# What should you ask a Chinese supplier about raw materials and origin?

[Eldad Shashua](https://www.china-agent.com/blog/author/eldad-shashua)

Ask for names and paper, not promises. For every key input in your order you want the Chinese legal entity that sold it, the one that bought it, and the ordinary-course papers that show the money moved and the goods moved. In English, dated, before CBP ever asks. "Made in China" on a proforma tells you nothing about where the materials inside the box came from.

Why it matters: under UFLPA, any input tied to the Xinjiang Uyghur Autonomous Region (XUAR), or to a party on the UFLPA Entity List, can pull the whole shipment into forced-labor review. The duty stays with you as importer of record. China Agent organizes and verifies the China side. We do not file entries. We do not give US customs legal advice. Confirm current requirements with your licensed broker or customs counsel.

Usually I get this question when the buyer already has a supplier and the PI looks fine. The trading desk says the goods are Chinese. The factory chop is sitting on some brochure PDF. Then somebody on the US side asks where the cotton came from, or the PVC resin, or the aluminum billet, and the WeChat thread goes quiet. That quiet is your real answer, until you turn it into dated questions and dated records.

## "Made in China" on the PI is not where your inputs came from

A country-of-origin claim on finished goods tells you where the last substantial transformation happened, or whatever rule your broker applies for that product family. That's it. It doesn't tell you which Chinese legal entity bought the yarn, the resin, the silica, or the scrap metal, or which warehouse took delivery. And for sure it doesn't tell you if any of those upstream names sits on the [DHS UFLPA Entity List](https://www.dhs.gov/uflpa-entity-list).

CBP's public [UFLPA enforcement FAQs](https://www.cbp.gov/trade/forced-labor/faqs-uflpa-enforcement) are blunt on the presumption. Goods made with any inputs from XUAR are treated as forced-labor goods under the Act. The FAQ on minor or Tier 3 / Tier 4 inputs does not give you a free pass just because the Xinjiang share looks small. Any such input can matter. So a clean PI and a factory visit photo don't close the origin question for materials.

When I sit with a buyer who already has a chain, I turn all of this into one practical ask. Name the legal entities that supplied and moved the key inputs for *this* order. That batch, that production. Then show the ordinary-course papers for those moves. Basically the factory of the factory, and the supplier of the supplier. Marketing talk about "domestic materials" does not answer that ask.

## What CBP's applicability-review papers say you should be asking already

For an applicability review (that's your claim that the goods were *not* sourced wholly or in part from XUAR and are *not* tied to an Entity List party), CBP's FAQs point importers to Operational Guidance Section IV B and D. The ordinary-course document types listed there may include:

- transaction and supply-chain records such as packing lists, bills of lading, and manifests
- parties involved in manufacture, manipulation, and export, with roles and a flow chart
- payment and transportation records for raw materials: origin of the raw materials; invoices, contracts, and purchase orders; proof of payment; physical transfer documents

CBP says that list is not exhaustive. Different products need different depth. High-priority sectors in the public UFLPA materials include cotton, tomatoes, polysilicon, PVC, aluminum, and seafood. Your broker or counsel confirms what your HS family actually needs. I'm not writing you a magic checklist that releases a box.

What I *do* write for clients is the buyer-side question set that those document types point to. Get the answers in writing. Ask for Chinese legal names, not English trading names. Ask for papers that already exist in the ordinary course of business, then get the English translations ready.

**Who bought each key input for this production run?** Ask for the Chinese legal name on the purchase side, the Chinese legal name of the supplier, and the date of the deal. If all you get back is "our partner," you don't have an answer. You have a nickname.

**Where did that input originate?** Ask for the stated origin of the material before it came into your supplier's factory, and for the ordinary-course invoice or contract that carries that claim. If the material went through traders, follow the trail. Ask for every named link you can still reach on paper.

