Loans, Notes, Trade and Other Receivables Disclosure [Text Block]	3. TRADE ACCOUNTS RECEIVABLE Trade accounts receivable amounted to $2,554,766 and $3,771,133 as of September 30, 2025 and December 31, 2024, respectively. No allowance for credit losses or product returns was recorded as of September 30, 2025 or December 31, 2024. We consider a broad range of information to estimate credit losses. Historically, we have experienced a very low level of credit loss expense, and most of our trade receivables are collected by the due date or within a few days of the due date. We anticipate no future events or conditions that would impact our ability to collect our accounts receivable. Because of the generally short duration from the balance sheet date to the date of collection, our collection rate is not expected to be significantly impacted by events occurring after the balance sheet date. The trade accounts receivable balances included $22,387 and $52,097 due from a related party as of September 30, 2025 and December 31, 2024, respectively. See Note 17.
