AI-Powered supplier vetting

SummaryChengdu Henbin Refrigeration Co., Ltd. is identified as a Chinese manufacturer/factory specializing in refrigeration equipment, refrigerants, vacuum pumps, and manifold gauges. The company states that it conducts research and development, production, export, sales, and after-sales activities. It reports multiple management-system certifications, more than 10 production lines, 6–10 R&D engineers, and 6–10 quality-control staff. Export activity is substantial in the provided data, with exports reportedly accounting for 90% of total sales, coverage of multiple global regions, and exporting beginning in 2019. The evidence supports production, international trade, and stated after-sales capabilities. However, the slices do not provide sufficient evidence to assess financial credibility, customization capability, or specific customer cases. The stated production-output data contains inconsistent units and should not be treated as independently validated.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory and describes itself as a refrigeration technology company engaged in R&D, production, export, sales, and after-sales. Its stated product range includes HFC, HCFC, and HC refrigerants, refrigeration vacuum pumps, refrigerant gas vacuum pumps, and manifold gauges.

CertificationsThe supplier lists OHSAS/OHSMS 18001, ISO 9000, ISO 9001, ISO 29001, GMP, and ISO 14064 as its supplier-management-system certifications. The slices do not provide certificate numbers, issuing bodies, validity periods, or scope, but they do explicitly state that these certifications are held.

After-Sales capabilityThe company explicitly states that it provides after-sales services as part of its operations. Its background description also states that it exports refrigerants and compressors to various countries and has received praise for product quality and performance, supporting an established service and export orientation, although no detailed after-sales procedures or service response metrics are provided.

R&D capabilityThe supplier states that it focuses on research and development, aims to improve technology, learn international advanced technology, and develop new breakthroughs. It reports total R&D engineer experience of 6–10 years, providing direct evidence of an R&D function, but no patents, new-product records, laboratory capabilities, or quantified innovation results are supplied.

Production capacityThe supplier reports more than 10 production lines, a peak-season order-fulfillment time within 15 workdays, and an off-peak lead time also within 15 workdays. It also identifies R134a production and serves broad export markets; however, the stated annual-output figures use inconsistent or unclear units, so production scale cannot be independently quantified from the slices.
