• Reorder Rate: A high repeat order percentage suggests customer satisfaction and consistent product quality.
• Facility Size & Staff Count: Larger factories (e.g., >1,000 m²) generally indicate scalability and investment in automation.

Quality Assurance: How to Validate Supplier Performance

Even with impressive claims, due diligence is non-negotiable. Implement these verification methods before committing to long-term contracts.

Request Mill Test Reports (MTRs)

MTRs confirm the chemical composition and mechanical properties of the stainless steel used. Always request MTRs for batches to validate grades like 304 (A2) or 316 (A4), which differ significantly in corrosion resistance.

Evaluate Physical Samples

Order samples to test for:

• Tensile strength (minimum 515 MPa for Grade 304)
• Thread accuracy using go/no-go gauges
• Salt spray testing for corrosion resistance (especially important for marine or outdoor applications)

Conduct Factory Audits (Virtual or On-Site)

Audit checklists should include:

• Raw material traceability
• Welding and threading processes
• Final inspection protocols
• Packaging and labeling standards

Many suppliers now offer virtual tours via video conferencing tools, allowing remote verification of operations. Hebei Junchuang Fastener Co., Ltd., for example, supports audit requests and maintains transparent QA documentation, contributing to its 97.4% on-time delivery rate.
