Verification before a first order is not one check but a sequence, and each step in it should leave a document you can test at its source rather than a reassurance you have to believe. The easy half is confirming that a company exists. The half that decides whether your order ships to specification is narrower: which claims can be closed before the deposit, which can only be closed after production, and what you do about the ones that cannot be closed at all.
This page sets out five gates in the order that saves money, the evidence that closes each one, the validity window to read on that evidence, and the answers that should stop the order outright. For the twelve-item desk checklist that runs inside these gates — the questions to ask, the answers that hold up and the answers that should worry you — see our underwear supplier verification checklist.
What “verified” means when the order has not been placed yet
Buyers use one word for three different questions, and a supplier can answer one of them well while failing the other two. Separating them is what makes the process finishable in days rather than weeks.
Three questions buyers conflate
Does the company exist? This is settled by a company-registry lookup and by matching the bank account name to the registered entity. It takes ten minutes, costs nothing, and it fails more often than buyers expect.
Can it make my article? This is a question about scope: which site would run the order, what the social audit of that site covers, which material certificates exist, and whether the test reports name the fabric and colourway you are actually buying.
Will it ship my order to specification? You cannot close this before production, and a supplier who promises to is describing an intention. What you can do before the deposit is contract the evidence: an inspection standard, an inspector, and a balance trigger that depends on the report.
Read together, the three answers set the shape of a first order. Close the first two completely, close the third as far as documents allow, and write the remaining two into the order so that they close themselves. A reliable supplier is not the one that answers all three questions most confidently; it is the one that can close each of them with a document you can check.
Gate 1 — Legal identity, closed before any other document is read
Ask for the exact registered company name and the unified social credit code, then check them on China’s National Enterprise Credit Information Publicity System. The lookup is public and free. What you are checking is not whether the company is impressive, but whether the entity that will invoice you is the entity that exists, at the address it claims, with a business scope that covers apparel and textiles.
Then make three names agree: the name on the registry, the name on the proforma invoice, and the name on the bank account you are asked to pay. They should be identical, character for character. A slight variation — an extra trading word, a different city, a personal name — is not a formatting issue.
The stop condition is specific and worth stating plainly: a personal account, a third-party payee, or account details that change after the proforma invoice has been issued. This is the single most common point at which first-order money is lost, and it has nothing to do with manufacturing capability. A supplier that cannot hold one account name for the length of one order is not a supplier you can build a file on.
Gate 2 — Who actually produces your order
Two structures are legitimate. A factory that owns the site. And a sourcing or supply-chain management company that contracts audited factories and manages the order between them. Both can be verified; ambiguity cannot. The gate closes on one sentence: the address of the site that will run this order, and the social audit that names that site.
If the answer is “our own factory in Fujian” with no site name, you have not received a verification, you have received a claim. Our own answer, for comparison, is that we are a sourcing and supply-chain management company, not a factory: production runs at partner factories in Fujian that hold amfori BSCI audits, and the site report for the producing site is available for the order.
How to read an amfori BSCI audit report
- Read the audited site name and address first, not the trading company at the top of the cover page. The report belongs to a site, and a site is an address.
- Read the audit date against the validity window printed on the report. An audit is a dated snapshot, not a permanent status.
- Read the rating against the findings, and read the open critical findings with the corrective action plan. A report with unresolved findings is information you can use; a report with no findings usually means a narrow scope.
- Read the working-hours section for actual hours recorded, not the policy the site says it applies.
The link between an audit and your order is the site address on the purchase order. If the audit names a site in one province and the order is scheduled elsewhere, the audit is about a different factory — which may be perfectly fine, but then you need the report for the site that will actually run the work.
Gate 3 — Material and article evidence, read for scope rather than for existence
Certificates and test reports are the easiest documents to hold and among the least often read correctly. Three things to read on each one: what article it names, what scope it covers, and when it expires.
OEKO-TEX Standard 100: number, product class, expiry
Ask for the certificate number, then verify it in the OEKO-TEX Label Check rather than accepting a scanned PDF. Certificates are issued for one year, so an expired number is common, and the lookup takes seconds.
Product class decides whether the certificate covers your garment at all. Class 1 covers articles for babies and children up to three years and carries the strictest limits. Class 2 covers articles with direct skin contact. Class 3 covers articles without direct skin contact, and Class 4 home textiles. Underwear is worn next to the skin, so a genuine Class 3 or Class 4 certificate does not cover the use — the number can be real and still not apply.
Test reports: article, colourway, parameters
A report has to name the article and the parameters tested — pH, formaldehyde, azo dyes, colour fastness — and be dated for the material you are buying. A three-year-old report for a different fabric proves the laboratory, not your order. Printed and dyed components carry their own risk: a sublimation print, the elastic and the woven label are separate inputs, and a fabric certificate does not travel automatically to the print.
For chemical limits specifically, the useful question is not “do you have OEKO-TEX” but which parameters were tested, at which limit, on which article. Our page on chemical limits on underwear sets out how REACH, GB 18401, CPSIA and OEKO-TEX divide that question, and our note on audit report versus test report covers why the two prove different things.
Children’s and EU-bound orders add a second layer
For the United States, CPSIA applies to children’s products: ask which laboratory issued the report and whether a Children’s Product Certificate exists for the article. For the European Union, the General Product Safety Regulation (EU) 2023/988 has applied since 13 December 2024, and the importer is the responsible economic operator — which means the responsibility for the file moves to you at the border, not to the factory.
None of this can be produced after the fact by a supplier that never had it. Ask at gate three. A supplier without material certificates usually cannot obtain them for your colourway either, because the certificate follows the material and the factory that buys it.
