SummarySuzhou Ingesheng Lock Co., Ltd. is a China-based limited company established in December 2021, with nine employees and one production line. It offers cabinet locks, hinges, cabinet accessories, and machined parts, and reports 11 years of industrial lock manufacturing experience at the business level. The supplier provides broad customization and ODM/OEM services, has introduced new products within the past year, and serves domestic and overseas markets. Quality procedures include documented inspection instructions, quality assurance, raw-material traceability, and corrective-action and complaint-handling procedures. However, the supplier has fewer than five quality-control staff, only one production line, no available SDK, no supplier-management-system certification listed, and no ongoing batch quantity reconciliation or outsourcing SOP. Financial information is represented only by years, not substantive performance data, so financial credibility cannot be judged. The audit record identifies BV as the...

Supplier typeThe supplier is identified as Suzhou Ingesheng Lock Co., Ltd., a Chinese limited company established in Jiangsu in 2021. Its listed products are cabinet locks, hinges, cabinet accessories, and machined parts, and the company is described as a combined business entity.

CertificationsThe supplier-management-system certification field is explicitly listed as NIL. Although a BV audit record exists with a stated validity period, the provided information does not identify a certification or clarify the meaning of the audit result, so no certification holding is demonstrated.

After-Sales capabilityThe supplier reports clear procedures and followed records for handling customer complaints, as well as a documented corrective and preventive action mechanism. This directly supports an established after-sales issue-handling process.

R&D capabilityThe supplier states that it had new products during the past year and provides ODM services, while its R&D engineers have two years of total experience. However, it has no available SDK, so the evidence supports product-development activity but not SDK-based development capability.

Production capacityThe supplier operates one production line, has fewer than five quality-control staff, and reports order fulfillment within 15 workdays in both off-peak and peak seasons. Quality assurance, inspection instructions, and material traceability are documented, but the supplier lacks ongoing batch quantity reconciliation and an outsourcing SOP, indicating capable but limited-scale production controls.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. It also reports ODM services and OEM services for popular brands, providing strong direct evidence of broad customization capability.

Client casesThe supplier states that it provides OEM services for well-known brands and exports to Southeast Asia, the Middle East, Europe, and Australia, in addition to domestic markets. These statements indicate brand and market experience, but no specific customer names or case details are provided.
