| 1. Summary of Significant Accounting Policies (Policies) | 12 Months Ended |
| Dec. 31, 2020 |
| Accounting Policies [Abstract] | |
| Nature of Operations | 1.1 Nature of Operations Sincerity Applied Material Holdings Corp (the
"Company'') is a specialized provider of technologically advanced packing materials for the automotive, packaging, building &
construction, and engineering industries, with headquarters located near Melbourne, Australia. The Company's primary customer is an unrelated
entity with global operations that accounts for approximately 80% - 90% of The Company's revenue, and The Company's primary suppliers
are in China and Malaysia. |
| Basis of Accounting | 1.2 Basis of Accounting The accompanying financial statements include
the accounts of Sincerity Applied Material Holdings Corp which is a company domiciled in Australia. These financial statements have been
prepared in accordance with the accounting principles generally accepted in the United States (“GAAP”) and Regulation S-X
published by the US Securities and Exchange Commission (the “SEC”). Certain prior period amounts have been reclassified to
conform to the current period presentation. Such reclassifications had no effect on the prior period net income, accumulated deficit,
net assets, or total shareholders' deficit. The Company has evaluated events or transactions through the date of issuance of this report
in conjunction with the preparation of these consolidated financial statements. All amounts presented are in US dollars, unless otherwise
noted. The financial statements, except for cash
flow information, have been prepared on an accruals basis and are based on historical costs, modified, where applicable, by the measurement
at fair value of selected non-current assets, financial assets and financial liabilities. The amounts presented in the financial statements
have been rounded to the nearest dollar. |
| Going Concern Basis | 1.3 Going Concern Basis The financial statements have been prepared
on the going concern basis, which assumes continuity of normal business activities and the realization of assets and the settlement of
liabilities in the ordinary course of business. At December 31, 2020, the Company had a current
asset deficiency of $40,846 (December 31, 2019 current asset deficiency of $99,743) and reported an after tax income of $85,582 for the
year (2019 loss: $11,690). Despite the current asset deficiency, the
company has prepared the financial statements on a going concern basis that contemplates the continuity of normal business activity, realization
of assets and settlement of liabilities at the amounts recorded in the financial statements in the ordinary course of business. The company believes that there are reasonable
grounds to support the fact that it will be able to pay its debts as and when they become due and payable. In forming this opinion, the
Group has considered the following factors:
(i) The company has the ability to raise fund through private placements and convertible notes;
(ii) The company has been streamlining its operation by reducing operation costs; and
(iii) Applying for financial assistance from the Australian Government available for businesses impacted by COVID-19 If the Company is unable to continue as a
going concern it may be required to realize its assets and extinguish its liabilities other than in the ordinary course of business at
amounts different from those stated in the financial statements. The financial statements do not include adjustments
relating to the recoverability and classification of recorded asset amounts or to the amounts and classification of liabilities that might
be necessary should the Company not continue as a going concern. |
| Use of Estimates | 1.4 Use of Estimates The preparation of financial statements in
conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP’’) requires management
to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities
at the date of the financial statements and reported amounts of revenue and expenses during the reporting period. Actual results could
differ from those estimates. |
| Foreign Currency Translation | 1.5 Foreign Currency Translation The functional currency of the Company is
its local currency, the Australian dollar (AUD). The financial statements of the Company have been translated into U.S. dollars (USD).
All balance sheet accounts, other than those in stockholder's deficiency, which are translated, based on historical rates accumulated
over time, have been translated using the exchange rate in effect at the balance sheet date. Income statement amounts have been translated
using the average exchange rate in effect for the year ended December 31, 2020. Accumulated net translation adjustments have been reported
separately in other comprehensive loss in the financial statements. Foreign currency translation adjustments resulted in a loss of $35,438
for the year ended December 31, 2020; such translation adjustments are not subject to income taxes. Foreign currency transaction gain
resulting from exchange rate fluctuations on transactions denominated in a currency other than the AUD, the functional currency, totaled
$4,144 for the year ended December 31, 2020, and is included in the accompanying statement of income for the period. |
| Cash and Cash Equivalents and Concentration of Credit Risk | 1.6 Cash and Cash Equivalents and Concentration of Credit Risk The Company considers all highly liquid short
term investments with original maturities of three months or less at the date of acquisition to be cash equivalents. The carrying value
of cash and cash equivalents approximates fair value due to the short term nature of these instruments. The Company's financial instruments exposed
to concentrations of credit risk consist primarily of cash and cash equivalents. Cash and cash equivalents are held in several Australian
bank accounts. The Company regularly assesses the level of credit risk we are exposed to and whether there are better ways of managing
credit risk. The Company invests its cash and cash equivalents with reputable financial institutions. The Company has not incurred any
losses related to these deposits. |
| Accounts Receivable | 1.7 Accounts Receivable The Company carries its accounts receivable
at cost less an allowance for doubtful accounts. The Company evaluates its accounts receivable on a regular basis and establishes an allowance
for doubtful accounts, when deemed necessary, based on a history of past write- offs and collections and current credit conditions. A
receivable is considered past-due based either on contractual terms or payment history. Accounts are written off as uncollectible after
collection efforts have failed. In addition, The Company does not generally charge interest on past-due accounts or require collateral.
