Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 6392:2020 for steel pipe flanges. Verify the supplier's CM/L number, licensed product scope, size and pressure class, and manufacturing facility address on the BIS online register before placing the purchase order.
IS 6392:2020 applicable on steel pipe flanges with effect from 27-03-2024 · ISI Mark Scheme under Scheme-I of the BIS (Conformity Assessment) Regulations, 2018
2
Ensure every flange bears the ISI mark, the supplier's CM/L number, and a batch identifier traceable to the licensed manufacturing facility. The marking must appear on the product itself, not on packaging alone.
BIS (Conformity Assessment) Regulations, 2018 · Scheme-I marking requirements
3
Register the consignment on the Steel Import Monitoring System portal no earlier than 60 days before the expected arrival date. The registration fee is ₹500, and the automatic registration number remains valid for 75 days from issue.

4
Quote both the supplier's BIS CM/L number and the SIMS automatic 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.
Policy Condition 2 of Chapter 73 · BIS Act, 2016 · Customs Act, 1962
5
If the consignment is a re-import for packaging purposes only, or involves a DTA-to-SEZ-to-DTA movement, document the applicable SIMS exemption basis in writing. The BIS QCO obligation under IS 6392:2020 is not waived by either SIMS carve-out — the ISI-marked product requirement continues to apply.

A word of counsel

The most frequent compliance failure on this tariff line is treating the SIMS registration as the principal obligation while overlooking scope specificity within the BIS CM/L licence itself. A CM/L licence is facility-specific and covers only the size range, pressure class, and flange type explicitly listed in the licence schedule; flanges outside those parameters — even from the same manufacturer — are not covered, and customs detains the consignment on a scope mismatch regardless of whether the SIMS registration is valid.

Frequently asked

Does HSN 7307 91 10 require BIS certification?

Yes. Conformity to IS 6392:2020 is mandatory under the ISI Mark Scheme from 27 March 2024; import is permitted only from manufacturers holding a current BIS CM/L licence covering the relevant flange size, pressure class, and manufacturing facility.

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 registration fee is ₹500, the automatic registration number is valid for 75 days, and application may be made no earlier than 60 days before the expected arrival date.

Do the SIMS carve-outs for re-imports and SEZ movements also exempt the BIS QCO?

No. The SIMS carve-outs under DGFT Policy Circular 38/2015-20 affect only the SIMS registration requirement; the BIS QCO obligation under IS 6392:2020 and the requirement for ISI-marked flanges from a CM/L-licensed manufacturer are not affected.

Does a single CM/L licence cover all flange sizes and pressure classes from the same manufacturer?

No. A CM/L licence is scope-specific by size range, pressure class, flange type, and manufacturing facility; flanges outside the licensed parameters, or produced at an unlicensed plant, are not covered and will be detained at customs.
