BIS QCO APPLICABLE · ISI MARK SCHEME · IS 12330

HSN 2523 29 90 covers other hydraulic cements — including composite, supersulphated, masonry, hydrophobic, oil well, rapid-hardening, and Portland pozzolana variants — and is covered by a Bureau of Indian Standards Quality Control Order. Conformity to the applicable Indian Standard is mandatory under the ISI Mark Scheme with effect from 17 February 2003, pursuant to the Cement Quality Control Order, 2003. No separate customs-clearance overlay applies beyond the BIS QCO obligation.

Compliance steps

1
Identify the precise cement type in the consignment and map it to the controlling Indian Standard: IS 12330 (sulphate-resisting Portland cement), IS 12600 (low-heat Portland cement), IS 1489 (Part 1) (Portland pozzolana — fly-ash based), IS 1489 (Part 2) (Portland pozzolana — calcined clay based), IS 3466 (masonry cement), IS 8041 (rapid-hardening Portland cement), IS 8043 (hydrophobic Portland cement), IS 16415:2015 (composite cement), IS 6909 (supersulphated cement), or IS 8229 (oil well cement).

2
Verify the foreign manufacturer's BIS CM/L licence number on the BIS online register before placing the purchase order. The licence must be current, cover the specific cement type and standard identified above, and name the manufacturing facility from which the consignment will be shipped.

3
Ensure each bag or bulk consignment bears the ISI mark, the supplier's CM/L number, and the applicable IS number visibly and durably. Marking must appear on the product or immediate packaging — not only on outer shipping containers.

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

A word of counsel

The single most common error on this tariff line is presenting a CM/L licence against one cement type (for example, IS 12330 for sulphate-resisting Portland cement) while the consignment contains a different variant (for example, IS 16415:2015 composite cement). Each of the ten Indian Standards mapped to this HSN is a distinct licensed scope; a licence issued for one standard does not extend to any other, and customs detains the entire consignment on a standard-code mismatch. Confirm the precise cement type in the supplier's technical data sheet, match it to the correct IS number, and verify the CM/L covers that exact standard before the purchase order is placed.

Frequently asked

Does HSN 2523 29 90 require BIS certification?

Yes. All cement types under this tariff line require a BIS CM/L licence under the ISI Mark Scheme, with effect from 17 February 2003 under the Cement Quality Control Order, 2003. The applicable IS number depends on the cement type being imported.

Which Indian Standard applies to my specific cement type?

The standard is type-specific: IS 12330 (sulphate-resisting), IS 12600 (low-heat), IS 1489 Part 1 or Part 2 (Portland pozzolana), IS 3466 (masonry), IS 8041 (rapid-hardening), IS 8043 (hydrophobic), IS 16415:2015 (composite), IS 6909 (supersulphated), or IS 8229 (oil well). One CM/L does not cover all types.

Is there any additional customs-clearance overlay such as SIMS or EPR for cement imports under this HSN?

No additional customs-clearance overlay applies to this tariff line. The sole regulatory requirement is BIS QCO compliance under the Cement Quality Control Order, 2003.

Does a single CM/L licence cover all cement variants and manufacturing facilities of the same supplier?

No. A CM/L licence is specific to the Indian Standard (cement type), the licensed product specification, and the named manufacturing facility; a different cement type or a different plant requires a separate CM/L licence.
