In the global trade of high-purity raw materials, meticulous documentation is the cornerstone of regulatory compliance and product safety. For Oat Beta Glucan, both the COA (Certificate of Analysis) and the MSDS (Material Safety Data Sheet) are critical for B2B procurement and formulation.The oat beta glucan COA is the definitive verification of the material's purity, active concentration (e.g., $\geq 70\%$), and the absence of contaminants. This document is essential for validating the quality promised by the supplier (Huatai Bio).Equally important is the oat beta glucan MSDS, which ensures the safe handling, storage, and transport of the powder material, safeguarding warehouse personnel and the product integrity itself.For B2B buyers, verifying these documents is paramount:Safety and Compliance: The MSDS is mandatory for all international shipping and safety protocols, ensuring the powder is handled correctly according to global safety standards.Purity and Specification: The COA verifies the concentration (e.g., 70%), particle size, and molecular weight, confirming the material is fit for its intended use (cosmetic or food grade).Quality Systems: Adherence to the ISO 9001 Quality Management System and ISO 22000 Food Safety Management System guarantees that the complex purification process for the high-purity powder is consistently maintained by the manufacturer.In conclusion, securing certified oat beta glucan requires a complete Technical Dossier, anchored by the COA for quality and the MSDS for safety compliance.
