Verifying a factory means checking its business license against China's state registry, confirming it is a manufacturer rather than a trader, checking certificates and capacity, auditing on site before the balance payment and inspecting the batch, not just the sample. Most of these steps need Chinese and physical presence, which is why importers hand verification to a team in China.
Most wholesale importers assume the hardest part is finding a supplier. In reality, finding someone willing to sell is easy. The hard part is making sure the entity on the other side of the chat is a real factory and not a trading company; that the 20-tonne lot or full container will match the "golden" sample; and that your payment lands in an account that genuinely belongs to the manufacturer.
A mistake at this stage costs money, not time — a lost deposit, a defective batch, or a vanished supplier. Below is the full process our team in China uses: where to look for factories, how to confirm you are dealing with an actual manufacturer, how to run an audit and how to pay without exposing yourself to risk — and an honest account of which parts cannot be done from abroad.
Why verifying from abroad has blind spots
You can work through the checklist below remotely — but only the part that is available in English and through a screen. The problems that cost importers money hide in the rest:
- Documents in Chinese. The business license, its scope of business (经营范围), the state registry and commercial databases such as Qichacha are all in Chinese. A one-character mismatch between license, contract and bank account is already a red flag — but you cannot see it without the language.
- Video proves nothing. Showrooms are rented and production lines borrowed from a neighbour for the length of a call. Only a person on site — ideally without much notice — confirms real production.
- Factories tell foreigners what they want to hear. Capacity, lead times and "our own production" sound different when the conversation is in Chinese, with someone who knows the cluster and the real cost structure.
- You cannot see the batch from abroad. A swap of materials between the golden sample and mass production only shows up at the pre-shipment inspection — in China, before the balance payment.
- Bank details and payment. Confirming that the account really belongs to the licensed factory, and catching a "our bank account has changed" email, is far easier with someone nearby who can call and visit.
We wrote this guide so you understand the criteria and can ask a supplier the right questions. But the conclusion "this factory is real, it is safe to pay" is more reliably reached on the ground.
Factory or intermediary: the key fork in the road
The first question is not "how much does it cost" but "who am I even talking to." Search results and export marketplaces are dominated by trading companies, not factories. The reason is simple: intermediaries speak better English, build better profiles, and make their living precisely by standing between you and the factory.
An intermediary adds 5 to 30% on top of the factory price and — more importantly — strips you of control. When a quality problem arises, you play a game of broken telephone: you message the intermediary, they message the factory, and the factory answers whatever suits it. You see neither the production line nor the real capacity.
This does not mean an intermediary is always a bad thing. For small mixed orders without any Chinese infrastructure, one can be convenient. But if you buy by the container, work to your own specification, or plan repeat shipments, you need direct access to the factory. We break down exactly how to tell a manufacturer from a trader in practice in a separate guide, "Factory or intermediary: how to tell a manufacturer from a trader."
How to distinguish the two before you sign a contract:
- Business scope on the license. On its business license, a factory carries manufacturing terms in the "business scope" field (经营范围) — 生产 (production), 制造 (manufacturing). If the field shows only 销售 / 贸易 (sales / trade), you are dealing with a trader.
- Who answers technical questions. A factory answers on material, tolerances, and technology without pausing. An intermediary "checks with the manufacturer."
- The address. A factory has a production site in an industrial zone. A trader has an office in the business district of a large city.
- Willingness to receive you at the plant. A real factory calmly lets you onto its premises or admits a third-party inspector. A refusal is a signal.
Where to look for factories
Export platforms (Alibaba, Made-in-China, Global Sources). The simplest way in: English-language profiles and convenient search. The downsides are a high share of traders and prices already set for export.
Domestic Chinese platforms (1688.com, Taobao). These are marketplaces where Chinese businesses buy from one another. Prices here are 20–30% lower than export prices, and you reach manufacturers directly. The catch is that the interface is in Chinese only, settlements are in yuan, and registration requires a Chinese bank account and a local address. Entering on your own is hard for a foreign buyer — one of the reasons importers work through an agent with a presence in China.
Industry trade shows. The fastest way to meet factories in person. The Canton Fair is a universal entry point, but specialized events deliver better results by vertical: SNEC and Intersolar for solar panels and storage, Bauma for construction machinery, dedicated cable & wire expos for fiber optics, and metallurgy shows for steel and rolled products. At a booth you can tell at once who is a manufacturer and who is a reseller.
Referrals and sourcing agents. A vetted contact from someone who has already imported from a specific factory saves you months. An agent with a team on the ground covers both the search and the verification at once. The full search process — channels, clusters, an RFQ template and a shortlist — is in our guide on how to find a wholesale supplier in China.
Verifying the business license — the core of the check
Every Chinese company is required to hold a business license (营业执照). The first step of verification is to ask for a scan and check the details. It is free and screens out most problematic counterparties.
What to look for on the license:
- Full legal name — in Chinese. The English name on a website can be anything; the Chinese name is what carries legal weight.
- Unified social credit code (统一社会信用代码) — 18 characters. It is used to look the company up in the state register.
- Registered capital. Very small capital combined with grand promises about capacity is a reason to be cautious.
- Registration date. A company set up a couple of months ago that promises "15 years in the market" has already given itself away.
- Business scope (经营范围) — this is where it is confirmed whether the company is a manufacturer or a trader.
- Legal representative (法定代表人) — the person in whose name the company is registered.
