Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 2373 (bulk-type accessories) or IS 779 (domestic-type accessories), as applicable to the specific product variant. Verify the CM/L number, licensed product scope, and manufacturing facility on the BIS online register before placing the purchase order.

2
Ensure each part or accessory bears the ISI mark and the supplier's CM/L number, as prescribed under Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the article itself and not on packaging alone.

Note the staggered enforcement timeline: the QCO obligation is in force from 07-09-2024 for standard enterprises, from 07-12-2024 for small enterprises, and from 07-03-2025 for micro enterprises as defined under clauses (h) and (m) of the MSMED Act, 2006. Confirm the supplier's enterprise classification when assessing compliance obligations.

If the imported parts or accessories are also listed as medical devices under G.S.R. 102(E) issued by the Ministry of Health and Family Welfare, obtain Central Drugs Standard Control Organisation registration separately before import. Quote the CDSCO registration number on the bill of entry.

5
Quote the supplier's BIS CM/L number on the bill of entry, specifying the applicable IS (IS 2373 or IS 779) and product scope. Customs verifies the CM/L against the BIS register in real time; an absent, expired, or scope-mismatched licence triggers consignment detention.

A word of counsel

The single most common error on this tariff line is sourcing under one IS when the product variant requires the other: IS 2373 governs bulk-type water meter accessories and IS 779 governs domestic-type (inferential class, cold potable water) accessories — a CM/L licence scoped to IS 779 does not cover bulk-type accessories, and vice versa. Customs verifies the CM/L's product-scope description against the IS number declared on the bill of entry; a scope mismatch results in detention even where the mark is visibly present on the article.

Frequently asked

Does HSN 9028 90 90 require BIS certification?

Yes. Parts and accessories of water meters classified under this tariff line must conform to IS 2373 (bulk type) or IS 779 (domestic type) under the ISI Mark Scheme. The obligation arises under the Water Meters and Accessories QCO 2023, S.O. 1142(E), with effect from 07 September 2024 for standard enterprises.

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

No. Small enterprises as defined under clause (m) of the MSMED Act, 2006 must comply from 07 December 2024; micro enterprises as defined under clause (h) must comply from 07 March 2025. Standard enterprises are subject to the primary enforcement date of 07 September 2024.

Is CDSCO registration required in addition to BIS QCO compliance?

Only where the goods are also listed as medical devices under G.S.R. 102(E) dated 11-02-2020. That registration is administered by the Central Drugs Standard Control Organisation and is independent of the BIS ISI Mark Scheme obligation.

Does a single CM/L licence cover both bulk-type and domestic-type water meter accessories?

No. IS 2373 and IS 779 are separate Indian Standards; a CM/L licence is scope-specific to the standard, product type, and manufacturing facility. Accessories outside the licensed standard and scope are not covered, and customs will detain a consignment with a mismatched CM/L.
