AI-Powered supplier vetting

SummaryJiahexin is a China-based manufacturer and seller of processing machinery, mechanical equipment, building-material-related products, photovoltaic equipment, and steel-structure parts. It reports ISO9001:2015 certification, five production lines, 11–20 quality-control staff, and stated steel-structure capacity of 100,000 tons. The supplier supports sample-, design-, and fully customized production and has valid manufacturing-capacity contracts with affiliated subcontractors. It reports 90% export sales and 10 years of export experience, but lacks overseas warehouses, showrooms, agents or branches, and has not participated in offline trade shows. Quality procedures, complaint handling, and corrective/preventive-action records are stated to exist. Financial information is limited to year labels without substantive financial metrics, while customer evidence consists only of general claims of positive feedback.

Supplier typeThe supplier operates across processing machinery manufacturing, mechanical equipment sales and R&D, building-material-related products, photovoltaic equipment manufacturing and services, and steel-structure production. Its factory is located in Jiaozhou, Qingdao, China, with five production lines and stated steel-structure output of 100,000 tons.

CertificationsThe supplier explicitly reports an ISO9001:2015 certificate and states that quality assurance exists within its quality-control processes. The provided information does not include certificate scope, issuing body, or validity dates, but the stated certification is positive evidence.

After-Sales capabilityThe supplier has stated procedures and records for handling customer complaints and corrective/preventive actions. However, it has no overseas warehouse, showroom, agent, branch, or stated overseas service-country coverage, limiting evidence of localized after-sales support.

R&D capabilityThe supplier reports R&D capability with an available SDK and lists mechanical-equipment R&D, industrial engineering design services, photovoltaic technology services, and technical development activities in its business scope. The evidence supports the existence of technical and R&D functions, but does not quantify patents, R&D investment, products developed, or engineering depth beyond three years of total R&D engineer experience.

Production capacityThe supplier reports five production lines, 11–20 quality-control staff, 100,000 tons of steel-structure parts capacity, inventory capability, and valid manufacturing-capacity contracts with affiliated subcontractors. These stated resources indicate established production capacity, although the combined facility names are classified and detailed capacity verification is unavailable.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, and full customization. This directly demonstrates broad stated customization coverage for customer requirements.
