AI-Powered supplier vetting
SummaryQINGDAO H-QUALITY INDUSTRIES CO., LTD. is identified as both a trading company and manufacturer/factory in China. The supplier reports more than 10 production lines, multiple product-specific annual capacities, 11–20 years of R&D engineer experience, and 11–20 quality-control staff. It states that the company and its factories passed ISO9001-2008 certification and maintains an export history beginning in 2000, with exports representing 51%–70% of sales. Product and trade records show rigging hardware, sleeves, wire rope slings, turnbuckles, chain blocks, and couplings, but the available transaction evidence is limited to a small number of recorded buyers and transactions. Evidence is insufficient to assess after-sales service, financial credibility, customization capability, or a broad customer track record.
Supplier typeThe supplier is explicitly classified as both a trading company and a manufacturer/factory, with a limited-company structure and an operating location in Shandong, China. This supports a hybrid manufacturing and trading business model.
CertificationsThe company states that it has passed ISO9001-2008 certification, and the same certification is reported for the company and its factories. This is explicit evidence of a quality-management certification, although no other certifications are provided.
R&D capabilityThe supplier reports 11–20 years of total R&D engineer experience and describes an R&D team comprising 3 professor-level senior engineers, 6 senior engineers, and 12 engineers. This directly supports substantial technical and R&D resources.
Production capacityThe supplier reports more than 10 production lines, product-specific annual capacities including 1,200 tons of rigging hardware and 400 tons of wire rope slings, and equipment such as punching machines, heat-treatment equipment, vacuum annealing furnaces, and an automatic plastic-coating line. These details provide explicit evidence of manufacturing infrastructure and measurable production capacity.
