AI-Powered supplier vetting

SummaryEnka Group Co., Limited is identified as a China-based limited company in Shandong, described as a trading company, manufacturer/factory, and group corporation. It supplies auto and truck parts, transportation-related products, construction and hardware items, and other listed products. The supplier reports BSCI, ISO 9001, and QC 080000 certifications, factory locations in Shandong and Ningbo, more than 10 production lines, 11–20 years of R&D engineer experience, and 6–10 quality-control staff. It reports export activity across multiple global regions, exports accounting for 90% of sales, and more than 15 years of production and export experience. However, after-sales procedures, customization resources, and financial credibility are not sufficiently evidenced. Trade records show two transactions associated with a buyer in Sri Lanka for chairs and decorative lights, but these records do not independently establish broad customer performance.

Supplier typeThe supplier is explicitly classified as a trading company, manufacturer/factory, and group corporation, with a limited-company ownership structure and a Shandong, China address. This indicates a mixed trading and manufacturing business profile.

CertificationsThe supplier reports holding BSCI, ISO 9001, and QC 080000 management-system certifications. These stated certifications provide explicit evidence of formal compliance and quality-management systems, although the slices do not provide certificate numbers, scopes, or validity dates.

R&D capabilityThe supplier states that it prioritizes sustainable innovation and reports 11–20 years of total R&D engineer experience. These statements support some innovation-related capability, although no specific patents, proprietary technologies, new-product development results, or R&D facilities are provided.

Production capacityThe supplier reports factory locations in Shandong and Ningbo, more than 10 production lines, 6–10 quality-control staff, and over 15 years of production experience. It also describes itself as a manufacturer/factory and reports broad auto/truck parts production, providing explicit evidence of substantial production capability.

Client casesThe supplier states that auto/truck spare parts have been exported to more than 30 countries and regions, including the United States, European Union, Southeast Asia, Africa, and the Middle East. Trade records identify one buyer associated with two transactions in each of two product categories; these records support some transaction history but do not provide enough verified customer cases to assess customer breadth or satisfaction.
