On August 3, 2026, the Forced Labor Enforcement Task Force added 43 companies to the UFLPA Entity List, taking it from 144 entities to 187 — roughly a 30 percent increase in a single action. If a company on that list touched your goods at any tier, U.S. Customs and Border Protection (CBP) presumes those goods were made with forced labor and treats them as barred from entry until you prove otherwise. This is what the expansion actually changed, what a detention costs you while it runs, and what evidence the statute requires before merchandise moves.
What Changed on August 3, 2026
The Uyghur Forced Labor Prevention Act (UFLPA) is the 2021 law that bars goods linked to forced labor in China's Xinjiang Uyghur Autonomous Region (XUAR). It directs an interagency Forced Labor Enforcement Task Force (FLETF), chaired by the Department of Homeland Security, to maintain a public list of entities whose goods fall under the law's import ban. That list was revised by a Federal Register notice published August 3, 2026 (document 2026-15628), effective the same day.
The notice added 43 companies and made technical corrections to two entities already listed. Four of the additions went onto the list of entities working with the XUAR government to recruit or transport transferred labor; 41 went onto the list of facilities and entities sourcing material from Xinjiang or from state labor-transfer programs. Two companies appear on both. Net result: 187 entities on the list as of the notice's effective date.
As of August 27, 2026, no later Federal Register notice revising the list has published, so 187 is the operative count. Treat it as a moving number anyway — the list is revised by notice on no fixed schedule, and August showed how large one revision can be. Build screening that re-runs against a new list, not around a number you hardcoded once.
Where the Additions Landed, and Why That Detail Matters
The UFLPA requires FLETF to maintain five distinct lists: entities in the XUAR that mine, produce, or manufacture goods with forced labor; entities working with the XUAR government to recruit, transport, transfer, harbor, or receive forced labor; the products of those entities; entities that export those products to the United States; and facilities and entities — including the Xinjiang Production and Construction Corps — that source material from the XUAR or from "poverty alleviation" and "pairing-assistance" labor programs.
Forty-one of the 43 August additions went onto that last category. That is the one to read closely, because it is not a geography filter. It captures companies on the basis of what they buy, not where they sit. A supplier in a coastal province — or, in principle, outside China entirely — can be listed for sourcing Xinjiang-origin material. If your risk model is essentially a check on the ship-from address or the manufacturer's provincial code, this is exactly the kind of exposure it does not see.
The sectors named in the notice reinforce the point: cotton and textiles, aluminum, silicon and polysilicon, copper, molybdenum, gold, lithium, potassium, coal, battery materials, pharmaceuticals, food processing, sugar, tomatoes, and hair products. Several of those — polysilicon, battery inputs, pharmaceutical ingredients, refined metals — sit several tiers down a bill of materials, in components an importer of a finished good may never have priced directly.
UFLPA Is a Ban. The Forced-Labor Section 301 Is a Tariff.
These two get conflated constantly, and the confusion is expensive, because the remedies are unrelated.
UFLPA is an admissibility bar. Section 3(a) of the statute creates a rebuttable presumption that covered goods are prohibited under Section 307 of the Tariff Act of 1930 (19 U.S.C. 1307) and are "not entitled to entry at any of the ports of the United States." There is no rate. There is no line on the entry summary you can pay to make it go away. Either the goods come in or they do not.
The forced-labor Section 301 action is a duty. Effective 12:01 a.m. Eastern on July 24, 2026, the U.S. Trade Representative imposed additional ad valorem duties on goods from roughly 60 economies that USTR found fail to impose and effectively enforce a prohibition on forced-labor imports. The rates: 10 percent for a named group including Argentina, Bangladesh, Cambodia, Canada, Ecuador, El Salvador, Guatemala, Honduras, India, Indonesia, Jordan, Malaysia, Mexico, Pakistan, Sri Lanka, Trinidad and Tobago, and the United Kingdom; 10 percent net of the MFN rate for the European Union and Taiwan; 12.5 percent net of MFN for Japan, South Korea, and Switzerland; and 12.5 percent for all other investigated economies, a group that includes China. Goods loaded before the effective date and entered before 12:01 a.m. Eastern on July 28, 2026 were carved out, and Section 232 articles and parts are excepted along with the products listed in the action's annexes.
