Factory Selection Process

Every partner factory undergoes a multi-step verification before joining our network. We evaluate not just output capacity, but management systems, compliance track record, and willingness to accommodate buyer-specific requirements.

Step 1: Capability Assessment

Review production lines, equipment, and workforce specialization for the target product category.

Step 2: Compliance Verification

Confirm existing certifications (ISO 9001, BSCI, FDA, LFGB, CE, REACH, Prop 65, FSC) and evaluate audit history.

Step 3: Sample Trial

Request production samples against buyer specifications to validate material quality and finish.

Step 4: Ongoing Monitoring

Annual re-verification of certifications and periodic on-site visits for active partners.

Geographic Distribution

Our partner factories span 7 provinces across China's major manufacturing corridors, where material supply chains, skilled labor, and export logistics are most mature.
