Other import requirements

Supply chain / forced labor (UFLPA · WRO · CAATSA)

Chinese origin: the UFLPA presumption is triggered through the supply chain (Xinjiang inputs / Entity List), not by country of origin; the origins with the most CBP denials are MY / VN / TH.

Not in a UFLPA priority sector, and no WRO or Finding applies to this origin. The UFLPA presumption still applies through the supply chain (Xinjiang content or listed entities).
