A factory audit (also called a factory inspection or supplier audit) is an on-site assessment of a Chinese manufacturer's facilities, capabilities, quality systems, and compliance. It is the most reliable way to verify that a supplier is legitimate, capable of producing your product to the required quality, and compliant with your standards. Every significant import order should be preceded by a factory audit — especially for first orders from new suppliers.
Types of Factory Audits
| Audit Type | Purpose | Typical Duration |
|---|---|---|
| Supplier Qualification Audit | Verify factory legitimacy, capacity, and capability before first order | 1–2 days |
| Quality Management System (QMS) Audit | Verify ISO 9001 or similar QMS implementation | 1–2 days |
| Social Compliance Audit (SCA) | Verify labor conditions, wages, working hours, safety | 1–2 days |
| Process Audit | Assess specific production processes and controls | Half to 1 day |
| Environmental Audit | Assess environmental compliance and sustainability practices | Half to 1 day |
| Combined Audit | Multiple audit types conducted simultaneously | 2–3 days |
Factory Audit Checklist
1. Documentation Verification
- Business License (营业执照 — check expiry date, registered capital, business scope)
- ISO 9001 certificate (verify with issuing body)
- Product-specific certifications (CE, FDA, BIS, etc.)
- Tax registration certificate
- Import/export license (if applicable)
- Facility ownership or lease documents
2. Facility Assessment
- Factory size (actual floor space, not just claimed)
- Number of workers (verify payroll records)
- Equipment list (age, condition, capacity)
- Tooling and mold inventory (especially if you've paid for molds)
- Raw material storage conditions
- Finished goods warehouse
- Fire safety equipment and emergency exits
3. Quality Control Systems
- Incoming material inspection (IQC) records
- In-process quality control (IPQC) checkpoints
- Final quality control (FQC/OQC) procedures
- Calibration records for measuring instruments
- Non-conformance and corrective action records
- Customer complaint records and resolution
4. Production Capacity
- Daily/monthly production capacity (request evidence — production records)
- Lead time estimates backed by production schedule
- Sub-contractor use (if any) — verify their quality too
- Shift structure (single/double/triple shift capability)
Red Flags in Factory Audits
⚠️ Red flags that indicate a factory may be unreliable:
- Business license expired or registered under different entity name than trading name
- Factory significantly smaller than claimed (fewer workers, less equipment)
- ISO/CE certificates cannot be verified with the issuing body
- No in-house quality control systems — no QC instruments, no records
- Factory is actually a trading company — no on-site manufacturing
- Workers unable to describe their QC procedures
- Products shown in catalog not actually manufactured on-site
- Previous customers refuse to provide references
- Reluctance to allow unannounced follow-up visits
- Vague answers about sub-contracting arrangements
Frequently Asked Questions
Third-party factory audits in China typically cost: Basic supplier qualification audit (1 day): $300–$500. Social compliance audit (BSCI, SMETA): $500–$800. ISO 9001 gap assessment: $400–$600. Combined audit (quality + social): $600–$1,000. These are fees from audit companies (SGS, Bureau Veritas, Intertek, Elevate). ChinaBajar conducts basic factory qualification audits as part of its supplier verification service. The cost of an audit is minimal compared to the cost of a bad order (typically $5,000–$100,000+ lost).
Virtual factory audits became common during COVID-19 and remain a useful tool. A virtual audit involves: live video tour of the factory via WeChat/Zoom, document sharing screen-share, live worker interviews, and real-time process observation. Virtual audits are less thorough than in-person (you can't physically test materials or inspect equipment up close) but are faster (2–4 hours) and cheaper. They are suitable for: re-auditing existing suppliers, preliminary qualification before an in-person visit, or low-risk product categories. For first-time high-value orders, always prefer in-person.
A social compliance audit (SCA) assesses a factory's labor conditions, worker rights, wages, working hours, health and safety, and environmental practices. Common frameworks: BSCI (Business Social Compliance Initiative), SMETA (Sedex Members Ethical Trade Audit), SA8000, WRAP. These audits check: minimum wage compliance, maximum working hours (≤60 hrs/week), no child or forced labor, fire exits and safety training, worker accommodation conditions, and environmental permits. Many Western brands and retailers (H&M, Walmart, Amazon) require their suppliers to pass social compliance audits. If you're sourcing for a brand or retailer, check which SCA framework they require.
Audit frequency depends on risk level: New suppliers: audit before first order, then re-audit after 12 months. Established suppliers: annual audit or every 2 years if track record is strong. High-risk categories (medical, food, children's products): annual audit minimum. After significant factory events: change of ownership, facility expansion, natural disaster — re-audit. After quality incidents: immediate re-audit. Most brands with significant China sourcing operate a formal supplier audit program with scheduled re-audits. ChinaBajar can manage ongoing supplier audit programs for brands sourcing regularly from China.
