CRS Mark for Polyphosphoric Acid

Under the Polyphosphoric Acid (Quality Control) Order, 2021 the BIS CRS (Compulsory Registration Scheme) certification for Polyphosphoric Acid guarantees compliance with Indian Standard IS 17439:2020.  Manufacturers wishing to sell or distribute polyphosphoric acid in India must be certified.  Product testing in a BIS-recognized lab, application submission through the BIS site, and compliance verification comprise the procedure.  Foreign producers have to name an Authorized Indian Representative (AIR).  Once approved, the Standard Mark can be used.  Maintaining certification requires routinely audits and quality control assessments.  For both commercial and industrial application, the certification guarantees standardizing, quality, and safety.
