (the “MEIP”) (see Note 20), which contains non-forfeitable dividend rights. Our unexercised options and unvested restricted share units do not contain non-forfeitable rights to dividends and, as such, are not considered in the calculation of basic earnings per share. Our unvested restricted shares do not have a contractual obligation to share in losses; therefore, when we record a net loss, none of the loss is allocated to participating securities. Consequently, in periods of net loss, the two-class method does not have an effect on basic loss per share. Diluted earnings per share is calculated by dividing net earnings allocable to ordinary shares by the weighted-average number of ordinary shares outstanding for the period, as adjusted for the potential dilutive effect of non-participating restricted share units and options. The options are included in the calculation of diluted earnings per ordinary share utilizing the treasury stock method. See Note 6. Fair Value Measurement We measure fair value on a recurring basis utilizing valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs, to the extent possible, and consider counterparty credit risk in our assessment of fair value. The fair value hierarchy is as follows: • Level 1 – Quoted prices in active markets for identical assets and liabilities; • Level 2 – Quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active or other inputs that are observable or can be corroborated by observable market data; and, • Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities See Note 15. Cash and Cash Equivalents We consider all investments with original maturities of three months or less to be cash equivalents. We maintain cash and cash equivalents in bank deposit and money market accounts that may exceed federally insured limits. The financial institutions where our cash and cash equivalents are held are generally highly rated and geographically dispersed, and we have a policy to limit the amount of credit exposure with any one institution. We have not experienced any losses in such accounts and believe we are not exposed to significant credit risk. At December 31, 2022, we had restricted cash of less than $1 million which was in Australia related to outstanding performance bonds. At December 31, 2021, we had restricted cash of $4 million comprised of $3 million in Australia related to outstanding performance bonds and $1 million in Saudi Arabia related to vendor supply agreement guarantees. Accounts Receivable, net of allowance for credit losses We perform credit evaluations of our customers, and take actions deemed appropriate to mitigate credit risk. Only in certain specific occasions do we require collateral in the form of bank or parent company guarantees or guarantee payments. We maintain allowances for potential credit losses based on specific customer review and current financial conditions. Inventories, net Pigment inventories are stated at the lower of actual cost and net realizable value, net of allowances for obsolete and slow-moving inventory. The cost of inventories is determined using the first-in, first-out method. Carrying values include material costs, labor, and associated indirect manufacturing expenses. Costs for materials and supplies, excluding titanium ore, are determined by average cost to acquire. Feedstock and co-products inventories including titanium ore are stated at the lower of the weighted-average cost of production or market. Inventory costs include those costs directly attributable to products, including all manufacturing overhead but excluding distribution costs. Raw materials are carried at actual cost. We review the cost of our inventory in comparison to its net realizable value. We also periodically review our inventory for obsolescence. In either case, we record any write-down equal to the difference between the cost of inventory and its estimated net realizable value based on assumptions about alternative uses, market conditions and other factors. Inventories expected to be sold or consumed within twelve months after the balance sheet date are classified as current assets and all other inventories are classified as non-current assets. See Note 8. Long Lived Assets Property, plant and equipment, net is stated at cost less accumulated depreciation, and is depreciated over its estimated useful life using the straight-line method as follows: Land improvements 10 — 20 years Buildings 10 — 40 years Machinery and equipment 3 — 25 years Furniture and fixtures 10 years Maintenance and repairs are expensed as incurred, except for costs of replacements or renewals that improve or extend the lives of existing properties, which are capitalized. Upon retirement or sale, the cost and related accumulated depreciation are removed from the respective account, and any resulting gain or loss is included in “Cost of goods sold” or “Selling, general, and administrative expenses” in the Consolidated Statements of Income. See Note 9. We capitalize costs associated with our asset retirement obligations which are generally included in machinery and equipment. See Note 17. We capitalize interest costs on major projects that require an extended period of time to complete. See Note 13. Mineral property acquisition costs are capitalized as tangible assets when management determines that probable future benefits consisting of a contribution to future cash inflows have been identified and adequate financial resources are available or are expected to be available as required to meet the terms of property acquisition and anticipated exploration and development expenditures. Mineral leaseholds are depleted over their useful lives as determined under the units of production method. Mineral property exploration costs are expensed as incurred. When it has been determined that a mineral property can be economically developed as a result of establishing proven and probable reserves, the costs incurred to develop such property through the commencement of production are capitalized. See Note 10. Intangible assets are stated at cost less accumulated amortization and are amortized on a straight-line basis over their estimated useful lives, which generally range from 3 to 20 years. See Note 11. We evaluate the recoverability of the carrying value of long-lived assets that are held and used whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Under such circumstances, we assess whether the projected undiscounted cash flows of our long-lived assets are sufficient to recover the carrying amount of the asset group being assessed. If the undiscounted projected cash flows are not sufficient, we calculate the impairment amount by discounting the projected cash flows using our weighted-average cost of capital. For assets that satisfy the criteria to be classified as held for sale, an impairment loss, if any, is recognized to the extent the carrying amount exceeds fair value, less cost to sell. The amount of the impairment of long-lived assets is written off against earnings in the period in which the impairment is determined. Leases We determine if a contract is or contains a lease at inception of the contract. Our leases are primarily operating leases. Leased assets primarily include office buildings, rail cars and motor vehicles, forklifts, and other machinery and equipment. Our leases primarily have fixed lease payments, with real estate leases typically requiring additional payments for real estate taxes and occupancy-related costs. Certain of our leases also have variable lease payments. Variable lease payments that depend on an index or a rate (such as the Consumer Price Index) are included in our initial measurement of the lease right of use assets and lease liabilities. Variable lease payments that are not index or rate based (such as variable payments based on our performance or use of the leased assets) are recorded as expenses when incurred and excluded from the measurement of right of use assets and lease liabilities. Our leases typically have initial lease terms ranging from 1 to 25 years. Some of our lease agreements include options to renew, extend or early terminate the leases. Lease term is the non-cancellable period of a lease, adjusted by the period covered by an option to extend or terminate the lease if we are reasonably certain to exercise (or not exercise) that option. Our operating leases typically do not contain purchase options we expect to exercise, residual value guarantees or other material covenants. Operating leases are recorded under “Lease right of use assets”, “Short-term lease liabilities”, and “Long-term lease liabilities” on the Consolidated Balance Sheets. Finance leases are recorded under “Property, plant and equipment net”, “Long-term debt due within one year”, and “ Long-term debt Long-term Debt Long-term debt is stated net of unamortized original issue premium or discount. Premiums or discounts are amortized using the effective interest method with amortization expense recorded in “Interest and debt expense, net” in the Consolidated Statements of Income. Deferred debt issuance costs related to a recognized debt liability are presented in the Consolidated Balance Sheets as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts and are amortized using the effective interest method with amortization expense recorded in “Interest and debt expense, net” in the Consolidated Statements of Income. See Note 13. Asset Retirement Obligations Asset retirement obligations are recorded at their estimated fair value, and accretion expense is recognized over time as the discounted liability is accreted to its expected settlement value. Fair value is measured using expected future cash outflows discounted at our credit-adjusted risk-free interest rate, which are considered Level 3 inputs. We classify accretion expense related to asset retirement obligations as a production cost, which is included in “Cost of goods sold” in the Consolidated Statements of Income. See Note 17. Environmental Remediation and Other Contingencies We record an undiscounted liability when any of the following occur: 1) a claim or assessment has been asserted, 2) a litigation has commenced, or 3) based on available information, it is probable that a claim or an assessment will be asserted or a litigation will commence; and in addition, the outcome is expected to be unfavorable to us and the associated costs can be reasonably estimated. See Note 18. Self-Insurance We are self-insured for certain levels of general and vehicle liability, property, workers’ compensation and health care coverage. The cost of these self-insurance programs is accrued based upon estimated fully developed settlements for known and anticipated claims. Any resulting adjustments to previously recorded reserves are reflected in current operating results. We do not accrue for general or unspecific business risks. Share-based Compensation Equity Restricted Share and Restricted Share Unit Awards — The fair value of equity instruments is measured based on the share price on the grant date and is recognized over the vesting period. These awards contain service, market, and/or performance conditions. For awards containing only a service or a market condition, we have elected to recognize compensation costs using the straight-line method over the requisite service period for the entire award. For awards containing a market condition, the fair value of the award is measured using the Monte Carlo simulation under a lattice model approach. For awards containing a performance condition, the fair value is the grant date close price and compensation expense is not recognized until we conclude that it is probable that the performance condition will be met. We reassess the probability at least quarterly. See Note 20. Defined Benefit Pension and Postretirement Benefit Plans We recognize the funded status of our defined benefit pension plans and postretirement benefit plans in the Consolidated Balance Sheets. The funded status is measured as the difference between the fair value of plan assets and the benefit obligation at the measurement date. The benefit obligation for the defined benefit plans is the projected benefit obligation (PBO), which represents the actuarial present value of benefits expected to be paid upon retirement based on employee services already rendered and estimated future compensation levels. The benefit obligation for our postretirement benefit plans is the accumulated postretirement benefit obligation (APBO), which represents the actuarial present value of postretirement benefits attributed to employee services already rendered. The fair value of plan assets related to our defined benefit plan represents the current market value of assets held in a trust fund, which is established for the sole benefit of plan participants. If the fair value of plan assets exceeds the benefit obligation, the plan is overfunded, and the excess is recorded as a prepaid pension asset. On the other hand, if the benefit obligation exceeds the fair value of plan assets, the plan is underfunded, and the deficit is recorded as pension and postretirement healthcare benefits obligation in the Consolidated Balance Sheet. The portion of the pension and postretirement healthcare obligations payable within the next 12 months is recorded in accrued liabilities in the Consolidated Balance Sheet. Net periodic pension and postretirement benefit cost represents the aggregation of service cost, interest cost, expected return on plan assets, amortization of prior service costs or credits and actuarial gains or losses previously recognized as a component of OCI and it is recorded in the Consolidated Statement of Income. Net periodic cost is recorded in cost of goods sold and selling, general and administrative expenses in the Consolidated Statement of Income based on the employees’ respective functions. Actuarial gains or losses represents the effect of remeasurement on the benefit obligation principally driven by changes in the plan actuarial assumptions. Prior service costs or credits arise from plan amendments. The actuarial gains or losses and prior service costs or credits are initially recognized as a component of Other comprehensive income (loss) in the Consolidated Statement of Comprehensive Income. Those gains or losses and prior service costs or credits are subsequently recognized as a component of net periodic cost. The measurement of benefit obligations and net periodic cost is based on estimates and assumptions approved by management. These valuations reflect the terms of the plans and use participant-specific information such as compensation, age and years of service, as well as certain assumptions, including estimates of discount rates, expected return on plan assets, rate of compensation increases and mortality rates. Defined Contribution Plans — We recognize our contribution as expense when they are due. The expense is recorded in cost of goods sold or selling, general and administrative expenses the Consolidated Statement of Income based on the employees’ respective functions. Multiemployer Plan — We treat our multiemployer plan like a defined contribution plan. A pension plan to which two or more unrelated employers contribute is generally considered to be a multiemployer plan. As a defined contribution plan, we recognize the contribution for the period as a net benefit cost and any contributions due and unpaid as a liability. Recently Issued Accounting Pronouncements In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform Financial Reporting”. This amendment is elective in nature. Amongst other aspects, this standard provides for practical expedients and exceptions to current accounting standards that reference a rate which is expected to be dissolved (e.g., London Interbank Offered Rate “LIBOR”) as it relates to hedge accounting, contract modifications and other transactions that reference this rate, subject to meeting certain criteria. The standard is effective for all entities as of March 12, 2020 through December 31, 2022. In December 2022, the FASB issued ASU 2022-06, which defers the sunset date of ASC 848, Reference Rate Reform, from December 31, 2022 to December 31, 2024. ASU 2022-06 is effective immediately for all entities.