So the same Chinese-origin shipment can carry a forced-labor Section 301 duty and be detained under UFLPA. Paying the duty does nothing for the detention. Clearing the detention does not refund the duty. Our forced-labor tariffs page covers the exemption structure on the duty side, and our 2026 tariff stacking guide covers how the forced-labor Section 301 layers with everything else on the entry.
What Screening Looks Like When It Actually Works
Most screening programs check a vendor master against the list on a schedule and call it done. That catches direct listings and little else. A program built for the August 2026 list looks different in four ways.
It screens material, not just vendors. Because the largest category of additions is defined by sourcing, the question you need answered is "where did the polysilicon come from," not "is my panel assembler on the list." That means keyed-to-input traceability for your high-risk commodities, gathered before anything is detained.
It screens names the way CBP does. Listed entities have aliases, transliterations, former names, parents, and subsidiaries. Exact-string matching against a Latin-script vendor name is not screening. Match on aliases and addresses, and re-run when a supplier restructures.
It re-screens backward, not just forward. After a revision, open purchase orders and in-transit cargo need to be re-run against the new list, not just future POs. Goods on the water on August 3, 2026 were subject to the revised list on arrival.
It keeps the file current, not retrievable-in-theory. Documentation you have to go ask a tier-three supplier for during a detention is documentation you effectively do not have. Our step-by-step UFLPA compliance guide walks through supply-chain mapping and the documentation package in detail, and our supply-chain due diligence guide covers the supplier-verification side.
What a Detention Costs, and the Clock That Runs
The costs of a UFLPA detention are the ones nobody budgets: demurrage and per diem while containers sit, warehouse storage, the labor hours of assembling an evidence package, and working capital tied up in inventory you cannot sell. Those scale with time, and the timeline is not under your control. CBP publishes running detention, release, and denial figures on its UFLPA enforcement statistics dashboard; read your sector's numbers there rather than trusting a figure quoted in an article, including this one, since the totals move every month.
The procedural clock is set by 19 CFR 151.16. CBP must issue a detention notice within five business days of the decision to detain, or of failing to release merchandise within five business days. That notice has to state the date the detention began, the specific reason, the anticipated length, the nature of the tests or inquiries CBP will conduct, and what information might accelerate resolution. Read that last item carefully — it is the closest thing to a roadmap you get.
CBP must then make a final determination on admissibility within 30 days of the date the merchandise was presented for examination. If CBP does not, the regulation treats the failure as a decision to exclude the merchandise, which is protestable under 19 U.S.C. 1514(a)(4).
If merchandise is excluded, a protest is filed within 180 days of the decision under 19 CFR 174.12(e). Protests against exclusion get a faster track on CBP's side: under 19 CFR 174.21(b), CBP is to act on an exclusion protest within 30 days of filing, and if it does not, the protest is treated as denied for purposes of judicial review. That deemed denial is a feature, not a dead end — it is what lets a stalled case move to court rather than sitting indefinitely.
The Evidence Bar for Release
There are two fundamentally different arguments an importer can make, and mixing them up wastes the 30-day window.
The first is that the UFLPA does not apply to your goods at all — no XUAR nexus, no listed entity anywhere in the chain. This is a traceability argument, and it is won with records: bills of materials tied to specific lots, mill and smelter certificates, production and shipping records that account for the material from origin forward.
The second is the statutory exception, which concedes the connection and argues the goods still qualify for entry. That bar is set in section 3(b) of the UFLPA and it is high. CBP may grant an exception only on determining that the importer (1) has fully complied with the guidance issued under section 2(d)(6) and any implementing regulations, (2) has completely and substantively responded to all CBP inquiries for information, and (3) has demonstrated by clear and convincing evidence that the good was not mined, produced, or manufactured wholly or in part by forced labor.
