What UFLPA screening actually requires

The Uyghur Forced Labor Prevention Act (UFLPA), signed into law December 23, 2021 and in effect since June 21, 2022, changed the default posture at the U.S. border for a specific category of goods. It’s worth being precise about what it actually does, because the mechanism is different from most import-compliance rules.

The rebuttable presumption

UFLPA creates a rebuttable presumption: goods mined, produced, or manufactured wholly or in part in China’s Xinjiang region — or produced by an entity on the UFLPA Entity List maintained by the DHS-led Forced Labor Enforcement Task Force (FLETF) — are presumed to have been made with forced labor and are barred from entry into the United States. The burden sits with the importer to rebut that presumption with clear and convincing evidence. In practice this inverts the usual order of operations: U.S. Customs and Border Protection can detain a shipment first and require the importer to prove it’s clean second, rather than the importer needing to prove a problem exists before anything is held.

What a real pre-shipment check has to cover

Because the presumption attaches to both a specific list of named entities and a broader regional-origin question, a meaningful screen has to check more than a single list:

• The UFLPA Entity List itself, published by DHS/FLETF — a real, public, keyless list (currently served as an HTML table at dhs.gov) naming specific companies whose goods are subject to the presumption.
• The Consolidated Screening List (CSL) — the U.S. government’s combined denied- and restricted-party list, since forced-labor exposure and export-control/denied-party risk frequently show up on the same supplier.
• Antidumping/countervailing duty (AD/CVD) exposure for the shipment’s specific HTS classification and country of origin — a separate enforcement track from UFLPA, but one that’s commonly checked (or missed) in the same pre-shipment review, and one that can apply retroactively.

Here’s a detail that matters if you’re building or buying a screening tool rather than just reading about the law: not all three of these sources are equally accessible. The UFLPA Entity List itself needs no account or key — it’s a public HTML table anyone can fetch. The Consolidated Screening List and AD/CVD case data, by contrast, sit behind trade.gov’s Developer Portal and require a registered API key; unauthenticated requests to either are rejected outright. And AD/CVD’s own public web search tool has no simpler path around that — it’s a stateful, session-bound web application, not a page with a plain underlying data endpoint, so there’s no shortcut that avoids registering for the key. A tool that claims to check all three “for free” without that key is either not actually checking two of them, or is doing something more fragile than a documented API call.

What “no match” should — and shouldn’t — tell you

A “no match” result only means the specific sources actually queried didn’t return a match at the time of the check. It is not, by itself, a guarantee that a shipment or supplier is free of forced-labor or trade-enforcement exposure — especially if one of the three sources above wasn’t actually reached live. A screening result is only as useful as its own honesty about which sources it actually hit.

How Aervik Labs’ US Import Risk Screening API handles this

The US Import Risk Screening API takes an HTS number, country of origin, and optionally a supplier or manufacturer name, and checks it against the UFLPA Entity List, the Consolidated Screening List, and AD/CVD case exposure for that HTS/country combination in one call — returning a deterministic overall exposure rating (none / low / elevated / high) calculated the same way every time from the same inputs, never an AI judgment call. Every response discloses, per source, whether that section reflects a real, currently-wired government data call or a placeholder awaiting a data-source credential, so incomplete_coverage is something you can see and act on, not something hidden behind a clean-looking result.
