Factory audits are systematic on-site assessments that verify a Chinese supplier’s production capabilities, quality systems, and compliance status. When it comes to China sourcing, according to SGS’s 2026 Global Audit Report, 40% of supplier claims don’t match actual capabilities, making factory audits essential for importers. In this guide, you’ll learn the complete factory audit checklist with 8 assessment areas, scoring methodology, and best practices for 2026.

For importers sourcing from China, factory audits prevent capability gaps, quality issues, and compliance risks. When it comes to China sourcing, this comprehensive guide covers audit types, preparation, execution, and reporting.

How to avoid: Use semi-announced (general timeframe) or unannounced audits for accurate assessment.

❌ Mistake #2: Skipping Documentation Review

Why it’s costly: Paperwork discrepancies reveal systemic issues. When it comes to China sourcing, 25% of quality problems show in documentation first.

How to avoid: Request documents before visit. When it comes to China sourcing, cross-check records during on-site inspection.

❌ Mistake #3: Not Interviewing Workers

Why it’s costly: Workers reveal operational realities that management hides. When it comes to China sourcing, 40% of compliance issues found through worker interviews.

How to avoid: Conduct private worker interviews. When it comes to China sourcing, ask about hours, wages, safety, and conditions.

❌ Mistake #4: Rushing Through Production Areas

Why it’s costly: Production floor reveals true capabilities. When it comes to China sourcing, rushed audits miss 20-30% of capability issues.

How to avoid: Allocate minimum 2-3 hours for production floor inspection. When it comes to China sourcing, observe actual processes.

❌ Mistake #5: No Follow-Up on Findings

Why it’s costly: Audit findings without follow-up are wasted. When it comes to China sourcing, 50% of identified issues are never corrected.

How to avoid: Require corrective action plans with timelines. When it comes to China sourcing, schedule follow-up audits for major findings.
