HSN 7411 21 00 (copper tubes and pipes of copper-zinc base alloys, brass) is covered by a Bureau of Indian Standards Quality Control Order under the Copper Products (Quality Control) Order, 2023. Conformity to IS 1545:1994, IS 2501:1995, IS 14810:2000, and IS 10773:1995 is mandatory under the ISI Mark Scheme, with effect from 26 April 2024 for enterprises other than small and micro enterprises.

Compliance steps

1
Verify the foreign manufacturer holds a current BIS CM/L licence against the applicable Indian Standard for the specific tube type: 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). Confirm the licensed scope, size range, and manufacturing facility on the BIS online register before the purchase order.

2
Ensure every tube 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 or in a permanently traceable format, not on packaging alone.

3
Register the consignment on the Non-Ferrous Metals Import Monitoring System portal before arrival, no earlier than 60 days before the expected date of arrival. Fee ₹500; the automatic registration number is valid for 75 days. The minimum advance-registration window of 5 days has been abolished.

4
Quote both the supplier's BIS CM/L number and the NFMIMS automatic registration number on the bill of entry. Customs verifies the CM/L against the BIS register and the NFMIMS registration against the DGFT portal; either being absent, expired, or scope-mismatched triggers consignment detention.

For wrought copper tubes for refrigeration and air conditioning under IS 10773:1995, confirm compliance with the second proviso in paragraph 2 of the Copper Products (Quality Control) Order, 2024, as amended by the Copper Products (Quality Control) Amendment Order, 2025. Small enterprise enforcement began 19-01-2025; micro enterprise enforcement begins 19-04-2025.

A word of counsel

The single most common error on this tariff line is treating the four applicable Indian Standards as interchangeable and sourcing from a CM/L-licensed manufacturer without verifying that the licence covers the precise tube application — condenser, general engineering, plumbing, or refrigeration. A CM/L issued against IS 2501:1995 for general engineering tubes does not authorise import of refrigeration tubes requiring IS 10773:1995, and customs will detain the consignment on a scope mismatch even where the supplier is otherwise BIS-licensed. Verify the IS number, tube application, and facility address in the CM/L scope column on the BIS register against the purchase specification before placing the order.

Frequently asked

Does HSN 7411 21 00 require BIS certification?

Yes. Brass copper tubes and pipes under this tariff line must conform to the relevant Indian Standard — IS 1545:1994, IS 2501:1995, IS 14810:2000, or IS 10773:1995 — and bear the ISI mark under a BIS CM/L licence, with effect from 26 April 2024 under the Copper Products (Quality Control) Order, 2023.

Is NFMIMS registration required separately from BIS QCO compliance?

Yes. Non-Ferrous Metals Import Monitoring System registration is administered by the Directorate General of Foreign Trade and is independent of the BIS QCO. Fee ₹500, validity 75 days, apply no earlier than 60 days before the expected arrival date.

Do the staggered enforcement dates affect micro and small enterprises?

Yes. The BIS QCO obligation applied from 19-10-2024 for enterprises other than small and micro; from 19-01-2025 for small enterprises; and from 19-04-2025 for micro enterprises. An enterprise must assess its MSMED Act classification to determine which date governs its compliance obligation.

Does a single CM/L licence cover all four tube applications from one manufacturer?

No. Each Indian Standard (IS 1545:1994, IS 2501:1995, IS 14810:2000, IS 10773:1995) requires a separate scope entry in the CM/L; tubes of an application not listed in the licence, or from an unlicensed facility, are not covered and will be detained at port.
