Step 1: Check the Business License Against the Official Registry
Before committing to a supplier, confirming their legal registration is essential. Request a copy of their business license (营业执照) and pay attention to the unified social credit code (统一社会信用代码) – a unique 18-character identifier for every Chinese company.
Visit China’s National Enterprise Credit Information Publicity System (operated by the State Administration for Market Regulation, accessible at www.gsxt.gov.cn). Enter the credit code for a free and official verification. This system will reveal:
- Registration number, legal representative, and registered capital
- Business scope (what the company is allowed to do)
- Date of establishment and annual report filing status
- Any administrative penalties or abnormal operations
Check that the name on the business license matches what your contact uses on Alibaba, Made-in-China, or their own website. If there are discrepancies, proceed with caution.
For additional context—like legal disputes or changes in ownership—utilize commercial databases such as Tianyancha o Qichacha. While these aren’t official government systems, they compile public data along with court records and media mentions. Importivity recommends these checks as part of supplier vetting, and Keensourcing suggests confirming the license on Tianyancha first. Just remember, these databases might not always be up to date, so verify the core record on the government site first.
Step 2: Determine Whether You’re Dealing with a Factory or a Trading Company
Many suppliers in China label themselves as manufacturers, yet some are actually trading companies. Both types can be reliable, but understanding the distinction is crucial for pricing, quality control, and lead times. A factory can show you their production lines, while a trading company typically sources from multiple factories, making consistent quality harder to ensure.
Here are some practical methods to differentiate between the two, based on insights from ChineseCheck:
- Check the business scope. If the license includes “production” (生产), “manufacturing” (制造), or “processing” (加工), it’s a factory. If it lists only “sales” (销售) or “trade” (贸易), it’s a trading company.
- Ask for factory photos and a video call. Request a video tour of the production floor, showcasing specific machines. Many trading companies will hesitate or provide generic stock photos.
- Request VAT invoices from previous sales. A factory can issue value-added tax invoices that detail production costs, while trading companies can only provide invoices for resold goods.
- Check for exclusive rights to products. Trading companies often handle commodity items from various sources; factories are more likely to offer customized products or own tooling.
If the supplier can’t substantiate their production capabilities, treat them as a trading company and adjust your approach accordingly. Many reliable trading companies exist, but you’ll need to audit the actual factory they source from. It’s not uncommon for some suppliers to have a flair for the dramatic when showcasing their facilities.
Step 3: Order and Test Product Samples Before a Deposit
Never pay a production deposit based solely on a product brochure or digital images. A sample is your best assurance that the supplier can meet your specifications.
Request a sample that aligns with your exact needs—materials, dimensions, function, and packaging. Be prepared to cover the sample and shipping costs; reputable suppliers will often provide the sample itself at cost or free for standard products. Once it arrives, conduct a thorough test:
- Fit, form, function – does it perform as expected?
- Materials – ensure they match the specification sheet. If feasible, send it to a lab for basic material composition analysis (this can be arranged through a third-party inspection company).
- Packaging and labeling – is the packaging suitable for export? Does the labeling comply with your target market’s requirements?
- Certification markings – if the sample has a CE, FCC, or RoHS mark, note the certificate number and verify it with the issuing body. Couleenergy’s guide to verifying solar manufacturers emphasizes the importance of certification validation across product categories.
Keep a reference sample sealed and stored, as the bulk shipment must match it. Be wary of “golden samples” that are hand-picked and far superior to production quality. The best safeguard against this is an in-line inspection during production. It’s amusing how some suppliers can whip up a perfect sample but struggle with consistency in bulk orders.
Step 4: Validate Certifications and Quality Systems
Supplier websites often showcase logos for ISO 9001, CE, FCC, RoHS, or industry-specific certifications (such as FDA for food-contact materials or CCC for products sold in China). Some of these may be legitimate; others might be copied or entirely fake.
