Significant Accounting Policies [Text Block]	1 Business description Superior Group of Companies, Inc. (together with its subsidiaries, “the Company,” “Superior,” “we,” “our,” or “us”) was organized in 1920 1922 1998, May 3, 2018, Superior’s Uniforms and Related Products segment, through its primary signature marketing brands Fashion Seal Healthcare ® ® ® third Superior services its Remote Staffing Solutions segment through multiple The Office Gurus ® The Promotional Products segment, through the BAMKO ® ® ® Basis of presentation The accompanying consolidated financial statements of Superior included herein have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) (“U.S.” or “United States”) and the rules and regulations of the Securities and Exchange Commission (the “SEC”). The Company refers to the consolidated financial statements collectively as “financial statements,” and individually as “statements of comprehensive income,” “balance sheets,” “statements of shareholders’ equity,” and “statements of cash flows” herein. Use of estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of assets, liabilities, revenue and expenses, as well as the disclosures of contingent assets and liabilities. Because of the inherent uncertainties in this process, actual future results could differ from those expected at the reporting date. Cash and cash equivalents The Company considers all highly liquid investments with an original maturity of three Revenue recognition Revenue is recognized when control of the promised goods or services are transferred to our customers, in an amount that reflects the consideration that we expect to receive in exchange for those goods or services. See Note 14 Accounts receivable and allowance for doubtful accounts Judgments and estimates are used in determining the collectability of accounts receivable and in establishing allowances for doubtful accounts. The Company analyzes specific accounts receivable and historical bad debt experience, customer credit worthiness, current economic trends and the age of outstanding balances when evaluating the adequacy of the allowance for doubtful accounts. Changes in estimates are reflected in the period they become known. Charge-offs of accounts receivable are made once all collection efforts have been exhausted. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may Accounts receivable-other The Company purchases raw materials and has them delivered to certain suppliers of the Company. The Company pays for the raw materials and then deducts the cost of these materials from payments to the suppliers at the time the related finished goods are invoiced to the Company by those suppliers. Cost of goods sold and shipping and handling fees and costs Cost of goods sold for our Uniforms and Related Products segment and our Promotional Products segment consist primarily of direct costs of acquiring inventory, including cost of merchandise, inbound freight charges, purchasing, receiving and inspection costs. Cost of goods sold for our Remote Staffing Solutions segment includes salaries and payroll related benefits for agents. The Company includes shipping and handling fees billed to customers in net sales. Shipping and handling costs associated with out-bound freight are generally recorded in cost of goods sold. Other shipping and handling costs are included in selling and administrative expenses and totaled $17.6 million, $14.5 million and $14.0 million for the years ended December 31, 2020 2019 2018 Inventories Inventories are stated at the lower of cost ( first first may Property, plant and equipment Property, plant and equipment are stated at cost, less accumulated depreciation and amortization.

Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Goodwill and indefinite-lived intangible assets such as trade names are not fourth may not • macroeconomic conditions such as deterioration in general economic conditions, limitations on accessing capital, or other developments in equity and credit markets; • industry and market considerations such as a deterioration in the environment in which the Company operates, an increased competitive environment, a decline in market-dependent multiples or metrics (considered in both absolute terms and relative to peers), a change in the market for the Company’s products or services, or a regulatory or political development; • cost factors such as increases in raw materials, labor, or other costs that have a negative effect on earnings and cash flows; • overall financial performance such as negative or declining cash flows or a decline in actual or planned revenue or earnings compared with actual and projected results of relevant prior periods; • other relevant entity-specific events such as changes in management, key personnel, strategy, or customers. Goodwill and indefinite-lived intangible assets are tested at a level of reporting referred to as “the reporting unit.” The Company’s reporting units are defined as each of its three reporting segments. As of December 31, 2020 December 31, 2020 An entity has the option to first not 50% not not December 31, 2020 2019 2018 Contingent Consideration The Company recognizes the fair value of estimated contingent consideration at the acquisition date as part of the consideration transferred in exchange for the acquired business. The contingent consideration is remeasured to fair value at each reporting date until the contingency is resolved. Any changes in fair value are recognized each reporting period in non-cash changes in fair value of estimated contingent consideration in the accompanying statements of comprehensive income. Employee benefits Pension plan costs are funded currently based on actuarial estimates, with prior service costs amortized over 20 years. The Company recognizes settlement gains and losses in its financial statements when the cost of all lump sum settlements in a year is greater than the sum of the service cost and interest cost components of net periodic pension cost for the plan for the year. Insurance The Company self-insures for certain obligations related to employee health programs. The Company also purchases stop-loss insurance policies to protect it from catastrophic losses. Judgments and estimates are used in determining the potential value associated with reported claims and for losses that have occurred, but have not may Taxes on income Income taxes are provided for under the liability method, whereby deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carryforwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not not Note 7 Share-based compensation The Company awards share-based compensation as an incentive for employees to contribute to the Company’s long-term success. The Company grants options, stock-settled stock appreciation rights, restricted stock, and performance shares. The Company recognizes share-based compensation expense for all awards granted to employees, which is based on the fair value of the award on the date of grant. Determining the appropriate fair value model and calculating the fair value of stock compensation awards requires the input of certain highly complex and subjective assumptions, including the expected life of the stock compensation awards and the Company’s common stock price volatility, risk free interest rate and dividend rate. The assumptions used in calculating the fair value of stock compensation awards represent management’s best estimates, but these estimates involve inherent uncertainties and the application of judgment. As a result, if factors change and the Company deems it necessary to use different assumptions, stock compensation expense could be materially different from what has been recorded in the current period. Other comprehensive income Other comprehensive income (loss) is defined as the change in equity during a period, from transactions and other events, excluding changes resulting from investments by owners (e.g., supplemental stock offering) and distributions to owners (e.g., dividends). Risks and concentrations Financial instruments that potentially subject the Company to concentrations of credit risk include cash in banks in excess of federally insured amounts. The Company manages this risk by maintaining all deposits in high quality financial institutions and periodically performing evaluations of the relative credit standing of the financial institutions. When assessing credit risk the Company considers whether the credit risk exists at both the individual and group level. Consideration is given to the activity, region and economic characteristics when assessing if there exists a group concentration risk.

