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. The supplier states that it has professional production, R&D, and sales teams, and offers customized services. 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.
Supplier typeThe supplier is explicitly classified as a manufacturer and limited company, while associated-company information identifies wholesale and retail activity. Its stated business focuses on R&D, production, import, export, and agricultural technology services, supporting a manufacturing-oriented supplier profile.
R&D capabilityThe supplier states that it is engaged in R&D of organic and environmentally friendly fertilizers, has an R&D team, and has developed or supplies products such as seaweed extract, microbial fertilizer, chelate trace fertilizer, amino acid, and potassium humate. This provides explicit evidence of product-development activity, although no patents, laboratory facilities, or quantified R&D achievements are given.
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. It also states lead times within 15 workdays during both peak and off-peak seasons, indicating stated operational capacity, though independent verification of capacity and delivery performance is unavailable.
Customization capabilityThe supplier explicitly states that it can provide customized service according to customer needs. No limitations, customization examples, or technical parameters are supplied, but the stated capability directly supports this field.
