Of which the maximum cross-sectional dimension exceeds 7 mm

Aluminium wire of cross-section exceeding 7 mm

BIS QCO APPLICABLE · ISI MARK SCHEME · IS 739

HSN 7605 21 00 (aluminium wire of cross-sectional dimension exceeding 7 mm) is covered by a Bureau of Indian Standards Quality Control Order. Conformity to IS 739:1992 (general engineering purposes) and IS 2067:1975 (electrical purposes) is mandatory under the ISI Mark Scheme with effect from 1 October 2025, under the Aluminium and Aluminium Alloy Products (Quality Control) Order, 2025. No separate customs-clearance overlay applies beyond the BIS obligation.

Compliance steps

1
Determine whether the aluminium wire is intended for general engineering purposes (governed by IS 739:1992) or for electrical purposes (governed by IS 2067:1975). Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against the applicable standard.

2
Verify the supplier's BIS CM/L number, licensed product scope, and licensed manufacturing facility address on the BIS online register before placing the purchase order. The licence must expressly cover the wire diameter range and alloy designation of the consignment.

3
Ensure every coil or reel of wire bears the ISI mark and the supplier's CM/L number, applied under Scheme-I of Schedule-II of the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product or its attached label, not only on outer packaging.

4
Quote the supplier's BIS CM/L number 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 or confiscation.

5
If the importer qualifies as a micro enterprise under the Micro, Small and Medium Enterprises Development Act, 2006, note that the effective QCO date is 01 April 2026; for small enterprises the effective date is 01 January 2026. Document MSMED registration to support any transitional-period claim at the port of entry.

A word of counsel

The single most common error on this tariff line is applying a single CM/L licence to both general-engineering and electrical-purpose wire, when each end-use calls for a distinct Indian Standard — IS 739:1992 for wrought aluminium alloy wire for general engineering and IS 2067:1975 for wrought aluminium wire for electrical purposes. A licence granted against one standard does not cover shipments intended for the other end-use; customs examining the end-use declaration against the CM/L scope will detain a consignment where there is a mismatch, even where the physical product is identical in cross-section.

Frequently asked

Does HSN 7605 21 00 require BIS certification?

Yes. Aluminium wire of cross-sectional dimension exceeding 7 mm must conform to IS 739:1992 or IS 2067:1975 under the ISI Mark Scheme, with the BIS obligation in force from 1 October 2025 under the Aluminium and Aluminium Alloy Products (Quality Control) Order, 2025.

Which Indian Standard applies, IS 739:1992 or IS 2067:1975?

IS 739:1992 applies to wrought aluminium and aluminium alloy wire for general engineering purposes; IS 2067:1975 applies to wrought aluminium wire for electrical purposes. The supplier's CM/L licence must be obtained against the standard matching the wire's declared end-use.

Do micro and small enterprises have different QCO effective dates?

Yes. For micro enterprises as defined under the Micro, Small and Medium Enterprises Development Act, 2006, the effective date is 1 April 2026; for small enterprises it is 1 January 2026. The general effective date for all other importers is 1 October 2025.

Does a single CM/L licence cover all wire diameters and alloy grades from one manufacturer?

No. A CM/L licence is scope-specific by standard, alloy designation, and wire diameter range; wire outside the licensed scope or from an unlicensed manufacturing facility is not covered and attracts detention at the port of entry.
