Pursuant to this order, BIS has mandated the compulsory registration of polyphosphoric acid under the CRS scheme and the obligatory use of the Standard Mark, following the standards set by IS 17439:2020.

Issued by the Ministry of Chemicals and Petrochemicals, this order was officially published on December 24, 2021, in the official gazette. It is set to become effective on the one hundred and eighty-first day (181st Day) from its publication in the official gazette.

  • Choose a testing organization recognized by BIS and consider a compliance partner's help until you're ready to handle things in India.
  • Make sure the testing lab has a valid license, and it's not in the middle of an audit.
  • Before sending samples, plan out the whole shipment process to the testing lab's doorstep.
  • Sign all documents with the manufacturer, brand owner, and Indian Representative. Also, get these documents notarized and stamped.
  • Be accurate when filling out the product details in the Construction Data form (CDF) and provide brief, precise information about the product components in the Critical Component List (CCL).
  • Remember, a test report is valid for 3 months. If you can't send it to BIS before it expires, you'll need to test a new sample.
  • Get all your documents ready before testing the sample.BIS typically takes around 15 days to approve the registration.
