Verifying a Chinese supplier requires a disciplined approach to business due diligence that prioritizes official documentation over verbal assurances. The most reliable way to avoid scams in China is to demand a copy of the supplier’s 营业执照 (Yíngyè Zhízhào)—their Business License—and cross-reference it with the National Enterprise Credit Information Publicity System. If a potential partner is hesitant to share this information or provides documents that look altered, this is a major red flag. Always remember that legitimate trading companies are registered with the government and have a verifiable footprint that goes beyond a basic website or social media profile.
Validate the Official Business License

The 营业执照 (Business License) is the primary document for any company operating in China. Every legitimate entity has an 18-digit Unified Social Credit Code. You should input this number into the official National Enterprise Credit Information Publicity System website. This government database allows you to see the company’s scope of business, registration date, and current operational status. If the company claims to be a manufacturer but their business scope only lists "trading" or "consulting," you are likely dealing with a middleman rather than a factory. When performing chemical supplier verification in China, ensure the license includes a scope covering the specific hazardous or industrial chemicals you intend to purchase.
Evaluate Payment Security Measures
Scammers often pressure buyers to use unconventional payment methods to avoid traceability. Never send payments to a personal bank account, even if the representative claims it is the company owner's account. Legitimate business-to-business transactions should always be processed via bank transfer to the company’s official corporate bank account, which must match the name on the business license. Avoid platforms that do not offer escrow or purchase protection. While 支付宝 (Alipay) and 微信支付 (WeChat Pay) are convenient for personal expenses, they are not appropriate for large-scale international B2B procurement. If a supplier insists on cryptocurrency or Western Union, terminate the conversation immediately to protect your capital.

Conduct a Video Factory Audit
In the era of remote communication, a physical visit to a facility is ideal, but a live video call is a highly effective secondary screening tool. Ask the supplier to walk you through their production line while on a live video stream. During this call, ask them to show specific machinery, employee workstations, and products with your company's name or a distinct mark present. If they refuse a live video tour or provide pre-recorded, edited footage that looks like it was lifted from a stock website, they may be a facade. A real factory will have a noisy, busy environment that is difficult to fake over a 15-minute live stream.
Verify Trade Show Presence and Certifications
Check if the supplier exhibits at major trade events such as the Canton Fair. Companies that invest in booth space are generally more invested in long-term reputation. Furthermore, request copies of their ISO 9001 certification or industry-specific certificates. Do not just accept the file; verify the certificate number directly with the issuing body. Many fraudulent websites copy logos of prestigious certifications to appear legitimate. Cross-checking these credentials with third-party testing organizations is a standard practice for business due diligence in China.
Performing thorough due diligence on Chinese suppliers is a necessary cost of doing business, as recovery of lost funds is extremely difficult once they leave the country.
