AI-Powered supplier vetting
SummaryDongying Sanhao International Trade Co., Ltd. is a China-based trading company established in 2018 with three employees. It reports its own machining factory, warehouse, and relationships with other Chinese factories, but the available evidence does not establish production scale or independently verified manufacturing capacity. The supplier exports 90% of total sales and has exported for five years, indicating meaningful international trading experience. It offers full customization and ODM services, but has only one R&D engineer, no SDK, and no new products launched in the last year. It has no stated Fortune 500 cooperation, overseas showroom, overseas agents or branches, offline trade-show participation, or overseas service coverage. Financial records are referenced for 2020–2022, but no financial results are provided. Raw-material traceability is unknown, and service-capability assessment relies on relevant records without a written procedure.
Supplier typeThe supplier is explicitly identified as a trading company and limited company based in Dongying, Shandong, China, with three employees. Its description also states that it integrates design, production, trade, and technical services and has an own machining factory and warehouse, but the available information does not change its registered business type.
After-Sales capabilityThe supplier has no overseas showroom, overseas agent or branch, offline trade-show participation, or overseas service coverage, while its stated service proximity is Qingdao Port. It accepts common quotation and payment terms and reports one-month lead times, but these facts do not establish a broader after-sales service network.
R&D capabilityThe supplier has one R&D engineer, no available SDK, and no new products launched in the last year. Although it offers ODM services and full customization, the stated lack of recent new-product output and limited R&D staffing indicate a clear weakness in demonstrated innovation activity.
Customization capabilityThe supplier explicitly provides full customization and ODM services, which directly supports customized design and product-development requirements. This is one of the supplier’s strongest documented capabilities, although only one R&D engineer is reported.
Client casesThe supplier reports no cooperation with Fortune 500 companies and provides no named customer cases or other verifiable reference projects. A repeat-buyer preference of 50%–80% is stated, but it does not identify customers or substantiate specific cases.
