AI-Powered supplier vetting

SummaryStardrawing International Trading (Shanghai) Co., Ltd. is a China-based trading company established in 2016, focused on caster wheels and related products. The supplied information indicates access to extensive caster-wheel manufacturing experience, broad product coverage, OEM/ODM activity, export-oriented operations, and multiple international markets. However, several records are inconsistent: current company data lists 23 employees and an 80 m² manufacturing area, while historical group information cites 260 staff and 53,300 m²; the supplier also reports beginning exports in 2023 despite describing earlier international OEM/ODM business. Management-system certification is listed only as “Others,” with no named standard. Evidence supports production, product breadth, and customization potential, while after-sales capability, financial credibility, and formal certification remain insufficiently verified.

Supplier typeThe supplier is explicitly classified as a Trading Company and describes itself as a foreign-trade export subsidiary, while its background also references manufacturing, design, development, and OEM/ODM caster-wheel operations. This indicates a trading-led supplier with stated access to manufacturing capabilities rather than a clearly verified standalone factory.

R&D capabilityThe supplier claims to manufacture, design, and develop caster products, perform OEM/ODM work, and maintain a continuous-improvement and innovation objective. It also reports R&D engineering experience and more than ten production lines, providing positive but largely self-reported evidence of development capability.

Production capacityProduction-related information includes stated annual capacity above five million pieces, more than ten production lines, six to ten quality-control staff, and a broad caster product range. However, current records list an 80 m² manufacturing area and 23 employees, while historical group information cites 53,300 m² and 260 staff, so the exact current manufacturing scale is inconsistent and should be verified.

Customization capabilityThe supplier explicitly reports OEM/ODM work for caster-wheel brands in North America and Europe and offers numerous caster configurations, including polyurethane, PVC, rubber, nylon, steel, cast iron, brass, stainless steel, pneumatic, shock-absorber, furniture, and medical casters. These statements support meaningful customization capability, although specific engineering, tooling, and project-delivery details are not provided.

Client casesThe supplier reports OEM/ODM cooperation with several caster-wheel brands in North America and Europe, and one buyer name and transaction record are listed for Mexico. The cases are not supported by detailed product specifications, order history, references, or independently verifiable customer documentation, so the evidence is limited but positive.
