AI-Powered supplier vetting

SummaryA&T Industry Co., Ltd. is a China-based trading company established in 2009, with six employees and an address in Qingdao, Shandong. Its stated product scope covers castings, forgings, stampings, machined parts, plastics, and related industrial components. The supplier reports more than 10 production lines, 6–10 quality-control staff, and production capacities of 2,000 tons each for casting and forging and 500 tons for stamping. It states that it has self-operated import/export rights, serves multiple overseas regions, and accepts FOB, CIF, and CFR quotation terms. However, the records also identify the company as a trading company, while manufacturing capability and staffing information is inconsistent across slices. No certification records, formal after-sales policies, or clear R&D resources are provided. Customer evidence is limited to several 2025 shipments of car air fresheners involving two buyers.

R&D capabilityThe supplier reports total R&D-engineer experience of 1 year, while its product description lists multiple processes including casting, forging, machining, stamping, and injection molding. The limited stated R&D experience does not provide explicit evidence of strong innovation capability.

Production capacityThe records state more than 10 production lines, quality-control staffing of 6–10 people, and annual capacities of 2,000 tons for casting, 2,000 tons for forging, and 500 tons for stamping. However, the supplier is also classified as a trading company, so the information supports stated production coordination or access but does not clearly prove direct factory ownership.

Customization capabilityThe supplier lists tooling options, packaging options ranging from bulk to retail-ready, testing services, and a broad range of casting, forging, stamping, machining, and plastics processes. These details explicitly support the ability to offer varied product and packaging configurations.

Client casesThe records show 2025 shipments of gel-type car air fresheners to Pakistan involving KHURRUM ENTERPRISES and CAR CARE COMPANY. These are concrete buyer-linked transaction records, but they cover a narrow product category and only a small number of disclosed customers.
