CY2023	us-gaap	Concentration Risk Credit Risk ConcentrationRiskCreditRisk	<p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of cash, trade accounts receivable and advances to suppliers. All of the Company’s cash is maintained with banks within the People’s Republic of China of which no deposits are covered by insurance. The Company has not experienced any losses in such accounts. A significant portion of the Company’s sales are credit sales which are primarily to customers whose ability to pay is dependent upon the industry economics prevailing in these areas. The Company also makes cash advances to certain suppliers to ensure the stable supply of key raw materials. The Company performs ongoing credit evaluations of its customers and key suppliers to help further reduce credit risk.</p>
