AI-Powered supplier vetting

SummaryQingdao Haidelong Biotechnology Co., Ltd. is identified as a China-based manufacturer established in 2008, with 102 employees, five production lines, a 600 m² manufacturing plant, and products focused on organic and environmentally friendly fertilizers. The supplier reports an R&D team, professional production and sales teams, five R&D engineers, and six to ten quality-control staff. It offers customized services and states that crop applications have improved soil, crop quality, and yield, but no specific customer names or independently verifiable case details are provided. Export activity is supported by self-operated import/export rights, stated export markets, Qingdao Port access, and delivery within 15 working days in both peak and off-peak periods. Certification information and sufficient evidence for financial credibility are not provided. The business profile contains some inconsistent classifications, with one slice describing it as a trading company and another identifying it as a manufacturer.

Supplier typeThe supplier is explicitly identified as a manufacturer and describes itself as engaged in R&D, production, import, and export of fertilizers. However, an associated-company record classifies the company nature as a trading company, creating a classification inconsistency that should be verified.

R&D capabilityThe supplier states that it has an R&D team and develops organic and environmentally friendly new fertilizers, while its product range includes seaweed extract, microbial fertilizer, chelate trace fertilizer, and amino acid products. This supports an identifiable R&D orientation, although no patents, laboratory credentials, or measurable innovation outcomes are provided.

Production capacityThe supplier reports a professional production line, five production lines overall, 102 employees, a 600 m² manufacturing plant, and six to ten quality-control staff. It also states that normal- and peak-season order fulfillment is within 15 working days, providing explicit evidence of operating production capacity and delivery capability.

Customization capabilityThe supplier explicitly states that it can provide customized services according to customer needs. No details are given on customization scope, technical feasibility, minimum order requirements, or implementation process, but the stated capability directly supports this field.