Revenue

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Nature of Contracts and Performance Obligations We primarily generate revenue from selling TiO 2 pigment products and related co-products, primarily zircon and pig iron, to our customers. These products are used for the manufacture of paints, coatings, plastics, paper, and a wide range of other applications. We account for a contract with our customer when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance, and collectability of consideration is probable. Our promise in a contract typically relates to the transferring of a product or multiple distinct products that are substantially the same and that have the same pattern of transfer, representing a single performance obligation within a contract. We have elected to account for shipping and handling activities that occur after control of the products has transferred to the customer as contract fulfillment activities, rather than a separate performance obligation. Amounts billed to a customer in a sales transaction related to shipping and handling activities continue to be reported as “Net sales” and related costs as “Cost of goods sold” in the Consolidated Statements of Income. The duration of our contract period is one year or less. As such, we have elected to recognize incremental costs incurred to obtain contracts, which primarily consist of commissions paid to third-party sales agents, as “Selling, general and administrative expenses” in the Consolidated Statements of Income. Furthermore, we have elected not to disclose the value of unsatisfied performance obligations at each period end, given the original expected duration of our contracts are one year or less. Transaction Price Revenue is measured as the amount of consideration that we expect to be entitled in exchange for transferring products to the customer. The transaction price typically consists of fixed cash consideration. We also offer various incentive programs to our customers, such as rebates, discounts, and other price adjustments that represent variable consideration. We estimate variable consideration and include such consideration amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us. We adjust our estimate of revenue at the earlier of when the amount of consideration we expect to receive changes or when the consideration becomes fixed. Sales returns rarely happen in our business; therefore, it is unlikely that a significant reversal of revenue will occur. Sales and similar taxes we collect on behalf of governmental authorities are excluded from the transaction price for the determination of revenue. The expected costs associated with product warranties continue to be recognized as expense when the products are sold. Customer payment terms and conditions vary by contract and customer, although the timing of revenue recognition typically does not differ from the timing of invoicing. Additionally, as we generally do not grant extended payment terms, we have determined that our contracts generally do not include a significant financing component. Revenue Recognition We recognize revenue at a point in time when the customer obtains control of the promised products. For most transactions this occurs when products are shipped from our manufacturing facilities or at a later point when control of the products transfers to the customer at a specified destination or time. Contract Balances Contract assets represent our rights to consideration in exchange for products that have transferred to a customer when the right is conditional on situations other than the passage of time. For products that we have transferred to our customers, our rights to the consideration are typically unconditional and only the passage of time is required before payments become due. These unconditional rights are recorded as accounts receivable. As of December 31, 2022, and December 31, 2021, we did not have material contract asset balances. Contract liabilities represent our obligations to transfer products to a customer for which we have received consideration from the customer. When a customer has poor credit worthiness, we may receive advance payment that is accounted for as deferred revenue. Deferred revenue is earned when control of the product transfers to the customer, which is typically within a short period of time from when we received the advanced payment. Contract liability balances as of December 31, 2022 and December 31, 2021 were less than $1 million and $2 million, respectively. Contract liability balances were reported as “Accrued liabilities” in the Consolidated Balance Sheets. All material contract liabilities as of December 31, 2021 and 2020 were recognized as revenue in “Net sales” in the Consolidated Statements of Income during the first quarter of 2022 and first quarter of 2021, respectively. Disaggregation of Revenue We operate under one operating and reportable segment, Tronox. See Note 23 for details. We disaggregate our revenue from contracts with customers by product type and geographic area. We believe this level of disaggregation appropriately depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors and reflects how our business is managed. Net sales to external customers by geographic areas where our customers are located were as follows: Year Ended December 31, 2022 2021 2020 North America $ 790 $ 743 $ 716 South and Central America 264 252 181 Europe, Middle-East and Africa 1,335 1,398 1,013 Asia Pacific 1,065 1,179 848 Total net sales $ 3,454 $ 3,572 $ 2,758 The 2020 amounts by geographic area in table above have been corrected for an increase and decrease of $78 million to Asia Pacific and North America, respectively, as well as an increase and decrease of $134 million to Europe, Middle-East and Africa and South and Central America, respectively. Net sales from external customers for each similar type of product were as follows: Year Ended December 31, 2022 2021 2020 TiO 2 $ 2,693 $ 2,793 $ 2,176 Zircon 438 478 283 Other products 323 301 299 Total net sales $ 3,454 $ 3,572 $ 2,758 Other products mainly include pig iron, TiCl 4 and other mining products. The nature, amount, timing and uncertainty of revenue and cash flows typically do not differ significantly among different products.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our operations are conducted through various subsidiaries in a number of countries throughout the world. We have provided for income taxes based upon the tax laws and rates in the countries in which operations are conducted and income is earned. Income (loss) before income taxes is comprised of the following: Year Ended December 31, 2022 2021 2020 United Kingdom $ (130) $ (16) $ (12) International 438 390 126 Income before income taxes $ 308 $ 374 $ 114 The income tax (provision) benefit is summarized below: Year Ended December 31, 2022 2021 2020 United Kingdom: Current $ — $ (1) $ (1) Deferred — — (10) International: Current (69) (55) (17) Deferred 261 (15) 909 Income tax benefit (provision) $ 192 $ (71) $ 881 The following table reconciles the applicable statutory income tax rates to our effective income tax rates for “Income tax (provision) benefit” as reflected in the Consolidated Statements of Income. Year Ended December 31, 2022 2021 2020 Statutory tax rate 19 % 19 % 19 % Increases (decreases) resulting from: Tax rate differences 9 7 10 Disallowable expenditures 8 2 17 Valuation allowances (100) (27) (849) Corporate reorganization — 17 (96) Tax rate changes (3) 2 (8) State and local taxes 1 1 5 Prior year accruals — (2) 131 Branch taxation — — — Withholding taxes 2 2 — Tax credits — (2) (2) Expiration of net operating loss 2 — — Other, net — — — Effective tax rate (62) % 19 % (773) % Tronox Holdings plc is a U.K. public limited company and the parent company for the business group. The statutory tax rate in the U.K. at December 31, 2022, 2021 and 2020 was 19%. The effective tax rates in 2022, 2021 and 2020 are all influenced by a variety of factors, primarily income and losses in jurisdictions with valuation allowances, changes in tax rates, disallowable expenditures, prior year accruals, and rates different than the United Kingdom statutory rate. The valuation allowances in each year were impacted by items other than income and losses as follows: 2022 was impacted by the significant release of valuation allowances in Australia, 2021 was impacted by the release of a valuation allowance in Saudi Arabia and the liquidation of an inactive Dutch subsidiary with a valuation allowance against its worthless net operating losses, and 2020 was impacted by the release of valuation allowances in Brazil and the U.S. and the recording of valuation allowances in Saudi Arabia and the U.K. Additional factors of significance in the above table are as follows: 1) the disallowance expenditures amount for 2022 includes the Venator settlement, 2) the Corporate reorganization amount for 2021 includes the liquidation of the inactive Dutch subsidiary and the write-off of its net operating losses, 3) the Corporate reorganization amounts for 2021 and 2020 include the restructuring of our Australian entities, and 4) the Prior year accrual amount for 2020 includes the amendment of prior year Australian tax returns in resolution of a tax audit. Each of these additional factors were fully offset by valuation allowances. The Company reached an agreement with the Australian Tax Office ("ATO") during the year ended December 31, 2020 for the tax years 2016 through 2019 related to the companies operating in Australia acquired in the Cristal transaction, which were under examination by the ATO. Cash tax payments to be made pursuant to this agreement are not reflected in the above table due to the indemnification clause of the Cristal Transaction purchase contract. As part of the agreement, $79 million in deferred tax assets related to Australian NOLs were lost. The change to deferred taxes was fully offset by a valuation allowance and results in no impact to the consolidated provision. The NOL adjustment from the ATO agreement is reflected in the "Prior year accruals" line of the effective tax rate table. Changes in our state apportionment factors and state statutory rate changes caused our overall effective state tax rates to change. Due to the large deferred tax asset created by the Anadarko litigation settlement in 2014, these state rate changes have a material impact on deferred taxes for 2020. During 2020, tax law changes fully repealed the future Netherlands rate reduction, and this benefit is also reflected in the "Tax rate changes" line. Net deferred tax assets (liabilities) at December 31, 2022 and 2021 were comprised of the following: December 31, 2022 2021 Deferred tax assets: Net operating loss and other carryforwards $ 1,739 $ 1,720 Property, plant and equipment, net 200 220 Reserves for environmental remediation and restoration 47 43 Obligations for pension and other employee benefits 46 58 Investments 4 4 Grantor trusts 621 636 Inventories, net 6 8 Interest 190 214 Lease liabilities 48 23 Other accrued liabilities 2 3 Foreign exchange 1 9 Other 5 7 Total deferred tax assets 2,909 2,945 Valuation allowance associated with deferred tax assets (1,527) (1,841) Net deferred tax assets 1,382 1,104 Deferred tax liabilities: Inventories, net (3) (5) Property, plant and equipment, net (228) (216) Intangible assets, net (15) (22) Lease assets (38) (24) Foreign exchange (4) (1) Other (14) (8) Total deferred tax liabilities (302) (276) Net deferred tax asset $ 1,080 $ 828 Balance sheet classifications: Deferred tax assets — long-term $ 1,233 $ 985 Deferred tax liabilities — long-term $ (153) $ (157) Net deferred tax asset $ 1,080 $ 828 The net deferred tax assets reflected in the above table include deferred tax assets related to grantor trusts, which were established as Tronox Incorporated emerged from bankruptcy during 2011. The balances relate to the assets contributed to such grantor trusts by Tronox Incorporated and the proceeds from the resolution of previous litigation of $5.2 billion during 2014, which resulted in additional deferred tax assets of $2.0 billion. As the grantor trusts continue to spend funds received from the litigation and earn income from the investment of those funds, the U.S. net operating loss will increase or decrease. The 2021 amounts included within the Property, plant and equipment, net and Valuation allowance associated with deferred tax asset captions in the table above have each been corrected for an increase of $113 million to gross up historical amounts. There was a decrease to our valuation allowance of $314 million during 2022 and a decrease of $98 million in 2021. The table below sets forth the changes, by jurisdiction: December 31, 2022 2021 United Kingdom $ 13 $ (1) United States (5) (19) Australia (314) (43) The Netherlands — (24) Saudi Arabia — (11) Brazil — — Switzerland (8) — Belgium — — Total (decrease) increase in valuation allowances $ (314) $ (98) During the year ended December 31, 2022, we determined that sufficient positive evidence existed to reverse a portion of the valuation allowance attributable to the Australian deferred tax assets which we now believe the Company will be able to utilize in future years. This reversal resulted in a non-cash deferred tax benefit of $300 million. Our analysis considered all positive and negative evidence, including (i) three years of cumulative income of our Australian subsidiaries, (ii) our continuing and improved profitability over the last twelve months, (iii) estimates of continued profitability based on updated to our latest forecasts, (iv) changes in the factors that drove losses in the past, and (v) an evaluation of specific deferred tax assets for limitations under certain Australian tax provisions. Based on this analysis, we concluded that it is more likely than not that our Australian subsidiaries will be able to utilize all of their deferred tax assets except for those which are classified as Capital Gains Tax (CGT) assets. These CGT assets represent losses which can only be utilized against CGT gains, and because the Company has no foreseeable source of CGT gains, we will continue to carry an Australian valuation allowance with a current estimated value of $471 million. During the year ended December 31, 2021, the Company liquidated an inactive Dutch subsidiary with a valuation allowance against its worthless net operating losses, and because of improved operations, the Company reversed the valuation allowance in Saudi Arabia which had been established during the year December 31, 2020. During the year ended December 31, 2020, we determined sufficient positive evidence existed to reverse a portion of the valuation allowance attributable to the deferred tax assets associated with our operations in the U.S. This reversal resulted in a non-cash deferred tax benefit of $909 million. Our analysis considered all positive and negative evidence and concluded that it was more likely than not that our U.S. subsidiaries will be able to utilize all of their deferred tax assets with an indefinite life. A portion of the U.S. deferred tax assets are attributable to NOLs incurred in prior years which are subject to expiration in future years. Our analysis did not support that these limited-life NOLs would be utilized before their expiration, and it is against these deferred tax assets in the U.S. that the Company continues to carry a valuation allowance with a current estimated value of $1,021 million. During the year ended December 31, 2020, we also determined sufficient positive evidence existed to reverse the valuation allowance attributable to the deferred tax assets associated with our operations in Brazil. This reversal resulted in a non-cash deferred tax benefit of $8 million. Our analysis considered all positive and negative evidence, the most significant of which was the continuing and improved profitability of the Brazilian company subsequent to its acquisition in 2019 and estimates of continued profitability based on updates to our latest forecasts. Based on this analysis, we concluded that it is more likely than not that our Brazilian subsidiary will be able to utilize all of its deferred tax assets. During the year ended December 31, 2020, we established a valuation allowance against the net deferred tax assets in the United Kingdom. The addition of this valuation allowance resulted in a non-cash deferred tax provision of $10 million. Forecasted changes to intercompany interest is recent negative evidence now impacting our analysis. At December 31, 2022, the table above reflects full valuation allowances related to the total net deferred tax assets in Switzerland and the United Kingdom, as we cannot objectively assert that these deferred tax assets are more likely than not to be realized. Future provisions for income taxes will include no tax benefits with respect to losses incurred and tax expense only to the extent of current tax payments until the valuation allowances are eliminated. Additionally, we have valuation allowances against specific tax assets in Australia, South Africa and the U.S. These conclusions were reached by the application of ASC 740, Income Taxes , and require that all available positive and negative evidence be weighted to determine whether a valuation allowance should be recorded. The more significant evidential matter in Switzerland and the United Kingdom relates to cumulative book losses. The most significant evidential matter for Australia and South Africa relates to capital losses and assets that cannot be depleted or depreciated for tax purposes. The deferred tax assets generated by tax loss carryforwards in Switzerland and the United Kingdom have been fully offset by valuation allowances. In the United States, the deferred tax assets generated by tax loss carryforwards are partially offset by a valuation allowance to the extent they are subject to expiration. The expiration of these carryforwards at December 31, 2022 is shown below. The Australian, Saudi Arabian, French, Brazilian and United Kingdom tax loss carryforwards do not expire. 2023 2024 2025 2026 2027 2028 - 2040 Unlimited Total Tax Loss Carryforwards United Kingdom $ — $ — $ — $ — $ — $ — $ (97) $ (97) Australia — — — — — — (436) (436) The Netherlands — — — — — — (83) (83) France — — — — — — (180) (180) Saudi Arabia — — — — — — (6) (6) Switzerland (80) — — — — — — (80) China — — — — (5) — — (5) Brazil — — — — — — (10) (10) U.S. Federal — — — — — (3,959) (334) (4,293) U.S. State (14) (12) (40) (75) (27) (4,060) (19) (4,247) Total tax loss carryforwards $ (94) $ (12) $ (40) $ (75) $ (32) $ (8,019) $ (1,165) $ (9,437) At December 31, 2022, Tronox Holdings plc had foreign subsidiaries with undistributed earnings. Although we would not be subject to income tax on these earnings, amounts totaling $454 million are in specific jurisdictions which we assert are indefinitely reinvested outside of the parents' taxing jurisdictions. These amounts could be subject to withholding tax if distributed, but the Company has made no provision for tax related to these undistributed earnings. The Company has removed its assertion that earnings in China are indefinitely reinvested, and the withholding tax accruals for potential repatriations from that jurisdiction are now reflected in the effective tax rate reconciliation above. The noncurrent liabilities section of our Consolidated Balance Sheet does not reflect any reserves for uncertain tax positions for either 2022 or 2021. Our Chinese returns are closed through 2018. Our U.K. and Brazilian returns are closed through 2016. Our Australian, South African, and U.S. returns are closed through 2018. Our Netherlands and French returns are closed through 2019. We believe that we have made adequate provision for income taxes that may be payable with respect to years open for examination; however, the ultimate outcome is not presently known and, accordingly, additional provisions may be necessary and/or reclassifications of noncurrent tax liabilities to current may occur in the future.

