The United States accepts Chinese standard masks, and companies have been approved for export

A document on the U.S. Food and Drug Administration (FDA) website shows that the FDA has provided EUA authorization for some models of masks produced by four Chinese companies, namely BYD Precision, BeiBeiSafety Co., Ltd (headquartered in Taiwan, China), Fujian Kangchen Daily Necessities Co., Ltd., and Weini Technology Development Co., Ltd. The FDA once excluded Chinese standard KN95 masks from the scope of authorization. This newly released document marks that KN95 masks produced in accordance with Chinese standards have been officially recognized by the US regulatory authorities.
