Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against the applicable IS: IS 1545:1994 (condenser and heat-exchanger tubes), IS 2501:1995 (general engineering tubes), IS 14810:2000 (plumbing tubes), or IS 10773:1995 (refrigeration and air-conditioning tubes). Verify the CM/L number, licensed product scope, and facility address on the BIS online register before placing the purchase order.

2
Confirm which IS standard governs the specific tube end-use: IS 1545:1994 for condensers and heat exchangers, IS 2501:1995 for general engineering, IS 14810:2000 for plumbing, and IS 10773:1995 for refrigeration and air conditioning. A CM/L licence against the wrong IS does not satisfy the QCO obligation for a different tube application.

3
Ensure every tube or pipe 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 itself; packaging-only marking does not satisfy the statutory requirement.

4
For wrought copper tubes used in refrigeration and air conditioning (IS 10773:1995), verify the applicable enforcement date for the supplier's enterprise category: 19 October 2024 for enterprises other than small and micro, 19 January 2025 for small enterprises, and 19 April 2025 for micro enterprises. Also check compliance with the second proviso of paragraph 2 of the Copper Products (Quality Control) Amendment Order, 2025.

5
Check whether the consignment falls within the 10,000 MT Tariff Rate Quota for copper products under the India-Nepal Treaty allocation. If so, obtain the requisite TRQ allocation reference from the Directorate General of Foreign Trade under paragraph 2.92 of the Handbook of Procedures, 2023 and quote it on the bill of entry.

A word of counsel

The most common error on this tariff line is presenting a single CM/L licence without verifying that it matches the declared end-use application of the tubes. IS 1545:1994, IS 2501:1995, IS 14810:2000, and IS 10773:1995 each govern a distinct use-category; a CM/L against IS 2501 (general engineering) does not cover tubes invoiced as refrigeration-grade product falling under IS 10773, and customs has authority to detain the entire consignment on that scope mismatch alone. Confirm end-use-specific standard and licence scope in the supplier's CM/L certificate before the purchase order is placed.

Frequently asked

Does HSN 7411 22 00 require BIS certification?

Yes. Copper tubes and pipes under this tariff line must conform to the applicable Indian Standard under the ISI Mark Scheme with effect from 26 April 2024; import is permitted only from manufacturers holding a current BIS CM/L licence covering the relevant end-use standard and facility.

Which Indian Standard applies to my specific tube end-use?

IS 1545:1994 governs condenser and heat-exchanger tubes; IS 2501:1995 governs general engineering tubes; IS 14810:2000 governs plumbing tubes; IS 10773:1995 governs refrigeration and air-conditioning tubes. The CM/L licence must correspond to the declared end-use.

Do the phased enforcement dates for micro and small enterprises affect import obligations?

Yes, for IS 10773:1995 (refrigeration and air-conditioning tubes). The QCO obligation applies from 19 October 2024 for other enterprises, 19 January 2025 for small enterprises, and 19 April 2025 for micro enterprises per S.O. 884(E) dated 19-02-2025.

Does a single CM/L licence cover all four end-use categories?

No. A CM/L licence is standard-specific and facility-specific; a licence against one IS does not authorise import of tubes governed by a different IS, and customs will detain consignments where the declared end-use falls outside the licensed scope.
