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).
Devices with RF functions need an FCC ID (Certification) or SDoC before import / marketing (for foreign manufacturers the U.S. importer is the responsible party). Covered List equipment cannot be authorized. Form 740 was eliminated on 2017-11-02.

The importer is the "manufacturer": test under the DOE test procedure and certify each basic model in CCMS before distribution in commerce (annual update). Non-compliant products "shall be refused admission" (§429.5); no ACE data element.
2025–26: The 2024-10 certification rule was disapproved under the CRA (Pub. L. 119-8, 2025-05-09) and the CFR reverted on 2025-09-09; the 2015 ACE import-declaration NOPR was never finalized