Accounts Receivable Securitizat

Accounts Receivable Securitization Program	12 Months Ended

Transfers and Servicing [Abstract]
Accounts Receivable Securitization Program	Accounts Receivable Securitization Program On March 15, 2022, the Company entered into an accounts receivable securitization program (“Securitization Facility”) with a financial institution ("Purchaser"), through our wholly-owned special purpose bankruptcy-remote subsidiary Tronox Securitization LLC (“ SPE”). The purpose of this program is to enhance the Company's financial flexibility by providing additional liquidity. The Securitization Facility permitted the SPE to sell accounts receivable up to $75 million (the “Facility Limit”). Under the Securitization Facility, our wholly-owned U.S. operating subsidiary, Tronox LLC (“Originator”), sells its entire accounts receivable on a periodic basis to the SPE. The SPE in turn sells undivided interests in the receivables that meet certain eligibility criteria, pursuant to the terms of a receivable purchase agreement, to the Purchaser in exchange for cash, not to exceed the Facility Limit. The SPE retains the remaining receivables as unsold receivables which are pledged as a collateral for the sold receivables to which the purchaser is granted a first priority security interest. Following the sale of the receivables by the Originator to the SPE, the receivables are legally isolated from Tronox and its affiliated entities, and upon the subsequent sale and transfer of the receivables from the SPE to the administrative agent, effective control of the receivables is passed to the purchaser, which has all rights, including the right to pledge or sell the receivables. Any new receivables that are not sold to the purchaser by the SPE are added to the unsold receivables held as collateral. During March 2022, the Company sold accounts receivable having an aggregate face value of $75 million to the Purchaser in exchange for cash proceeds of $75 million. In November 2022, the Company amended the receivable purchase agreement to expand the program to include receivables generated by its wholly-owned Australian operating subsidiaries, Tronox Pigment Pty Ltd., Tronox Pigment Bunbury Ltd. and Tronox Mining Australia Ltd. which increased the Facility Limit to $200 million and extended the program term to November 2025. Following this amendment, we sold additional accounts receivable in exchange for net cash proceeds of $72 million, for a total aggregate amount of $147 million for the combined program. For the year ended December 31, 2022, the Company sold to the Purchaser accounts receivable a total of $123 million which resulted in the Company recording $24 million within "Accounts Payable" on the Consolidated Balance Sheet at December 31, 2022 as this amount is due to the Purchaser as a result of a periodic decrease in accounts receivable sold to the Purchaser, which was paid in January 2023.

