AI-Powered supplier vetting

SummarySuzhou ZJY Trade Co., Ltd. is a China-based trading company established in 2014, focused on filtration products including air, oil, cartridge, gas, and machinery filters. It reports a 133.0 m² manufacturing plant, more than 10 production lines, and factory locations in Jiangsu and Zhejiang, although the company is classified as a trading company and has only seven employees. The supplier states that it supports industrial, construction, vehicle, biotech, hospitality, and defense filtration applications, with collaborative design and technical assistance. Export sales represent 41%–50% of total sales, and exports began in 2021. Reported lead times are within 15 working days in both off-peak and peak periods. Evidence of certifications, independently verified quality systems, detailed after-sales performance, or broad customer references is not provided. One buyer and one trade transaction are listed.

After-Sales capabilityThe supplier states that dedicated technical assistance is available after sales and that engineers collaborate with customers from concept through production. These statements indicate a claimed support capability, but no service staffing, response metrics, warranty terms, or documented service cases are provided.

R&D capabilityThe supplier describes end-to-end filtration expertise, collaborative engineering design, and applications across industrial, vehicle, biotech, hospitality, and defense sectors. One year of R&D-engineer experience is reported, but no patents, new-product records, laboratory resources, or quantified development achievements are provided.

Production capacityThe supplier reports a 133.0 m² manufacturing plant, factory locations in Jiangsu and Zhejiang, more than 10 production lines, and production covering multiple filter categories. It also states lead times within 15 working days in both off-peak and peak periods; however, its legal business type is trading company and the stated facility area is relatively limited, so the overall manufacturing scale is not fully verifiable.

Customization capabilityThe supplier explicitly claims collaborative design in which engineers work with customers to address specific challenges, alongside application-specific filtration solutions. This supports a stated customization capability, although no customized product examples, tooling details, or project results are supplied.
