Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 1726:1991 for cast iron manhole covers and frames. Verify the supplier's CM/L number, licensed product scope, load-bearing class, and manufacturing facility address on the BIS online register before placing the purchase order.

2
Ensure every cover and frame bears the ISI mark and the supplier's CM/L number in accordance with Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product casting itself, not on packaging or accompanying documents alone.

3
Register the consignment on the Steel Import Monitoring System portal not earlier than 60 days before the expected arrival date. Fee ₹500, registration valid for 75 days from issue; confirm SIMS registration remains within validity on the date of arrival.

4
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 number against the DGFT portal; either being absent, expired, or scope-mismatched triggers consignment detention.

5
If the enterprise qualifies as a small enterprise, the enforcement date deferred to 01 December 2024 applies; for micro enterprises the deferred date is 01 March 2025. Retain documentary evidence of MSME status to substantiate the applicable enforcement date at the time of import.

A word of counsel

The most common error on this tariff line is importing cast iron drain covers against a CM/L licence that is scoped to a different load-bearing class under IS 1726:1991 than the consignment actually contains. IS 1726:1991 classifies covers by load class (light, medium, heavy, extra heavy), and a CM/L licence covers only the specific class or classes for which the manufacturer is certified; a class mismatch between the licence scope and the physical product triggers detention and re-export even where the ISI mark is physically present on the casting.

Frequently asked

Does HSN 7325 99 92 require BIS certification?

Yes. Conformity to IS 1726:1991 is mandatory under the ISI Mark Scheme from 1 September 2024 (deferred to 1 December 2024 for small enterprises and 1 March 2025 for micro enterprises) under the Cast Iron Products (Quality Control) Order, 2024.

Is Steel Import Monitoring System registration required separately from BIS QCO compliance?

Yes. SIMS registration is administered by the Directorate General of Foreign Trade and is independent of the BIS QCO obligation. Fee ₹500, validity 75 days, application permitted no earlier than 60 days before the expected arrival date.

Do the SIMS carve-outs for re-import or SEZ movements also exempt the BIS QCO?

No. The SIMS exemptions under DGFT policy circular 38/2015-20 do not relax the BIS QCO obligation under IS 1726:1991; the ISI-marked-product requirement continues to apply regardless of the SIMS status of the consignment.

Does a single CM/L licence cover all load-bearing classes of manhole covers from the same manufacturer?

No. A CM/L licence under IS 1726:1991 is scope-specific by load-bearing class and manufacturing facility; covers of a class outside the licensed scope, or from an unlicensed plant, are not covered and attract detention.
