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 including seaweed extract, water-soluble fertilizer, microbial fertilizer, chelate trace fertilizer, amino acid, and potassium humate.

It reports six to ten quality-control staff, five R&D engineers, export capability, Qingdao Port access, and stated lead times within 15 workdays in both peak and off-peak periods. However, the supplied information does not confirm certifications, formal after-sales arrangements, audited financial strength, or sufficient customer-case detail. One trade record is shown, but this is insufficient to establish a broad customer track record.

Production capacityThe supplier reports a professional production line, five operating production lines, a 600 m² manufacturing plant, 102 employees, and six to ten quality-control staff.