"Clear and convincing" is a demanding civil standard — meaningfully above the more-likely-than-not threshold most importers assume. In practice it means documentary traceability rather than supplier attestations. A signed letter saying "we do not source from Xinjiang" is not evidence of where the cotton came from; the ginning records are.
One consequence importers rarely anticipate: section 3(c) requires the Commissioner to report each granted exception to Congress and make it public within 30 days, identifying the good and the evidence considered. Exceptions are not confidential.
CBP consolidated its operational guidance for importers into a single forced-labor enforcement document in 2026, covering UFLPA alongside the other forced-labor authorities; it is published on CBP's forced labor guidance page and is the document to work from when you build a package. Nothing in this article predicts how CBP will decide any particular case — the agency evaluates each submission on its own record.
What to Do in the Next Two Weeks
Re-screen your active supplier base against the list as revised August 3, 2026, including tier-two and tier-three suppliers you have visibility into. Then re-screen open purchase orders and anything on the water, since arrival date is what matters.
For your highest-risk commodities — cotton, aluminum, polysilicon, battery materials, and the other sectors named in the notice — pull the traceability file now and find the gaps while nothing is detained. The gap you find in September is a sourcing conversation; the same gap in a detention notice is a 30-day scramble.
Separately, handle the tariff question on its own track. If you have filed entries since July 24, 2026 without checking the forced-labor Section 301 exemption annexes, some of those entries may have been overpaid. A Post Summary Correction (PSC — the mechanism for amending an entry summary before liquidation) is $150 per PSC entry with us for up to 10 lines. That is a duty-recovery question, entirely separate from any admissibility question, and it has its own deadline tied to each entry's liquidation date.
No. The Entity List is one trigger for the rebuttable presumption, not the whole of it. The presumption reaches any goods mined, produced, or manufactured wholly or in part in the XUAR, whether or not a listed company is involved, and CBP can detain on other risk indicators. A clean list screen is necessary, not sufficient.
What's the practical difference between a UFLPA detention and the forced-labor Section 301 tariff?
UFLPA blocks entry; the Section 301 action adds duty. Under UFLPA, goods are presumed prohibited under 19 U.S.C. 1307 and are not entitled to entry until the presumption is overcome. The forced-labor Section 301 action, effective July 24, 2026, adds 10 or 12.5 percent ad valorem depending on the economy of origin, and those goods clear normally once the duty is paid. Different problems, different remedies.
How long do I have to respond once my shipment is detained?
The controlling deadline is CBP's, not yours: under 19 CFR 151.16, CBP must make a final admissibility determination within 30 days of the date the merchandise was presented for examination, and a failure to do so is treated as an exclusion. Practically, that means your evidence package needs to be in CBP's hands well inside 30 days, which is why the file has to exist before the detention.
If I pay the forced-labor Section 301 duty, does that release a UFLPA hold?
No. The two operate under entirely different authorities. The Section 301 duty is a cost imposed on admissible goods; the UFLPA presumption is a bar on admissibility. Duty payment has no bearing on a detention, and release from a detention does not refund duty.
Where Strix Fits
Four ways we work with importers on this, depending on what you actually need. We clear — licensed customs brokers file your entries at all U.S. ports and manage the entry-side response when a shipment is held. We consult — our compliance team reviews your screening process and traceability documentation against the list as it stands today, before a detention forces the question. We comply — entity screening, classification, origin documentation, and PSC filings handled as ongoing work rather than emergencies. And we automate — ABI-certified self-filing software at $30 per entry, so your screening and filing live in one workflow instead of two spreadsheets.
The August 3, 2026 expansion moved 43 more companies inside the presumption, and most of them were listed for what they source rather than where they sit. If you are not sure whether that reaches your supply chain, that uncertainty is the finding. Talk to our team or start with our compliance consulting services — a screening review costs a great deal less than a container sitting at a terminal while you look for mill certificates.
