AI-Powered supplier vetting
SummaryThe supplier is a limited company with 184 employees, four production lines, a valid import and export license, and approximately 20 years of export experience. It reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications, maintains documented service, corrective-action, complaint-handling, and finished-product inspection procedures, and has in-stock service capability. It provides ODM and OEM services, including for well-known brands, but reports no new product development in the past year and no available SDK. Production controls show weaknesses: there is no valid manufacturing contract with affiliated subcontractors, no outsourcing SOP, and no continuous batch quantity reconciliation. Overseas warehouse and showroom capabilities are unavailable. Financial records are identified for 2021–2023, but the provided information does not include financial results or sufficient evidence to assess financial credibility. Customer cases are not specifically disclosed.
Supplier typeThe supplier is identified as a combined-type company and a limited company, with no larger-company affiliation or offshore company name. It employs 184 people and holds a valid import and export license, indicating an independently operated, legally licensed trading and manufacturing entity.
CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications. These explicitly demonstrate certification coverage for quality, occupational health and safety, and environmental management.
After-Sales capabilityThe supplier has documented and implemented procedures for service assessment, corrective and preventive actions, and customer complaint handling. It also has in-stock capability, but lacks overseas warehouses and showrooms; the documented procedures provide positive evidence for service handling, while the overseas support limitations remain relevant.
R&D capabilityThe supplier reports no available SDK and no new products in the past year. Although it offers ODM services, the explicit absence of SDK availability and recent new-product development indicates insufficient evidence of strong current innovation capability.
Production capacityThe supplier reports four production lines, 25 qualified service suppliers, and stated peak- and off-season lead-time information. However, it has no valid manufacturing-capacity contract with affiliated subcontractors, no outsourcing SOP, and no continuous batch quantity reconciliation, which are explicit production-control deficiencies.
Customization capabilityThe supplier explicitly provides ODM services and OEM services for well-known brands, supporting its ability to handle customized product development and branded manufacturing. Its approximately 20 years of export experience further supports operational familiarity with international customized orders.