Next, cross-check the data against official sources. The state register is the National Enterprise Credit Information Publicity System (gsxt.gov.cn). Commercial services Qichacha (企查查) and Tianyancha (天眼查) show a company's history, court cases, ownership changes, and related legal entities. A discrepancy between what is on the license and what is in the register is a serious red flag.
Certifications, capacity, and shipment history
The license confirms that the company exists. Next you have to confirm that it can make your specific product in your specific volume.
Certifications. The baseline is ISO 9001 (a quality management system). Product certifications depend on the vertical: IEC and TÜV for solar modules, CE / UL for electrical goods, and mill test certificates against the relevant standard for steel. Ask not just for a picture of the certificate but for the number you can use to verify it with the issuing body.
Production capacity. Concrete figures: monthly output, number of lines, the realistic production lead time for your volume. A factory that can easily "handle" 50 containers a month but cannot state its number of lines is either a reseller or exaggerating.
Export history. Whether the factory has experience shipping to your region and can provide references. A supplier's customs data can be cross-checked through trade-analytics services (such as ImportGenius or Panjiva) — this shows what the company has actually shipped and where.
On-site factory audit
A video call and photographs prove nothing. A showroom can be rented, a production line borrowed from a neighbor for the duration of the filming, and the "own factory" in the video can turn out to be someone else's. The only thing that confirms production is real is physical presence on site.
What an on-site audit confirms:
- the factory exists at the address on the license;
- the equipment belongs to the company and is not rented;
- production is actually running;
- the stated capacity matches reality.
The critical point is the timing of the audit. The check must be done before any large payment, not after. The classic payment structure is a 30% deposit and 70% before shipment; the inspection must take place before you wire that main balance payment. If you cannot travel yourself, hire a third-party inspector or work through an agent with people in China.
Sample versus batch — the most common trap
The most frequent way to lose money is not with a "phantom" fraudster but with a real factory: a quality swap between the sample and the mass-production batch. They send you a perfect "golden sample," you approve it and pay — and what goes into the container is a product made with cheaper material, thinner, with a different component.
Your protection is built like this:
- An approved reference sample. A sample signed and sealed by both parties, against which the batch is later checked.
- A written specification. Material, dimensions, tolerances, and labeling on paper, not "as in the photo."
- Pre-shipment inspection (PSI). An inspection of the actually produced batch using acceptance sampling (AQL) before shipment, rather than taking anyone's word for it.
Payment and protection against fraud
Most financial losses when importing from China are not about defects but about the payment.
Terms. The standard is a 30% deposit and 70% before shipment (or against a copy of the bill of lading). A 100% prepayment to an unknown supplier is not normal practice — it is a risk.
Where to pay. Only to the company's official corporate account whose name matches the business license. The most common fraud scheme is a request to transfer money to the "director's personal account," to a "partner's account in Hong Kong," or to any suddenly appearing third-party account. If the payee does not equal the factory's legal name, stop.
Bank-detail substitution. A separate type of attack is an email saying "our bank account has changed," supposedly from your manager's address. This is often the result of a hacked mailbox. Verify any change of payment details through a separate channel — a call to a known number, not a reply to that same email.
Working through an agent who pays factories in yuan inside China removes part of this risk: you transfer in a familiar currency to a single vetted party, and the agent handles the local settlements with the factories. We have collected the full set of steps to take before wiring a deposit in a separate piece, "Supplier verification checklist before you wire a deposit."
Red flags: a quick checklist
- refusal to provide the business license or the factory address;
- a price noticeably below market ("too good to be true");
- pressure for full prepayment or payment to a personal / third-party account;
- inability to answer technical questions about the product;
- refusal to allow access to the factory or to an independent inspector;
- a mismatch of names between the license, the bank account, the website, and the email domain.
One flag is a reason to ask more questions. Two or more together are a reason to walk away.
Why importers hand verification to us
Finding and verifying a factory closes the entry risk, but deals also fail later — in production, quality control and delivery. Checking on your own makes sense when the product is simple and the deposit small. Otherwise the cost of a mistake — a lost deposit, a defective container, a middleman's margin — is many times the cost of verifying on the ground. Here is what changes when a team in China does it:
- We read everything in Chinese. The license, state registry, court records and related companies — and we catch mismatches that disappear in translation.
- We visit the factory in person. Not a video but a site visit: equipment, lines, people, raw-material stock.
- We check bank details before the first payment. The account must belong to the same legal entity as the license and contract.
- We control the batch, not just the sample. Pre-shipment inspection happens before you pay the balance.
- Experience, not theory. Since 2019: 3,500+ deliveries, a base of 340+ verified suppliers and over $10M in purchasing volume for clients.

Frequently asked questions
Can a Chinese factory be verified remotely?
Partly. Remotely you can check the business license against the registry, request certificates and hold a video call. But real production, capacity and batch quality are only confirmed on site — by your own visit, an independent inspector or a team in China.
Is Alibaba's Verified Supplier status enough?
No. It is a useful first filter, but it confirms the platform profile — not that this particular factory will make your batch to your spec. The license, scope of business, bank details and production still need checking separately.
What if the supplier refuses an audit?
Treat it as a signal. A real factory usually agrees to a visit by the buyer or an independent inspector. A refusal combined with pressure for full prepayment is a reason to look elsewhere.
When should the checks happen?
Twice: company checks and the audit before the first payment or a large deposit, and batch inspection before the balance payment. A check after you have paid protects nothing.
