Notes to Financial Statements
Significant Accounting Policies [Text Block]	2. Basis of Presentation and Revenue Recognition Policy The interim financial information included in this report is unaudited; however, the information reflects all adjustments (consisting of normal recurring adjustments) that are, in the opinion of management, necessary for the fair presentation of the consolidated financial position, results of operations and cash flows for the interim periods reflected herein. These interim condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) and, therefore, omit certain information and note disclosures that would be necessary to present the statements in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). The interim condensed consolidated financial statements should be read in conjunction with the Company’s current year SEC filings, as well as the Company’s consolidated financial statements for the year ended December 31, 2022, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 (the “2022 Form 10-K”), filed with the SEC on March 16, 2023. The results of operations for the three and nine months ended September 30, 2023 in this Quarterly Report on Form 10-Q are not necessarily indicative of the results to be expected for the full year. The condensed consolidated balance sheet as of December 31, 2022 was prepared using information from the audited consolidated balance sheet contained in the 2022 Form 10-K; however, it does not include all disclosures required by U.S. GAAP for annual consolidated financial statements. Net sales include 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 labeling. The Company has determined as of September 30, 2023 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 10 and Note 11 of these Notes to Condensed Consolidated Financial Statements (Unaudited) for information on revenue disaggregated by type and by geographic region.

Note 3 - Stock-based Compensati

Note 3 - Stock-based Compensation	9 Months Ended

Notes to Financial Statements
Share-Based Payment Arrangement [Text Block]	3. Stock-Based Compensation The Company previously granted stock options to employees and non-employee directors under a stock option plan (the “2004 Option Plan”). 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. The 2004 Option Plan provided for a total of 5,000,000 common shares eligible for issuance. Under the 2004 Option Plan, approximately 5,009,750 options (taking into account cancelled and expired options that were added back to the plan reserve) had been granted as of December 31, 2020. At the Company’s 2020 Annual Meeting of Shareholders, 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. The Company records compensation expense for the fair value of stock-based awards determined as of the grant date, including employee stock options and restricted stock awards, over the determined requisite service period, which is generally ratably over the vesting term. For the nine months ended September 30, 2023 and 2022, 46,400 and 19,600 stock options were granted under the 2020 Incentive Plan, respectively. The Company recognized $10,000 and $39,000 in stock-based compensation expense for the nine months ended September 30, 2023 and 2022, respectively, related to outstanding options previously granted under the 2004 Option Plan. For the nine months ended September 30, 2023 and 2022, 227,600 and 13,600 restricted stock awards were granted under the 2020 Incentive Plan, respectively. The Company recognized $58,000 and $80,000 in compensation expense associated with outstanding restricted stock awards for the nine months ended September 30, 2023 and 2022, respectively. As of September 30, 2023, $966,000 of total unrecognized compensation cost related to outstanding restricted stock awards was expected to be recognized over a weighted-average remainder period of 2.86 years.

Income Tax Disclosure [Text Block]	14. 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.