Gate 4 — Commercial terms in writing, before the sample is cut
First orders fail at this gate more often than at the factory floor, and for a mundane reason: terms get agreed in conversation and then interpreted differently at the moment they matter. Five items are worth fixing in writing before anything is made.
- MOQ per style and per colour, and whether trial pieces count toward the bulk quantity. One number quoted without a per-colour definition is not a minimum, it is an average — and an average is what a first order cannot afford.
- The sample fee, the sample lead time and the credit rule against the bulk order. Agreeing these after the sample means the sample has already set the price.
- Lead time split into sampling, bulk and transit, with the event that starts each clock: sample approval and deposit, not the order date.
- The payment trigger. On FOB sea freight we work on 30% at order confirmation and 70% against a copy of the bill of lading. Where the trade term or the destination requires it, the structure is 30% deposit and the balance paid before shipment, as set out in the quotation and the order confirmation.
- The inspection standard and who books it. AQL to ISO 2859-1, with the level and the inspector named in the purchase order rather than agreed at the end of production.
The Incoterm and the quotation validity belong in this list too. “FOB Xiamen, quotation valid 30 days” is a statement you can hold someone to; “prices are subject to change” is not. Our page on payment terms in China underwear sourcing goes further into deposit and balance structures.
Gate 5 — Contract the evidence before the deposit, not after the shipment
This gate produces no document now. It fixes which document will end the order, which is exactly why it belongs before the money moves.
With a balance against a copy of the bill of lading, payment falls due when the goods are on the water. An inspection carried out after that point supports a claim; it does not control anything. So the inspection has to be booked at purchase-order stage, tied to the AQL written in the order, and its report has to reach you before the container leaves. Our note on arranging a third-party inspection covers who books it and what the report has to contain.
Agree the failure path in writing as well: the rework window, the discount mechanism, or the right to reject. A supplier that will not name a failure path is telling you there is not one.
One detail worth knowing if you are comparing quotations this year: ISO 2859-1 was revised in January 2026. The third edition replaced the 1999 edition, which ISO now lists as withdrawn. A quotation that specifies “ISO 2859-1:1999” is not wrong about the method, but it is citing a superseded edition — worth a question about which version the inspector will apply.
The answers that should stop the order
Four answers are cheap to test now and expensive to discover later. None of them is a judgement about quality; all four are about whether a document will exist when you need it.
- “We have our own factory” with no site address, or an audit report that names a different site from the one scheduled to produce.
- A certificate number that returns nothing in the issuing body’s lookup, or one whose product class sits below the class the garment requires.
- Bank details in a name that is not the registered company, or details that change after the proforma invoice.
- An MOQ that cannot be broken down per colour, combined with a lead time that starts at the order date rather than at sample approval.
When one gate cannot be closed
Three options are honest, and only three.
- Move the risk to the end. If material certificates are missing, keep the balance against the bill of lading and book a pre-shipment inspection. You have not verified the material, but you have kept the money until you can see the goods.
- Shrink the exposure. Place the first order on one colourway instead of four, at the same unit price, so that a specification error costs a fraction of the programme rather than all of it.
- Walk away. When the missing item is legal identity or the account name, no structure makes it safe. This is the one gate where “conditional acceptance” is not a real option.
What does not work is accepting the gap on trust and calling it a relationship. Write the open item into the purchase order as a condition with a date. The difference between a first order and a first loss is usually one clause.
What this looks like on a Unitex order
We are one of the suppliers these five gates are designed to test, and the page is written so that they can be run on us. Xiamen Unitex Trade Co., Ltd. — in the trade since 2009, incorporated in Xiamen in 2013, with capacity across the partner network of 600,000 pcs a month. Underwear MOQ is 2,000 pcs per style per colour, 3,000 for licensed ranges, and 600 sets for sleepwear; trial orders start at 1,000 pcs. Counter samples take 7–10 days on stock fabric, 30 days where the fabric has to be developed, development sampling 12–18 days, pre-production samples 5–7 days, and bulk 45–60 days on a new order against 30–40 on a repeat.
What we hand over at each gate
- Gate 1: registered name and credit code, and a bank account in the same name — the name to match against the proforma invoice.
- Gate 2: the site address that will run your order and the amfori BSCI report for that site, with its audit date.
- Gate 3: the OEKO-TEX Standard 100 certificate number, product class and expiry for the fabric actually used, and test reports naming the article and the parameters.
- Gate 4: MOQ per style and per colour in writing, the sample fee and credit rule, lead times with the event that starts each clock, the payment trigger, the Incoterm and the quotation validity.
- Gate 5: AQL to ISO 2859-1 in the purchase order, a third-party inspection before shipment on request, and the failure path agreed in writing.
It makes no difference whether the order is a custom programme built from your tech pack or an OEM order running a block you already sell — the gates are the same, and in the OEM case gate three matters more, because the block may pre-date the fabric you are now specifying. If you are comparing suppliers, run the gates in order on each of them before comparing quotations. A quotation reflects what a supplier intends. The five gates reflect what it can evidence, and the gap between those two is where first orders are won and lost. Buyers often ask who the best supplier is before they have run the gates; the question cannot be scored until the documents are in, which is the reason to run the gates first. Our page on whether you are dealing with a real manufacturer or a middleman takes gate two further, and the BSCI audit page covers what the social audit does and does not prove for a European order.
What to keep in the file after the deposit
Verification is only useful if the record survives the order. Keep the registry lookup and the account-name match, the audit report for the producing site, the certificate numbers with class and expiry, the test reports naming the article, the signed proforma invoice with the specification attached, the inspection report, and the bill of lading.
Six months later, when a repeat order is quoted at a different number, that file is the baseline that shows what changed — and the reason a repeat order can be quoted at 30–40 days instead of 45–60 is usually that this file already exists.
