The most reliable red flags in a Chinese supplier are a business license that does not match what they claim to make, a price far below every other quote, a request to pay a personal bank account, and a refusal to let anyone visit the factory or inspect an order. Any one of these deserves a hard look. Two or more together is a reason to walk away before you send a deposit.
This guide is written for US Amazon sellers, DTC brands and small importers who find suppliers through Alibaba.com, trade fairs or referrals. Most Chinese suppliers are legitimate businesses. The point is to find the few that are not, and the larger group that are honest but unsuitable, before money moves.
1. The paperwork does not match the pitch
Every registered company in mainland China has a business license carrying an 18-character Unified Social Credit Code. Ask for a clear copy and check three things:
- The company name on the license matches the name on the quote, the contract and the bank account.
- The business scope includes manufacturing or the product category you are buying. A license that lists only trading or import and export is a trading company, whatever the website says.
- The registration record checks out on the government's National Enterprise Credit Information Publicity System, including registered capital, status and registration date.
A very new registration is not automatically bad, but a supplier claiming "15 years of experience" with a company registered last year needs to explain the gap. A supplier who will not send a license at all has answered the question for you.
2. Factory or trading company, and they will not say
Trading companies are not scams. Many are useful, especially for small orders and mixed containers. The red flag is a trader presenting itself as a factory, because you then pay a margin for a relationship you cannot see and cannot control. Signs to watch for:
- Photos of a factory floor that appear on other suppliers' pages (run a reverse image search).
- A product range that is far too broad for one workshop, such as stainless bottles, silicone phone cases and LED lamps from the same "factory".
- Vague answers on machinery, shift patterns and where each process happens.
- An address in an office tower rather than an industrial district.
Our guide on how to find a manufacturer in China covers how to tell the two apart in more detail.
3. The price is too good
Collect at least three comparable quotes on the same specification. If one is 30 to 40 percent under the rest, there are only a few explanations: thinner material, a cheaper grade of component, a missing certification, a different quantity basis or a bait-and-switch planned for after the deposit. Ask the low bidder for a bill of materials and the exact material grade. A genuine supplier can answer. A supplier running a switch will usually dodge.
4. Payment instructions look wrong
Legitimate Chinese manufacturers receive payment into a corporate bank account in the company's registered name. Be careful when:
- You are asked to wire to a personal account or an account under a different name.
- The bank details change by email midway through an order. Confirm any change by phone with a contact you already trust.
- The supplier wants 100 percent up front. A common structure for a custom order is a deposit at order and the balance after inspection, before the goods leave the factory. Full prepayment removes your only leverage.
- The supplier is pushing you off Alibaba.com's payment system to avoid its buyer protections. Sometimes there is a benign reason, but treat it as a prompt to verify, not a convenience.
5. They resist samples, visits and inspection
A supplier confident in its product welcomes scrutiny. Be cautious when a supplier:
- Offers only stock photos and refuses to send a pre-production sample.
- Sends a flawless sample, then makes bulk production from different materials. Keep the approved sample sealed and signed so it can be compared with bulk.
- Declines a factory visit, a video walk-through or a third-party audit.
- Objects to pre-shipment inspection, or insists the goods "must ship immediately".
Inspection resistance is one of the strongest single signals. It is the check that decides whether you release the balance payment, and an honest supplier has no reason to avoid it. For how inspection levels work, see our quality inspection service.
6. Communication patterns that should worry you
- Answers that do not address your question, or copy-pasted replies that ignore your specification.
- Pressure tactics: "price valid today only", "only 3 units of capacity left this month".
- Reluctance to put technical points, tolerances and packaging in writing.
- A salesperson who cannot connect you to anyone in production or quality control.
7. Compliance answers are vague
If your product is sold in the US, the supplier must understand the rules that apply to it. Children's products fall under CPSIA and ASTM F963, food-contact items under FDA rules, and radio-emitting electronics need FCC authorization. Ask for test reports from an accredited lab, with the report date, the sample tested and the standard referenced. A certificate with no report behind it, or one issued for a different product, is a flag. Amazon can remove listings on documentation grounds, so weak compliance is a sales risk and not only a legal one.
What to do when you spot a flag
A single flag is a question, not a verdict. Put it to the supplier in writing and watch how they respond. Then verify independently:
- Check the registration record against the business license.
- Ask for a live video tour of the production line, not a recorded one.
- Order samples and compare them with a second supplier's.
- Use a third party to confirm the factory exists and makes what it claims.
- Never pay a deposit before steps one to four are done.
Our supplier verification service does steps one, two and four for you. A records and desk audit takes about three days, and adding an on-site visit brings the full process to seven to ten days. Compared with a lost deposit on a first order, that is a small cost.
