Who Is HS Biopharmaceuticals?
HS Biopharmaceuticals Inc. is an American raw material supplier specializing in joint-health and connective-tissue ingredients. We have been in continuous operation since 2001, pioneering chondroitin sulfate manufacturing as one of the first producers to limit residual sulfate and chloride to United States Pharmacopoeia (USP) requirements.
Our US headquarters in Carlsbad, California coordinates sales, technical support, regulatory documentation, and warehousing. Our primary manufacturing facility in Jiaxing, China — with a second production site in Fujian — handles production, quality assurance, and research and development.
When you work with HS Biopharmaceuticals, you are working with people who know the material end to end, from raw-material sourcing through analytical testing, and whose primary point of contact is in the United States.

Key Milestones






Commitment to Quality & Compliance
Since achieving ISO certification in 2005, we have maintained an unbroken record of quality and innovation. We identified a critical 5% variance between E-HPLC (enzyme-labeled high-performance liquid chromatography) and CPC (potentiometric titration) in chondroitin sulfate sodium analysis and pioneered its application.
Additionally, HS was the first to control sulfate and chloride levels during manufacturing to meet U.S. Pharmacopoeia standards, ensuring our chondroitin sulfate sodium fully complies with all relevant USP requirements.