**How did the money move?** Ask for proof of payment that matches those same invoices and contracts, meaning the supplier invoices the factory actually paid for that batch. A PI without a matching payee trail is a story with a hole in it.

**How did the goods move physically?** Ask for packing lists, warehouse or transfer notes, waybills, or similar papers that show the input left one named entity and arrived at the next. Bank proof alone is not a material trail. Money moving is not yarn moving.

**Who manufactured, manipulated, packed, and exported?** Ask for a role map and a simple flow chart of the parties for this shipment. CBP's guidance treats roles and flow as part of the ordinary-course picture. It's not decoration you add at the end.

**Which English translations are ready already?** Ask who will translate, and who will certify the translation quality your counsel wants. A cabinet full of Chinese-only papers fails the clock, even when every paper inside is real.

All of this goes in your file with dates. Who asked, who answered, what they refused, and when. Gaps stay visible. I would rather hand counsel a file with an honest hole in it, named and dated, than a pretty PDF that hides the missing tier. For the wider list of papers buyers get asked to produce, see [10 things CBP will ask you to produce](https://www.china-agent.com/blog/10-things-cbp-will-ask-you-to-produce). For how those papers sit inside a reasonable-care frame, see [reasonable care records for China importers](https://www.china-agent.com/blog/reasonable-care-records-china-importer).

## Screen every name against the DHS list, and date the screen

The importer has to know its chain. That includes screening names against the [UFLPA Entity List](https://www.dhs.gov/uflpa-entity-list) maintained by DHS / FLETF. CBP's best-practice materials tell importers to keep a list of suppliers with roles, keep the supplier aware of UFLPA, keep documents ready, prepare a response plan, and avoid commingling with forced-labor materials.

On the China side, in work you can put a date on, that looks like this.

Ask your supplier for the Chinese legal names of every party that manufactures, manipulates, packs, or exports the goods and the key inputs for your order. Screen those names against the live Entity List. Keep a dated record of the screen: which names, which list version or retrieval date, who ran it, and what matched or came back clean. A new subcontractor or material trader shows up in the middle of the order? Screen again. Last year's PDF screen is not current, so don't treat it like it is.

An English marketplace storefront name is not a legal entity. We wrote about that problem in [The Alibaba name isn't the factory](https://www.china-agent.com/blog/alibaba-name-not-the-factory). The name on the business license should match the top of the PI and the bank details at the bottom. If you only screened the trading name on the PI, maybe you never screened the company that actually touched the goods.

## Commingling and the small-input problem

CBP's best practices tell importers to avoid commingling with forced-labor materials. In plain buyer words: if Xinjiang-origin yarn sits in the same warehouse bin as your "clean" yarn, or a listed entity's resin can get into the same production line with no segregation record, the paper trail for *your* lot gets very hard to defend.

This is where the FAQ point on any XUAR input bites. A small percentage does not automatically save you on the presumption side. So I tell clients to push the supplier on segregation. How do they keep lots separate? What warehouse or production records show the lot you bought? And what happens when there's a material shortage and they have to substitute in the middle of the run?

If the supplier can't explain segregation with ordinary-course papers, write that down as a gap. Don't build a segregation story after the detention notice arrives. That's the wrong time to start writing.

Clear-and-convincing evidence is a different road. That higher bar applies when goods *are* from XUAR or from an Entity List party and you are asking for an exception. Don't mix it up with an applicability review, where you claim the goods were never in that zone. Your counsel draws that line, not me. My job on the China side is to get you honest names and ordinary-course papers before anybody needs either path.

DNA or isotopic testing comes up in buyer conversations like a silver bullet. CBP's public materials treat testing as something that may be considered as part of a total package. It does not replace knowing who bought what and how it moved. I don't sell testing, and I won't tell you a lab report alone clears a file.

## Weak answers vs ordinary-course papers

The weak package looks the same almost every time.

