Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 14772:2020 for boxes and enclosures for electrical accessories. Verify the supplier's CM/L number, licensed product scope, and manufacturing facility address on the BIS online register before placing the purchase order.

2
Ensure every junction box bears the ISI mark and the supplier's CM/L licence number under Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. The standard mark must appear on the product itself, not on packaging alone.

3
Confirm the applicable enforcement date for the supplier's enterprise category: large enterprises from 01-07-2024, small enterprises from 01-10-2024, micro enterprises from 01-01-2025. Purchase orders and shipping dates must align with the correct phase.

4
Quote the supplier's BIS CM/L licence 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.

A word of counsel

The most common error on this tariff line is importing from a supplier whose CM/L licence was granted under IS 14772 without confirming whether the licensed scope covers high-voltage junction boxes specifically — IS 14772:2020 governs boxes and enclosures for household and similar electrical installations, and a licence scoped to low-voltage domestic enclosures does not extend to above-1,000-volt apparatus. Customs scrutiny at port is increasing on this distinction; a scope-mismatched CM/L results in detention regardless of whether the ISI mark is physically present on the product.

Frequently asked

Does HSN 8535 90 40 require BIS certification?

Yes. Junction boxes under this tariff line must conform to IS 14772:2020 under the ISI Mark Scheme, enforced from 1 July 2024 for large enterprises under the Electrical Accessories (Quality Control) Order, 2023; the supplier must hold a current BIS CM/L licence.

Do staggered enforcement dates affect when the BIS QCO applies to my import?

Yes. Large enterprises faced the obligation from 01-07-2024, small enterprises from 01-10-2024, and micro enterprises from 01-01-2025. The relevant enterprise classification is that of the manufacturer, and the applicable phase governs whether the CM/L is required on the shipping date.

Does a CM/L licence issued against IS 14772:2020 automatically cover all box and enclosure types?

No. The CM/L is scope-specific by product variant and manufacturing facility; enclosure types or voltage ranges outside the licensed scope are not covered, and a mismatch with the bill of entry triggers detention.

Is a single CM/L licence valid for multiple manufacturing plants of the same supplier?

No. Each CM/L licence is facility-specific; junction boxes manufactured at a plant not listed in the licence are not covered, and shipments from unlicensed facilities are treated as uncertified goods at customs.
