How to Verify Suppliers in China Before You Wire a Single Dollar

Most of the money lost in first-time importing is not lost to bad products. It is lost to bad counterparties. A buyer sees a competitive quotation, exchanges a few friendly messages, receives a proforma invoice with a bank account attached, and sends a deposit to a company they have never actually confirmed exists in the form it claims. By the time the cargo is late, the specification is wrong, or the phone stops being answered, the money is already sitting in an account that no longer responds to email.

Verification is the cheapest insurance in international trade. It costs a few hundred dollars and about two weeks. It protects a transaction that may run into tens of thousands. This is the sequence I run before any client of mine transfers a deposit to a supplier in China.

Start with the legal entity, not the website

A polished website, a B2B storefront and a WeChat contact prove nothing. The only thing that establishes existence is the business licence (营业执照).

Ask for a clear photograph or scan of the original licence, not a retyped summary. On the licence, read four fields carefully:

• Company name in Chinese. The English trading name on the invoice is often marketing. The Chinese name is the legal identity, and it is the name your contract and your bank transfer must match.
• Unified Social Credit Code — the 18-character identifier that replaced the older registration numbers. This is your lookup key.
• Registered capital and establishment date. A company registered four months ago quoting on a USD 60,000 order deserves a much harder look.
• Business scope (经营范围). This states what the company is legally permitted to do. If the scope reads "sales of hardware products, import and export trade" with no reference to manufacturing or processing, you are speaking with a trading company, whatever their photos suggest.

Take the Unified Social Credit Code and check it against China's National Enterprise Credit Information Publicity System, or a commercial equivalent. You are confirming three things: the entity is active and not flagged as abnormal, the registered name matches the licence, and the establishment date matches what you were told.

Manufacturer or trading company?

Neither is disqualifying. A good trading company with real factory relationships can outperform a mediocre direct factory, particularly on small orders and mixed containers. What matters is that you know which one you are dealing with, because it changes your leverage, your pricing headroom and your quality control approach.

Signals of a genuine manufacturer: a business scope that includes production or processing; a registered address in an industrial zone rather than a commercial office tower; an export licence; the ability to answer detailed process questions without going away to "check with the workshop"; production line video that matches the product they quoted, not a generic showroom.

Signals of a trading company presented as a factory: many unrelated product categories under one brand; addresses in office parks; certificates issued in a different company's name; reluctance to do an unscheduled video call from the production floor.

If they are a trading company, ask openly for the manufacturing partner's name. A confident intermediary will discuss it and explain their added value. Evasion is data.

Confirm the address and the export history

Cross-check the registered address on the business licence against the factory address they give you and against satellite imagery. Industrial buildings look like industrial buildings. If the "factory" resolves to a residential compound or a small office suite, you have a sourcing agent.

Ask for evidence of export activity to markets like yours: redacted bills of lading, packing lists or customs declarations from the last twelve months. You are not reading them for the client names — those should be redacted — but for the ports, the volumes and the product categories. A supplier who has never shipped to West Africa may still be excellent, but their documentation habits, packaging standards and understanding of your port's requirements will need managing.

Certifications

Request the certificates that your product and market actually require — CE, RoHS, FDA, SONCAP, NAFDAC registration where applicable — and then verify them. Every legitimate certificate carries an issuing body, a certificate number and a validity window. Check the number on the issuing body's register. Two very common problems: a certificate issued to a different legal entity, and a certificate that covers a related model rather than the one you are buying. Both look fine at a glance and both fail at your port of entry.

Talk to them properly before you talk about price

An unscheduled video call is one of the most useful verification tools available and it is free. Ask them to walk from the reception area to the production line to the raw material store to the QC bench, in one continuous take, during working hours. Ask them to show the line running your product category. Ask a technical question that a sales agent cannot answer, then ask who they had to consult.

Take notes on what you see: is the line busy or idle, is raw material stacked or bare, is there any visible quality control station at all. A factory with no QC bench has no QC process.

The sample protocol

Pay for your samples. Free samples come from the shelf of best output, and they bias you toward the seller's showcase rather than their average.

Run samples in stages:

1. Reference sample — existing product, confirms baseline capability and finish quality.
2. Modified or pre-production sample — your specification, your material, your tolerances. Inspect this against a written specification sheet, even a one-page one. Photographs are not a specification.
3. Golden sample — the approved reference, signed and sealed, with one copy retained by you and one retained by the factory. Every inspection thereafter is measured against the golden sample, not against opinion.

Keep the courier waybill and the sample invoice. If a dispute reaches arbitration or a payment-platform claim, the paid sample and the signed golden sample are the difference between "the goods are not what I expected" and a documented breach.

