AI-Powered supplier vetting

SummaryXiamen Qianyu Technology Co., Ltd. is a China-based limited trading company established in 2016, focused on cleanroom wipes, nonwoven and industrial wipes, swabs, ESD garments, sticky mats, finger cots, and related products. It reports five production lines, stated product output capacities, ISO 9001 certification at its factory, SGS testing for products, and customization supported by factory equipment and R&D teams. The supplier claims delivery within 15 working days in both peak and off-peak seasons and reports that 90% of sales are exports. However, the company has only four employees, fewer than five quality-control staff, one R&D engineer, and two years of staff experience reported. Evidence of customer activity is limited to one recorded trade transaction and one associated buyer; therefore, customer depth and broader financial credibility remain insufficiently established.

Supplier typeThe supplier is explicitly identified as a trading company and limited company registered in Xiamen, China. Its stated business covers the supply of cleanroom, industrial, ESD, and related products across multiple industries, indicating a product-sourcing and distribution role rather than a clearly established standalone manufacturer.

CertificationsThe supplier states that its factory has been certified to ISO 9001 and that all products are tested by SGS. These are explicit quality-system and product-testing claims, although the provided information does not include certificate numbers, validity dates, or issuing-scope details.

After-Sales capabilityThe company explicitly promises timely after-sales service and invites customers to contact it by phone or email for ordering and product questions. The slices do not provide service staffing, response-time records, warranty terms, or documented after-sales cases, so the operational depth of this capability cannot be verified.

Production capacityThe supplier reports five production lines, stated output for cleanroom wipes, ESD garments, sticky mats, finger cots, and SMT stencil wipes, and a 95.0 m² manufacturing-plant area. It also states delivery within 15 working days in both peak and off-peak seasons, providing explicit evidence of defined capacity and lead-time commitments, although the small facility and limited staffing may constrain scale.

Customization capabilityThe supplier explicitly identifies customization as a strength, attributing it to precise factory machining equipment and professional R&D teams. This directly supports the availability of customization services, though no examples of customized products, minimum requirements, or completed projects are supplied.