It is at least reasonably possible that changes may occur in the near term that would affect management’s estimate of the allowance
for doubtful accounts. At December 31, 2020, management determined that no allowance for doubtful accounts was required. |
| Property and Equipment | 1.8 Property and Equipment Property and equipment are recorded at cost.
Costs of renewal and improvements that substantially extend the useful lives of assets are capitalized. Maintenance and repair costs are
expensed when incurred. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, generally
five years. Derecognition An item of plant and equipment is derecognized
upon disposal or when no further economic benefits are expected from its use or disposal. |
| Payables | 1.9 Payables Payables are carried at amortized cost and,
due to their short-term nature, they are not discounted. They represent liabilities for goods and services provided to the Company prior
to the end of the financial period that are unpaid and arise when the Company becomes obliged to make future payments in respect of the
purchase of these goods and services. The amounts are unsecured and are usually paid within 30 days of recognition. |
| Provisions | 1.10 Provisions Provisions are recognized when the Company
has a legal or constructive obligation, as a result of past events, for which it is probable that an outflow of economic benefits will
result and that outflow can be reliably measured. Provisions are measured using the best estimate of the amounts required to settle the
obligation at the end of the reporting period. |
| Leases | 1.11 Leases Leases of fixed assets, where substantially
all the risks and benefits incidental to the ownership of the asset – but not the legal ownership – are transferred to entities
in the consolidated group, are classified as finance leases. Finance leases are capitalized by recognizing
an asset and a liability at the lower of the amounts equal to the fair value of the leased property or the present value of the minimum
lease payments, including any guaranteed residual values. Lease payments are allocated between the reduction of the lease liability and
the lease interest expense for the period. Leased assets are depreciated on a straight-line
basis over the shorter of their estimated useful lives or the lease term. Lease payments for operating leases, where
substantially all the risks and benefits remain with the lessor, are recognized as expenses on a straight-line basis over the lease term. |
| Loans and Borrowings | 1.12 Loans and Borrowings All loans and borrowings are initially recognized
at cost, being the fair value of the consideration received net of issue costs associated with the borrowing. After initial recognition, interest-bearing
loans and borrowings are subsequently measured at amortized cost using the effective interest method. Amortized cost is calculated by
taking into account any issue costs, and any discount or premium on settlement. |
| Revenue Recognition | 1.13 Revenue Recognition The Company recognizes revenue when the goods
are delivered at the port of shipment by the supplier, the price is fixed or determinable, and collectability is reasonably assured. Interest revenue is recognized using the effective
interest method, which for floating rate financial assets is the rate inherent in the instrument. All revenue is stated net of the amount of
goods and services tax. |
| Income Tax | 1.14 Income Tax We account for income taxes using the asset
and liability method, under which the current income tax expense or benefit is the amount of income tax expected to be payable or refundable
in the current year. Deferred tax assets and liabilities are recorded for the estimated future tax consequences of temporary differences
between the financial statement carrying amounts of assets and liabilities and their respective tax bases, and for operating loss and
tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income
in the year in which the temporary differences are expected to be recovered or settled. We evaluate the realizability of our deferred
tax assets and establish a valuation allowance when it is more likely than not that all or a portion of our deferred tax assets will not
be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing
taxable temporary differences, projected future taxable income, tax planning strategies, and results of recent operations. If we determine
that we would be able to realize our deferred tax assets in the future in excess of their net recorded amount, we would make an adjustment
to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. We account for the uncertainty in income tax
components based on tax positions taken or expected to be taken in a tax return. To recognize a benefit, a tax position must be more likely
than not to be sustained upon examination by taxing authorities. We do not recognize tax benefits that have a less than 50 percent likelihood
of being sustained. Our policy is to recognize interest and tax penalties related to unrecognized tax benefits in income tax expense;
no interest or tax penalties on uncertain tax benefits have been recorded through December 31, 2020. |
| Goods and Services Tax (GST) | 1.15 Goods and Services Tax (GST) Revenues, expenses and assets are recognized
net of the amount of GST, except where the amount of GST incurred is not recoverable from the Australian Taxation Office (ATO). Receivables and payables are stated inclusive
of the amount of GST receivable or payable. The net amount of GST recoverable from, or payable to, the ATO is included with other receivables
or payables in the statement of financial position. Cash flows are presented on a gross basis.
