AI-Powered supplier vetting

SummaryJiaxing Subo Pipe Industry Co., Ltd. is a China-based limited company in Zhejiang that is identified as both a trading company and manufacturer/factory. It demonstrates professional technical supplier status, product development, ODM and OEM capability, multiple customization methods, inventory capacity, and documented finished-product inspection instructions. ISO9001:2015 certification and recent fire drills are reported. However, it does not provide 3D software design services or an SDK, lacks an effective manufacturing-capacity contract with related subcontractors, and has no overseas warehouse, showroom, agents, branches, or offline trade-show participation. Financial records are referenced for 2022–2024, but the slices do not provide sufficient financial performance detail for a credibility judgment. No specific customer names, projects, or case details are supplied.

Supplier typeThe supplier is identified as Jiaxing Subo Pipe Industry Co., Ltd., a China-based limited company in Zhejiang. Its business classification includes both Trading Company and Manufacturer/Factory in one slice, while another describes the company nature as a trading company, indicating a mixed trading and manufacturing profile.

CertificationsThe supplier reports an ISO9001:2015 certificate. This is explicit certification evidence relevant to quality management, although no additional certification details or environmental impact assessment report are provided.

R&D capabilityThe supplier is identified as a professional technical supplier, reports new products during the past year, and offers ODM and OEM services. Its innovation-related tooling is limited by the stated absence of 3D software design services and an available SDK.

Production capacityThe supplier lists duct production, cutting, packaging, hardware packaging, and duct-accessories packaging facilities, has inventory capacity, and reports 15 qualified suppliers for service capability. Finished-product inspection instructions are available and uniformly followed, but there is no valid manufacturing-capacity contract with related subcontractors.

Customization capabilityThe supplier explicitly supports customization from designs, customization from samples, full customization, flexible customization, and minor customization. These capabilities are stated consistently across the technical and facility-related slices.
