Compliance steps

1
Identify the precise cement type being imported and confirm the governing Indian Standard: IS 12330 (sulphate resisting Portland cement), IS 12600 (low heat Portland cement), IS 1489 Part 1 (Portland Pozzolana cement, fly-ash based), IS 1489 Part 2 (Portland Pozzolana cement, calcined clay based), IS 3466 (masonry cement), IS 8041 (rapid hardening Portland cement), IS 8043 (hydrophobic Portland cement), IS 15895:2018 (high alumina refractory cement), or IS 6452 (high alumina cement for structural use).

2
Source only from a manufacturer holding a current BIS CM/L licence against the specific IS number governing the cement type. Verify the supplier's CM/L number, licensed product scope, and manufacturing facility on the BIS online register before placing the purchase order.

3
Ensure every bag or bulk consignment bears the ISI mark and the supplier's CM/L number traceable to the licensed manufacturing facility and the specific cement type. Marking must appear on the product packaging in the form prescribed under the BIS (Conformity Assessment) Regulations, 2018.

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

A word of counsel

The single most common error on this tariff line is treating the CM/L licence of a related cement type as interchangeable across specifications — for example, presenting an IS 6452 (high alumina cement for structural use) licence for a consignment of IS 15895:2018 (high alumina refractory cement). Each Indian Standard under the Cement Quality (Control) Order, 2003 is a distinct licensing scope; a CM/L issued against one IS does not cover another, and customs detention follows automatically when the declared IS does not match the scope on the BIS register.

Frequently asked

Does HSN 2523 90 10 require BIS certification?

Yes. All hydraulic cements under this tariff line require ISI Mark Scheme certification under the Cement Quality (Control) Order, 2003 (S.O. 191(E) dated 17-02-2003); import is permitted only from manufacturers holding a current CM/L licence against the specific governing Indian Standard.

Which Indian Standard applies to my cement type?

The governing standard depends on the cement type: IS 12330 for sulphate resisting Portland, IS 12600 for low heat Portland, IS 1489 Part 1 or Part 2 for Portland Pozzolana, IS 3466 for masonry, IS 8041 for rapid hardening Portland, IS 8043 for hydrophobic Portland, IS 15895:2018 for high alumina refractory, and IS 6452 for high alumina cement for structural use.

Does a single CM/L licence cover multiple cement types or IS standards?

No. Each CM/L licence is specific to the cement type and the Indian Standard it is issued against; a licence for one standard does not authorise import of a cement type governed by a different IS number.

Is the CM/L licence facility-specific?

Yes. The CM/L is tied to the licensed manufacturing facility; cement produced at a different plant, even by the same company, is not covered by a licence issued for another facility.
