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. Verify the supplier's CM/L number, licensed product scope, size and pressure class, and manufacturing facility address 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 butterfly valve in the consignment 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 ISI mark must appear on the product itself, not on packaging alone.

3
If the consignment also comprises valves intended for fitting to gas cylinders, identify the applicable gas-cylinder valve standard separately. Valves for gas cylinders are governed by IS 3224, IS 3745, IS 7302, IS 8776, IS 8737, IS 15100, IS 12300, or IS 9798 as appropriate — distinct from the IS 13095 butterfly-valve regime.

Quote the supplier's BIS CM/L number on the bill of entry. Customs verifies the CM/L number 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 importing a mixed consignment of butterfly valves alongside other valve types — gate valves, ball valves, check valves — and presenting a single supplier CM/L licence against IS 13095 to cover the entire shipment. IS 13095 covers butterfly valves for general purposes only; all other valve types require their own separately licenced IS standard, and a CM/L scope mismatch on any line item triggers detention of the full consignment. Segregate valve types at the purchase-order stage and confirm that each category is covered by its own CM/L licence before shipment.

Frequently asked

Does HSN 8481 80 49 require BIS certification?

Yes. Butterfly valves for general purposes falling under this tariff line require conformity to IS 13095 under the ISI Mark Scheme, with effect from 1 January 2021, by virtue of the Butterfly Valves (Quality Control) Order, 2020. Import is permitted only from manufacturers holding a current BIS CM/L licence.

Are valves intended for gas cylinders also governed by IS 13095?

No. Valves fitted to gas cylinders are governed by separate BIS standards under Rule 4(1) of the Gas Cylinder Rules, 2016 — including IS 3224, IS 3745, IS 8776, IS 8737, and others depending on cylinder type. IS 13095 applies to butterfly valves for general purposes only.

Does the IS 13095 CM/L licence cover all butterfly valve sizes and pressure classes from a given manufacturer?

No. A CM/L licence is scope-specific by size range, pressure class, and manufacturing facility. Butterfly valves outside the licensed scope, or produced at an unlicensed plant, are not covered and will be detained at customs.

Does a single CM/L licence cover multiple valve types in a mixed consignment?

No. IS 13095 covers butterfly valves for general purposes only. Each distinct valve category in a mixed consignment requires its own CM/L licence against the applicable Indian Standard; presenting an IS 13095 licence for non-butterfly-valve products is a scope mismatch that triggers detention.
