Notes to Financial Statements
Nature of Operations [Text Block]	1. The Company Alpha Pro Tech, Ltd. (“Alpha Pro Tech,” the “Company,” “we”, “us” or “our”) is in the business of protecting people, products and environments. The Company accomplishes this by developing, manufacturing and marketing a line of building supply products for the new home and re-roofing markets and a line of disposable protective apparel for the cleanroom, industrial, pharmaceutical, medical and dental markets. The Building Supply segment consists of construction weatherization products, such as housewrap, housewrap accessories, namely tape and flashing, and synthetic roof underlayment, as well as other woven material. The Disposable Protective Apparel segment consists of a complete line of disposable protective garments (shoecovers, bouffant caps, coveralls, gowns, frocks and lab coats), face masks and face shields. All of our disposable protective apparel products, including face masks and face shields, are sold through similar distribution channels, are single-use and disposable, have the purpose of protecting people, products and environments, and have to be produced in Food and Drug Administration (“FDA”) approved facilities, regardless of the market served. The Company’s products are sold under the "Alpha Pro Tech" brand name as well as under private label, and are predominantly sold in the United States of America (“U.S.”). The novel coronavirus (COVID-19) pandemic has adversely affected global economies, financial markets and the overall environment in which we do business. Overall, the increase in sales of our Disposable Protective Apparel segment products resulting from the pandemic has had a positive impact on our year-to-date results, but the positive impact in 2022 is less than in 2021, as the effects of COVID-19 are normalizing. The extent of the pandemic’s effect on our future operational and financial performance will depend in large part on future developments, which cannot be predicted with confidence at this time. Future developments include the duration, scope and severity of the pandemic and new variants, including the Omicron variant, the actions taken to contain or mitigate its impact, the impact on governmental programs and budgets, the development of treatments or vaccines, and the efficacy of mass vaccinations, and the resumption of widespread economic activity in certain sectors. We are unable to predict with any certainty the likely impact of any future pandemics on our future operations.

Notes to Financial Statements
Error Correction [Text Block]	2. Revised Prior Period Financial Statements During the financial close for the fiscal year ended December 31, 2022, the Company discovered certain errors related to foreign currency translation in relation to our unconsolidated affiliate operations in India. In periods prior to January 1, 2021, the Company should have recognized approximately $773,000 loss in accumulated other comprehensive income (“AOCI”) related to changes in foreign currency exchange rates as our unconsolidated affiliate operation are in India. For the year ended December 31, 2021, the Company should have recognized an additional loss of approximately $96,000 for a total loss in AOCI of approximately $869,000. As a result, the Company adjusted its value in equity investment in unconsolidated affiliate in total assets and accumulated other comprehensive loss (“AOCL”) in shareholders’ equity on the balance sheet, and on the consolidated statements of shareholder’s equity. As the resulting foreign currency translation gains or losses are deferred as AOCL and reclassified to earnings only upon sale or liquidation of that business, the Company has included the adjustments in the consolidated statements of comprehensive income (loss). There was no impact on retained earnings because, as stated above, the effect on earnings is only recorded upon sale or liquidation of our unconsolidated affiliate. These revisions resulted in a decrease in equity investment of unconsolidated affiliate, an increase in accumulated other comprehensive loss and a decrease in total shareholders’ equity, but no effect on net income, earnings per share or cash flows. Management has determined that this revision was not material on a quantitative or qualitative basis to the prior period financial statements based on our analysis performed in accordance with the guidance provided by SEC Staff Accounting Bulletins No. 99 – Materiality and No. 108 – Considering the Effects of Prior Year Misstatements. However, management has determined that the cumulative effect of the errors was material on the current year balance sheet. As discussed at Note 7, the Company owns an equity investment in an unconsolidated affiliate that is based in India. U.S. generally accepted accounting principles (“U.S. GAAP”) requires that the investment be adjusted each period to reflect changes in its value in dollars due to fluctuation in the exchange rate with the Indian rupee, with an offsetting entry to other comprehensive loss. Since the inception of the investment in 2005 through 2021, these required adjustments erroneously were not recorded. The Company has determined that the impact of adjustments relating to the corrections of this accounting error is not material to previously issued annual audited and unaudited financial statements and as such no restatement was necessary. Correcting prior year financial statements for immaterial errors would not require previously filed reports to be amended. Such correction may be made the next time the registrant files the prior year financial statements. However, correcting the cumulative error in the current year would be material to the current year.

