AI-Powered supplier vetting

SummarySijia was established in 2015 in Tianjin and manufactures water-sports products, including waterproof phone cases, swimming bucket bags, beach shoes, wading shoes, water shoes, and non-inflatable swimming rings. It reports OEM service for well-known brands, strategic cooperation with several domestic brands, and international-market entry since 2019 through certification, sampling, and bulk production. Its facilities cover injection molding, cutting, sewing, printing, mixing, punching, slitting, and related equipment, with flexible customization from designs. Average peak- and off-season lead times are within 15 workdays, and in-stock service is available. However, the investigation identifies weak formal controls: no written procedures for service assessment, corrective actions, complaint handling, or several quality-control records; no raw-material traceability; finished products are checked by packing staff; and no valid manufacturing-capacity contract with related subcontractors is reported. Overseas...

Supplier typeThe supplier is a Tianjin manufacturer established in 2015, specializing in water-sports products and reporting OEM service for well-known brands. Its stated activities include production, research and development, and international-market supply, indicating a product manufacturer rather than a purely trading entity.

After-Sales capabilityThe supplier reports no written procedures or records for customer complaint handling, service-capability assessment, or corrective and preventive actions. Although quality assurance is stated, the absence of documented complaint and service processes indicates that formal after-sales management is not demonstrated.

Production capacityThe supplier lists extensive production equipment and reports average peak- and off-season lead times within 15 workdays, in-stock capability, and export sales of 51%–70%. Nevertheless, there is no valid contract with related subcontractors, finished products are checked by packing staff, and quality-control documentation and traceability are weak, so capacity is evidenced but production-control robustness is a concern.

Customization capabilityThe supplier explicitly offers customization from designs, full customization, minor customization, and flexible customization. This directly supports a broad customization capability.

Client casesThe supplier reports OEM service for well-known brands and long-term strategic cooperation with Li-Ning, Xtep, Peak, Jordan, Hongxing Erke, Little Yellow Duck, Yimei Shan, Sanqi, and Kaidilong. These named brand relationships provide direct evidence of customer experience, although the slices do not specify project scope, duration, or independently verifiable references.
