AI-Powered supplier vetting

SummaryJiangsu Elite Lock Industry Co., Ltd. is a China-based combined factory and company enterprise established in 2021, with 39 employees, five production lines, and six to ten quality-control staff. Its stated manufacturing scope includes hardware products, metal chains, springs, locks, and related products. The supplier reports export activity since 2017, with 90% of sales from exports and self-operated import-export rights, although another record identifies domestic markets as its primary export market. BV audit information is provided, but the audit result is recorded as 0 and the report validity ended on 2025-09-01. No supplier-management-system certification is listed. R&D experience, production lead times, and operating scale are documented, while outsourcing, warehousing, overseas showroom, OEM, ODM, SDK, after-sales, and customer-case evidence is unavailable. Financial figures are omitted.

Supplier typeThe supplier is identified as a combined factory and company enterprise, legally a limited company in China, while one record classifies the company nature as a trading company. Its stated business includes manufacturing and sales of hardware, metal chains, springs, and related products, indicating a mixed manufacturing-trading profile.

CertificationsNo supplier-management-system certification is listed. A BV audit record exists, but its evaluation result is recorded as 0 and the stated report validity ended on 2025-09-01; therefore, current certification compliance is not established.

R&D capabilityThe business scope explicitly includes research and development of hardware products, and the supplier reports two years of total R&D-engineer experience. ODM, SDK, and new-product development statuses are unknown, so the breadth and effectiveness of innovation capability cannot be confirmed.

Production capacityThe supplier reports five production lines, six to ten quality-control staff, and manufacturing capabilities covering hardware products, metal chains, springs, locks, and cylinders. It also states order fulfillment within 15 workdays in both off-peak and peak seasons, providing explicit evidence of operating production capacity.