Notes to Financial Statements
Significant Accounting Policies [Text Block]	3. Summary of Significant Accounting Policies Principles of Consolidation The consolidated financial statements of the Company include the accounts of the Company and its wholly-owned subsidiaries, Alpha Pro Tech, Inc. and Alpha ProTech Engineered Products, Inc. All significant intercompany accounts and transactions have been eliminated in consolidation. Events that occurred after December 31, 2022 through the date on which these financial statements were filed with the Securities and Exchange Commission (“SEC”) were considered in the preparation of these financial statements. 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 and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses for the reporting period. Actual results could differ from these estimates. Periods Presented All amounts have been rounded to the nearest thousand with the exception of the per share data. The Company qualified as a smaller reporting company at the measurement date for determining such qualification during 2022. According to the disclosure requirements for smaller reporting companies, the Company has included balance sheets as of the end of the two most recent years and statements of income, comprehensive income, shareholders’ equity and cash flows for each of the two most recent years. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Investments Investments are classified as available-for-sale in accordance with U.S. GAAP. The Company does not have any investments in securities that are classified as held-to-maturity or trading. Available-for-sale investments are carried at their fair values using quoted prices in active markets for identical securities, with realized and unrealized gains and losses reported in net income. The cost of securities sold is based on the specific identification method. Investments that the Company intends to hold for more than one year are classified as long-term investments in the accompanying consolidated balance sheets. Accounts Receivable Accounts receivable are recorded at the invoice amount and do not bear interest. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable; however, changes in circumstances relating to accounts receivable may result in a requirement for additional allowances in the future. The Company determines the allowance based upon historical write-off experience and known conditions about its customers’ current ability to pay. Account balances are charged against the allowance when management determines that the probability for collection is remote. Inventories Inventories include freight-in, materials, labor and overhead costs and are stated at the lower of cost or net realizable value. Allowances are recorded for slow-moving, obsolete or unusable inventories. The Company assesses inventories for estimated obsolescence or unmarketable products and writes down the difference between the cost of the inventories and the estimated net realizable values based upon assumptions about future sales and supplies on-hand. Property and Equipment Property and equipment are stated at cost less accumulated depreciation and amortization. Costs to develop internal use software are charged to expense as incurred until the preliminary project stage has been completed and application development begins. The Company discontinues capitalization upon entering the post-implementation stage and expenses ongoing maintenance and support costs. Property and equipment are depreciated or amortized using the straight-line method over the shorter of the respective useful lives of the assets or the related lease terms as follows: Buildings (in years) 25 Machinery and equipment (in years) 5 - 15 Office furniture and equipment (in years) 2 - 7 Leasehold improvements (in years) 4 - 5 Software (in years) 5 Expenditures for renewals and betterments are capitalized, whereas costs of maintenance and repairs are charged to operations in the period incurred. Goodwill and Intangible Assets The Company accounts for goodwill and definite-lived intangible assets in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 350, Intangibles – Goodwill and Other. Goodwill is not amortized, but rather is tested annually for impairment. Intangible assets with finite lives are amortized over their useful lives (see Note 6). The Company’s patents and trademarks are recorded at cost and are amortized using the straight-line method over their estimated useful lives of 5-17 years. Fair Value of Financial Instruments The estimated fair values of financial instruments are determined based on relevant market information and cannot be determined with precision. The Company’s financial instruments consist primarily of cash, cash equivalents and marketable securities. The Company’s marketable securities are classified as available-for-sale and are carried at fair market value based on quoted market prices. Impairment of Long-Lived Assets The Company reviews long-lived assets for impairment whenever events or changes in its business circumstances indicate that the carrying amounts of the assets may not be fully recoverable. If it is determined that the undiscounted future net cash flows are not sufficient to recover the carrying values of the assets, an impairment loss is recognized for the excess of the carrying values over the fair values of the assets. The Company believes that the future undiscounted net cash flows to be received from its long-lived assets exceed the assets’ carrying values and, accordingly, the Company has not recognized any impairment losses for the years ended December 31, 2022 and 2021. Revenue Recognition Net sales includes revenue from products and shipping and handling charges, net of estimates for product returns and any related sales incentives. Our customer contracts have a single performance obligation: transfer control of products to customers. Revenue is measured as the amount of consideration that we expect to receive in exchange for transferring control of products. All revenue is recognized when we satisfy our