AI-Powered supplier vetting

SummaryQingdao Preco Imp. & Exp. Co., Ltd. is identified as both a trading company and manufacturer/factory in Qingdao, China, with eight production lines, 11–20 years of total R&D-engineer experience, and 6–10 quality-control staff. It reports carbide-burr production of 350,000,000 pieces and exports representing 90% of total sales, with exporting activity recorded since 1993. The supplier states that it accepts processing trade and offers products supported by CE and GS certificates; several management-system certifications are also listed, although the records do not specify certification scope or validity. Its product range covers cutting, measuring, and hand tools, machinery, machine accessories, and work equipment. Evidence supports production, export, and customization-related capabilities, while after-sales capability, financial credibility, and customer cases remain insufficiently documented.

Supplier typeThe supplier is explicitly classified as both a Trading Company and Manufacturer/Factory, while another record describes its company nature as a trading company. Its stated product portfolio spans cutting tools, measuring tools, machinery, machine accessories, hand tools, and work equipment, indicating a combined trading and manufacturing profile, though the exact products manufactured in-house are not specified.

CertificationsThe supplier states that it can supply products with CE and GS certificates and lists ISO 9000, TS 16949, ISO 9001, ISO 22000, BS 25999-2, ISO 20000, and EICC under management-system certifications. The records do not provide certificate numbers, issuing bodies, covered sites or products, or validity dates, so the breadth and current status cannot be independently assessed.

R&D capabilityThe supplier reports 11–20 years of total experience among its R&D engineers and describes a professional technology team. It also offers machine tools, cutting tools, carbide inserts, and solid carbide tools, but the slices contain no evidence of patents, proprietary designs, new-product development results, or measurable R&D investment.

Production capacityThe supplier reports eight production lines, 6–10 quality-control staff, and annual carbide-burr output of 350,000,000 pieces. It is identified as both a manufacturer/factory and trading company, and its products include cutting tools and related equipment; however, capacity for products other than carbide burrs is not specified.

Customization capabilityThe supplier explicitly states that it accepts processing trade in addition to offering ready products. This directly supports a customization or contract-processing capability, although the records do not define the customization scope, minimum order requirements, tooling support, or quality-approval process.
