AI-Powered supplier vetting

SummaryHumate (Tianjin) International Limited is a China-based trading company established in 2002, with 25 employees and operations connected to chemicals, agriculture, and food products. Its stated offerings include humic and fulvic acid products, potassium and sodium humate, amino acid fertilizer, EDTA products, seaweed extract fertilizer, and microelement fertilizer. The supplier reports five production lines, 6–10 quality-control staff, annual humate/fulvate capacity of 30,000 tons, and one-month peak and off-peak lead times. It exports primarily to South America, Southeast Asia/Mideast, and Europe, with Xingang Port identified for shipments. However, no supplier management-system certifications are reported, R&D engineer experience is limited to one year, and no customer cases or explicit after-sales or customization evidence is provided.

Supplier typeThe supplier is explicitly identified as a trading company and limited company, with its business activities covering chemicals, agriculture, and food. It has a Tianjin company location while the factory is stated to be in Shenzhou, Hebei, indicating a trading entity associated with a separate production location.

CertificationsThe supplier explicitly reports supplier management-system certification as “NIL.” Therefore, the provided evidence does not show certification holdings and indicates a stated absence of such certifications.

R&D capabilityThe supplier describes its management approach as scientific and its work style as innovative, but its reported total experience of R&D engineers is only one year. The limited R&D-experience evidence does not demonstrate a strong innovation capability.

Production capacityThe supplier reports a 400 m² manufacturing plant, five production lines, 6–10 quality-control staff, annual humate/fulvate productivity of 30,000 tons, and one-month lead times in both peak and off-peak seasons. The factory is located in Shenzhou, Hebei, while the company is based in Tianjin, but the stated production data provides explicit evidence of operating production capacity.