performance obligations under the applicable contract. We recognize revenue in connection with transferring control of the promised products to the customer, with revenue being recognized at the point in time when the customer obtains control of the products, which is generally when title passes to the customer upon delivery to a third party carrier for FOB shipping point arrangements and to the customer for FOB destination arrangements, at which time a receivable is created for the invoice sent to the customer. Shipping and handling activities are performed prior to the customer obtaining control of the goods, and are accounted for as fulfillment activities and are not a promised good or service. Shipping and handling charges billed to customers are included in revenue. Shipping and handling costs, associated with the distribution of the Company’s product to the customers, are recorded in cost of goods sold and are recognized when control of the product is transferred to the customer, which is generally when title passes to the customer upon delivery to a third party carrier for FOB shipping point arrangements and to the customer for FOB destination arrangements. We estimate product returns based on historical return rates and estimate rebates based on contractual agreements. Using probability assessments, we estimate sales incentives expected to be paid over the term of the contract. Sales taxes and value added taxes in foreign and domestic jurisdictions that are collected from customers and remitted to governmental authorities are accounted for on a net basis and, therefore, are excluded from net sales. The Company manufactures certain private label goods for customers and has determined that control does not pass to the customer at the time of manufacture, based upon the nature of the private labelling. The Company has determined as of December 31, 2022 that it had no material contract assets, and concluded that its contract liabilities (primarily rebates) had the right of offset against customer receivables. See Note 15 of these Notes to Consolidated Financial Statements for information on revenue disaggregated by type and by geographic region. Shipping and Handling Costs The costs of shipping products to distributors are recorded in cost of goods sold. Stock-Based Compensation The Company maintains the 2020 Incentive Plan under which the Company may grant incentive stock options, non-qualified stock options, restricted stock, restricted stock units and other equity-based compensation to employees and non-employee directors. Stock options have been granted with exercise prices at or above the fair market value of the underlying shares of common stock on the date of grant. Options vest and expire according to terms established at the grant date. Restricted stock and restricted stock units have been granted, and the fair market value of these awards equals the closing stock price on the date of grant. The Company accounts for share-based awards in accordance with ASC 718, Stock Compensation. ASC 718 requires companies to record compensation expense for the value of all outstanding and unvested share-based awards, including employee stock options. For the years ended December 31, 2022 and 2021, there were 19,600 and zero Income Taxes The Company accounts for income taxes using the asset and liability method. A valuation allowance is recorded to reduce the carrying amounts of deferred income tax assets unless it is more likely than not that such assets will be realized. The Company’s policy is to record any interest and penalties assessed by the Internal Revenue Service as a component of the provision for income taxes. The Company provides allowances for uncertain income tax positions when it is more likely than not that the position will not be sustained upon examination by the tax authority. Alpha Pro Tech, Ltd. and its subsidiaries file income tax returns in the U.S. federal jurisdiction, and in various state and foreign jurisdictions. Earnings Per Common Share The following table provides a reconciliation of both net income and the number of shares used in the computation of “basic” earnings per common share (“EPS”), which utilizes the weighted average number of common shares outstanding without regard to potential common shares, and “diluted” EPS, which includes all potential common shares which are dilutive for the years ended December 31, 2022 and 2021. Years Ended December 31, 2022 2021 Net income (numerator) $ 3,282,000 $ 6,756,000 Shares (denominator): Basic weighted average common shares outstanding 12,713,533 13,225,628 Add: Dilutive effect of common stock options 67,471 273,814 Diluted weighted average common shares outstanding 12,781,004 13,499,442 Earnings per common share: Basic $ 0.26 $ 0.51 Diluted $ 0.26 $ 0.50 Translation of Foreign Currencies Transactions in foreign currencies are translated into U.S. dollars at the exchange rate prevailing at the transaction date. Monetary assets and liabilities in foreign currencies at each period end are translated at the exchange rate in effect at that date. Transaction gains or losses on foreign currencies are reflected in selling, general and administrative expenses and were not material for the years ended December 31, 2022 and 2021. The Company does not have a material foreign currency exposure in regards to purchase agreements with companies in Asia and Mexico as the agreements are in U.S. dollars. In addition, all sales transactions are in U.S. dollars. The Company has a foreign currency exposure with respect to its Canadian branch office. The foreign currency exposure is not material due to the fact that the Company does not manufacture products in Canada. The exposure primarily relates to payroll expenses in the Company’s administrative branch office in Canada. The Company also has potentially material foreign currency exposure in regards to its equity in its unconsolidated affiliate in India. The Company’s unconsolidated affiliate operations are in India; therefore, U.S. GAAP requires the Company to adjust the value of its investment for changes