The Prior Term Loan Facility consisted of a U.S. dollar term facility in an aggregate principal amount of $2.15 billion (the “Term Loans”) with our subsidiary, Tronox Finance LLC (“Tronox Finance”) as the borrower. The Prior Term Loan Facility bore interest at the “Applicable Rate” defined by reference to a grid-pricing matrix that relates to our First Lien Net Leverage Ratio and was issued net of an original issue discount of $11 million. On September 22, 2017, we entered into a global senior secured asset-based syndicated revolving credit facility with Wells Fargo Bank, N.A. (the “Wells Fargo Revolver”). The Wells Fargo Revolver which initially provided us with up to $550 million of revolving credit lines, with an $85 million sublimit for letters of credit, and had a maturity date of September 22, 2022. Our availability of revolving credit loans and letters of credit was subject to a borrowing base. Borrowings bore interest at our option, at either an adjusted London Interbank Offered Rate (“LIBOR”) plus an applicable margin that ranges from 1.25% to 1.75%, or a base rate, which was defined to mean the greatest of (a) the administrative agent’s prime rate, (b) the Federal funds effective rate plus 0.50% and (c) the adjusted LIBOR for a one month period plus 1.00% plus a margin that ranges from 0.25% to 0.75%, in each case, based on the average daily borrowing availability. The Wells Fargo Revolver was terminated during the year ended December 31, 2021 as a result of the Cash Flow Revolver (defined below). In December 2020, the Company made a voluntary prepayment of $200 million on the Prior Term Loan Facility. As a result of the voluntary prepayment, we recorded $2 million in "Loss on extinguishment of debt" within the Consolidated Statement of Income for the year ended December 31, 2020. No prepayment penalties were required as a result of this principal prepayment. On March 11, 2021, Tronox Finance LLC entered into an amendment and restatement of its Prior Term Loan Facility pursuant to which, among other thing, we amended and restated the Prior Term Loan Facility with a new amended and restated first lien credit agreement dated as of September 22, 2017 (as amended through and including March 11, 2021) with a syndicate of lenders and HSBC Bank USA, National Association, as administrative agent and collateral agent. The new amended and restated first lien credit agreement provides the Company with (a) a new seven-year term loan facility ("Term Loan Facility") in an aggregate principal amount of $1.3 billion and (b) new five-year cash flow revolving facility (the "Cash Flow Revolver") providing initial revolving commitments of $350 million and a sublimit of $125 million for letters of credit. The maturity date on the Term Loan Facility and the Cash Flow Revolver is March 11, 2028 and March 11, 2026, respectively. The Term Loan Facility shall bear interest at either the base rate or an adjusted LIBOR rate, in each case plus an applicable margin. The applicable margin in respect of the Term Loan Facility is either 1.50% or 1.25%, for base rate loans, or 2.50% or 2.25%, for adjusted LIBOR rate loans, in each case determined based on, initially the passage of time, and thereafter upon the Company’s first lien net leverage ratio at the applicable time. Interest is payable on the Term Loan Facility on the last business of each March, June, September and December. Based on our first lien net leverage ratio, the applicable margin under the Term Loan Facility as of December 31, 2022 was LIBOR plus a margin of 2.25%. The Cash Flow Revolver shall bear interest at either the base rate or adjusted LIBOR rate, in each case plus an applicable margin. The applicable margin in respect of the Cash Flow Revolver is either 1.25%, 1.00% or 0.75% for base rate loans, or 2.25%, 2.00% or 1.75%, for adjusted LIBOR Rate Loans, in each case determined based on, initially the passage of time, and thereafter upon the Company’s first lien net leverage ratio at the applicable time. The Term Loan Facility requires the Borrower to pay customary agency fees. In connection with entering into the Term Loan Facility, the Company terminated all remaining commitments and repaid all obligations under its Prior Term Loan Facility and Wells Fargo Revolver. Additionally, we repaid $313 million of the principal under the Prior Term Loan Facility with cash on hand. Commencing June 30, 2021, the Cash Flow Revolver contains a springing financial covenant when a loan amount is drawn exceeding 35% of the Cash Flow Revolver. In this instance, the first lien net leverage ratio shall not exceed 4.75x at quarter end testing period. As a result of this transaction in accordance with ASC 470, we recognized approximately $4 million in "Loss on Extinguishment of Debt" recorded in the Consolidated Statement of Income for the year ended December 31, 2021. Additionally, during the year ended December 31, 2021, the Company made several voluntary prepayments totaling $398 million on the Term Loan Facility. As a result, we recognized approximately $9 million in "Loss on Extinguishment of Debt" recorded in the Consolidated Statement of Income for the year ended December 31, 2021. During the year ended December 31, 2022, we drew down $133 million on our Cash Flow Revolver and repaid $103 million as of December 31, 2022. As of December 31, 2022, there was $30 million outstanding revolving credit loans (recorded within "Short-term debt" on the Consolidated Balance Sheet) under the Cash Flow Revolver and $20 million of issued and undrawn letters of credit under the Cash Flow Revolver. Additionally, in connection with the sale of the Hawkins Point Plant (refer to Note 18 - Commitments & Contingencies for further details), in December 2022, a $50 million undrawn letter of credit was issued as a bi-lateral, stand-alone arrangement. Debt issuance costs associated with the Cash Flow Revolver of $2 million were included in “Other long-term assets” in the Consolidated Balance Sheets at December 31, 2022 and are being amortized over the life of the Cash Flow Revolver. The average effective interest rate on the Cash Flow Revolver was 5.1% for the year ended December 31, 2022. On April 4, 2022, Tronox Finance LLC (the "Borrower"), the Borrower's indirect parent company, Tronox Holdings plc (the "Company"), certain of the Company's subsidiaries, the incremental term lender party thereto, and HSBC Bank USA. National Association, as Administrative Agent and Collateral Agent, entered into Amendment No. 1 to the Amended and Restated First Lien Credit Agreement (the "Amendment"). The Amendment provides the Borrower with a new seven-year incremental term loan facility (the "2022 Term Loan Facility" and, the loans thereunder, the "2022 Incremental Term Loans") under its credit agreement in an aggregate initial principal amount of $400 million. The obligations of the Borrower under the 2022 Term Loan Facility are guaranteed and secured by the same guarantees and liens under the existing credit agreement of the Term Loan Facility (as discussed above). The 2022 Incremental Term Loans are a separate class of loans under the credit agreement, and if the Borrower elects to make an optional prepayment under the credit agreement or is required to make a mandatory prepayment under the credit agreement, the Borrower, may, in each case, select which class or classes of loans to prepay. The 2022 Incremental Term Loans will amortize in equal quarterly installments in an aggregate annual amount equal to 1.0% of the original principal amount of the 2022 Incremental Term Loans commencing with the second full fiscal quarter after the effective date of the 2022 Incremental Term Loan Facility. The final maturity of the 2022 Incremental Term Loans will occur on the seventh anniversary of the effective date of the 2022 Incremental Term Loan Facility. The 2022 Incremental Term Loan Facility permits amendments thereto whereby individual lenders may extend the maturity date of their outstanding loans upon the Borrower's request without the consent of any other lender, so long as certain conditions are met. The 2022 Incremental Term Loans shall bear interest, at the Borrower's option, at either the base or the SOFR rate, in each case plus an applicable margin. The applicable margin in respect of the 2022 Incremental Loans is 2.25% per annum, for base rate loans, or 3.25% per annum, for SOFR rate loans. The 2022 Incremental Term Loans have an interest rate floor of 0.50%. As of December 31, 2022, the applicable margin under the 2022 Term Loan Facility was 3.25%. The 2022 Incremental Term Loan Facility contains the same negative covenants applicable to the term loans outstanding under the Existing Credit Agreement immediately prior to the effectiveness of the Amendment, which covenants, subject to certain limitations, thresholds and exceptions, limit the Company and its restricted subsidiaries to (among other restrictions): incur indebtedness; grant liens; pay dividends and make subsidiary and certain other distributions; sell assets; make investments; enter into transactions with affiliates; and make certain modifications to material documents (including organizational documents). The proceeds of the 2022 Incremental Term Loans were used on April 4, 2022, along with cash on hand, to redeem all outstanding 6.5% Senior Secured Notes due 2025 issued by Tronox Incorporated under the Indenture dated as of May 1, 2020 with Wilmington Trust, National Association, as Trustee and Collateral Agent and to pay transaction related costs and expenses. As a result of this transaction, we recognized approximately $21 million, including a call premium of $18 million, in "Loss on extinguishment of debt" on the Consolidated Statement of Income for the year ended December 31, 2022. As of December 31, 2022, the total outstanding principal balance is $397 million, of which $4 million is recorded within "Current portion of long-term debt" on the Consolidated Balance Sheet.

During the year ended December 31, 2022, we paid the outstanding balance of $500 million on the 6.5% Senior Secured Notes due 2025 utilizing the proceeds of the 2022 Term Loan Facility (discussed above), along with cash on hand.

Repayment of the note payable is based on a fixed U.S. dollar per metric ton quantity of MGT delivered by us to Advanced Metal Industries Cluster and Toho Titanium Metal Co. Ltd (ATTM) over time and therefore the ultimate maturity date is variable in nature.

Insurance premium financing In August 2022, the Company entered into a $21 million insurance premium financing agreement with a third-party financing company. The balance will be repaid in monthly installments over 10 months at a 5% fixed annual interest rate. As of December 31, 2022, the financing balance was $10 million and is recorded in "Short-term debt" in the Consolidated Balance Sheet. Debt Covenants At December 31, 2022, we are in compliance with all financial covenants in our debt facilities. Interest and Debt Expense, Net Interest and debt expense, net in the Consolidated Statements of Income consisted of the following: Year Ended December 31, 2022 2021 2020 Interest on debt $ 132 $ 148 $ 174 Amortization of deferred debt issuance costs and discounts on debt 8 11 10 Capitalized interest (17) (7) (2) Interest on capital leases and letters of credit and commitments 2 5 7 Total interest and debt expense, net $ 125 $ 157 $ 189 In connection with obtaining debt, we incurred debt issuance costs, which are being amortized through the respective maturity dates using the effective interest method for our long-term debt and on a straight-line basis for our Cash Flow Revolver.

The agreements expire in September 2024. The Company's objectives in using the interest-rate swap agreements are to add stability to interest expense and to manage its exposure to interest rate movements. These interest rate swaps have been designated as cash flow hedges and involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. There was no impact associated with the New Term Loan Facility as the hedge remained highly effective. Fair value gains or losses on these cash flow hedges are recorded in other comprehensive (loss) income and are subsequently reclassified into interest expense in the same periods during which the hedged transactions affect earnings. For the year ended December 31, 2022, 2021 and 2020, the amounts recorded in interest expense related to the interest-rate swap agreements were $4 million, $16 million and $10 million, respectively. At December 31, 2022 and December 31, 2021, the net unrealized gain was $30 million and the unrealized loss was $25 million, respectively, and was recorded in "Accumulated other comprehensive loss" on the Consolidated Balance Sheet. Foreign Currency Risk From time to time, we enter into foreign currency contracts used to hedge forecasted third party non-functional currency sales for our South African subsidiaries and forecasted non-functional currency cost of goods sold for our Australian subsidiaries. These foreign currency contracts are designated as cash flow hedges. Changes to the fair value of these foreign currency contracts are recorded as a component of other comprehensive (loss) income, if these contracts remain highly effective, and are recognized in net sales or costs of goods sold in the period in which the forecasted transaction affects earnings or are recognized in other (expense) income, net when the transactions are no longer probable of occurring. As of December 31, 2022, we had no outstanding amounts to reduce the exposure of our Australian subsidiaries’ cost of sales to fluctuations in currency rates or to reduce the exposure of our South African subsidiaries' third party sales to fluctuations in currency rates. At December 31, 2022, there was an unrealized net loss of $4 million recorded in "Accumulated other comprehensive loss" on the Consolidated Balance Sheet, which is expected to be recognized in earnings over the next twelve months. At December 31, 2021, there was an unrealized net gain of $15 million recorded in "Accumulated other comprehensive loss" on the Consolidated Balance Sheet.

