AI-Powered supplier vetting

SummaryQingdao Jinyu Chemical Co., Ltd. is a limited company offering chemicals and a broad range of chemical, material, additive, pigment, and related products. The supplier reports annual productivity of 500 tons for bromobenzene and 1,000 tons for trichloroacetic acid, and provides multiple forms of customization. However, it has only two employees and two cooperative suppliers. No new products were launched in the last year, no SDK is available, and overseas service infrastructure is absent. Financial records are indicated for 2022–2024, but no substantive financial results are provided. An audit by TUV Rheinland is listed with validity from March 18, 2025 to March 17, 2026, while the audit result is recorded as “0,” without an explained interpretation.

Supplier typeThe supplier is identified as Qingdao Jinyu Chemical Co., Ltd., a limited company with chemicals as its primary product category. Its stated business scope covers chemicals, synthetic and rubber materials, pigments, graphene materials, additives, plastic products, equipment, and import/export activities, and it is not part of a larger company group.

After-Sales capabilityThe supplier reports no overseas showroom, no overseas agents or branches, and no participation in offline trade shows. It lists zero countries with overseas services, although Qingdao Port is identified as the nearest service-related port location.

R&D capabilityThe supplier launched no new products during the last year and reports no available SDK. These are explicit limitations for recent product innovation and SDK-supported development, although no broader R&D assessment is provided.

Production capacityReported annual productivity is 500 tons for bromobenzene and 1,000 tons for trichloroacetic acid. The supplier has two employees and two cooperative suppliers; while the stated product capacities demonstrate production capability for these products, the very small reported workforce limits evidence of broad or highly scalable capacity.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, flexible customization, and minor customization. This indicates a broad stated ability to accommodate different customization requirements.
