Quality control (QC) is non-negotiable for hygiene products that come into direct contact with skin. A robust QC system prevents costly recalls, protects brand reputation, and ensures consumer safety. Here are the best practices to implement when sourcing from China.
1. Pre-Production Inspection
Before mass production, verify raw materials and component specifications. Check certificates of analysis for SAP, nonwovens, and adhesives. Ensure that colour, thickness, and odour meet your standards.
2. In-Process Quality Checks
Monitor key production parameters such as machine speed, temperature, and pressure. Conduct random sampling at intervals to check absorbency, leak-proof performance, and seal integrity.
3. Final Random Inspection (FRI)
Use internationally recognised AQL (Acceptable Quality Level) standards (e.g., ANSI/ASQ Z1.4) to sample finished goods. Test for physical dimensions, packaging quality, and functional performance (e.g., rewet, retention capacity).
4. Lab Testing for Safety
Engage accredited third-party labs (e.g., SGS, BV) to test for heavy metals, formaldehyde, phthalates, and microbial contamination. Ensure compliance with target market regulations.
5. Documentation and Traceability
Maintain detailed inspection records and test reports. Ensure the factory has a traceability system linking raw material lots to finished product batches.
