AI-Powered supplier vetting

SummaryJinan Sendo Air Conditioning Co., Ltd. is identified as a China-based trading company and manufacturer/factory supplying commercial air-conditioning and chiller products. It reports ISO 9001 and ISO 14001 certifications, a factory location in Shandong, 6–10 R&D engineers by total experience and 6–10 quality-control staff, and exports to multiple global regions. The supplier provides 3D software design, SDK-supported R&D, and several customization options. However, only one R&D engineer is reported, no new products were launched in the previous year, and the available audit record shows an evaluation result of 0 with a validity period that ended on 2025-01-07. Evidence is insufficient to assess after-sales service and customer cases. Sustainability compliance indicators and raw-material traceability are also listed as unknown.

Supplier typeThe supplier is described as both a trading company and manufacturer/factory, with a stated business scope covering air-conditioning, accessories, household appliances, ventilation equipment, and related import/export activities. Its product range includes rooftop units, ducted split units, chillers, and chilled-water air-handling units, while the ownership descriptions are inconsistent between a limited company and a wholly foreign-owned enterprise.

CertificationsThe supplier reports ISO 14001 and ISO 9001 management-system certifications. A BV audit record is also provided, but its stated validity ended on 2025-01-07 and the audit evaluation result is 0, so the audit record does not provide current positive assurance.

R&D capabilityThe supplier identifies itself as a professional technical supplier, offers 3D software design, and has SDK availability. However, only one R&D engineer is reported and no new products were launched last year, which limits evidence of active recent product innovation.

Production capacityThe supplier is identified as a manufacturer/factory with a stated factory location in Dezhou, Shandong, a broad HVAC product range, and 6–10 quality-control staff. These details support manufacturing capability, although the provided production-output figure is excluded from consideration because it is monetary data.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also provides 3D software design services, directly supporting broad customization capability.