We determined the fair value of the Standard Bank Term Loan Facility utilizing transactions in the listed markets for similar liabilities, which under the fair value hierarchy is a Level 2 input. The fair value of the Australian Government Loan and MGT Loan is based on the contracted amount which is a Level 2 input. We determined the fair value of the foreign currency contracts and interest rate swaps using inputs other than quoted prices in active markets that are observable either directly or indirectly. The fair value hierarchy for the foreign currency contracts and interest rate swaps is a Level 2 input. The carrying value of cash and cash equivalents, restricted cash, accounts receivable and accounts payable approximate fair value due to the short-term nature of these items.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Purchase and Capital Commitments —At December 31, 2022, purchase commitments were $348 million for 2023, $168 million for 2024, $149 million for 2025, $152 million for 2026, $155 million for 2027, and $1,594 million thereafter. Letters of Credit —At December 31, 2022, we had outstanding letters of credit and bank guarantees of $109 million, of which $70 million were letters of credit and $39 million were bank guarantees. Amounts for performance bonds were not material. Environmental Matters — It is our policy to record appropriate liabilities for environmental matters when remedial efforts are probable and the costs can be reasonably estimated. Such liabilities are based on our best estimate of the undiscounted future costs required to complete the remedial work. The recorded liabilities are adjusted periodically as remediation efforts progress or as additional technical, regulatory or legal information becomes available. Given the uncertainties regarding the status of laws, regulations, enforcement policies, the impact of other potentially responsible parties, technology and information related to individual sites, we do not believe it is possible to develop an estimate of the range of reasonably possible environmental loss in excess of our recorded liabilities. We expect to fund expenditures for these matters from operating cash flows. The timing of cash expenditures depends principally on the timing of remedial investigations and feasibility studies, regulatory approval of cleanup projects, remedial techniques to be utilized and agreements with other parties. Included in these environmental matters are the following: Hawkins Point Plant. Residual waste mud, known as Batch Attack Mud, and a spent sulfuric waste stream were deposited in an onsite repository (the “Batch Attack Lagoon”) at a former TiO2 manufacturing site, Hawkins Point Plant in Baltimore, Maryland, operated by Cristal USA, Inc. from 1954 until 2011. We assumed responsibility for remediation of the Hawkins Point Plant when we acquired the TiO2 business of Cristal in April 2019. On December 21, 2022, we sold the Hawkins Point Plant to the Maryland Port Administration ("MPA"), a state agency controlled by the Maryland Department of Transportation. Pursuant to the terms of the transaction, MPA became the lead party in developing and implementing appropriate measures to address, treat, control, and mitigate the environmental conditions at the property under the regulatory oversight of the Maryland Department of the Environment ("MPE"). Under MPA ownership, the Hawkins Point Plant will be utilized for storage and beneficial reuse of dredged material from the Port of Baltimore. In exchange for transferring ownership of the site to MPA, Tronox has agreed to make scheduled, annual payments to MPA which together with scheduled, annual contributions from MPA will be used to remediate the property. The sale of the property to MPA did not have a material impact to the Consolidated Statement of Income. As of December 31, 2022, we have a provision of $42 million included in "Environmental liabilities" in our Consolidated Balance Sheet for the Hawkins Point Plant consistent with the accounting policy described above. Other Matters — We are subject to a number of other lawsuits, investigations and disputes (some of which involve substantial amounts claimed) arising out of the conduct of our business, including matters relating to commercial transactions, prior acquisitions and divestitures, including our acquisition of Cristal, employee benefit plans, intellectual property, and environmental, health and safety matters. We recognize a liability for any contingency that is probable of occurrence and reasonably estimable. We continually assess the likelihood of adverse judgments of outcomes in these matters, as well as potential ranges of possible losses (taking into consideration any insurance recoveries), based on a careful analysis of each matter with the assistance of outside legal counsel and, if applicable, other experts. Included in these other matters is the following: Venator Materials plc v. Tronox Limited. In May 2019, Venator Materials plc (“Venator”) filed an action in the Superior Court of the State of Delaware alleging among other things that we owed Venator a $75 million “Break Fee” pursuant to the terms of a preliminary agreement dated July 14, 2018 (the “Exclusivity Agreement”). The Exclusivity Agreement required, among other things, Tronox and Venator to use their respective best efforts to negotiate a definitive agreement to sell the entirety of the National Titanium Dioxide Company Limited’s (“Cristal’s”) North American operations to Venator if a divestiture of all or a substantial part of these operations were required to secure the approval of the Federal Trade Commission for us to complete our acquisition of Cristal’s TiO 2 business. In June 2019, we denied Venator's claims and counterclaimed against Venator seeking to recover $400 million in damages from Venator that we suffered as a result of Venator’s breaches of the Exclusivity Agreement. Specifically, we alleged, among other things, that Venator’s failure to use best efforts constituted a material breach of the Exclusivity Agreement and directly resulted in and caused us to sell Cristal’s North American operations to an alternative buyer for $701 million, $400 million less than the price Venator had agreed to in the Exclusivity Agreement. On April 6, 2022, the Judge presiding over the case in the Superior Court of the State of Delaware delivered a directed verdict in favor of Venator without allowing the jury to deliberate. The Company determined not to appeal the Judge's verdict, and as such, on April 18, 2022, the Company and Venator entered into a settlement agreement whereby the Company paid $85 million, inclusive of interest, on April 25, 2022. As a result, we recorded the charge within "Venator settlement" on the Consolidated Statement of Income for the year ended December 31, 2022. Western Australia Stamp Duty Matter. In May 2018, we lodged a pre-transaction determination request for a stamp duty exemption with the Western Australia Office of State Revenue (the “WA OSR”) in connection with our re-domicile transaction (the “Re-Domicile Transaction”) which was subsequently granted by the WA OSR in June 2018 on a preliminary basis. Immediately following the consummation of the Re-Domicile Transaction, we filed a confirmation request for the stamp duty exemption with the WA OSR. Following this confirmation request, we exchanged numerous communications with the WA OSR addressing questions raised and stating our position. In July 2021, the WA OSR informed us that they have reviewed their technical position on the applicability of the stamp duty exemption and have determined that such an exemption is disallowed. On April 8, 2022, the Company lodged an appeal of the WA OSR's decision with the Western Australia State Administrative Tribunal. The Tribunal hearing is currently expected to take place in the second half of 2023. While the Company believes it complied with the rules relevant to obtaining an exemption from stamp duties in connection with the Re-Domicile Transaction, if an unfavorable ruling is received from the Western Australia State Administrative Tribunal and Tronox is not able to successfully appeal such ruling, the stamp duty payable on the Re-Domicile Transaction could result in a material change to our financial statement.

Share-based Compensation	Share-based Compensation Share-based compensation expense consisted of the following: Year Ended December 31, 2022 2021 2020 Total share-based compensation expense from restricted share units $ 26 $ 31 $ 30 The stock compensation expense for the year ended December 31, 2021 is inclusive of a $3 million true up of expense due to the 2020 and 2021 performance grants as well as the acceleration of $2 million of stock compensation expense associated with the retirement agreement entered into with the former CEO on March 18, 2021. Tronox Holdings plc Amended and Restated Management Equity Incentive Plan On March 27, 2019, in connection with the Re-domicile Transaction, Tronox Holdings plc assumed the management equity incentive plan previously adopted by Tronox Limited, which plan was renamed the Tronox Holdings plc Amended and Restated Management Equity Incentive Plan. The amendments to the plan were made to provide, among other things, for the appropriate substitution of Tronox Holdings in place of Tronox Limited and to ensure the compliance with the laws of England and Wales law in place of Australian law. The MEIP permits the grant of awards that are comprised of incentive options, nonqualified options, share appreciation rights, restricted shares, restricted share units, performance awards, and other share-based awards, cash payments, and other forms as the compensation committee of the Board of Directors (the “Board”) in its discretion deems appropriate, including any combination of the above. The maximum number of shares which were initially subjected to awards (inclusive of incentive options) was 20,781,225 ordinary shares and was increased by 8,000,000 on the affirmative vote of our shareholders on June 24, 2020. Restricted Share Units (“RSUs”) On an annual basis, the Company grants RSUs which have time and/or performance conditions. Both the time-based awards and the performance-based awards are classified as equity awards. 2022 Grants - The Company granted both time-based and performance-based awards to certain members of management and to members of the Board. A total of 582,136 of time-based awards were granted to management which will vest ratably over a three-year period ending March 5, 2025. A total of 68,296 of time-based awards were granted to members of the Board of which will vest in May 2023. A total of 533,416 of performance-based awards were granted, of which 266,708 of the awards vest based on a relative Total Shareholder Return ("TSR") calculation and 266,708 of the awards vest based on certain performance metrics of the Company. The non-TSR performance-based awards vest on March 5, 2025 based on the achievement against the target average company performance of three separate performance periods, commencing on January 1 of each 2022, 2023, and 2024 and ending on December 31 of each 2022, 2023 and 2024, for which, for each performance period, the performance metric is an average annual return on invested capital (ROIC) improvement versus 2021 ROIC. Similar to the Company's historical TSR awards granted in prior years, the TSR awards vest based on the Company's three-year TSR versus the peer group performance levels. Given these terms, the TSR metric is considered a market condition for which we used a Monte Carlo simulation to determine the weighted average grant date fair value of $34.41. Similar TSR awards were granted during 2021 and 2020 with grant date fair values of $29.07 and $10.00, respectively, which were calculated utilizing a Monte Carlo simulation.

Retirement Benefits [Abstract]
Pension and Other Postretirement Healthcare Benefits	Pension and Other Postretirement Healthcare Benefits The following provides information regarding our U.S. and foreign plans: U.S. Plans Pension and Postretirement Healthcare Plans — Tronox has one main U.S. defined benefit plan: the U.S. Qualified Plan. Prior to December 2020, the Company also had the U.S. Pension Plan (which was acquired as part of the Cristal acquisition). In December 2020, the U.S. Pension Plan was frozen and merged into the U.S. Qualified Plan. The U.S. Qualified Plan is a funded noncontributory qualified benefit plan which is in accordance with the Employee Retirement Income Security Act of 1974 (“ERISA”) and the Internal Revenue Code. We made contributions into funds managed by a third party, and those funds are held exclusively for the benefit of the plan participants. Benefits under the U.S. Qualified Plan were generally calculated based on years of service and final average pay. The U.S. Qualified Plan was frozen and closed to new participants on June 1, 2009. In October 2022, the Company entered into an irrevocable arrangement with an insurance provider to settle certain lower dollar valued accounts within its frozen U.S Qualified Plan to reduce PBGC premiums. As a result of this arrangement, the Company recorded a non-cash pension settlement charge of approximately $20 million during the fourth quarter of 2022. We also maintain one postretirement healthcare plan - the U.S. retiree welfare plan. International Plans Pension Plans — Tronox has international defined benefit commitments primarily in the United Kingdom ("U.K. DB Scheme") and Saudi Arabia. The U.K. DB Scheme is a funded qualified defined benefit plan in the United Kingdom, which is frozen with no additional benefits accruing to the participants. Benefits under the U.K. DB Scheme are generally calculated based on years of credit service and final compensation when benefits ceased to accrue as defined under the plan provisions. We also maintain a Saudi Arabia Cristal End of Service Benefit plan which provides end of service benefits to qualifying participants. End of service benefits are based on years of service and the reasons for which a participant's services to the Company are terminated. Multiemployer Pension Plan - In prior periods, we maintained a defined benefit plan in the Netherlands (the “Netherlands Plan”) to provide defined pension benefits to qualifying employees of Tronox Pigments (Holland) B.V. and its related companies. During 2014, the Netherlands Plan was replaced with a multiemployer plan, the Netherlands Contribution Plan (the "CDC Plan") effective January 1, 2015. Under the CDC Plan, employees earn benefits based on their pensionable salaries each year determined using a career average benefit formula. The collective bargaining agreement between us and the participants require us to contribute 20.4% of the participants’ pensionable salaries into a pooled fund administered by the industry-wide PGB. The pensionable salary is the annual income of employees subject to a cap, which is adjusted each year to reflect the current requirements of the Netherlands’ Wages and Salaries Tax Act of 1964. Our obligation under this plan is limited to the fixed percentage contribution we make each year. The employees are entitled to any returns generated from the investment activities of the fund. The following table outlines the details of our participation in the CDC Plan for the year ended December 31, 2022. The CDC disclosures provided herein are based on the fund’s 2021 annual report, which is the most recently available public information. Based on the total plan assets and accumulated benefit obligation information in the plan’s annual report, the zone status was green as of December 31, 2021. A green zone status indicates that the plan was at least 80 percent funded. The “FIP/RP Status Pending/Implemented” column indicates whether a financial improvement plan (FIP) or a rehabilitation plan (RP) is either pending or has been implemented. As of December 31, 2022, we are not aware of any financial improvement or rehabilitation plan being implemented or pending. The last column lists the expiration date of the collective-bargaining agreement to which the plan is subject. Pension Protection Act Zone Status Tronox Contributions Pension Fund EIN/Pension Plan Number 2022 2021 FIP/RP Pending/ Implemented 2022 2021 Surcharge Imposed Expiration date of Collective- Bargaining Agreement PGB NA N/A Green No $ 5 $ 5 No 12/31/2024 On the basis of the information available in the CDC Plan 2021 annual report, our contribution does not constitute more than 5 percent of the total contribution to the plan by all participants. During 2022, the fund did not impose any surcharge on us. Postretirement Healthcare Plans — We also maintain postretirement healthcare plans in South Africa (the "South African Plan") and Brazil (the "Brazil Medical Plan"). The South African Plan provides medical and dental benefits to certain South African employees, retired employees and their registered dependents. The South African Plan provides benefits as follows: (i) members employed before March 1, 1994 receive 100% post-retirement and death-in-service benefits; (ii) members employed on or after March 1, 1994 but before January 1, 2002 receive 2% per year of completed service subject to a maximum of 50% post-retirement and death-in-service benefits; and, (iii) members employed on or after January 1, 2002 receive no post-retirement and death-in-service benefits. The Brazil Medical Plan provides post-employment medical benefits to employees who contributed to the medical plan while employed. Retirees receiving a benefit under the plan are required to pay a contribution that varies based on the coverage level elected. Pension and Postretirement Benefit Costs / Obligations Benefit Obligations and Funded Status — The following provides a reconciliation of beginning and ending benefit obligations, beginning and ending plan assets, funded status, and balance sheet classification of our U.S. and international pension plans and other post-retirement benefit plans ("OPEB") as of and for the years ended December 31, 2022 and 2021.

