AI-Powered supplier vetting

SummaryKaiyu is presented as a China-based manufacturer of pumps, hydraulic pipe fittings, machinery accessories, and automotive/motorcycle accessories, with OEM experience for recognized brands and customization based on samples, drawings, and customer requirements. ISO9001/ISO9001:2015 certification is reported. Quality controls include written inspection instructions, 100% finished-product inspection, raw-material traceability, and documented complaint and corrective-action procedures. Export experience is substantial, with 71%–90% of sales reportedly from exports and 24 years of exporting history. However, the evidence also shows no available SDK, no new products launched in the last year, one production line, limited overseas service infrastructure, no overseas warehouse, showroom, agent/branch, or offline trade-show participation, and inconsistent company-profile details across slices. Customer-specific cases are not provided.

Supplier typeThe supplier is described as a Chinese industrial manufacturer producing pumps, hydraulic pipe fittings, machinery accessories, and automotive/motorcycle accessories. It also reports OEM service for recognized brands, indicating a manufacturing/OEM supplier profile rather than a service-only or trading-only business.

CertificationsThe supplier reports ISO9000 certification in its company overview and an ISO9001:2015 certificate in the certification record. These statements provide explicit evidence of a certified quality-management system, although the certification descriptions are not fully consistent in standard naming.

After-Sales capabilityThe supplier has written and followed procedures for handling customer complaints and corrective/preventive actions, and finished-product inspection instructions are uniformly followed. However, it reports no overseas warehouse, showroom, agent/branch, or overseas service coverage, so documented service processes exist but international service infrastructure appears limited.

R&D capabilityThe supplier reports no available SDK and no new products launched in the past year. Although it has two years of R&D engineer experience recorded, the explicit evidence indicates limited demonstrated recent product innovation.

Production capacityProduction evidence includes instrument-lathe and CNC-lathing facilities, mature capacity for non-standard products, raw-material traceability, 100% finished-product inspection, and six quality inspectors in one record. However, another record states one production line and fewer than five quality-control staff, so capacity and staffing data are inconsistent; manufacturing capability is demonstrated but cannot be rated as clearly strong overall.

Customization capabilityThe supplier explicitly offers customization from samples and states that it can design production processes according to customer drawings and requirements. This directly supports customized and non-standard production capability.
