SummaryThe supplier is described as a medium-sized fastener manufacturer integrating R&D, production, and sales, with more than 50 employees, over 50 production machines, more than 10 testing machines, and four production lines. It provides OEM services for well-known brands and supports customization from samples and designs. Quality and service-management procedures are documented and followed, including finished-product inspection, supplier assessment, corrective and preventive action, and complaint handling. However, no SDK is available, and no overseas warehouses, showrooms, agents, branches, or offline trade-show participation are reported. Overseas service coverage is recorded as zero countries, while export-trade experience is represented by three experienced staff. Production quantity reconciliation is not continuously performed for every batch or production run. Financial records are identified for 2021–2023, but the provided information does not establish financial strength.
