Concentration Risk Disclosure [Text Block] | NOTE 12 -- CONCENTRATIONS Milestone Scientific has informal arrangements with third -party manufacturers of the STA, epidural, and intra-articular devices, pursuant to which they manufacture these products under specific purchase orders but without any long-term contract or minimum purchase commitment. Consequently, advances on contracts have been classified as current at March 31, 2021, and December 31, 2020 . The termination of the manufacturing relationship with any of these manufacturers could have a material adverse effect on Milestone Scientific's ability to produce and sell its products. Although alternate sources of supply exist, and new manufacturing relationships could be established, Milestone Scientific would need to recover its existing tools or have new tools produced. Establishment of new manufacturing relationships could involve significant expense and delay. Any curtailment or interruption of the supply, because of termination of such a relationship, would have a material adverse effect on Milestone Scientific's financial condition, business, and results of operations. For the three months ended March 31, 2021, and 2020 an aggregate of approximately 29% and 39% of the Company's net product sales were from one domestic distributor, respectively. Additionally, three months ended March 31, 2021 approximately 18% of the Company's net product sales are to Milestone China. Accounts receivable for the domestic distributor and Milestone China amounted to approximately 28% and 21% of Milestone Scientific's gross accounts receivable as of March 31, 2021, respectively. Accounts receivable for the major customer/distributor amounted to approximately 69% of Milestone Scientific's gross accounts receivable as of December 31, 2020.
