AI-Powered supplier vetting

SummaryWenzhou Xusheng Machinery Industry and Trading Co., Ltd. is a China-based combined factory and trading business established in 2011, with 26 employees and a sanitary equipment portfolio. It reports substantial export activity, with 71%–90% of sales from exports since 2012, and serves markets across multiple regions. The supplier states that its technical aspects meet international leading levels and GMP requirements, uses advanced Japanese CNC equipment, and maintains inspection equipment, quality control, production capacity, and an after-sales service center. It also states that products can be designed according to customer drawings and samples. However, the provided information does not establish formal certification ownership, financial credibility, documented innovation programs, customer cases, or confirmed overseas service capabilities. Audit information is present, but the audit result is recorded as “0” without an explained evaluation scale.

Supplier typeThe supplier is identified as a factory, with company nature recorded as “工厂,” and its business entity type is “Combined.” It operates in manufacturing from Wenzhou, Zhejiang, China, while its English name indicates both machinery industry and trading activities.

After-Sales capabilityThe supplier explicitly reports having an after-sale service center and an excellent quality control system. However, the materials do not describe service scope, response arrangements, or overseas after-sales coverage, so the evidence supports the existence of a service function but not its overall effectiveness.

Production capacityThe supplier reports strong production capacity, Japanese CNC machinery, automatic equipment, complete inspection equipment, and a quality control system. It also provides stated annual quantities for spray balls, butterfly valves, pipe fittings, check valves, and pumps, indicating established production across multiple sanitary product categories.

Customization capabilityThe supplier explicitly states that it can design products according to customer drawings and samples, directly supporting customization capability. OEM, ODM, and 3D design service statuses are otherwise unknown, so the evidence supports drawing/sample-based customization but not a full range of design services.

We only have 304 and 316L two different materials. 100% inspection on raw material. During production, different materials in different place. After materials are finished, we choose 10% for inspection. If there is 0.1% problem in 10%, then no excuse to go ahead for inspecting 100% of the materials.
