AI-Powered supplier vetting

SummaryShandong Meide Import and Export Co., Ltd. is identified as a China-based trading company located in Liaocheng, Shandong, with reported steel-processing, metals, forging, casting, and machinery-part capabilities. The provided information cites ISO9001:2000, SGS, RoHS, TUV, and REACH certifications, cooperation with more than 20 Chinese steel mills, multiple production lines, warehouse inventory, OEM/ODM support, and stated quality-control and customer-service commitments. The supplier reports domestic customers and more than 100 long-term cooperative customers, but the evidence does not provide verifiable named customer cases. Company establishment information is inconsistent: one slice states 2022, while others state 1997. Financial credibility cannot be assessed because financial data is excluded. Innovation capability is also not sufficiently evidenced beyond customization and product development-related information.

Supplier typeThe supplier is explicitly classified as a Trading Company, legally named Shandong Meide Import And Export Co., Ltd., and located in Liaocheng, Shandong, China. Other descriptions also state that it focuses on production and sales and acts as an export or sales agent for local steel mills, indicating a trading-centered business with stated production-related operations.

CertificationsThe supplier states that it has passed ISO9001:2000 quality system certification and that its products have passed SGS, RoHS, TUV, and REACH certification. These are explicit quality and product-compliance credentials, although the slices do not provide certificate numbers, validity dates, or issuing-entity verification.

Production capacityThe supplier reports cold-rolling and hot-rolling lines, 10 production lines, large outdoor and indoor warehouses, stated inventory of 20,000 tons, cooperation with more than 20 steel mills, and product coverage including plates, strips, tubes, rods, profiles, forging parts, and machinery parts. It also reports off-peak lead times within 15 workdays and peak-season fulfillment within one month, providing substantial stated evidence of sourcing, processing, inventory, and delivery capacity.

Customization capabilityThe supplier explicitly welcomes OEM and ODM orders, offers customized help for customer applications, and lists custom metal parts and shaped seamless steel tubes among its offerings. These statements directly support the availability of customization services, although the slices do not specify engineering scope, tooling capabilities, or customization limits.