Verify each certificate using the issuing body’s online database:
- Para ISO 9001, check with the certification body (e.g., ANSI-ASQ National Accreditation Board, or the specific registrar listed on the certificate).
- Para CE marking, the certificate should include a “notified body” number. Look up that number on the European Commission’s NANDO database to confirm its validity and scope.
- Para Comisión Federal de Comunicaciones (FCC), search the FCC ID on the agency’s website.
- Para RoHS, while there’s no central database, the report should come from an accredited lab—verify the lab’s accreditation.
If a supplier is vague about providing certificate numbers or copies, or if the number doesn’t appear in any database, treat it as a serious warning sign. Relish Tech suggests that cross-checking both the business license and certifications is vital before committing to a production order.
Step 5: Conduct a Factory Audit (Before Production Order)
Once you’re satisfied with the sample and the supplier’s registration and certifications, it’s time for a factory audit—ideally before placing an order, not just after. Relish Tech emphasizes the importance of completing this audit before committing to production.
You have a couple of options:
- Low-budget video audit. Ask the supplier for a live video walkthrough of the shop floor. Check staff size, equipment condition, cleanliness, and whether production lines are operational. This method has its limitations; a factory could easily stage a clean area, leaving you with an incomplete picture.
- Third-party on-site audit. Hire a local inspection company to visit unannounced or with short notice. The inspector will assess:
- Staff numbers and skill levels
- Age and condition of equipment
- Whether production lines are active
- Quality management system documentation
- Housekeeping, stock organization, calibrated instruments, safety equipment
TradeAiders’ guide to factory audit red flags highlights signs to watch for: disorganized stock, missing safety equipment, uncalibrated tools, and reluctance to show the production floor. Any of these should make you cautious. Genuine factories are typically cooperative, while trading companies or subpar factories may resist thorough audits.

Step 6: Negotiate Payment Terms and a Written Contract
Once verification is complete, agree on payment terms that offer protection. Common structures include:
- Carta de crédito (L/C) – secure but complex and costly for smaller orders.
- Trade Assurance (on Alibaba) – an escrow-style service that holds payment until you confirm shipment.
- Partial deposit, balance after inspection – negotiate a deposit you can afford to risk, with the balance due only after a successful pre-shipment inspection. Importivity’s supplier vetting process emphasizes evaluating payment terms as part of risk assessment.
The contract (or purchase order) should clearly outline product specifications, reference sample, acceptable quality level (AQL), delivery timeline, packaging requirements, and dispute resolution mechanisms (e.g., binding arbitration at a neutral venue like the Singapore International Arbitration Centre). Verbal promises are not enough; ensure everything is documented.
Step 7: Schedule a Pre-Shipment Inspection (PSI)
Before making the final payment, arrange a third-party pre-shipment inspection. The inspector visits the factory while the goods are being packed or after packing, checking:
- Quantity (count and compare to the packing list)
- Appearance and workmanship (against the reference sample)
- Function – randomly test units
- Packaging and labeling
- Conformity to certification requirements (e.g., correct markings)
Connected Sourcing advocates for final random inspections before shipment as a standard verification step. Many small importers skip PSI to save costs, but it serves as the last checkpoint before your goods leave the factory. Even a PSI can’t catch every defect—hidden flaws in raw materials can slip through—so it’s most effective when combined with earlier steps like factory audits and sample testing.
Limitations and Realistic Expectations
Verification significantly reduces risk, but it doesn’t eliminate it. Language barriers, cultural differences, and the potential for inconsistencies between samples and bulk orders still exist. A factory may pass an audit today and cut corners tomorrow. The most effective approach involves multiple layers of checks: use free or low-cost methods (license, samples, certification) for initial screenings and invest in third-party audits and inspections for larger orders.
For small businesses with tight budgets, focus on the first four steps—they’re low-cost and can help identify most fraudulent or incapable suppliers early. If a supplier refuses to provide a sample or pressures you to pay a large deposit before demonstrating production capabilities, it’s time to walk away.