The GST components of cash flows arising from investing or financing activities, which are recoverable from or payable to the ATO, are
presented as operating cash flows included in receipts from customers or payments to suppliers. |
| Impairment of Long-Lived Assets | 1.16 Impairment of Long-Lived Assets The Company reviews long-lived assets, including
fixed assets, for impairment whenever events or circumstances indicate that the carrying value of such assets may not be fully recoverable.
Impairment is present when the sum of undiscounted estimated future cash flows expected to result from use of the asset is less than carrying
value. If impairment is present, the carrying value of the impaired asset is reduced to its fair value. Fair value is determined based
on discounted cash flows or appraised values, depending on the nature of the asset. During year ended December 31, 2020, no impairment
losses were recognized for long-lived assets. |
| Stock-Based Compensation | 1.17 Stock-Based Compensation The Company recognizes all employee share-based
compensation as a cost in the consolidated financial statements. Equity-classified awards principally related to stock options, restricted
stock units (“RSUs”) and performance stock units (“PSU”), are measured at the grant date fair value of the award.
The Company determines grant date fair value of stock option awards using the Black-Scholes option-pricing model. The fair value of restricted
stock awards is determined using the closing price of the Company’s common stock on the grant date. For service based vesting grants,
expense is recognized over the requisite service period based on the number of options or shares expected to ultimately vest. For performance
based vesting grants, expense is recognized over the requisite period until the performance obligation is met, assuming that it is probable.
No expense is recognized for performance-based grants until it is probable the vesting criteria will be satisfied. Forfeitures are estimated
at the date of grant and revised when actual or expected forfeiture activity differs materially from original estimates. Stock-based payments to non-employees are
re-measured at each reporting date and recognized as services are rendered, generally on a straight-line basis. The Company believes that
the fair values of these awards are more reliably measurable than the fair values of the services rendered. |
| Earnings (Loss) per Common Share | 1.18 Earnings (Loss) per Common Share Basic earnings (loss) per common share is
computed by dividing income or losses available to common shareholders by the weighted average number of common shares outstanding for
the period. Diluted earnings (loss) per common share is computed similar to basic net income or losses per share except that the denominator
is increased to include the number of additional common shares that would have been outstanding if all the potential common shares, warrants
and stock options had been issued and of the additional common shares were dilutive. Diluted earnings (loss) per common share is based
on the assumption that all dilutive convertible shares and stock options were converted or exercised. Dilution is computed by applying
the treasury stock method for the outstanding options and the if-converted method for the outstanding convertible preferred shares. Under
the treasury stock method, options and warrants are assumed to be exercised at the beginning of the period (or at the time of issuance,
if later), and as if funds obtained thereby were used to purchase common stock at the average market price during the period. Under if
–converted method, convertible outstanding instruments are assumed to be converted into common stock at the beginning of the period
(or at the time of issuance, if later). |
| Accumulated Other Comprehensive Income (Loss) | 1.19 Accumulated Other Comprehensive Income (Loss) Comprehensive income (loss) is presented net
of applicable income taxes in the accompanying consolidated statements of stockholders' equity and comprehensive income (loss). Other
comprehensive income (loss) is comprised of revenues, expenses, gains, and losses that under GAAP are reported as separate components
of stockholders' equity instead of net income (loss). |
| Recently Issued Accounting Standards | 1.20 Recently Issued Accounting Standards The Company continually assesses any new accounting
pronouncements to determine their applicability to the Company. Where it is determined that a new accounting pronouncement affects the
Company’s financial reporting, the Company undertakes a study to determine the consequence of the change to its financial statements
and assures that there are proper controls in place to ascertain that the Company’s financials properly reflect the change. The
Company currently does not have any recent accounting pronouncements that they are studying and feel may be applicable. |
| Reverse Acquisition Accounting | 1.21 Reverse Acquisition Accounting In accordance with “reverse acquisition”
accounting treatment, our historical financial statements as of period ends, and for periods ended, prior to the Acquisition will be replaced
with the historical financial statements of Sincerity Australia Pty Ltd (“SAPL”), prior to the Acquisition, in all future
filings with the SEC. Consequently retroactive adjustments have been made to the equity balances of SAPL to reflect the equity balances
of the legal parent company Sincerity Applied Materials Holdings Corp as required under ASC 805 and the application of reverse acquisition
accounting. |
| COVID-19 | 1.22 COVID-19 The outbreak of the novel strain of
coronavirus (“COVID-19”) and the ongoing pandemic, has resulted in governments worldwide enacting various emergency measures
to combat the spread of the virus. These measures, which include the implementation of travel bans, border shutdowns, self-imposed quarantine
periods, closing of non-essential businesses and social distancing, have caused material disruption to businesses globally resulting in
an economic slowdown. In addition, global equity markets have experienced significant volatility and weakness. Governments and central
banks have reacted with significant monetary and fiscal interventions designed to stabilize economic conditions. |
