Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 13095 for butterfly valves for general purposes. Verify the supplier's CM/L number, licensed product scope, size range, and manufacturing facility on the BIS online register before placing the purchase order.
Butterfly Valves (Quality Control) Order, 2020 · S.O. 1920(E) dated 17-06-2020
2
Ensure every valve bears the ISI mark and the supplier's CM/L number under Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. The marking must appear on the product itself, not on packaging alone.

3
If the consignment comprises valves fitted to gas cylinders, confirm separately whether the applicable gas-cylinder-specific BIS standard applies — IS 3224, IS 3745, IS 7302, IS 8776, IS 8737, IS 15100, IS 12300, or IS 9798 — under Rule 4(1) of the Gas Cylinder Rules, 2016. The IS 13095 QCO and the gas-cylinder-valve regime operate independently.

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 product-scope-mismatched licence triggers consignment detention, demurrage, and potential re-export or confiscation.

A word of counsel

The single most common error on this tariff line is assuming that any valve compliant with a gas-cylinder-specific BIS standard — IS 3224, IS 9798, or similar — automatically satisfies the IS 13095 QCO for butterfly valves for general purposes. These are parallel and independent obligations: a valve destined for a gas cylinder must meet the gas-cylinder regime under the Gas Cylinder Rules, 2016, while a butterfly valve for general purposes must bear a CM/L licence against IS 13095 regardless of any gas-cylinder certification the manufacturer may hold. Importing butterfly valves without a current IS 13095 CM/L licence exposes the consignment to detention at port irrespective of other BIS credentials.

Frequently asked

Does HSN 8481 80 90 require BIS certification?

Yes. Butterfly valves for general purposes falling under this tariff line require Bureau of Indian Standards certification under the ISI Mark Scheme against IS 13095, with effect from 1 January 2021, under the Butterfly Valves (Quality Control) Order, 2020.

Do gas-cylinder valve standards such as IS 3224 or IS 9798 satisfy the IS 13095 QCO requirement?

No. The gas-cylinder valve standards mandated under Rule 4(1) of the Gas Cylinder Rules, 2016 are a separate regime; IS 13095 covers butterfly valves for general purposes, and a CM/L licence against IS 13095 is required independently of any gas-cylinder-specific certification.

From which date is the Butterfly Valves (Quality Control) Order, 2020 enforceable?

The order notified by S.O. 1920(E) dated 17 June 2020 took effect from 1 January 2021; consignments imported on or after that date require a valid CM/L licence against IS 13095.

Does a single CM/L licence cover all butterfly valve sizes and pressure classes from the same manufacturer?

No. A CM/L licence is scope-specific; it covers the valve sizes, pressure ratings, and manufacturing facility stated in the licence. Valves outside the licensed scope or from an unlicensed plant are not covered.