(2) Since the benefits under the U.S Qualified Plan and the U.K. DB Scheme are frozen, the projected benefit obligation and accumulated benefit obligation are the same. Contributions At a minimum, Tronox contributes to its pension plans to comply with local regulatory requirements (e.g., ERISA in the United States). Discretionary contributions in excess of the local minimum requirements are made based on many factors, including long-term projections of the plans' funded status, the economic environment, potential risk of overfunding, pension insurance costs and alternative uses of the cash. Changes to these factors can impact the timing of discretionary contributions from year to year. Pension contributions for its US and international plans were approximately $6 million in 2022 and are currently expected to be approximately $8 million in 2023. The following table provides information for pension plans where the accumulated benefit obligation exceeds the fair value of the plan assets: Pensions 2022 US International Projected benefit obligation (PBO) $ 199 $ 58 Accumulated benefit obligation (ABO) $ 199 $ 39 Fair value of plan assets $ 180 $ — Expected Benefit Payments — The following table shows the expected cash benefit payments for the next five years and in the aggregate for the years 2028 through 2032: 2023 2024 2025 2026 2027 2028-2032 Pensions - US $ 25 $ 21 $ 19 $ 19 $ 18 $ 80 Pensions - International $ 12 $ 10 $ 10 $ 10 $ 10 $ 49 Other Post Retirement Benefit Plans - US $ — $ — $ — $ — $ — $ 1 Other Post Retirement Benefit Plans - International $ — $ — $ 1 $ 1 $ 1 $ 7 Retirement and Postretirement Healthcare Expense — The table below presents the components of net periodic cost associated with the U.S. and foreign plans recognized in the Consolidated Statements of Income for 2022, 2021, and 2020: Pensions Other Postretirement Benefit Plans Year Ended December 31, Year Ended December 31, 2022 2021 2020 2022 2021 2020 Net periodic cost: Service cost $ 5 $ 4 $ 5 $ — $ 1 $ — Interest cost (1) 14 14 17 2 2 1 Expected return on plan assets (1) (24) (26) (22) — — — Net amortization of actuarial loss (1) 4 5 4 — 1 — Settlement losses (gains) (1) 20 — — — — — Curtailment (gains) (1) — — (2) — — — Total net periodic cost $ 19 $ (3) $ 2 $ 2 $ 4 $ 1 ________________ (1) Recorded in Other (expense) income, net in the Consolidated Statement of Income.

Expected Return on Plan Assets — In forming the assumption of the U.S. and international long-term rate of return on plan assets, we considered the expected earnings on funds already invested, earnings on contributions expected to be received in the current year, and earnings on reinvested returns. The long-term rate of return estimation methodology for the Company's pension plans is based on a capital asset pricing model using historical data and a forecasted earnings model. An expected return on plan assets analysis is performed which incorporates the current portfolio allocation, historical asset-class returns, and an assessment of expected future performance using asset-class risk factors. Discount Rate — The 2022 and 2021 rates were selected based on the results of a cash flow matching analysis, which projected the expected cash flows of the plans using a yield curves model developed from a universe of Aa-graded U.S. currency corporate bonds (obtained from Bloomberg) with BVAL scores of 6 or greater. Plan Assets — The investments of the U.S. and International pension plans are managed to meet the future expected benefit liabilities of the plan over the long term by investing in diversified portfolios consistent with prudent diversification and historical and expected capital market returns . Tronox's U.S. and international pension plans’ weighted-average asset allocations at December 31, 2022 and 2021, and the target asset allocation ranges, by major asset category, are as follows: December 31, 2022 2021 US International US International Actual Target Actual Target Actual Target Actual Target Equity securities 49 % 46 % — % — % 49 % 49 % — % — % Debt securities 46 46 37 37 46 48 43 43 Real estate 1 — — — 1 — — — Other 4 8 63 63 4 3 57 57 Total 100 % 100 % 100 % 100 % 100 % 100 % 100 % 100 % The fair values of pension investments as of December 31, 2022 are summarized below: Fair Value Measurement at December 31, 2022 Using: Quoted Prices Significant Other Significant Total Asset category: Equities securities: Global equity securities $ 53 (1) $ — $ — $ 53 Global commingled equity funds 35 (2) — — 35 Debt securities: US government bonds 48 (3) — — 48 Foreign government bonds 19 (3) — — 19 US corporate bonds — 34 (4) — 34 Foreign corporate bonds — 22 (4) — 22 Real Estate: Property/ real estate fund — 1 (5) — 1 Other: Insurance contracts — — 63 (7) 63 Cash & cash equivalents 11 (6) — — 11 Total at fair value $ 166 $ 57 $ 63 $ 286 ________________ (1) For global equity securities, this category is comprised of shares of common stock in both U.S. and international companies from a diverse set of industries and size.