The majority of such fabrics are sourced in China. The Promotional Products segment relies on the supply of different types of raw materials as well as textiles, including plastic, glass, fabric and metal. The vast majority of these raw materials are principally sourced from China, either directly by BAMKO or its suppliers. If we are unable to continue to obtain our raw materials and finished products from China or if our suppliers are unable to source raw materials from China, it could significantly disrupt our business.

Stock options are also granted to outside members of the Board of Directors of the Company. The Company determines the fair value of stock options and SARs at the date of grant using the Black-Scholes valuation model.

The risk-free interest rate is based on the yield of a U.S. treasury bond with a similar maturity to the award’s expected life. The expected life for awards granted is based on the historical exercise patterns experienced by the Company when the award is made. The determination of expected stock price volatility for awards is based on historical Superior common stock prices over a period commensurate with the expected life. The dividend yield assumption is based on the history and expectation of the Company’s dividend payouts.

Accounting Policies [Abstract]
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and indefinite-lived intangible assets The Company has made acquisitions in the past that included goodwill and indefinite-lived intangible assets. Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Goodwill and indefinite-lived intangible assets such as trade names are not fourth may not • macroeconomic conditions such as deterioration in general economic conditions, limitations on accessing capital, or other developments in equity and credit markets; • industry and market considerations such as a deterioration in the environment in which the Company operates, an increased competitive environment, a decline in market-dependent multiples or metrics (considered in both absolute terms and relative to peers), a change in the market for the Company’s products or services, or a regulatory or political development; • cost factors such as increases in raw materials, labor, or other costs that have a negative effect on earnings and cash flows; • overall financial performance such as negative or declining cash flows or a decline in actual or planned revenue or earnings compared with actual and projected results of relevant prior periods; • other relevant entity-specific events such as changes in management, key personnel, strategy, or customers. Goodwill and indefinite-lived intangible assets are tested at a level of reporting referred to as “the reporting unit.” The Company’s reporting units are defined as each of its three reporting segments. As of December 31, 2020 December 31, 2020 An entity has the option to first not 50% not not December 31, 2020 2019 2018
Business Combinations Policy [Policy Text Block]	Contingent Consideration The Company recognizes the fair value of estimated contingent consideration at the acquisition date as part of the consideration transferred in exchange for the acquired business. The contingent consideration is remeasured to fair value at each reporting date until the contingency is resolved. Any changes in fair value are recognized each reporting period in non-cash changes in fair value of estimated contingent consideration in the accompanying statements of comprehensive income.
Pension and Other Postretirement Plans, Policy [Policy Text Block]	Employee benefits Pension plan costs are funded currently based on actuarial estimates, with prior service costs amortized over 20 years. The Company recognizes settlement gains and losses in its financial statements when the cost of all lump sum settlements in a year is greater than the sum of the service cost and interest cost components of net periodic pension cost for the plan for the year.
Insurance [Policy Text Block]	Insurance The Company self-insures for certain obligations related to employee health programs. The Company also purchases stop-loss insurance policies to protect it from catastrophic losses. Judgments and estimates are used in determining the potential value associated with reported claims and for losses that have occurred, but have not may
Income Tax, Policy [Policy Text Block]	Taxes on income Income taxes are provided for under the liability method, whereby deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carryforwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not not Note 7
Share-based Payment Arrangement [Policy Text Block]	Share-based compensation The Company awards share-based compensation as an incentive for employees to contribute to the Company’s long-term success. The Company grants options, stock-settled stock appreciation rights, restricted stock, and performance shares. The Company recognizes share-based compensation expense for all awards granted to employees, which is based on the fair value of the award on the date of grant. Determining the appropriate fair value model and calculating the fair value of stock compensation awards requires the input of certain highly complex and subjective assumptions, including the expected life of the stock compensation awards and the Company’s common stock price volatility, risk free interest rate and dividend rate. The assumptions used in calculating the fair value of stock compensation awards represent management’s best estimates, but these estimates involve inherent uncertainties and the application of judgment. As a result, if factors change and the Company deems it necessary to use different assumptions, stock compensation expense could be materially different from what has been recorded in the current period.
Comprehensive Income, Policy [Policy Text Block]	Other comprehensive income Other comprehensive income (loss) is defined as the change in equity during a period, from transactions and other events, excluding changes resulting from investments by owners (e.g., supplemental stock offering) and distributions to owners (e.g., dividends).
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Risks and concentrations Financial instruments that potentially subject the Company to concentrations of credit risk include cash in banks in excess of federally insured amounts. The Company manages this risk by maintaining all deposits in high quality financial institutions and periodically performing evaluations of the relative credit standing of the financial institutions. When assessing credit risk the Company considers whether the credit risk exists at both the individual and group level. Consideration is given to the activity, region and economic characteristics when assessing if there exists a group concentration risk.

The majority of such fabrics are sourced in China. The Promotional Products segment relies on the supply of different types of raw materials as well as textiles, including plastic, glass, fabric and metal. The vast majority of these raw materials are principally sourced from China, either directly by BAMKO or its suppliers. If we are unable to continue to obtain our raw materials and finished products from China or if our suppliers are unable to source raw materials from China, it could significantly disrupt our business.
