AI-Powered supplier vetting

SummaryXi'an Homey Technology Co., Ltd. is a China-based manufacturer/factory producing water-treatment equipment and related products, including RO membranes, seawater desalination plants, resin, and FRP tanks. It holds a valid import/export license and reports export sales of 51%–70%, with stated lead times of within 15 working days in both peak and off-season. The supplier offers broad customization and ODM services, but reported no new products in the past year and has three R&D engineers. Service-management controls are weak: no written procedures or records were reported for service assessment, approved suppliers, corrective actions, or complaint handling. Raw-material traceability is unknown, and no evidence of notable-brand OEM work, certifications, or customer cases was provided. Financial information is present only as year references, without sufficient evidence to assess credibility.

Supplier typeThe supplier is identified as a manufacturer/factory and limited company operating in Shaanxi, China. Its stated scope includes production and sales of water-treatment equipment and related products, consistent with the listed RO membrane, seawater desalination plant, resin, and FRP tank offerings.

After-Sales capabilityThe supplier reported no written procedures or records for service-capability assessment, corrective and preventive actions, or effective customer-complaint handling, and no approved-supplier list. Although multiple service quotation and payment terms are accepted and stated lead times are within 15 working days, the documented after-sales management system shows a clear deficiency.

Production capacityThe supplier identifies itself as a manufacturer/factory and states that it produces water-treatment equipment, steel portable toilets, and steel refuse collection houses, with products including RO membranes, desalination plants, resin, and FRP tanks. It also reports lead times within 15 working days in peak and off-season, but production capacity, equipment, and output volumes are not provided.

Customization capabilityThe supplier explicitly lists customization from samples, minor customization, customization from designs, full customization, and flexible customization. It also reports ODM service availability, providing direct evidence of broad customization support.