in foreign currency exchange rates. The Company determines the functional currency of its joint venture based upon the primary currency used to generate and expend cash, which is the currency of the country in which the joint venture is located. For joint ventures with functional currencies other than the U.S. dollar, the investment in that joint venture is translated into U.S. dollars using period-end exchange rates. The resulting foreign currency translation losses are deferred as AOCL and reclassified to earnings only upon sale or liquidation of that business. The foreign currency translations reduced the equity in unconsolidated affiliated by $1,489,000 and $869,000 as of December 31, 2022 and 2021, respectively, and the loss was recorded in AOCL. Research and Development Costs Research and development costs are expensed as incurred and are included in selling, general and administrative expenses. Such costs were not material for the years ended December 31, 2022 and 2021. Advertising Costs The Company expenses advertising and promotional costs as incurred. These costs are included in selling, general and administrative expenses and were $102,000 and $27,000 for the years ended December 31, 2022 and 2021, respectively. Loss Contingencies The outcomes of legal proceedings and claims brought against the Company are subject to uncertainty. An estimated loss from a loss contingency such as a legal proceeding or claim is accrued if it is probable that an asset has been impaired or a liability has been incurred and the amount of the loss can be reasonably estimated. In determining whether a loss should be accrued, we evaluate, among other factors, the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss. Fair Value Measurements ASC 820, Fair Value Measurements and Disclosures, establishes a framework for measuring fair value in accordance with U.S. GAAP, clarifies the definition of fair value within that framework and expands disclosures about the use of fair value measurements. On a quarterly basis, the Company measures at fair value certain financial assets using a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s own assumptions. The following fair value hierarchy prioritizes the inputs into three broad levels. This hierarchy requires the Company to minimize the use of unobservable inputs and to use observable market data, if available, when determining fair value. There were no fair values of the Company’s financial assets as of December 31, 2022 and 2021. New Accounting Standards Management periodically reviews new accounting standards that are issued. Management has not identified any new standards that it believes merit further discussion at this time.

Equity Method Investments and Joint Ventures Disclosure [Text Block]	7. Equity Investments in Unconsolidated Affiliate In 2005, Alpha ProTech Engineered Products, Inc. (a subsidiary of Alpha Pro Tech, Ltd.) entered into a joint venture with a manufacturer in India, Maple Industries and associates, for the production of building products. Under the terms of the joint venture agreement, a private company, Harmony Plastics Private Limited (“Harmony”), was created with ownership interests of 41.66% owned by Alpha ProTech Engineered Products, Inc. and 58.34% owned by Maple Industries and associates. This joint venture positions Alpha ProTech Engineered Products, Inc. to respond to current and expected increased product demand for housewrap and synthetic roof underlayment and provides future capacity for sales of specialty roofing component products and custom products for industrial applications requiring high quality extrusion coated fabrics. In addition, the joint venture now supplies products for the Company’s Disposable Protective Apparel segment. The capital from the initial funding and a bank loan, which loan is guaranteed exclusively by the individual shareholders of Maple Industries and associates and collateralized by the assets of Harmony, were utilized to purchase the original manufacturing facility in India. Harmony currently has four three one In accordance with ASC 810, Consolidation, the Company assesses whether or not related entities are variable interest entities (“VIEs”). For those related entities that qualify as VIEs, ASC 810 requires the Company to determine whether the Company is the primary beneficiary of the VIE, and, if so, to consolidate the VIE. The Company has determined that Harmony is not a VIE and is, therefore, considered to be an unconsolidated affiliate. The Company records its investment in Harmony as “equity investment in unconsolidated affiliate” in the accompanying consolidated balance sheets. The Company records its equity interest in Harmony’s results of operations as “equity in income of unconsolidated affiliate” in the accompanying consolidated statements of income. The Company periodically reviews its investment in Harmony for impairment. Management has determined that no impairment was required as of December 31, 2022 or December 31, 2021. Under the equity method, since the Company’s reporting currency is different from of Harmony’s reporting currency, the Company is required to translate our proportionate share of equity for effects of translations in foreign currency and adjust the investment accordingly, and accrue the adjustment as a component of AOCI. For the years ended December 31, 2022 and 2021, the Company purchased $22,877,000 and $26,252,000 of inventories, respectively, from Harmony. For the years ended December 31, 2022 and 2021, the Company recorded equity in income of unconsolidated affiliate of $87,000 and $571,000, respectively. For the years ended December 31, 2022 and 2021, the Company sold $570,000 and $1,931,000 of inventories, respectively, to Harmony. As of December 31, 2022, the Company’s investment in Harmony was $4,718,000, which consisted of its original $1,450,000 investment and cumulative equity in income of unconsolidated affiliate of $5,776,000, less $942,000 in repayments of an advance, payments of $77,000 in dividends and AOCL on foreign currency translations of $1,489,000.

