AI-Powered supplier vetting

SummaryGuangzhou Eternal Fasteners Technology Co., Ltd is a China-based limited company in Guangdong described as a trading company, manufacturer/factory, and group corporation. It supplies bolts, nuts, screws, rivets, washers, pins, and custom fasteners, and states that its services cover design consultation, manufacturing, and post-sale support. ISO 9001 and ISO 14001 certifications are reported. The supplier indicates a high export-sales share of 71%–90% and accepts PayPal, T/T, and Western Union. SGS conducted an audit, with the reported audit period ending in 2025, but the audit result is not interpretable from the coded value provided. Most operational, R&D, sustainability, traceability, logistics, and customer-reference fields are marked unknown. Therefore, evidence supports product scope, stated customization services, management-system certifications, and international commercial exposure, while several capability areas remain unverified.

Supplier typeThe supplier is identified as a limited company operating in China’s Guangdong province and classified as a trading company, manufacturer/factory, and group corporation. Its business engagement is in industrial equipment and components, with fasteners as the stated product focus.

CertificationsThe supplier reports holding ISO 9001 and ISO 14001 certifications. These explicitly indicate reported quality-management and environmental-management system certification, although no certificate numbers or current validity dates are provided.

After-Sales capabilityThe company states that its services extend from design consultation through manufacturing and post-sale support. However, the specific status of in-stock service capacity, overseas warehouses, overseas showrooms, and overseas agents or branches is unknown.

Production capacityThe supplier is classified as a manufacturer/factory and states that it provides manufacturing for a broad range of fasteners, with services spanning design consultation to production. Nevertheless, manufacturing-capacity contract status is unknown, and the order-fulfillment value is provided only as an unexplained code, so production scale and fulfillment performance cannot be fully assessed.

Customization capabilityThe supplier explicitly offers custom fastening solutions tailored to project requirements and reports support from initial design consultation through manufacturing. Specific private-mold R&D and 3D design capabilities remain unknown, so the existence of customization service is supported but its technical depth is not verified.
