The UFLPA for battery and mineral importers

The Uyghur Forced Labor Prevention Act decides whether goods may enter the United States at all, not what duty they pay. Goods made wholly or partly in Xinjiang, or by a company on the UFLPA Entity List, are presumed to be made with forced labor and are refused entry unless the importer proves otherwise. Lithium, aluminum, copper and polysilicon are among its priority sectors, which puts battery and mineral supply chains squarely in scope.

How the presumption works

Since June 21, 2022, US Customs and Border Protection has applied a rebuttable presumption that goods "mined, produced, or manufactured" wholly or in part in Xinjiang, or by entities on the UFLPA Entity List, are made with forced labor and so are barred under 19 U.S.C. 1307 (CBP). To have goods released, the importer must answer CBP's questions fully and show, by clear and convincing evidence, that the goods were not made with forced labor (DHS FAQ).

The test reaches inputs, not just the finished product. A battery assembled outside China can be detained if a material in it traces back to Xinjiang or to a listed company.

The Entity List

DHS publishes the list on its UFLPA Entity List page and in the appendices of Federal Register notices. On July 31, 2026 DHS announced 43 additions, which it called its largest single expansion, bringing the list to 187 entities (DHS release). The presumption applies to the new names from August 3, 2026. On October 14, 2026 the list page still showed its July 31 update as the latest.

Some entities appear on more than one of the list's sub-lists, so counting rows gives a higher number than 187. Search the list for your suppliers and for their suppliers by name, and check again after every update; we do not reproduce it here because it changes.

Priority sectors

DHS names twelve high-priority sectors for enforcement: aluminum, apparel, caustic soda, copper, cotton and cotton products, lithium, PVC, red dates (jujubes), seafood, silica-based products (including polysilicon), steel, and tomatoes and downstream products. Caustic soda, copper, jujubes, lithium and steel were added on August 19, 2025.

For a battery importer, lithium is the direct exposure: lithium chemicals sit near the start of the cathode supply chain. Aluminum and copper go into cell casings, current collectors and busbars, and both are priority sectors too.

It stacks with the other tests

What to have ready before a detention

  1. A map of the supply chain for each product, down to the raw materials in the priority sectors, with each supplier's name and location.
  2. Documents that tie a shipment to that map: purchase orders, invoices, production and transport records for each tier, so a specific entry can be traced, not just the product in general.
  3. Screening records showing each supplier was checked against the Entity List, and when.
  4. Supplier commitments to provide this evidence on request, written into the purchase contract, since the importer carries the burden of proof and will need the supplier's records to meet it.

CBP publishes operational guidance for importers on its UFLPA pages, including the kinds of evidence it reviews. Read it before a shipment is held, not after.
