RUIDA performs on-site factory audits for every shortlisted supplier — physical verification eliminates the risk of trading companies posing as manufacturers.
Supplier verification is the single most important step in China sourcing. A verified supplier reduces the risk of quality issues, delivery delays, and fraud. This guide provides a practical 10-point checklist for evaluating Chinese suppliers before placing orders.
Why Supplier Verification Matters
According to the China Ministry of Commerce, there are over 30 million registered businesses in China with import-export rights. Among them, not all are actual manufacturers — many are trading companies operating from offices far from production lines. Physical verification separates genuine factories from intermediaries.
10-Point Supplier Verification Checklist
1. Verify Business License
Every registered Chinese company has a unified social credit code (18 digits). Request a copy of the business license and verify:
RUIDA verifies business licenses for every supplier before initiating any engagement.
2. Conduct a Physical Factory Audit
A video call is not sufficient. A physical audit includes:
3. Check Export History
A manufacturer with consistent export volume is less likely to be a front. Request:
4. Test Product Samples
Always request pre-production samples before committing to a full order. Key points:
5. Verify Third-Party Certifications
Certifications should be verified at the issuing body's portal, not accepted at face value:
6. Evaluate Communication Responsiveness
Supplier responsiveness during the verification phase predicts their performance during production:
7. Assess Production Capacity
Verify that the supplier can handle your order volume:
8. Check Export Compliance
Ensure the supplier can legally export your product:
9. Request Client References
A legitimate supplier with export experience should have verifiable client references:
10. Validate Payment Terms
Payment terms are a strong indicator of supplier confidence:

Frequently Asked Questions
Can I verify a China supplier without traveling?
Yes. You can hire a third-party inspection company or a sourcing agent like RUIDA to perform the audit on your behalf. We provide detailed reports with geo-tagged photographs within 48 hours of the factory visit.
What is the cost of a factory audit in China?
Independent factory audit costs vary from $300 to $800 per audit depending on location and scope. RUIDA includes supplier audits as part of our service fee — there is no separate charge for the initial supplier verification.
Are Alibaba Gold Suppliers verified?
Alibaba's Gold Supplier verification is based on business license verification and third-party audits. However, it does not guarantee the supplier is a manufacturer rather than a trading company. Physical audit is still recommended for high-value orders.
Should I verify suppliers from 1688 differently?
1688 is China's domestic wholesale platform. Suppliers on 1688 are primarily Chinese-market focused, which means they are more likely to be genuine manufacturers. However, the same verification checklist applies — always request factory audit before placing large orders.
How often should I re-verify a supplier?
Annual re-verification is recommended. Factories change management, lose capacity, or shift production focus over time. RUIDA provides annual supplier re-audits as a complimentary service for repeat clients.
