Supplier verification is the process of confirming a manufacturer is legitimate, capable, and compliant before placing an order. A factory audit is a structured on-site assessment of the factory's people, processes, equipment, and documentation. Together they are the most important risk management steps in global procurement.
Why Supplier Verification Is Non-Negotiable
The Alibaba era made it easy to find suppliers. It did not make it easy to find good ones. The platform contains verified manufacturers, trading companies posing as manufacturers, subcontractors with no production capability, and outright fraudulent listings. Without verification, buyers cannot distinguish between them.
The consequences of placing an order with the wrong supplier are severe: goods produced by a subcontractor to lower standards, payment made before defects are discovered, inability to enforce warranty or replacement, and in some cases — outright theft of the order deposit with no goods delivered.
Verification does not eliminate all risk. It reduces it to a level that experienced procurement professionals operate at every day.
Step 1 — Basic Document Verification
Before any factory visit or audit, verify the following documents. These are obtainable from the supplier and verifiable through official Chinese government databases.
- Business License (营业执照): Confirms the company is legally registered. Check company name, registration number, registered capital, and business scope — the business scope must include manufacturing or trading of the relevant product category.
- Export License: Confirms the company is authorized to export goods from China. Some product categories require a specific export license.
- ISO / CE / FDA Certificates: If claimed, verify these directly with the issuing certification body — not just by reviewing the certificate provided by the supplier.
- Bank account details: Verify the bank account name matches the registered company name exactly. Discrepancies are a fraud risk.
Types of Factory Audits
Evaluates the factory's quality control processes, procedures, equipment, and team. Assesses whether the factory can consistently produce to specification. Used for most product procurement decisions.
Confirms the factory has the equipment, workforce, and capacity to produce your specific product at the required volume and quality. Prevents the subcontracting problem — factories taking orders they cannot fulfil themselves.
Assesses working conditions, labour practices, health and safety, wages, and hours against international standards (BSCI, SMETA, SA8000, Sedex). Required by many retailers and institutional buyers.
Evaluates environmental management practices, waste handling, emissions, and regulatory compliance. Increasingly required for ESG-compliant supply chains.
Reviews available financial indicators to assess supplier stability. Prevents orders placed with factories that may not survive to deliver — particularly relevant for long production lead times and large advance payments.
Factory Audit Checklist — Key Assessment Areas
- Factory size, headcount, and production departments
- Primary machinery and equipment — condition and relevance to your product
- Quality control equipment and laboratory testing capability
- Raw material sourcing and incoming goods inspection process
- Production floor organisation and cleanliness
- Subcontracting practices and policies
- Defect rate tracking and corrective action process
- Certifications held and current validity
- Workers: skill level, turnover, training records
- IP protection measures: NDAs, access controls, IP segregation
- Fire safety, emergency procedures, and basic H&S compliance
- Prior client references and order history
- Reluctance to share business registration documents or certifications
- Factory address differs from registered company address
- No dedicated production equipment for your product category
- Refuses factory visits or insists on meeting at a hotel
- Prices significantly below market — often signals substandard materials or subcontracting
- Requests 100% payment upfront before production starts
- Bank account name does not match company name on business license
- Evasive about the subcontracting question
- Certificate images are obviously digitally altered or cannot be verified with the issuing body
- No previous buyers willing to provide a reference
Remote Factory Audits
Where an in-person audit is not possible, a remote audit can be conducted via video call with a structured checklist, document review, and third-party local agent verification. Remote audits are less thorough than in-person audits — particularly for assessing actual production equipment and floor operations — but are significantly better than no audit at all.
Plutonia conducts in-person audits in China as standard. For markets outside China — Vietnam, India, Bangladesh, Thailand — we coordinate with trusted local audit partners operating to the same assessment standards.
IP Protection and NDA Agreements
Chinese law recognises intellectual property rights, but enforcement is the buyer's responsibility. Key protections include: a signed Non-Disclosure Agreement before sharing product designs or specifications; a tooling ownership agreement specifying that moulds and tooling paid for by the buyer are the buyer's property; and registration of key trademarks and designs in China.
Do not assume that a factory you share designs with will not share them with your competitors. Structure the relationship legally and document ownership of everything paid for.
