Shark chondroitin sulfate is a glycosaminoglycan extracted from shark cartilage. This marine-derived ingredient serves as a structural component of cartilage tissue and is used in joint health product formulations. Sourced from shark cartilage, the material undergoes extraction and purification processes to yield a white or off-white hygroscopic powder. The final product is freely soluble in water and practically insoluble in acetone and ethanol. Business buyers in the supplement manufacturing sector use this ingredient in various dosage forms including capsules, tablets, and powder blends. The ingredient is often combined with other joint support compounds such as glucosamine, MSM, and collagen in finished product formulations.

Shark chondroitin sulfate is sourced exclusively from shark cartilage. The marine origin distinguishes this material from bovine, porcine, or poultry-derived alternatives available on the market. The assay by CPC method on a dry basis ranges from 90.0% to 105.0%, with electrophoretic purity measured at ≤2%. Protein content is limited to ≤6.0%, and nonspecific disaccharides are controlled at ≤10.0%. These parameters define the purity profile of the material for commercial procurement purposes.
Each batch undergoes testing across multiple parameters including identity confirmation via infrared spectroscopy and sodium identification, purity assessment through CPC assay and electrophoretic analysis, and safety evaluation covering heavy metals, residual solvents, and microbial limits. Clarity and color are measured at 420nm with a specification of <0.35. Physical properties including bulk density (≥0.60g/ml), particle size (100% through 80 mesh as standard), and specific rotation (-12.0° to -19.0°) are also verified. Microbial testing covers total plate count, yeast and mold, and specific pathogens including E. coli, Salmonella, S. aureus, and P. aeruginosa.
The production facility operates under ISO and GMP certification, with HACCP-based food safety management systems in place. The product is available with Halal and Kosher certification to meet specific market requirements. The infrared absorption spectrum of the material corresponds to USP Chondroitin Sulfate Sodium Reference Standard, providing alignment with United States Pharmacopeia criteria. Complete documentation packages including Certificate of Analysis (COA), Technical Data Sheet (TDS), and Material Safety Data Sheet (MSDS) are provided with each shipment to support regulatory submissions and quality assurance processes in enterprise customer operations.
Shark chondroitin sulfate is used across industrial applications in the health supplement manufacturing sector. Primary uses include dietary supplements formulated for joint health support. The ingredient is incorporated into multiple delivery formats including hard capsules, tablets, and powder blends. For formulation development, the material is compatible with other active ingredients commonly used in joint health products, including glucosamine, methylsulfonylmethane (MSM), collagen, and hyaluronic acid. Manufacturers may use this ingredient in single-ingredient formulations or as part of complex multi-component blends targeting cartilage maintenance and joint function support.
As a direct manufacturer with over two decades of international export experience, the production facility supports scalable production volumes to accommodate varying order sizes from business buyers. Standard particle size is 100% through 80 mesh, with custom particle sizes available upon request to match specific formulation requirements. The production process maintains batch-to-batch consistency through standardized manufacturing protocols and in-process quality checks. Shipping and export documentation support is provided for global deliveries, including the preparation of all necessary export documentation required for international commercial operations.
Minimum order quantities are determined based on the specific product grade and packaging requirements. Enterprise customers are advised to contact the sales team with their volume requirements to receive specific MOQ details and corresponding pricing information.
Each shipment includes a Certificate of Analysis (COA) detailing actual test results for the specific batch, a Technical Data Sheet (TDS) with product specifications, and a Material Safety Data Sheet (MSDS) with handling and safety information. Additional documentation can be provided upon request to support regulatory compliance requirements in different markets.
Yes, particle size customization is available. The standard specification is 100% through 80 mesh, but alternative particle size distributions can be produced to match specific formulation or processing needs. Other specification adjustments are evaluated on a case-by-case basis depending on technical feasibility and order volume.
Production lead times vary based on order volume and current production scheduling. Standard orders typically ship within established production cycles. International shipping transit times depend on the destination country and chosen shipping method. Specific lead time estimates are provided with formal quotations for commercial procurement.
