Zhejiang Fengrun Biotech

Zhejiang Fengrun Biotech is a China-based marine bioproducts manufacturer focused on the R&D, production, and sale of glucosamine, chitosan, and related chitin-derived ingredients. Founded in 1996 in Zhejiang Province, the company positions itself as one of the larger Chinese manufacturers of chitin derivatives, with products used across pharmaceuticals, health supplements, food additives, and cosmetics. Its core commercial portfolio includes glucosamine hydrochloride, glucosamine sulfate sodium salt, glucosamine sulfate potassium salt, and N-acetyl-D-glucosamine. The company emphasizes GMP-oriented manufacturing, large-scale production capacity, and marine-sourced raw materials rather than a therapeutic drug development pipeline. Overall, it appears to be a commercial-stage specialty life science ingredients company rather than a clinical-stage biotech developer.
