AI-Powered supplier vetting

SummaryStardrawing International Trading (Shanghai) Co., Ltd. is a China-based limited trading company established in 2016, with operations in Shanghai and a stated focus on caster wheels and related products. The evidence describes broader group-level manufacturing experience dating from 1999, OEM/ODM activity for North American and European caster brands, and claimed capacity exceeding five million pieces annually. The supplier reports more than 10 production lines, 6–10 quality-control staff, seven years of R&D engineer experience, and one-month off-peak lead times, extending to two–three months during peak season. It accepts several quotation and payment terms and reports 90% export sales across multiple global markets. However, certification details are nonspecific, after-sales capability is not documented, and only one trade transaction is shown in the provided trade record. Conflicting company-scale information appears between the current company profile and group-level historical description, so...

Supplier typeThe supplier is explicitly identified as a trading company and limited company based in Shanghai. Its materials also describe a foreign-trade export subsidiary and refer to group-level manufacturing, caster-wheel design, and development activities, indicating trading and manufacturing-related capabilities but not conclusively that the contracting entity itself owns the described facilities.

R&D capabilityThe supplier describes manufacturing, designing, and developing caster wheels, OEM/ODM work, continuous improvement, and innovation. It also reports seven years of R&D engineer experience, providing positive evidence of product-development capability, although the number of engineers and specific innovations are not stated.

Production capacityThe evidence claims annual production capacity above five million pieces, more than 10 production lines, and rigorous inspections supported by advanced facilities. However, another slice describes a much larger group-level site and workforce than the current profile, while the current profile lists an 80.0 m² manufacturing plant; therefore, substantial production capability is indicated but its attribution to the contracting supplier requires verification.

Customization capabilityThe supplier states that it performs OEM/ODM work for caster-wheel brands and offers a broad range of caster types and accessories, including polyurethane, PVC, rubber, nylon, steel, medical, furniture, and pneumatic casters. These statements directly support product customization and range adaptation, although specific customization processes or minimum requirements are not provided.

Client casesThe supplier claims OEM/ODM service for several caster-wheel brands in North America and Europe, and the trade record identifies one buyer in Mexico associated with one transaction. The evidence indicates some customer and market experience, but it does not provide verifiable customer names for the claimed brand relationships, order history depth, or performance references.