Under the SIP, our regular full-time and part-time employees contribute a portion of their earnings, and we match these contributions up to a predefined threshold. Our matching contribution is 100% of the first 6% of employee contributions. Effective January 1, 2013, we established a profit sharing contribution at 6% of employees’ pay (“discretionary contribution”). A discretionary contribution of 6% was made for 2022, 2021 and 2020. Our matching contribution to the SIP vests immediately; however, our discretionary contribution is subject to vesting conditions that must be satisfied over a three-year vesting period. Contributions under the SIP, including our match, are invested in accordance with the investment options elected by plan participants. Compensation expenses associated with our matching contribution to the SIP was $5 million, $5 million and $4 million during 2022, 2021 and 2020, respectively, which was included in “Selling, general and administrative expenses” in the Consolidated Statements of Income. Compensation expense associated with our discretionary contribution was $5 million in 2022, $5 million in 2021 and $4 million in 2020, which was included in “Selling, general and administrative expenses” in the Consolidated Statements of Income. U.S. Benefit Restoration Plan In 2006, we established the U.S. Benefit Restoration Plan (the “BRP”), a nonqualified defined contribution plan, for employees whose eligible compensation is expected to exceed the IRS compensation limits for qualified plans. Under the BRP, participants can contribute up to 20% of their annual compensation and incentive. Our matching contribution under the BRP is the same as the SIP. Our matching contribution under this plan vests immediately to plan participants. Contributions under the BRP, including our match, are invested in accordance with the investment options elected by plan participants. Compensation expense associated with our matching contribution to the BRP was $1 million, $1 million and $1 million during 2022, 2021 and 2020, respectively, which was included in “Selling, general and administrative expenses” in the Consolidated Statements of Income. South Africa Defined Contribution Plans Tronox Mineral Sands Proprietary Limited, a wholly owned subsidiary of the Company, participates in several defined contribution plans which are registered in the Republic of South Africa and are governed by the South African Pension Funds Act of 1956. These plans provide retirement and other benefits to all permanent employees, and where applicable, retired employees and their dependents. The Company contributes a range of 10% to 15% (depending on the plan) of the employees' predefined pre-tax pensionable earnings. Compensation expense associated with these plans was $7 million, $5 million, and $4 million during 2022, 2021 and 2020, respectively, which was included in both "Costs of goods sold" and "Selling, general and administrative expenses" in the Consolidated Statements of Income.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party TransactionsTasnee / Cristal At December 31, 2022 Cristal International Holdings B.V. (formerly known as Cristal Inorganic Chemical Netherlands Cooperatief W.A.), a wholly-owned subsidiary of Tasnee, continues to own 37,580,000 shares of Tronox, or a 24% ownership interest. On May 9, 2018, we entered into an Option Agreement with AMIC which is owned equally by Tasnee and Cristal. Under the terms of the Option Agreement, AMIC granted us an option (the “Option”) to acquire 90% of a special purpose vehicle (the “SPV”), to which AMIC’s ownership in a titanium slag smelter facility (the “Slagger”) in The Jazan City for Primary and Downstream Industries in KSA will be contributed together with $322 million of AMIC indebtedness (the "AMIC Debt"). The AMIC Debt would remain outstanding debt of the SPV upon exercise of the Option. The Option may be exercised if the Slagger achieves certain production criteria related to sustained quality and tonnage of slag produced (the “Option Criteria”). Likewise, AMIC may require us to acquire the Slagger on the same terms if the Option Criteria are satisfied. Furthermore, pursuant to the Option Agreement and during its term, we agreed to lend AMIC and, upon the creation of the SPV, the SPV, up to $125 million for capital expenditures and operational expenses intended to facilitate the start-up of the Slagger (the “Tronox Loans”). At both December 31, 2022 and 2021, we have lent AMIC the Tronox Loans maximum amount of $125 million, which, together with the related accrued interest of $13 million a nd $9 million, respectively, is recorded within "Other long-term assets" on the Consolidated Balance Sheet. The Option did not have a significant impact on the financial statements as of or for the periods ended December 31, 2022 and 2021. For the years ended December 31, 2022 and 2021, Tronox recorded $60 million and nil , respectively, for purchases of feedstock material produced by the Slagger. Such sales are recorded in "Cost of goods sold" on the Consolidated Statement of Income. At December 31, 2022 and 2021, amounts due related to Slagger feedstock purchases were $14 million and nil, respectively, which are recorded within “Accrued liabilities” on the Consolidated Balance Sheet. On May 13, 2020, we amended the Option Agreement (the "First Amendment") with AMIC to address circumstances in which the Option Criteria cannot be satisfied. Pursuant to the First Amendment, Tronox has the right to acquire the SPV in exchange for (i) our forgiveness of the Tronox Loans principal and accrued interest thereon, and (ii) the SPV's assumption of $36 million of indebtedness plus accrued interest thereon lent by AMIC to the SPV. Under the First Amendment, the SPV would not assume any of the AMIC Debt. Additionally, on May 13, 2020, we amended a Technical Services Agreement that we had entered with AMIC on March 15, 2018, to add project management support services. Under this arrangement, AMIC and its consultants are still responsible for engineering and construction of the Slagger while we provide technical advice and project management services including supervision and management of third party consultants intended to satisfy the Option Criteria. As compensation for these services, Tronox receives a management fee, which is subject to certain success incentives if and when the Slagger achieves the Option Criteria. For both of the years ended December 31, 2022 and 2021, Tronox recorded management fees of $8 million, in “Other (expense) income, net” within the Consolidated Statement of Income. For the years ended December 31, 2022 and 2021, Tronox recorded other technical support fees received under the Technical Services Agreement of $2 million and nil , respectively, in "Selling, general and administrative expenses" on the Consolidated Statement of Income. At December 31, 2022 and 2021, Tronox had a receivable due from AMIC related to management fee and technical support fees of $2 million and $1 million, respectively, that is recorded within “Prepaid and other assets” on the Consolidated Balance Sheet. At December 31, 2022, Tronox had a receivable due from Tasnee of $2 million related primarily to pre-acquisition period tax matters in process with certain tax authorities which are reimbursable from Tasnee. At December 31, 2021 , Tronox had a receivable due from Tasnee of $8 million related primarily to $4 million of stamp duty taxes reimbursable from Tasnee and $3 million for pre-acquisition period tax matters. These receivables are recorded within “Prepaid and other assets” on the Consolidated Balance Sheet. On December 29, 2019, we entered into an agreement with Cristal to acquire certain assets co-located at our Yanbu facility which produce metal grade TiCl4 ("MGT"). Consideration for the acquisition was the assumption by Tronox of a $36 million note payable to Cristal (the "MGT Loan"). MGT is used at a titanium "sponge" plant facility, 65% of the ownership interests of which are held by Advanced Metal Industries Cluster and Toho Titanium Metal Co. Ltd ("ATTM"), a joint venture between AMIC and Toho Titanium Company Ltd. ATTM uses the TiCl4, which we supply by pipeline, for the production of titanium sponge, a precursor material used in the production of titanium metal. On December 17, 2020 we completed the MGT transaction. Repayment of the $36 million note payable is based on a fixed U.S. dollar per metric ton quantity of MGT delivered by us to ATTM over time and therefore the ultimate maturity date is variable in nature. If ATTM fails to purchase MGT from us under certain contractually agreed upon conditions, then at our election we may terminate the MGT supply agreement with ATTM and will no longer owe any amount under the loan agreement with Cristal. We currently estimate the ultimate maturity to be between approximately five was $30 million and $33 million, respectively, of which $7 million and $7 million, respectively, was expected to be paid within the next twelve months. The note payable is recorded within "Long-term debt, net" and "Long-term debt due within one year" on the Consolidated Balance Sheet. For both years ended December 31, 2022 and 2021, Tronox recorded interest expense of $1 million related to the MGT Loan, which is recorded in "Interest expense" on the Consolidated Statement of Income. During the years ended December 31, 2022 and 2021, Tronox recorded $3 million and $4 million , respectively, for MGT Loan repayments to Cristal that is recorded within "Net sales" on the Consolidated Statement of Income. As a result of these transactions we have entered into related to the MGT assets, Tronox recorded $4 million and $8 million for purchase of chlorine gas for the years ended December 31, 2022 and 2021, respectively, from ATTM and such amounts are recorded in "Cost of goods sold" on the Consolidated Statement of Income. The amount due to ATTM as of December 31, 2022 and 2021, for the purchase of chlorine gas was $1 million and $1 million, respectively, and is recorded within “Accrued liabilities” on the Consolidated Balance Sheet. During the years ended December 31, 2022 and 2021, Tronox recorded $29 million and $31 million, respectively, for MGT sales made to AMIC. The MGT sales are recorded in “Net sales” on the Consolidated Statement of Income. At December 31, 2022 and December 31, 2021, Tronox had a receivable from AMIC of $6 million and $6 million, respectively, from MGT sales that is recorded within “Prepaid and other assets” on the Consolidated Balance Sheet.

Segment Reporting [Abstract]
Segment Information	Segment Information We operate our business under one operating segment, Tronox , which is also our reportable segment. The Company's chief operating decision maker, who are its Co-CEOs, reviews financial information presented at the consolidated level for purposes of allocating resources and evaluating financial performance. Since we operate our business under one segment, there is no difference between our consolidated results and segment results. We disaggregate revenue from contracts with customers by product type and geographic area as well as sales based on country of production. We believe this level of disaggregation appropriately depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors and reflects how our business is managed. During 2022, 2021 and 2020 our ten largest third-party customers represented 30%, 28%, and 32%, respectively, of our consolidated net sales. During 2022, 2021, and 2020, no single customer accounted for 10 % of our consolidated net sales. Net sales to external customers based on country of production, were as follows: Year Ended December 31, 2022 2021 2020 U.S. operations $ 733 $ 716 $ 653 International operations: United Kingdom 331 396 301 Australia 822 873 637 South Africa 484 441 330 Saudi Arabia 419 420 269 Other - international 665 726 568 Total net sales $ 3,454 $ 3,572 $ 2,758 See Note 3 for further information on revenues. There is no difference between the total consolidated assets and our segment assets. Property, plant and equipment, net, mineral leaseholds, net, and lease right of use assets, net by geographic region, were as follows: December 31, 2022 2021 U.S. operations $ 308 $ 251 International operations: United Kingdom 93 97 Saudi Arabia 226 241 South Africa 705 705 Australia 1,093 1,000 Other - international 242 248 Total $ 2,667 $ 2,542

Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation We are considered a domestic company in the United Kingdom and, as such, are required to comply with filing requirements in the United Kingdom. Additionally, we are not considered a “foreign private issuer” in the U.S.; therefore, we are required to comply with the reporting and other requirements imposed by the U.S. securities law on U.S. domestic issuers, which, among other things, requires reporting under accounting principles generally accepted in the United States of America (“U.S. GAAP”). The consolidated financial statements included in this Form 10-K are prepared in conformity with U.S. GAAP. Our consolidated financial statements include the accounts of all majority-owned subsidiary companies. All intercompany balances and transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the manner and presentation in the current period.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. It is at least reasonably possible that the effect on the financial statements of a change in estimate due to one or more future confirming events could have a material effect on the financial statements.
Foreign Currency	Foreign Currency The U.S. dollar is our reporting currency for our consolidated financial statements in U.S. GAAP. We determine the functional currency of each subsidiary based on a number of factors, including the predominant currency for revenues, expenditures and borrowings. Adjustments from the remeasurement of non-functional currency monetary assets and liabilities are recorded in “Other (expense) income, net” in the Consolidated Statements of Income. When a subsidiary’s functional currency is not the U.S. dollar, translation adjustments resulting from translating the functional currency financial statements into U.S. dollar equivalents are recorded in “Accumulated other comprehensive loss” in the Consolidated Balance Sheets. Translation adjustments on intercompany foreign currency receivables and payables that are not expected to be settled in the foreseeable future are reported in the same manner as translation adjustments.
Revenue Recognition	Revenue Recognition We recognize revenue at a point in time when the customer obtains control of the promised products. For most transactions this occurs when products are shipped from our manufacturing facilities or at a later point when control of the products transfers to the customer at a specified destination or time. All amounts billed to a customer in a sales transaction related to shipping and handling represent revenues earned and are reported as “Net sales” in the Consolidated Statements of Income. Accruals are made for sales returns, rebates and other allowances, which are recorded in “Net sales” in the Consolidated Statements of Income and are based on our historical experience and current business conditions. Additionally, we have elected the practical expedient to
Cost of Goods Sold	Cost of Goods Sold Cost of goods sold includes costs for purchasing, receiving, manufacturing, and distributing products, including raw materials, energy, labor, depreciation, depletion, shipping and handling, freight, warehousing, and other production costs.
Research and Development	Research and Development Research and development costs, included in “Selling, general and administrative expenses” in the Consolidated Statements of Income comprised of salaries, building costs, utilities, administrative expenses, third party research, and allocations of corporate costs, were $12 million, $13 million, and $12 million during 2022, 2021, and 2020, respectively, and were expensed as incurred.
Selling, General and Administrative Expenses	Selling, General and Administrative Expenses Selling, general and administrative expenses include costs related to marketing, research and development, agent commissions, and legal and administrative functions such as corporate management, human resources, information technology, investor relations, accounting, treasury, and tax compliance.
Income Taxes	Income Taxes We use the asset and liability method of accounting for income taxes. The estimation of the amounts of income taxes involves the interpretation of complex tax laws and regulations and how foreign taxes affect domestic taxes, as well as the analysis of the realizability of deferred tax assets, tax audit findings, and uncertain tax positions. Deferred tax assets and liabilities are determined based on temporary differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. A valuation allowance is provided against a deferred tax asset when it is more likely than not that all or some portion of the deferred tax asset will not be realized. We periodically assess the likelihood that we will be able to recover our deferred tax assets and reflect any changes in our estimates in the valuation allowance, with a corresponding adjustment to earnings or other comprehensive income (loss), as appropriate. All available positive and negative evidence is weighted to determine whether a valuation allowance should be recorded.
Earnings Per Share	Earnings per Share Basic and diluted earnings per share are calculated using the two-class method. Under the two-class method, earnings used to determine basic earnings per share are reduced by an amount allocated to participating securities. Participating securities include restricted shares issued under the Tronox Management Equity Incentive Plan (the “MEIP”) (see Note 20), which contains non-forfeitable dividend rights. Our unexercised options and unvested restricted share units do not contain non-forfeitable rights to dividends and, as such, are not considered in the calculation of basic earnings per share. Our unvested restricted shares do not have a contractual obligation to share in losses; therefore, when we record a net loss, none of the loss is allocated to participating securities. Consequently, in periods of net loss, the two-class method does not have an effect on basic loss per share. Diluted earnings per share is calculated by dividing net earnings allocable to ordinary shares by the weighted-average number of ordinary shares outstanding for the period, as adjusted for the potential dilutive effect of non-participating restricted share units and options. The options are included in the calculation of diluted earnings per ordinary share utilizing the treasury stock method. See Note 6.
Fair Value Measurement	Fair Value Measurement We measure fair value on a recurring basis utilizing valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs, to the extent possible, and consider counterparty credit risk in our assessment of fair value. The fair value hierarchy is as follows: • Level 1 – Quoted prices in active markets for identical assets and liabilities; • Level 2 – Quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active or other inputs that are observable or can be corroborated by observable market data; and, • Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities See Note 15.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all investments with original maturities of three months or less to be cash equivalents. We maintain cash and cash equivalents in bank deposit and money market accounts that may exceed federally insured limits. The financial institutions where our cash and cash equivalents are held are generally highly rated and geographically dispersed, and we have a policy to limit the amount of credit exposure with any one institution. We have not experienced any losses in such accounts and believe we are not exposed to significant credit risk.
Accounts Receivable, net of allowance for credit losses	Accounts Receivable, net of allowance for credit losses We perform credit evaluations of our customers, and take actions deemed appropriate to mitigate credit risk. Only in certain specific occasions do we require collateral in the form of bank or parent company guarantees or guarantee payments. We maintain allowances for potential credit losses based on specific customer review and current financial conditions.
Inventories, net	Inventories, net Pigment inventories are stated at the lower of actual cost and net realizable value, net of allowances for obsolete and slow-moving inventory. The cost of inventories is determined using the first-in, first-out method. Carrying values include material costs, labor, and associated indirect manufacturing expenses. Costs for materials and supplies, excluding titanium ore, are determined by average cost to acquire. Feedstock and co-products inventories including titanium ore are stated at the lower of the weighted-average cost of production or market. Inventory costs include those costs directly attributable to products, including all manufacturing overhead but excluding distribution costs. Raw materials are carried at actual cost. We review the cost of our inventory in comparison to its net realizable value. We also periodically review our inventory for obsolescence. In either case, we record any write-down equal to the difference between the cost of inventory and its estimated net realizable value based on assumptions about alternative uses, market conditions and other factors. Inventories expected to be sold or consumed within twelve months after the balance sheet date are classified as current assets and all other inventories are classified as non-current assets. See Note 8.
Long Lived Assets	Long Lived Assets Property, plant and equipment, net is stated at cost less accumulated depreciation, and is depreciated over its estimated useful life using the straight-line method as follows: Land improvements 10 — 20 years Buildings 10 — 40 years Machinery and equipment 3 — 25 years Furniture and fixtures 10 years Maintenance and repairs are expensed as incurred, except for costs of replacements or renewals that improve or extend the lives of existing properties, which are capitalized. Upon retirement or sale, the cost and related accumulated depreciation are removed from the respective account, and any resulting gain or loss is included in “Cost of goods sold” or “Selling, general, and administrative expenses” in the Consolidated Statements of Income. See Note 9. We capitalize costs associated with our asset retirement obligations which are generally included in machinery and equipment. See Note 17. We capitalize interest costs on major projects that require an extended period of time to complete. See Note 13. Mineral property acquisition costs are capitalized as tangible assets when management determines that probable future benefits consisting of a contribution to future cash inflows have been identified and adequate financial resources are available or are expected to be available as required to meet the terms of property acquisition and anticipated exploration and development expenditures. Mineral leaseholds are depleted over their useful lives as determined under the units of production method. Mineral property exploration costs are expensed as incurred. When it has been determined that a mineral property can be economically developed as a result of establishing proven and probable reserves, the costs incurred to develop such property through the commencement of production are capitalized. See Note 10. Intangible assets are stated at cost less accumulated amortization and are amortized on a straight-line basis over their estimated useful lives, which generally range from 3 to 20 years. See Note 11. We evaluate the recoverability of the carrying value of long-lived assets that are held and used whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Under such circumstances, we assess whether the projected undiscounted cash flows of our long-lived assets are sufficient to recover the carrying amount of the asset group being assessed. If the undiscounted projected cash flows are not sufficient, we calculate the impairment amount by discounting the projected cash flows using our weighted-average cost of capital. For assets that satisfy the criteria to be classified as held for sale, an impairment loss, if any, is recognized to the extent the carrying amount exceeds fair value, less cost to sell. The amount of the impairment of long-lived assets is written off against earnings in the period in which the impairment is determined.
Leases	Leases We determine if a contract is or contains a lease at inception of the contract. Our leases are primarily operating leases. Leased assets primarily include office buildings, rail cars and motor vehicles, forklifts, and other machinery and equipment. Our leases primarily have fixed lease payments, with real estate leases typically requiring additional payments for real estate taxes and occupancy-related costs. Certain of our leases also have variable lease payments. Variable lease payments that depend on an index or a rate (such as the Consumer Price Index) are included in our initial measurement of the lease right of use assets and lease liabilities. Variable lease payments that are not index or rate based (such as variable payments based on our performance or use of the leased assets) are recorded as expenses when incurred and excluded from the measurement of right of use assets and lease liabilities. Our leases typically have initial lease terms ranging from 1 to 25 years. Some of our lease agreements include options to renew, extend or early terminate the leases. Lease term is the non-cancellable period of a lease, adjusted by the period covered by an option to extend or terminate the lease if we are reasonably certain to exercise (or not exercise) that option. Our operating leases typically do not contain purchase options we expect to exercise, residual value guarantees or other material covenants. Operating leases are recorded under “Lease right of use assets”, “Short-term lease liabilities”, and “Long-term lease liabilities” on the Consolidated Balance Sheets. Finance leases are recorded under “Property, plant and equipment net”, “Long-term debt due within one year”, and “ Long-term debt
Long-term Debt	Long-term Debt Long-term debt is stated net of unamortized original issue premium or discount. Premiums or discounts are amortized using the effective interest method with amortization expense recorded in “Interest and debt expense, net” in the Consolidated Statements of Income. Deferred debt issuance costs related to a recognized debt liability are presented in the Consolidated Balance Sheets as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts and are amortized using the effective interest method with amortization expense recorded in “Interest and debt expense, net” in the Consolidated Statements of Income. See Note 13.
Asset Retirement Obligations	Asset Retirement ObligationsAsset retirement obligations are recorded at their estimated fair value, and accretion expense is recognized over time as the discounted liability is accreted to its expected settlement value. Fair value is measured using expected future cash outflows discounted at our credit-adjusted risk-free interest rate, which are considered Level 3 inputs. We classify accretion expense related to asset retirement obligations as a production cost, which is included in “Cost of goods sold” in the Consolidated Statements of Income. See Note 17.
Environmental Remediation and Other Contingencies	Environmental Remediation and Other Contingencies We record an undiscounted liability when any of the following occur: 1) a claim or assessment has been asserted, 2) a litigation has commenced, or 3) based on available information, it is probable that a claim or an assessment will be asserted or a litigation will commence; and in addition, the outcome is expected to be unfavorable to us and the associated costs can be reasonably estimated. See Note 18.
Self-Insurance	Self-Insurance We are self-insured for certain levels of general and vehicle liability, property, workers’ compensation and health care coverage. The cost of these self-insurance programs is accrued based upon estimated fully developed settlements for known and anticipated claims. Any resulting adjustments to previously recorded reserves are reflected in current operating results. We do not accrue for general or unspecific business risks.
Share-based Compensation	Share-based Compensation Equity Restricted Share and Restricted Share Unit Awards — The fair value of equity instruments is measured based on the share price on the grant date and is recognized over the vesting period. These awards contain service, market, and/or performance conditions. For awards containing only a service or a market condition, we have elected to recognize compensation costs using the straight-line method over the requisite service period for the entire award. For awards containing a market condition, the fair value of the award is measured using the Monte Carlo simulation under a lattice model approach. For awards containing a performance condition, the fair value is the grant date close price and compensation expense is not recognized until we conclude that it is probable that the performance condition will be met. We reassess the probability at least quarterly. See Note 20.
Defined Benefit Pension and Postretirement Benefit Plans	Defined Benefit Pension and Postretirement Benefit Plans We recognize the funded status of our defined benefit pension plans and postretirement benefit plans in the Consolidated Balance Sheets. The funded status is measured as the difference between the fair value of plan assets and the benefit obligation at the measurement date. The benefit obligation for the defined benefit plans is the projected benefit obligation (PBO), which represents the actuarial present value of benefits expected to be paid upon retirement based on employee services already rendered and estimated future compensation levels. The benefit obligation for our postretirement benefit plans is the accumulated postretirement benefit obligation (APBO), which represents the actuarial present value of postretirement benefits attributed to employee services already rendered. The fair value of plan assets related to our defined benefit plan represents the current market value of assets held in a trust fund, which is established for the sole benefit of plan participants. If the fair value of plan assets exceeds the benefit obligation, the plan is overfunded, and the excess is recorded as a prepaid pension asset. On the other hand, if the benefit obligation exceeds the fair value of plan assets, the plan is underfunded, and the deficit is recorded as pension and postretirement healthcare benefits obligation in the Consolidated Balance Sheet. The portion of the pension and postretirement healthcare obligations payable within the next 12 months is recorded in accrued liabilities in the Consolidated Balance Sheet. Net periodic pension and postretirement benefit cost represents the aggregation of service cost, interest cost, expected return on plan assets, amortization of prior service costs or credits and actuarial gains or losses previously recognized as a component of OCI and it is recorded in the Consolidated Statement of Income. Net periodic cost is recorded in cost of goods sold and selling, general and administrative expenses in the Consolidated Statement of Income based on the employees’ respective functions. Actuarial gains or losses represents the effect of remeasurement on the benefit obligation principally driven by changes in the plan actuarial assumptions. Prior service costs or credits arise from plan amendments. The actuarial gains or losses and prior service costs or credits are initially recognized as a component of Other comprehensive income (loss) in the Consolidated Statement of Comprehensive Income. Those gains or losses and prior service costs or credits are subsequently recognized as a component of net periodic cost. The measurement of benefit obligations and net periodic cost is based on estimates and assumptions approved by management. These valuations reflect the terms of the plans and use participant-specific information such as compensation, age and years of service, as well as certain assumptions, including estimates of discount rates, expected return on plan assets, rate of compensation increases and mortality rates. Defined Contribution Plans — We recognize our contribution as expense when they are due. The expense is recorded in cost of goods sold or selling, general and administrative expenses the Consolidated Statement of Income based on the employees’ respective functions. Multiemployer Plan — We treat our multiemployer plan like a defined contribution plan. A pension plan to which two or more unrelated employers contribute is generally considered to be a multiemployer plan. As a defined contribution plan, we recognize the contribution for the period as a net benefit cost and any contributions due and unpaid as a liability.
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform Financial Reporting”. This amendment is elective in nature. Amongst other aspects, this standard provides for practical expedients and exceptions to current accounting standards that reference a rate which is expected to be dissolved (e.g., London Interbank Offered Rate “LIBOR”) as it relates to hedge accounting, contract modifications and other transactions that reference this rate, subject to meeting certain criteria. The standard is effective for all entities as of March 12, 2020 through December 31, 2022. In December 2022, the FASB issued ASU 2022-06, which defers the sunset date of ASC 848, Reference Rate Reform, from December 31, 2022 to December 31, 2024. ASU 2022-06 is effective immediately for all entities.