A one-page English letter on company letterhead: "We hereby certify our materials are not from Xinjiang." No Chinese legal names. No invoices. No payment proofs, no transfer documents. Unsigned, or chopped by somebody who is not on the business license.

An unsigned affidavit copied from a template. Nice English. No bank trail behind it.

An English trading name only. The WeChat contact uses one name, the PI uses another, and the business license has a third. Nobody maps them together.

A brochure PDF with a factory gate photo and a quality stamp. Good for sales. Useless as an input origin record.

What I want sitting next to those weak answers is ordinary-course paper: dated purchase orders and contracts with Chinese legal names; commercial invoices for the inputs; bank proofs that the money went to the named payee; packing lists and transport or warehouse documents that show physical transfer; a role map that matches the parties on those papers; English translations ready for counsel or the broker.

Affidavits and certificates can support. They don't replace the spine. If the supplier will only give you the letter, then that refusal goes in your file as a dated fact. When the buyer already has a factory, a [Supplier Reality Check](https://www.china-agent.com/supplier-reality-check) or a deeper [due diligence](https://www.china-agent.com/due-diligence) path is how we start stress-testing identity and papers on the China side. We verify. We do not find you a new supplier.

## The questions can't stop after order one

One round of questions before the first deposit is not a program. Materials change. Subcontractors change. A trader who was clean last quarter can be sitting next to a listed entity this quarter. CBP's own best practices talk about keeping documents ready and keeping a response plan. That only works if somebody on the China side keeps asking between shipments, so the file stays alive after the first order instead of sitting in a drawer.

[Monthly Support](https://www.china-agent.com/monthly-support-packages) is the door for that ongoing China-side work: $995 per month plus a $1,000 setup, for up to three suppliers on the Support tier. If you have more suppliers, the higher Control and China Department tiers are on the same page. What we keep alive is the named entities, the input papers, Entity List screens with dates, and English organization of what the factory actually produces. Gaps stay visible. Your broker files. You certify. We do not get anyone through CBP.

If what you need is a person sitting in that city week after week, that's a separate door: [Employee in China](https://www.china-agent.com/employee-in-china). Monthly Support is supplier control and file work. An employee is a human on payroll in China. Decide which one you are buying, and don't mix the two.

## Limits (read these before you buy anything)

China Agent verifies, prepares, and drafts on the China side. Your licensed customs broker files. You, as importer of record, certify. We do not give US customs legal advice. We do not file entries. We do not promise release of any detained shipment. We do not claim DNA testing, a visit, or a monthly fee clears UFLPA. Confirm current requirements and product-specific asks with your licensed broker or customs counsel. Primary public sources for the forced-labor frame are CBP's [UFLPA Operational Guidance for Importers](https://www.cbp.gov/document/guidance/uflpa-operational-guidance-importers), CBP's [Forced Labor Enforcement Operational Guidance for Importers](https://www.cbp.gov/document/guidance/cbp-forced-labor-enforcement-operational-guidance-importers), the [UFLPA FAQs](https://www.cbp.gov/trade/forced-labor/faqs-uflpa-enforcement), and the [DHS UFLPA Entity List](https://www.dhs.gov/uflpa-entity-list).

## What to do

Put the input and origin questions above into your next message to the supplier, and ask for Chinese legal names for every party that touches materials and goods. Ask for ordinary-course invoices, contracts, payment proofs, and physical transfer papers for the key inputs on the next order. Screen the names you get against the live Entity List and date the screen. Refusals go in the file too. Keep the English translations in the same folder as the Chinese originals. Then hand the organized pack to your broker or counsel before anybody is asking under a detention clock.

If you want that trail kept alive across shipments on the China side, put [Monthly Support](https://www.china-agent.com/monthly-support-packages) on the file at $995 per month plus setup. Or message us on [WhatsApp](https://wa.me/8615322086875), or [book a call](https://www.china-agent.com/booking?hsLang=en).

Ask the supplier about the inputs now, while the goods are still on land.
