If you buy batteries, steel, or aluminum, your forced-labor exposure changed in 2026. U.S. Customs and Border Protection stopped roughly 7,325 shipments for Uyghur Forced Labor Prevention Act (UFLPA) review in FY2025 — more than 50% above the prior year — and the enforcement task force has folded lithium into its list of high-priority sectors. For procurement teams in automotive, electronics, and consumer goods, the rebuttable presumption is no longer a paperwork risk. It is a supply risk.
Summary: UFLPA enforcement intensified in 2026, with CBP detaining a record volume of shipments and adding lithium to its high-priority sectors alongside steel, copper, aluminum, and PVC. Goods with any input from China’s Xinjiang region face a rebuttable presumption of forced labor and are blocked unless the importer proves a clean chain of custody. This post maps the 2026 enforcement picture and gives procurement teams a practical readiness playbook — built on multi-tier supplier visibility and verified evidence.
UFLPA enforcement by the numbers
- CBP stopped about 7,325 shipments for UFLPA review in FY2025 — over 50% more than FY2024 (CBP UFLPA dashboard).
- Only around 6.5% of reviewed shipments were ultimately released into U.S. commerce (CBP).
- More than 18,000 shipments worth roughly $3.81 billion have been reviewed since the Act took effect (CBP, early 2026).
- High-priority sectors now include lithium, steel, copper, aluminum, and PVC (Forced Labor Enforcement Task Force, Aug 2025 strategy update).
What changed in UFLPA enforcement for 2026
The shift is one of both scale and scope. CBP is detaining far more shipments, and the task force has widened the materials it targets. Lithium is the headline addition, pulling EV batteries and energy storage squarely into scope.
The practical effect is simple. More categories now carry a higher inspection probability, and the burden sits with the importer to prove a shipment is clean. If you cannot show where a material came from, it does not move.
The new high-priority materials — and who’s exposed
Lithium’s addition matters because it sits deep in products few teams trace fully: EV batteries, grid storage, and consumer electronics. Steel and aluminum reach into automotive, construction, and packaging. If your bill of materials touches any of these, your exposure rose in 2026.
The risk rarely sits with your Tier 1 supplier. It hides two or three tiers down, in a smelter or a refiner you have never assessed. That is why multi-tier visibility is now the core of UFLPA readiness, not an optional extra. Our supplier risk management guide covers the framework.
The detention math: why the rebuttable presumption is so costly
Under UFLPA, goods linked to the Xinjiang region are presumed to involve forced labor and are blocked at the border. The presumption is rebuttable, but the burden is entirely on the importer to prove otherwise with clear, convincing evidence.
The numbers show how steep that is: only about 6.5% of reviewed shipments make it into U.S. commerce. A detention is not a delay you can plan around — it is a stalled shipment, a stranded cost, and a customer you may not be able to supply.

Building a chain of custody that survives a CBP review
A defensible response starts before the detention notice. You need traceability from the raw material to the finished good, supplier attestations you can verify, and documentary evidence — not just certificates on file. CBP wants to see the flow of goods, not a promise.
That means mapping sub-tier suppliers, collecting evidence at each link, and keeping it audit-ready. A supplier audit platform that captures responses through frictionless links — no portals or logins for the supplier — is how teams reach suppliers who would otherwise ignore the request.
From certificates to verified supplier evidence
Collecting a certificate is not the same as verifying it. The teams that clear detentions fastest treat every supplier claim as a finding that needs evidence and follow-up — the same closed-loop discipline behind verified closure in quality and safety.
Practically: assign an owner to each high-risk material, require traceability evidence, and re-trigger the assessment when a supplier or source changes. The goal is a living record you can hand to CBP, not a folder you scramble to assemble after a shipment stops. Our guide to building a multi-tier supplier audit program walks through the operational steps.
Key Takeaways:
- UFLPA shipment reviews rose more than 50% in FY2025, with only ~6.5% of reviewed goods released.
- Lithium joined steel, copper, aluminum, and PVC as a 2026 high-priority material.
- The rebuttable presumption puts the burden of proof on the importer, with clear evidence required.
- Risk hides in Tier 2 and Tier 3 — multi-tier visibility is now core to UFLPA readiness.
- Verify supplier evidence, don’t just collect certificates, and keep the record audit-ready.

Frequently Asked Questions (FAQs)
What is the UFLPA?
The Uyghur Forced Labor Prevention Act is a U.S. law that presumes any goods made wholly or partly in China’s Xinjiang region involve forced labor. Such goods are blocked from import unless the importer proves otherwise with clear and convincing evidence.
Which materials are high-priority for UFLPA in 2026?
The Forced Labor Enforcement Task Force’s 2025 strategy update lists lithium, steel, copper, aluminum, and PVC as high-priority sectors, alongside long-standing focus areas such as cotton, polysilicon, and tomatoes.
What is the rebuttable presumption?
It means CBP assumes goods with a Xinjiang nexus are made with forced labor and detains them by default. The importer must rebut that assumption with traceability and evidence before the goods can be released.
How do I prove my supply chain is clean?
You map your suppliers to the sub-tier level, collect traceability evidence from raw material to finished good, and verify supplier attestations rather than filing them. A living, audit-ready record is what satisfies a CBP review.
How is UFLPA different from the EU’s CSDDD?
UFLPA is a U.S. import-enforcement law focused on forced labor with a rebuttable presumption at the border. CSDDD is an EU due-diligence directive requiring companies to identify and mitigate human-rights and environmental harms across their value chain. Many global firms must comply with both.
