Other hydraulic cements (supersulphated, oil well, refractory, composite)
HSN 2523 90 90 (other hydraulic cements) 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, by virtue of the Cement Quality Control Order, 2003 [S.O. 191(E)]. This tariff line spans multiple cement types, each mapped to a distinct IS standard; the correct standard is determined by the specific cement type being imported.
- 1Identify the precise cement type being imported and match it to 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 16415:2015 (composite cement), IS 6909 (supersulphated cement), IS 8229 (oil well cement), IS 15895:2018 (high alumina refractory cement), or IS 6452 (high alumina cement for structural use).Cement Quality Control Order, 2003 · S.O. 191(E) dated 17-02-2003
- 2Verify the foreign manufacturer's BIS CM/L licence on the BIS online register before placing the purchase order. The licence must be current, must specify the correct IS standard for the cement type, and must cover the manufacturing facility from which the consignment will be despatched.Cement Quality Control Order, 2003 · S.O. 191(E) dated 17-02-2003 · ISI Mark Scheme under Scheme-I of the BIS (Conformity Assessment) Regulations, 2018
- 3Ensure every bag or bulk consignment bears the ISI mark and the supplier's CM/L number traceable to the licensed facility and the specific IS standard. Marking must appear on the packaging in the format prescribed under the BIS (Conformity Assessment) Regulations, 2018.BIS (Conformity Assessment) Regulations, 2018 · Scheme-I marking format · Cement Quality Control Order, 2003
- 4Quote the supplier's BIS CM/L number and the applicable IS standard on the bill of entry. Customs verifies the CM/L in real time against the BIS register; a CM/L that is absent, expired, issued against a different IS standard, or not covering the consigning facility triggers consignment detention.Cement Quality Control Order, 2003 · S.O. 191(E) dated 17-02-2003 · BIS Act, 2016 · Customs Act, 1962
The single most common error on this tariff line is sourcing under a CM/L licence that is valid in principle but mapped to the wrong IS standard for the cement type actually shipped — for example, clearing a consignment of high alumina refractory cement under a CM/L issued against IS 12330 (sulphate-resisting Portland cement). Because each IS standard is a distinct licence scope, customs detention follows not from the absence of a CM/L but from a standard mismatch between the licence, the ISI mark on the bags, and the product actually in the consignment.
