AI-Powered supplier vetting
SummaryJRS (Hangzhou) Performance Material Co., Ltd. is a China-based trading company established in 2024 with four employees and a valid import/export license. Its stated business scope covers building materials, composite materials, insulation materials, household goods, hardware, ceramics, sanitary ware, and related products. The supplier reports ISO 9001 certification and an active TUV Rheinland audit record, but the available information does not specify the ISO certificate scope or provide a positive audit evaluation result. It offers sample-based, minor, and flexible customization, while R&D resources are limited to one engineer, with no new products launched in the previous year and no available SDK. The supplier states that it supports problem resolution and has long-term cooperation with famous companies, but no customer names or verifiable case details are provided. Production capacity, raw-material traceability, and financial strength cannot be conclusively assessed from the available evidence.
Supplier typeThe supplier is identified as a limited company and trading company, not part of a larger company group, with four employees and a Zhejiang, China operating address. Its stated scope is primarily sales, distribution, and technology-related services across building materials, composite materials, household goods, and other products, indicating a trading-oriented business model rather than an explicitly documented manufacturing operation.
After-Sales capabilityThe supplier explicitly states that customers can contact it when problems arise and that it will provide a solution and assistance. This supports the existence of a stated response commitment, but no evidence is provided regarding service procedures, response times, staffing, warranty terms, or documented after-sales performance.
R&D capabilityThe supplier has one R&D engineer and reports one year of total R&D-engineer experience, no new products launched in the previous year, and no available SDK. It does state that it conducts new-material technology research and development in its business scope, but the limited team and lack of recent product launches provide insufficient evidence of strong innovation capability.
Customization capabilityThe supplier explicitly reports customization from samples, minor customization, and flexible customization. These stated service categories demonstrate some customization capability, although the scope, technical resources, tooling, and delivery limitations are not specified.
