AI-Powered supplier vetting

SummaryThe supplier demonstrates broad customization, 3D design, ODM, and OEM capabilities, supported by 6–10 years of R&D engineer experience and five production lines. Quality and management systems include CCC, ISO9001:2015, ISO14001, and ISO45001:2018 certifications, along with documented inspection, complaint-handling, corrective-action, and traceability procedures. The supplier has substantial export activity, with 71%–90% of sales from exports and markets across five regions. Its service network is primarily domestic: it reports no overseas warehouses, showrooms, agents, or branches, and offers services in zero countries overseas. Innovation evidence is mixed because the supplier provides design and ODM services but reported no new products in the past year and no available SDK. Customer evidence is limited to general statements about OEM and ODM partnerships and does not identify specific customers or cases.

Supplier typeThe supplier operates as an OEM and ODM provider, offering 3D software design and multiple forms of customization. It states that it serves OEM and ODM partners worldwide, while its overseas service infrastructure does not include warehouses, showrooms, agents, or branches.

CertificationsThe supplier reports CCC product compliance certification and ISO9001:2015, ISO14001, and ISO45001:2018 management-system certifications. These explicitly demonstrate documented product and management compliance credentials.

After-Sales capabilityThe supplier has a documented customer-complaint procedure with records, as well as written supplier-service assessment and corrective/preventive-action procedures. However, it reports no overseas warehouses, showrooms, agents, or branches, which limits evidence of localized overseas support.

Production capacityThe supplier operates five production lines and lists punching, assembly, polishing, CNC, riveting, and sharpening equipment. It also reports five quality assurance and quality control inspectors, 21–30 quality control staff, finished-product inspection instructions, and lead times of within 15 working days off-season and one month during peak season.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, flexible customization, 3D software design services, and ODM services. These statements directly establish broad customization capability.
