AI-Powered supplier vetting

SummaryWenzhou Huiyi Valve Co., Ltd. is a China-based limited company described as both a trading company and manufacturer/factory, with five employees and a broad valve and pipe-fitting product range. It reports annual stainless-steel valve production of 200,000 pieces, exports accounting for 90% of sales, and broad international export markets. The supplier offers extensive customization, including sample-, design-, and full-customization services. However, it does not provide OEM services for popular brands, has no available SDK, launched no new products in the past year, and reports no inventory, overseas warehouse, or overseas showroom capability. After-sales procedures exist but lack written records. Quality assurance, traceability, environmental compliance, and fire-drill status are not evidenced. An SGS audit record is provided for November 1, 2024 to October 31, 2025, but the evaluation result is recorded as 0, without a stated interpretation.

Supplier typeThe supplier is identified as a limited company in China and is described as both a trading company and manufacturer/factory. Its stated business scope covers valve sales, metal materials, hardware wholesale, and import-export activities, while its product range includes valves, fittings, and pipes.

After-Sales capabilityThe supplier has procedures for corrective and preventive actions and customer complaints, but no written records are maintained. It also reports no inventory service capacity, overseas warehouse, or overseas showroom, limiting evidence of structured or localized after-sales support.

R&D capabilityThe supplier reports no available SDK, no OEM service for popular brands, and no new products launched in the past year. These explicit limitations indicate weak evidence of recent product innovation or technology-development capability.

Production capacityThe supplier reports annual production of 200,000 stainless-steel valves, lead times within 15 working days during off-peak periods and one month during peak periods, and a five-person workforce. It has no stated in-stock service capacity, so manufacturing output is evidenced but operational scale and stock responsiveness appear limited.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, flexible customization, and minor customization. This is direct evidence of a broad range of customization services.
