AI-Powered supplier vetting
SummaryThe supplier is identified as a manufacturing factory in Jing County, Hengshui City, operating in the manufacturing industry. It provides OEM and ODM services, supports extensive product customization, and has documented procedures for service assessment, corrective actions, and complaint handling. Manufacturing capacity is supported by valid contracts with associated subcontractors, in-stock capability, five qualified service suppliers, and stated lead times of within 15 working days in both peak and off-seasons. The supplier exports 41%–50% of total sales and has self-operated import/export rights. It holds ISO9001:2015, ISO45001:2018, and ISO14001 certifications. However, no SDK is available, no new products were reported in the past year, and overseas warehouse and showroom capabilities are absent. Financial information is insufficient for a substantive credibility assessment.
Supplier typeThe supplier is explicitly identified as a factory located in Jing County, Hengshui City, with the associated companies operating in manufacturing. This indicates a direct manufacturing-oriented supplier rather than a trading-only entity.
CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications, while product compliance certification is listed only as “Others” without details. The documented management certifications are positive, but product certification coverage cannot be fully assessed.
After-Sales capabilityThe supplier has written and followed procedures for service assessment, corrective and preventive actions, and customer complaints. It also reports in-stock capability, five qualified service-capability suppliers, and lead times within 15 working days in both peak and off-seasons; however, it lacks overseas warehouse and showroom services.
R&D capabilityThe supplier offers ODM services and reports broad customization from samples and designs, but it has no available SDK and reported no new products during the past year. The evidence shows design-related capability but also a stated limitation in recent product innovation.
Production capacityManufacturing capacity is supported by valid contracts with each associated subcontractor, in-stock capability, five qualified suppliers, and a range of listed production and testing equipment. Finished-product inspection instructions are available and uniformly followed, with stated lead times within 15 working days year-round.
