AI-Powered supplier vetting
SummaryShenzhen Sino-Australia Refrigeration Equipment Co., Ltd. is a China-based limited trading company established in 2005, specializing in refrigeration compressors, units, cold rooms, evaporators, condensers, and related components. The supplier states that it provides one-stop refrigeration solutions, accepts customization, and offers after-sales service. It reports ISO9001-2000 approval and export quality certification, with products exported to multiple international regions. Operational information indicates a factory in Huizhou, more than 10 production lines, six years of R&D engineer experience, and fewer than five quality-control staff. Export activity began in 2007, and the company has self-managed import-export rights. However, the provided information does not substantiate financial credibility or identify specific customer cases, and the after-sales capability is supported mainly by the supplier’s own stated service promise.
Supplier typeThe supplier is explicitly identified as a trading company and a shareholding-system company specializing in the trade of refrigeration compressors, freezing equipment, and air-conditioning components. It also reports a factory location and production lines, indicating supplier information includes both trading and production-related activities, but the registered business type remains Trading Company.
CertificationsThe supplier states that its products passed ISO9001-2000 approval and hold Quality Certification for Export. These are explicit certification claims supporting quality-management and export-compliance capability, although no certificate numbers or validity dates are provided.
After-Sales capabilityThe supplier explicitly promises perfect after-sale service and describes an excellent service working team. This supports the existence of a stated after-sales commitment, but the slices do not provide details on service coverage, response times, warranty terms, or service personnel.
Production capacityThe supplier lists multiple refrigeration products under its own CNAU brand and reports a factory in Huizhou, more than 10 production lines, and fewer than five quality-control staff. These details support established production capability, while the relatively small stated quality-control team may indicate limited quality-control staffing compared with the reported production-line count.
Customization capabilityThe company explicitly states that it provides one-stop refrigeration system solutions and accepts customization. This directly supports customization capability, although the scope, engineering process, minimum order requirements, and customization examples are not specified.
