AI-Powered supplier vetting

SummaryHebei Yingrui Imp&Exp Trade Co., Ltd. is a China-based limited company identified as both a trading company and manufacturer/factory, focused on mineral and related insulation and horticultural materials. It reports in-stock capacity, a stated average off-season lead time within 15 workdays, complaint-handling procedures with follow-up records, and broad customization capabilities. Export sales account for 90%, and the company has held self-operated import/export rights for four years. Production information includes vermiculite, perlite, and zeolite output, while the supplier reports 11–20 quality-control staff and 6–10 years of R&D engineer experience. However, no SDK is available, overseas warehouse/showroom/agent capabilities are absent, sustainability compliance statuses are unknown, and the certification entry lists systems without clearly confirming which are currently held. No customer cases are provided.

Supplier typeThe supplier is explicitly classified as both a trading company and manufacturer/factory, with a limited-company structure and no stated affiliation with a larger group. Its listed products include vermiculite, mica powder, perlite, zeolite, white clay calcined, quartz, and sepiolite.

After-Sales capabilityThe supplier has a clear customer-complaint procedure with follow-up records, reports four qualified service-capability suppliers, and states an off-season average lead time within 15 workdays. It also has in-stock capacity, but lacks overseas warehouses, overseas showrooms, and overseas agents or branches, limiting its stated overseas service infrastructure.
