Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against the applicable Indian Standard — IS 736:1986 for aluminium alloy plates or IS 737:2008 for sheets and strip. Verify the CM/L number, licensed product scope, and manufacturing facility on the BIS online register before placing the purchase order.

2
Confirm that the standard being supplied — IS 736:1986 (plate for general engineering) or IS 737:2008 (sheets and strip for general engineering) — matches the end-use declaration on the commercial invoice. Where the product serves electrical-appliance applications, compliance with IS 5082:1998 may additionally be required; verify the applicable standard against the use case before shipping.

3
Ensure every consignment lot carries the ISI mark and the supplier's CM/L number on the product or on permanently affixed labels traceable to the batch. Marking on packaging alone does not satisfy Scheme-I requirements under the BIS (Conformity Assessment) Regulations, 2018.

4
Quote the supplier's BIS CM/L number and the applicable Indian Standard reference on the bill of entry. Customs verifies the CM/L in real time against the BIS register; an absent, expired, or scope-mismatched licence triggers consignment detention, demurrage, and potential re-export.

5
If the importer is a micro or small enterprise as defined under the Micro, Small and Medium Enterprises Development Act, 2006, note the staggered enforcement dates: micro enterprises become subject from 01 April 2026; small enterprises from 01 January 2026. Non-MSME importers are subject from 01 October 2025.

A word of counsel

The most common error on this tariff line is treating the multiple applicable Indian Standards as interchangeable. IS 736:1986 governs wrought aluminium and aluminium alloy plate, IS 737:2008 governs sheets and strip, and IS 5082:1998 governs the same forms when destined for electrical appliances — the CM/L licence is standard-specific and end-use-specific, so a supplier licensed under IS 737:2008 for general-engineering sheet cannot cover a consignment of plate, nor a consignment destined for electrical-appliance manufacture without a separate IS 5082:1998 licence. Customs port verification matches the declared standard on the bill of entry against the licensed scope on the BIS register; a mismatch on this dimension alone, even with a valid CM/L, results in detention.

Frequently asked

Does HSN 7606 91 20 require BIS certification?

Yes. Electrolytic plates or sheets of unalloyed aluminium under this tariff line must conform to the applicable Indian Standard — IS 736:1986 or IS 737:2008 — and bear the ISI mark under a CM/L licence from the Bureau of Indian Standards, with effect from 01 October 2025 under S.O. 2021(E).

Which Indian Standard applies — IS 736:1986 or IS 737:2008?

IS 736:1986 applies to wrought aluminium and aluminium alloy plate for general engineering; IS 737:2008 applies to sheets and strip for the same purpose. The applicable standard depends on the product form; both fall under this HSN and the QCO.

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

No. Under the Aluminium and Aluminium Alloy Products (Quality Control) Order, 2025, the QCO applies from 01 October 2025 for other importers, from 01 January 2026 for small enterprises, and from 01 April 2026 for micro enterprises as defined in the Micro, Small and Medium Enterprises Development Act, 2006.

Does a CM/L licence for one aluminium product form cover other forms or end-uses under this HSN?

No. The CM/L is standard-specific and scope-specific by product form and end-use. A licence issued under IS 737:2008 for sheets does not cover plate under IS 736:1986, nor electrical-appliance stock under IS 5082:1998.
