AI-Powered supplier vetting

SummaryQingdao Cuishi Plastic Machinery Co., Ltd. is identified as a China-based manufacturer/factory in Shandong, although another record describes the company type as a trading company. The supplier states that it was established in 1999, operates a factory exceeding 10,000 square meters, and has ISO 9001 certification. Its product scope centers on plastic pipe, profile, sheet, board, corrugated pipe, and related extrusion production lines. Reported annual capacity is 100 plastic pipe production lines and 20 plastic corrugated pipe lines, with peak-season fulfillment taking 2–3 months. The supplier claims a one-year free warranty for turnkey equipment, lifelong maintenance and debugging, and technical training. Export capability is indicated by self-operated import/export rights and export activity since 2017, with exports representing 41%–50% of sales. Evidence for innovation, customization, and customer cases is limited; one trade transaction and one associated buyer are recorded, but this does not establish...

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and describes itself as a physical factory integrating research and production, with an industrial facility exceeding 10,000 square meters. However, one record classifies the company nature as a trading company, creating a classification inconsistency that should be verified.

CertificationsThe supplier reports certification under ISO 9001 management systems. This is explicit evidence of holding a quality management certification, although no certificate number, issuing body, or validity date is provided.

After-Sales capabilityThe supplier states that it provides a one-year free warranty for turnkey engineering equipment, lifelong maintenance and debugging, and training for technical personnel. These stated commitments support after-sales capability, although actual service performance is not independently evidenced.

Production capacityThe supplier reports annual productivity of 100 plastic pipe production lines and 20 plastic corrugated pipe lines, operates a factory exceeding 10,000 square meters, and indicates a 2–3 month peak-season fulfillment period. These explicit capacity and facility data support production capability, while the stated 1–3 years of total staff experience is a separate limitation in workforce-experience evidence.
