Polyphosphoric Acid is used all over industry but most people don’t really think about the quality side of it until there’s a compliance requirement staring at them. In India this chemical falls under the BIS Compulsory Registration Scheme (CRS) and the relevant standard is IS 17439:2020. If someone wants to manufacture or import it they need to make sure the product meets that Indian Standard and has CRS approval before it goes into the market

What Is Polyphosphoric Acid

Polyphosphoric Acid basically comes from phosphoric acid but with water removed so the molecules sort of chain up and form a thicker more reactive liquid. It’s used for:

  • organic synthesis work
  • dehydrating reactions
  • catalyst functions
  • lubricant additives
  • resin and polymer making

IS 17439:2020 — What the Standard Covers

This standard lays out basic requirements for what can be labelled as polyphosphoric acid in India. It includes points like:

  • minimum purity levels
  • acceptable impurity limits
  • physical appearance
  • testing and sampling procedure
  • packaging and marking

The idea isn’t to make things harder for a manufacturer but to avoid low-grade chemicals entering the supply chain.

Why BIS CRS Registration Is Mandatory

Once BIS puts a product category under CRS the rule becomes pretty non-negotiable. Polyphosphoric Acid is now on that list so you simply cannot sell or import it in India without registration

A few reasons BIS enforces CRS for chemicals:

  • safety concerns (reactive chemicals need control)
  • uniform quality for downstream industries
  • avoiding mislabelling or diluted product
  • traceability back to the manufacturer

Who Needs to Apply

Anyone supplying the chemical in India must get registration. That usually means:

  • Indian manufacturers
  • foreign manufacturers exporting to India
  • importers, acting as the Authorized Indian Representative (AIR)

The licence always belongs to the manufacturer not the importer. Importers only act as communication and documentation support.

Key Requirements Before Applying

From experience, the application feels smooth if the paperwork is ready. Essential items include:

Factory and Company Document

Basic business certificates, manufacturing licences, site details and similar paperwork proving the facility is legitimate

Product Technical Info

Datasheets, chemical composition details and internal QC parameters that show how your polyphosphoric acid aligns with IS 17439:2020

Test Report from BIS Recognized  Lab

This is the big one. BIS accepts only test reports from approved labs. The sample must match the final commercial product otherwise they reject it

AIR Authorisation (for foreign units)

A document that formally allows the Indian representative to file and speak to BIS on behalf of the manufacturer

How the CRS Registration Process Works

The workflow is predictable but small mistakes can slow it down. Here’s the basic sequence:

Step 1: Application Filing

You or your AIR submit the application online, declaring the product category, standard number (IS 17439:2020) and all company details.

Step 2: Sample Testing

You send polyphosphoric acid samples to a BIS-recognized lab. The lab checks purity, chemical structure and other parameters listed in the standard

Step 3: Uploading the Test Report

When the lab sends the report it must be uploaded exactly as BIS expects. Even minor mismatches in product name or grade can cause resubmission

Step 4: BIS Review

Officials check all documents, test reports and manufacturing info. If something looks unclear they may ask for clarification

Step 5: Grant of Registration

If everything is in order BIS issues the CRS registration number

Step 6: Standard Marking

Every package or container must carry the BIS Standard Mark and your CRS number. Missing markings can create issues during inspection or customs checks

Common Problems Applicants Face

These issues come up more often than people expect:

  • incorrect reference to the standard
  • mismatch between sample label and document details
  • incomplete testing (missing parameters)
  • AIR documents not notarised
  • technical datasheets too vague

Fixing these usually isn’t complex but it costs time. Better to correct them before submission.

Risks of Ignoring CRS Requirements

Skipping BIS registration might seem convenient, but the consequences are serious:

  • customs seizure of shipments
  • fines and legal notices
  • goods stuck in warehouses for months
  • loss of business credibility

A compliant manufacturer or importer avoids all this trouble and achieves smoother operations.

Practical Tips for a Smooth Approval

Here are a few quick pointers that save effort:

  • send fresh product samples to the lab (old samples may degrade)
  • cross-verify test parameters before uploading
  • make sure packaging reflects marking rules
  • keep every communication copy for later audits
  • avoid last-minute filings — BIS queues get long

A little organisation goes a long way in compliance work.

Conclusion

Polyphosphoric Acid is a high significance industrial chemical and BIS has required its registration as mandatory to provide safe and reliable supply. Manufacturers and importers are bound to comply with stringent quality standards in the manufacture and import of the product to Indian users under the IS 17439: 2020.

Businesses are able to have an easier clearance once the registration of CRS has been issued and this increases customer confidence and full adherence to the national policies. It will seem to create additional paperwork in the initial days but in the long term it will protect the industry and the final consumers. Contact Agile Regulatory for a hassle-free process.
