AI-Powered supplier vetting

SummaryKehua is a gear, gear-reduction, transmission, bearing, and transmission-component supplier with CNC, automatic lathing, and gear-hobbing facilities. It reports raw-material traceability, 100% finished-product inspection, two quality inspectors, product customization, recent product development, ODM services, and OEM service for well-known brands. Service strengths include in-stock capability, lead times within 15 working days in both peak and off-season periods, multiple quotation and payment options, and a service response commitment within 24 hours. However, the supplier reports no valid manufacturing-capacity contract with related subcontractors, no overseas warehouse, showroom, agents, branches, or offline trade-show participation. Certification is described generally as compliance with recognized international standards, but no specific certificate is identified. Financial records are referenced for 2021–2023, without sufficient performance details to assess credibility.

Supplier typeThe supplier operates in gear and gear-reduction manufacturing and sales, transmission manufacturing and sales, high-speed precision gear transmission devices, bearings, and related transmission components. Its Zhangjiagang location is described as providing access to Shanghai’s international transportation hub, supporting logistics and supply-chain operations.

After-Sales capabilityThe supplier reports in-stock service capability, quotation acceptance for FOB, CIF, CFR, and EXW, several payment methods, and lead times within 15 working days in both peak and off-season periods. It also states that inquiries and orders are answered within 24 hours, but it lacks overseas warehouses, showrooms, agents, and branches, limiting demonstrated local or overseas after-sales coverage.

R&D capabilityThe supplier reports that it introduced new products during the past year and provides ODM services, indicating product-development and original-design capabilities. It also reports no available SDK, but SDK availability is not necessarily required for the stated gear and transmission product scope.

Production capacityProduction evidence includes CNC, automatic lathing, and gear-hobbing facilities, raw-material traceability, 100% finished-product inspection, two quality inspectors, inventory capability, and stated lead times within 15 working days. A material control weakness is that there is no valid manufacturing-capacity contract with related subcontractors.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. Its reported ODM service further supports the availability of design-oriented customized production.
