Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 2692:1989 for copper-alloy tube-well strainers. Verify the supplier's CM/L number, licensed product scope, and manufacturing facility on the BIS online register before placing the purchase order.

2
Ensure every tube-well strainer 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 and not solely on the outer packaging.

3
Confirm whether the supplying enterprise qualifies as a small or micro enterprise under clauses (h) and (m) of the MSMED Act, 2006. Small enterprises were granted a deferred enforcement date of 07-12-2024; micro enterprises a further deferral to 07-03-2025.

4
Check whether the consignment falls within the DGFT tariff-rate quota for copper products under Chapter 74, and if so, obtain the applicable TRQ allocation before shipment. Quote the BIS CM/L number and, where required, the TRQ allocation reference on the bill of entry.

A word of counsel

The single most common error on this tariff line is overlooking the phased enforcement calendar: importers sourcing from small or micro enterprises — whether foreign or domestic-equivalent — assume the general 07 September 2024 enforcement date applies universally. It does not. Consignments from suppliers that qualify as small enterprises under the MSMED Act, 2006 were outside mandatory ISI Mark scope until 07 December 2024, and micro enterprises until 07 March 2025; demanding a CM/L from a supplier in a deferred category before its effective date, or accepting unmarked goods after it, both produce a mismatch that triggers detention.

Frequently asked

Does HSN 7412 20 11 require BIS certification?

Yes. Tube-well strainers of copper-alloy construction must conform to IS 2692:1989 under the ISI Mark Scheme, mandatory from 07 September 2024 for general enterprises, under the Water Meters and Accessories Quality Control Order, 2023 notified by S.O. 1142(E).

Do small and micro enterprises face the same enforcement date as general enterprises?

No. Small enterprises as defined under the MSMED Act, 2006 were subject to enforcement from 07 December 2024; micro enterprises from 07 March 2025. After those dates, the ISI Mark obligation applies uniformly regardless of enterprise size.

Does the DGFT tariff-rate quota for Chapter 74 copper products affect BIS QCO compliance?

The TRQ framework administered by the Directorate General of Foreign Trade under DGFT Public Notice 17/2023 is an independent customs-clearance overlay; it does not waive or modify the IS 2692:1989 ISI Mark obligation, which remains a separate statutory requirement.

Does a single CM/L licence cover all copper-alloy fitting types under IS 2692:1989?

No. The CM/L is scope-specific by product type, pressure rating, and manufacturing facility; tube-well strainers outside the licensed specification, or produced at an unlicensed plant, are not covered and are liable to detention at the port of import.
