Compliance steps

1
Verify the foreign manufacturer holds a current BIS CM/L licence against IS 1879:2010 for malleable cast iron fittings or IS 210:2009 for grey iron castings, as applicable to the specific product being imported. Confirm the licensed scope covers the fitting type, size range, pressure rating, and manufacturing facility on the BIS online register before placing the purchase order.

2
Ensure every fitting bears the ISI mark and the supplier's CM/L number under Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product itself; marking on packaging alone does not satisfy the statutory requirement.

3
Note the phased enforcement schedule for micro and small enterprises: the QCO came into effect for general importers on 01-09-2024, for small enterprises on 01-12-2024, and for micro enterprises on 01-03-2025. Confirm the supplier's enterprise category and applicable enforcement date before filing the bill of entry.

4
Register the consignment on the Steel Import Monitoring System portal no earlier than 60 days before the expected arrival date. Pay the registration fee of ₹500 and retain the automatic registration number, which remains valid for 75 days from issue.

5
Quote both the supplier's BIS CM/L number and the SIMS registration number on the bill of entry. Customs verifies the CM/L in real time against the BIS register and the SIMS registration against the DGFT portal; an absent, expired, or scope-mismatched CM/L triggers consignment detention regardless of SIMS status.

A word of counsel

The most consequential error on this tariff line is importing under a CM/L licence that covers one standard but not the other: a supplier licensed against IS 1879:2010 for malleable cast iron fittings is not automatically licensed against IS 210:2009 for grey iron castings, and vice versa. Where a mixed consignment spans both product types, each product line must be covered by its own licensed scope. Customs detention on a scope mismatch cannot be remedied by retrospective licence amendment — the consignment faces re-export or confiscation.

Frequently asked

Does HSN 7307 19 00 require BIS certification?

Yes. Both IS 1879:2010 (malleable cast iron pipe fittings) and IS 210:2009 (grey iron castings) are mandatory under the ISI Mark Scheme pursuant to the Cast Iron Products (Quality Control) Order, 2023, S.O. 2287(E), with effect from 01 September 2024.

Is SIMS registration required separately from BIS QCO compliance?

Yes. Steel Import Monitoring System registration is administered by the Directorate General of Foreign Trade and is independent of the BIS QCO obligation. The fee is ₹500, the registration is valid for 75 days, and application may be made no earlier than 60 days before the expected arrival date.

Does the phased enforcement schedule affect micro and small enterprise suppliers?

Yes. The QCO applies to general-category manufacturers from 01-09-2024, to small enterprises from 01-12-2024, and to micro enterprises from 01-03-2025. The importer must confirm the supplier's enterprise classification and the applicable enforcement date before the bill of entry is filed.

Does a single CM/L licence cover both malleable cast iron fittings and grey iron castings?

No. IS 1879:2010 and IS 210:2009 are distinct standards requiring separate CM/L licences; a licence issued against one standard does not authorise import of product covered by the other.
