High alumina refractory cement
High alumina refractory cement for industrial furnace linings
HSN 2523 90 20 (high alumina refractory cement) is covered by a Bureau of Indian Standards Quality Control Order. Conformity to IS 15895:2018 is mandatory under the ISI Mark Scheme with effect from 17 February 2003, by virtue of the Cement Quality (Control) Order, 2003. No separate customs-clearance overlay applies beyond the BIS QCO obligation.
- 1Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 15895:2018 for high alumina refractory cement. Verify the CM/L number, product scope, and licensed manufacturing facility on the BIS online register before placing the purchase order.Cement Quality (Control) Order, 2003 · S.O. 191(E) dated 17-02-2003
- 2Confirm that IS 6452 (high alumina cement for structural use) does not apply to the consignment. If the cement is intended for structural applications rather than refractory use, the applicable standard shifts to IS 6452 under the same QCO — a scope distinction customs and BIS both enforce.Cement Quality (Control) Order, 2003 · S.O. 191(E) dated 17-02-2003
- 3Ensure every bag or container bears the ISI mark and the supplier's CM/L number as required under Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product packaging, not only on accompanying documentation.Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018 · Cement Quality (Control) Order, 2003
- 4Quote the supplier's BIS CM/L 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, demurrage, and potential re-export or confiscation.BIS Act, 2016 · Cement Quality (Control) Order, 2003 · Customs Act, 1962
The single most common error on this tariff line is confusing IS 15895:2018 (high alumina refractory cement) with IS 6452 (high alumina cement for structural use): both fall under the same Cement Quality (Control) Order, yet they carry distinct CM/L licences and product scopes. An importer who presents a supplier's CM/L against IS 6452 for a consignment of IS 15895:2018 refractory cement — or vice versa — faces scope-mismatch detention at port regardless of the licence's currency.
