The US buyer wants a UFLPA statement and the forwarder says a Hong Kong invoice will clear it: the importer files the file, a new letterhead does not lift a hold

Bottom line:

The Uyghur Forced Labor Prevention Act first presumes that goods produced wholly or in part in Xinjiang, or by a producer on the UFLPA Entity List, are barred under 19 U.S.C. § 1307.
Release is the Importer of Record’s supply-chain filing. A Hong Kong invoice, a secretary-office address, or a one-page “no forced labor” letter does not rebut that presumption.
What the factory sends is source paper: contracts, payments, transport, and each supplier’s role. The detention notice and the portal request sit with the importer. The current list is on the DHS Entity List.

The inquiry is often half a sentence: “Need UFLPA statement, ship from your HK company.” If sales replies “fine — we ship from Hong Kong,” the buyer hears: the chain is clean and the box will not be held. The forwarder then adds “just change the letterhead,” and the container looks closed.

Who stands as importer is in US IOR. How much additional duty is due is in 301 follows origin. If the box is already held, first split documents from exam — see cargo held at destination. UFLPA asks whether the goods may enter. It does not read the Hong Kong name on the invoice.

1. The detention notice names the importer

Customs holds the goods on that entry. The notice goes to the Importer of Record. Storage, extensions and portal filings sit on that name. A Hong Kong seller can support the file. It cannot take that field.

CBP’s UFLPA FAQ says a third party may give supply-chain documents to CBP, but the importer should be told. The importer still pays storage. Applicability or exception reviews still go through the Forced Labor Portal as the importer.

So when the forwarder says “I’ll write the letter, you change the name,” the third item does not move. Without the importer’s legal name and tax ID, do not quote “UFLPA clearance included.”

2. The law first assumes the goods cannot enter. The importer has to show otherwise

UFLPA creates a rebuttable presumption: goods mined, produced or manufactured wholly or in part in the Xinjiang Uyghur Autonomous Region, or by an Entity List producer, are treated as forced-labor goods and may not enter. The importer has two routes — not a factory promise letter:

Applicability review: show this shipment and its inputs are not from the XUAR and not from a listed entity.
Exception review: accept that the presumption may apply, then meet the statute — clear and convincing evidence that forced labor was not used, and answers to every CBP inquiry.

A detention notice usually gives time to file. Thirty days is common. The importer may ask the port or the Center for more time before that clock ends. CBP cannot decide on an incomplete pack. It has said a complete, English, supplier-sorted file is what lets review start; a complete pack has often taken about two to three weeks. That is not a guaranteed calendar.

3. The factory sends source documents, not an empty letter

Customs wants papers that already exist in the ordinary course of business, not a poster written after the hold. The FAQ names these. The list is not exhaustive:

Transactions and the chain: packing list, bill of lading, manifest — enough to show origin and where components came from.
The parties: each manufacturing, processing and export role, preferably on a flow chart that contracts and papers can support.
Payment and movement of materials: invoices, contracts, purchase orders, plus proof the money moved and the goods changed hands.

If a supplier fears disclosure, sensitive pages can go straight to CBP while the importer is told they were sent. Commingled inputs stay detained while CBP reads the file. If the same chain was cleared before, the importer should say so and attach a tracing summary so review can move faster.

A Hong Kong letterhead and a mainland plant must tell one story across contract, export entry and bill of lading — see four flows. Rewriting origin after the fact to “help UFLPA” only adds a second story — see origin does not become Hong Kong.

4. Open the current Entity List and sector pages before you ship

DHS publishes the Entity List for the Forced Labor Enforcement Task Force at dhs.gov/uflpa-entity-list. Names are added, removed and corrected. Do not memorise a WeChat table. Aluminum, apparel, copper, cotton, and tomatoes and downstream goods have appeared in addition notices. That is not a closed list of what can be held.

The statute itself names cotton, tomatoes, polysilicon, PVC, aluminum and seafood as priorities. The Task Force later added sectors such as caustic soda, copper, jujubes, lithium and steel. CBP targets across the tariff. Sitting outside a priority sector does not mean the shipment will not be asked about.

The operating manual is the Forced Labor Enforcement Operational Guidance for Importers issued in June 2026. The appendices split tracing examples by sector. The factory maps to the annex. The importer maps to the portal.

5. When the buyer asks for a statement

What the buyer asks	A reply that holds	Do not reply
Send a UFLPA letter. Ship under the Hong Kong company.	The seller is a Hong Kong company. Origin and suppliers follow the actual plant. We can support contracts, payment and transport papers. The importer files the entry and any detention request with CBP.	A Hong Kong letterhead means the US has already released the goods.
You be the importer. You own the file.	We are the seller. The US importer needs to be you or a US company you name. We can prepare documents to a list. We will not file in the portal in your place.	Fine — we will clear under our Hong Kong company and guarantee no hold.
Put “no Xinjiang content” on the showcase for search.	The showcase may say supply-chain papers can be provided. We do not write “compliant” without documents that match the shipment.	Write it now; we will fill it in after signing.
The forwarder said change the name and the origin and it will pass.	The papers have to match the plant. We do not rewrite documents or keep two origin stories.	Make a photocopy the way the forwarder said.

A sample parcel can be held the same way. Low value does not create an exemption — see US samples and de minimis.

6. If the container is already held

Same day, get the detention notice: the basis, the papers asked for, the contact and the deadline.
Confirm who is IOR on the entry. If that is not you, give papers to the importer. Do not log into the portal in someone else’s name.
Build a supplier index: what each party did and which documents sit under that name. Send English translations with the originals.
If a contract, a payment or a transport paper is missing, write what is still out and let the importer ask the port for time. Do not fill the clock with an empty letter.
If the same chain was cleared before, have the importer say so and attach a tracing summary. Port charges follow the contract and the notice — see cargo held at destination.

The Alibaba.com annual fee only buys a storefront file. It has nothing to do with US forced-labor enforcement. Membership still goes to ALIBABA.COM HONG KONG LIMITED. Corpable does not stand as importer and does not file in the portal. Release or exclusion follows CBP’s current handling.

Questions teams actually ask

The forwarder says a Hong Kong letterhead and a no-forced-labor letter will clear the US. Is that right?

No. Customs looks at where the goods were mined, produced or manufactured, and whether a supplier sits on the Entity List. A Hong Kong invoice and a one-page statement do not replace the importer’s tracing file.

The buyer wants us to be importer and to file the UFLPA pack. Can we say yes?

Standing as importer is a separate sentence — see US IOR. Most factories do not keep a US import file. Do not say in chat that you will be importer and guarantee release. You can support documents. The entry and the detention costs sit with the importer.

Can the factory send the supply-chain file to CBP and skip the buyer?

A third party may give documents to CBP, but the importer should be told. Storage on a detention still sits with the importer. Applicability or exception reviews go through the Forced Labor Portal as the importer. Factory papers do not replace that identity.

We are not in Xinjiang. Does that mean we will not be detained?

No. The law covers goods produced wholly or in part in the XUAR, or by an Entity List producer. Inputs, commingled lots and downstream processing can all be asked about. High-priority sectors and the list move. Open the current pages before you ship.

May the showcase say “UFLPA compliant / no Xinjiang content”?

Not without tracing documents that match the shipment. You may say supplier lists, contracts and transport papers can be provided, and that the importer files with Customs. “Certified” will be screenshotted as a promise.

Can Corpable file with CBP or guarantee a shipment will not be held?

No. An advisor can sit with you on the reply and on which papers to gather. We do not stand as importer, file in the Forced Labor Portal, or guarantee release. Outcomes follow CBP’s current handling.
