Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 1489 (Part 1) for fly-ash-based Portland pozzolana cement or IS 1489 (Part 2) for calcined-clay-based variety. Verify the CM/L number, part-specific scope, and licensed facility on the BIS online register before placing the purchase order.

2
Confirm that the CM/L licence explicitly identifies the correct Part — Part 1 (fly-ash based) or Part 2 (calcined clay based) — matching the consignment. A CM/L for one part does not cover the other; scope mismatch triggers detention at port.

3
Ensure every bag or bulk-delivery document bears the ISI mark, the supplier's CM/L number, and the applicable IS 1489 part designation traceable to the licensed manufacturing facility. Marking must appear on the product packaging itself, not only on accompanying documentation.

4
Quote the supplier's BIS CM/L number and the applicable IS 1489 part on the bill of entry. Customs verifies the CM/L in real time against the BIS register; an absent, expired, or part-mismatched licence triggers consignment detention, demurrage, and potential re-export.

A word of counsel

The most frequent error on this tariff line is treating the two parts of IS 1489 as interchangeable under a single CM/L licence: a supplier licensed for IS 1489 (Part 1) fly-ash-based cement cannot lawfully supply IS 1489 (Part 2) calcined-clay-based cement, and customs will detain the consignment on a part-number mismatch even where the broader IS number on the CM/L appears correct. Verify the Part designation on the CM/L certificate — not merely the IS number — against the pozzolanic material type declared on the test report and the shipping documentation before the purchase order is placed.

Frequently asked

Does HSN 2523 29 30 require BIS certification?

Yes. Portland pozzolana cement under this tariff line requires conformity to IS 1489 (Part 1) or IS 1489 (Part 2) under the ISI Mark Scheme, mandatory with effect from 17 February 2003 under the Cement Quality Control Order, 2003; import is permitted only from manufacturers holding a current BIS CM/L licence covering the relevant Part.

What is the difference between IS 1489 Part 1 and Part 2 for import purposes?

IS 1489 (Part 1) governs fly-ash-based Portland pozzolana cement; IS 1489 (Part 2) governs calcined-clay-based Portland pozzolana cement. Each Part requires a separate CM/L licence, and the bill of entry must specify the correct Part matching the consignment.

Does the Cement Quality Control Order cover other cement types under Chapter 25?

Yes. The Cement Quality Control Order, 2003 under S.O. 191(E) also covers sulphate-resisting Portland cement (IS 12330), low-heat Portland cement (IS 12600), masonry cement (IS 3466), rapid-hardening Portland cement (IS 8041), and hydrophobic Portland cement (IS 8043), each under a separate IS and CM/L scope.

Does a single CM/L licence cover both fly-ash-based and calcined-clay-based Portland pozzolana cement?

No. The CM/L is Part-specific; a licence issued against IS 1489 (Part 1) does not authorise supply of IS 1489 (Part 2) product, and a consignment of the non-licensed Part will be detained at port regardless of the IS number appearing on the licence.