Option Activity The 2004 Stock Option Plan (the “2004 Plan”) is an equity compensation plan that provides for grants of stock options to eligible individuals. The 2004 Plan is intended to recognize the contributions made to the Company by key employees of the Company, provide key employees with additional incentive to devote themselves to the future success of the Company and improve the ability of the Company to attract, retain and motivate individuals. The 2004 Plan also is intended as an incentive to certain members of the Board of Directors of the Company to continue to serve on the Board of Directors and to devote themselves to the future success of the Company. The 2004 Plan provides for a total of 5,000,000 common shares eligible for issuance. Under the 2004 Plan, approximately 5,009,750 options had been granted as of December 31, 2020. Under the 2004 Plan, option grants have a three-year fifth At the Company’s 2020 Annual Meeting of Shareholders held on June 9, 2020, the Company’s shareholders approved the Alpha Pro Tech, Ltd. 2020 Omnibus Incentive Plan (the “2020 Incentive Plan”). The 2020 Incentive Plan provides for the grant of incentive and nonqualified stock options, stock appreciation rights, awards of restricted stock and restricted stock units, performance share awards, cash awards and other equity-based awards to employees (including officers), consultants and non-employee directors of the Company and its affiliates. A total of 1,800,000 shares of the Company’s common stock are reserved for issuance under the 2020 Incentive Plan, plus the number of shares underlying any award granted under the 2004 Option Plan that expires, terminates or is cancelled or forfeited under the terms of the 2004 Option Plan. As a result of the approval of the 2020 Incentive Plan, no future equity awards will be made pursuant to the 2004 Option Plan. Although no new awards may be granted under the 2004 Option Plan, all previously granted awards under the 2004 Option Plan will continue to be governed by the terms of the 2004 Option Plan. During the years ended December 31, 2022 and 2021, 21,772 and 15,140 restricted stock awards were granted under the 2020 Incentive Plan, respectively. The Company recognized $104,000 and $131,000 in compensation expense associated with outstanding restricted stock awards for the year ended December 31, 2022 and 2021, respectively. As of December 31, 2022, $63,000 of total unrecognized compensation cost related to the restricted stock grants was expected to be recognized over a weighted-average remainder period of 0.87 years.

Dividends The holders of the Company’s common stock are entitled to receive such dividends as may be declared by the Board of Directors of the Company from time to time to the extent that funds are legally available for payment thereof. The Company has never declared or paid any dividends on any of its outstanding shares of common stock. The Board of Directors’ current policy is not to pay dividends but rather to use available funds to repurchase common shares in accordance with the Company’s repurchase program and to fund the continued development and growth of the Company.

Concentration Risk Disclosure [Text Block]	16. Concentration of Risk The Company maintains its cash and cash equivalents in various bank accounts, the balances of which at times may exceed federally insured limits. The Company has not experienced any losses related to these accounts, and management does not believe that the Company is exposed to significant credit risk. Management believes that adequate provision has been made for risk of loss on all credit transactions. The Company buys a significant amount of its disposable protective apparel products from a limited number of contract manufacturers located in Asia and, to a much lesser extent, a contract manufacturer in Mexico. Management believes that other suppliers could provide similar products at comparable terms. A change in suppliers, however, could cause a delay in shipment and a possible loss of sales, which would affect operating results adversely. The Building Supply segment buys semi-finished housewrap and synthetic roof underlayment from its joint venture, Harmony, located in India. Although there are a limited number of manufacturers of the particular product, management believes that other suppliers could provide similar products at comparable terms. A change in suppliers, however, could cause a delay in shipment and a possible loss of sales, which would affect operating results adversely. The Company provides products to customers located primarily in the United States. Customers accounting for 10% or more of accounts receivable as of December 31, 2022 and 2021, and 10% or more of net sales for the years ended December 31, 2022 and 2021, were as follows: December 31, 2022 2021 Accounts Receivable: Customer A 47 % 13 % Customer B * 19 % Customer C 17 % * Net sales: Customer A 20 % 21 % Customer B 15 % 13 % Customer C 10 % * *
