The supplier reports four production lines, a 77,000 m² manufacturing plant, 10 years of R&D engineering experience, 6–10 quality-control staff, and stated watermelon and melon seed output of 500 tons each. It exports to more than 30 countries and lists ISO 9001:2015 certification. Evidence also indicates experience with multiple seed categories and scientific research on watermelon, melon, sunflower, squash, pumpkin, and vegetable varieties. However, the provided information does not sufficiently establish after-sales procedures, customization services, or named customer cases. Financial credibility is supported by stated AA and AAA industry credit ratings, but the evidence is self-reported and no independent verification is provided.

Supplier typeThe supplier is explicitly identified as a manufacturer, factory, and limited company located in Hebei, China. Its stated operations integrate seed research, production, sales, and service, with agriculture and food as its commercial sector.

CertificationsThe supplier states that it holds an ISO 9001:2015 certificate and is recognized with AA and AAA credit ratings in the seed industry. ISO certification is explicit, although the provided slices do not include certificate scope, issuer, or validity details.

Financial creditThe supplier is recorded as a limited company and reports AA and AAA credit ratings in the seed industry. These ratings provide explicit positive evidence, but the slices do not provide independent verification or broader financial-performance information.

R&D capabilityThe supplier reports integration of scientific research with breeding and production, 10 years of total R&D engineer experience, and research popularization across watermelon, melon, sunflower, squash, pumpkin, and other vegetable seeds. This directly supports established research activity and varietal-development capability.

Production capacityThe supplier reports four production lines, a 77,000 m² manufacturing plant, 6–10 quality-control staff, and annual output of 500 tons of watermelon seeds plus 500 tons of melon seeds.
