AI-Powered supplier vetting

SummaryZhejiang Change is a silicone-material manufacturer founded in 2010, with two production bases, one sales branch, more than 80 employees, approximately 50,000 square meters of production facilities, 20 production lines, and stated annual output of about 15,000 tons. Its strengths include established production infrastructure, quality assurance, sample-based customization, written supplier-service assessment procedures with records, and lead times within 15 working days in both peak and off-season periods. However, the investigation identifies no supplier-management-system certification, no raw-material traceability, no effective manufacturing-capacity contract with related subcontractors, no inventory, overseas warehouse, overseas branch, or showroom capability, and no new products launched during the previous year. R&D evidence is limited: there are no stated patents, no available audit documentation, and no ODM, SDK, or recognized-brand OEM services. Customer-case evidence is insufficient.

Supplier typeThe supplier presents itself as Zhejiang Change, a silicone-material company focused on developing silicone materials and serving customers internationally. It was founded in 2010 and operates production bases and a sales branch, indicating a manufacturer rather than a purely trading entity.

CertificationsThe supplier-management-system certification field is explicitly recorded as NIL. No certification is identified in the provided information, so there is no evidence of certification compliance.

After-Sales capabilityThe supplier has procedures for corrective and preventive actions and complaint handling, but no written records for either. It also lacks overseas agents or branches, overseas warehouses, overseas showrooms, and in-stock service capability; however, it offers multiple quotation and payment terms and reports lead times within 15 working days in both seasons.

R&D capabilityThe supplier launched no new products during the previous year, provides no ODM, SDK, or recognized-brand OEM services, has zero stated R&D patents, and lacks design input, output, review, verification, and validation documents for audit. These explicit gaps indicate weak demonstrated innovation capability.

Production capacityThe supplier reports two production bases, 20 production lines, approximately 50,000 square meters of production facilities, 20,000 square meters of warehouses, and annual organic-silicone output of around 15,000 tons. Against these physical and output claims, it has no effective contract with related subcontractors, no inventory capability, and only one quality assurance and quality control inspector; finished-product inspection is conducted by random inspection.

Customization capabilityThe supplier provides customization from samples, and its R&D engineer responsibility includes providing samples according to customer requirements. This supports sample-based customization, although the absence of documented R&D audit materials limits evidence of a broader structured design capability.
