CBP Detained Your Shipment Under the UFLPA: The 30-Day Response Plan

A UFLPA detention starts a clock: generally 30 days to respond, with up to two 30-day extensions — while you pay storage and demurrage the entire time. Under CBP's June 2026 operational guidance, here is what happens in the first days after a detention notice, what a winning admissibility package contains, and the three decisions that determine whether the cargo moves again.

A UFLPA detention is not an ordinary CBP hold. The government does not have to prove anything: goods produced wholly or in part in China's Xinjiang region (XUAR), or by an entity on the UFLPA Entity List, are presumed made with forced labor and barred from entry unless the importer rebuts the presumption by clear and convincing evidence. The burden is yours, the clock is short, and the storage bill is yours too. Under CBP's June 9, 2026 operational guidance for importers (Publication 5560-0526), here is how the response actually works.

This article reflects CBP's operational guidance for importers published June 9, 2026 (Publication No. 5560-0526), which supersedes the June 13, 2022 UFLPA guidance. Enforcement priorities, timelines, and the UFLPA Entity List change over time — confirm current requirements against CBP's official forced-labor resources and your detention notice, and consult legal counsel on specific shipments.

The Clock: What Happens After the Detention Notice

For a UFLPA detention involving a potential input, the importer generally has 30 days to respond, with up to two 30-day extensions — roughly 90 days at the outside. Throughout that window, the importer pays all storage and demurrage, and CBP may require a single-transaction bond of three times the value of the detained merchandise. For goods that are a direct input from the XUAR or an Entity List entity, and for CAATSA cases, the shipment is excluded rather than detained; the review path there is a protest filed within 180 days under 19 U.S.C. § 1514.

The Decision: Export, Destroy, or Fight

Three paths exist, and the honest first step is a cold cost analysis. Exporting stops the carrying costs but forfeits the sale and does nothing for future shipments of the same product. Destruction is rare but sometimes cheaper than months of storage on low-value cargo. Demonstrating admissibility is the only path that gets the goods released — and the only one that establishes a record for the next shipment. It comes in two forms: an applicability review (showing the goods are outside the UFLPA's scope entirely) or an exception review (rebutting the presumption with clear and convincing evidence). Scope arguments, where available, are generally the faster fight.

Importing in a high-priority sector and not sure your documentation would survive a detention?

The Submission: What the Forced Labor Portal Package Must Prove

Admissibility submissions go through CBP's Forced Labor Portal (flportal.cbp.gov), and the standard is unforgiving: the evidence must trace the supply chain to the raw-material stage and answer who, where, how, and what for every input. A single supplier you cannot document can render the entire submission insufficient — and the shipment excluded. The core package includes:

• A certificate of origin signed by the foreign seller, covering the last manufacturing process.
• A detailed importer statement describing the full supply chain.
• Tracing evidence for every tier: manufacturer affidavits, purchase orders, invoices, proof of payment, production records, process flow charts, factory information, and transportation records from raw material to finished goods.

This is why detention response is won or lost before the goods ship. Assembling multi-tier documentation from overseas suppliers inside a 30-day window — across time zones, languages, and suppliers with no incentive to cooperate quickly — is where most submissions fail. Importers in the 12 high-priority sectors (including cotton, polysilicon/silica, aluminum, steel, seafood, and apparel) should maintain the tracing file as a standing part of the product record, not a document hunt that starts with the detention notice.

After Release Is Not Always the End

Release does not extinguish the issue. If goods conditionally released are later found inadmissible, CBP issues a redelivery demand (CBP Form 4647); failure to redeliver can result in liquidated damages up to three times the entered value. And a detention on one shipment is a signal about the supply chain behind it — the same suppliers will be behind the next entry. CTPAT Trade Compliance members get meaningful advantages here: front-of-line admissibility review, preliminary hold notification, and 48-hour advance notice of new enforcement actions affecting their goods.

The Detention Response Checklist

• Read the detention notice carefully — confirm whether it is a UFLPA detention, an exclusion, or a WRO action, because the timeline and review path differ.
• Calendar the response deadline immediately and request extensions early if you intend to fight.
• Run the export-destroy-rebut cost analysis in week one, including storage, demurrage, and bond exposure.
• Determine whether a scope (applicability) argument exists before committing to a full rebuttal.
• Start supplier outreach for tracing documents on day one — multi-tier evidence is the long pole.
• Coordinate roles in writing: who assembles evidence, who files in the Forced Labor Portal, and where counsel signs off.
• After resolution, fix the record: update the supply-chain file so the next shipment of the same product ships with its defense attached.
