Loans, Notes, Trade and Other Receivables Disclosure [Text Block] | 6. TRADE RECEIVABLES Trade receivables are presented net of the related allowance for uncollectible accounts of approximately $332,000, $242,000 and $192,000 at September 30, 2021, December 31, 2020 and September 30, 2020, respectively. We record the allowance based on historical experience, the age of the receivables, and identification of customer accounts that are likely to prove difficult to collect due to various criteria including pending bankruptcy. However, estimates of the allowance in any future period are inherently uncertain and actual allowances may differ from these estimates. If actual or expected future allowances were significantly greater or less than established reserves, a reduction or increase to bad debt expense would be recorded in the period this determination was made. Our credit policy generally provides that trade receivables will be deemed uncollectible and written-off once we have pursued all reasonable efforts to collect on the account. In accordance with ASC 606, the return reserve liability netted against trade receivables was approximately $1,583,000, $1,348,000 and $1,198,000 at September 30, 2021, December 31, 2020 and September 30, 2020, respectively.
