AI-Powered supplier vetting

SummaryQINGHE SANJU TRADING CO., LTD. is a China-based limited company established in 2019, operating from Hebei with 15 employees. The supplier describes itself as an integrated manufacturing and trading company and reports four production lines, a 1,200 m² manufacturing area, milling cutter output of 3,000,000 pieces, and export activity across Africa, Southeast Asia/Mideast, Europe, and North America. It states that 71%–90% of sales are exports and offers FOB, CIF, and CFR quotation terms. The supplier claims export experience, after-sales service, broad product coverage, and cooperation with customers in multiple countries. However, its management-system certification is listed as NIL, and the available information does not substantiate specific customer references, formal innovation programs, or detailed customization capabilities.

Supplier typeThe supplier is identified as a combined business entity and describes itself as an integrated industry-and-trade company providing manufacturing, sales, and purchasing follow-up services. This indicates a hybrid manufacturing and trading model rather than a pure trading-only operation.

CertificationsThe supplier’s certification of management systems is explicitly recorded as NIL. Therefore, no management-system certification is evidenced in the provided information.

After-Sales capabilityThe supplier explicitly claims good after-sales service and describes a range of follow-up services intended to support procurement, distribution, and savings management requirements. These statements provide positive evidence of an after-sales service offering, although no service process or performance metrics are supplied.
