CRS Mark for Ortho Phosphoric Acid

The BIS CRS (Compulsory Registration Scheme) Mark for Ortho Phosphoric Acid (H₃PO₄) guarantees conformity with IS 798:2020, which establishes quality and safety criteria for technical and food-grade phosphorous acid.  Manufacturers have to apply via the Manak Online Portal (www.manakonline.in) and have products tested in a laboratory certified by BIS.  Production procedures are checked in a plant.  Compliance results in the ISI mark, therefore guaranteeing regulatory approval.  In India, industrial, agricultural, and food uses depend on the certification.  Maintaining certification and quality assurance calls both renewal and regular testing.