Third-party audit and inspection

For any first order above roughly USD 20,000, commission an independent on-site audit from a recognised inspection body or a vetted local inspector. A basic supplier audit typically costs a few hundred dollars and covers legal registration, premises, equipment, capacity, workforce and quality systems.

Then build inspection into the production timeline rather than the end of it:

• Pre-production inspection — verify raw materials and components before the line starts. This is where substitutions are caught while they are still cheap to fix.
• During-production inspection at roughly 20–40% completion — catches systematic defects before the whole run repeats them.
• Pre-shipment inspection at 80–100% packed — AQL sampling against the golden sample and the specification sheet, plus carton marking, packing and quantity checks.

The pre-shipment inspection report should be a condition of your balance payment. That single contractual link converts inspection from an expense into leverage.

Banking and payment structure

Two checks before any transfer, every time:

The bank account name must match the legal entity name on the business licence and on the contract. If the beneficiary is a personal account, a Hong Kong entity you have not verified, or a company with a different name entirely, stop. This is the single most common vector for both fraud and for the email-interception scam in which a legitimate supplier's invoice is intercepted and the account details are altered.

Confirm changed bank details by voice. If a supplier emails you new banking details mid-transaction, call your known contact on a number you already had and confirm verbally. Do not use the number in the new email.

Structuring payment terms

For TT (telegraphic transfer) transactions, a common working structure is a 50–60% deposit with the balance paid before shipment, after inspection, or against agreed shipping documents — which of those three applies depends on the supplier, the product, your transaction history together and how you and the supplier have negotiated the allocation of risk. A first-time buyer with no history should be pushing the balance trigger toward after satisfactory pre-shipment inspection, and should expect to pay a little more or accept a slightly longer lead time in exchange.

First-time buyers should not send a large unsecured deposit without, at minimum: completed verification, an approved paid sample, a signed contract, defined inspection milestones and explicit refund or remedy clauses covering late delivery, quantity shortfall and specification failure. A deposit sent without those things is not a payment term, it is a hope.

For larger or higher-risk transactions, an irrevocable letter of credit at sight is appropriate where it is commercially workable — subject to your bank's willingness to issue, the supplier's bank accepting it, and both parties agreeing a realistic document list. LCs shift risk to document compliance, which is its own discipline: a clean LC with impossible documentary conditions protects nobody. Escrow through a major B2B platform's trade assurance programme is a reasonable middle path for smaller first orders.

Whatever the structure, keep the contract governing the money: unit price and currency, Incoterm and named place, lead time from deposit receipt, inspection standard and AQL level, penalty for late shipment, and the remedy if goods fail inspection.

Red flags worth walking away from

• Beneficiary account in a personal name, or a name unrelated to the licensed entity.
• Bank details changed by email during a live transaction.
• Refusal of a live, unscheduled video walk-through of the production area.
• Certificates issued to a different company, or numbers that do not verify.
• Pricing meaningfully below every other quotation in the same specification. It is almost always a material substitution you have not been told about.
• Pressure to skip inspection "because the schedule is tight".
• A business licence that will not be shown in full, or is shown only as a cropped image.

On B2B platform badges

Gold supplier status, verified badges and years-on-platform are paid or procedural signals. They tell you a company paid for a listing and passed a light check. They do not tell you the entity manufactures your product, holds valid certification, or will still be trading in eight months. Use platforms to find suppliers. Verify them outside the platform.

The final verification checklist

Before the deposit leaves your account, confirm every line:

• Business licence received in full and legible
• Unified Social Credit Code verified on the official register, status active
• Business scope covers manufacture or export of your product category
• Manufacturer vs trading company established and acknowledged
• Registered address cross-checked against factory address and imagery
• Redacted export documents reviewed for relevant lanes and volumes
• Product certificates verified with the issuing body, in the correct entity name
• Live video walk-through completed during working hours
• Paid sample received, inspected against a written specification
• Golden sample signed and retained by both parties
• Third-party audit completed for orders above your risk threshold
• Contract signed: specification, Incoterm, lead time, AQL, penalties, remedies
• Inspection milestones agreed and written into the payment schedule
• Beneficiary bank account name matches the legal entity exactly
• Payment structure agreed: deposit percentage and the defined trigger for the balance

Verification is not suspicion. It is professional practice, and good suppliers respect it — in my experience the strongest factories are the ones that answer these questions fastest, because they have answered them before for buyers larger than you. The suppliers who resist are telling you something important, and it costs you nothing to listen.
