BIS QCO APPLICABLE · ISI MARK SCHEME · IS 13095

HSN 8481 80 50 (expansion valves and solenoid valves for refrigerating and air conditioning appliances and machinery) is covered by a Bureau of Indian Standards Quality Control Order. Conformity to IS 13095 is mandatory under the ISI Mark Scheme with effect from 01 January 2021, by virtue of the Butterfly Valves (Quality Control) Order, 2020. Bureau of Indian Standards is the sole Partner Government Agency for this tariff line.

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, 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 valve bears the ISI mark and the supplier's CM/L number as required under Scheme-I of the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product itself and not on packaging alone.

3
Where the valves are intended for fitment to gas cylinders, verify additionally that the applicable BIS standard for the cylinder type is satisfied — IS 3224 (industrial/CNG), IS 12300 (small refrigerant cylinder), or the relevant standard approved by the Chief Controller. The IS 13095 QCO obligation is independent of these cylinder-valve requirements.

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 product-scope-mismatched CM/L 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 IS 13095 governs only generic butterfly valves and does not apply to expansion or solenoid valves classified here for refrigeration and air conditioning use. The QCO attaches at the tariff-line level — the ISI Mark Scheme obligation under S.O. 1920(E) applies to the goods as classified under HSN 8481 80 50 regardless of the downstream application — and importers who present valves without a valid CM/L against IS 13095 face detention even where the goods are demonstrably destined for HVAC end-use and not general pipework.

Frequently asked

Does HSN 8481 80 50 require BIS certification?

Yes. Conformity to IS 13095 is mandatory under the ISI Mark Scheme with effect from 01 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 covering the relevant valve scope and facility.

Does the gas cylinder valve regime under the Gas Cylinder Rules, 2016 replace the IS 13095 QCO obligation?

No. The Gas Cylinder Rules, 2016 impose additional BIS standard requirements for valves fitted to specific cylinder types; these operate alongside the IS 13095 QCO obligation and do not substitute for it.

Why does IS 13095, titled for butterfly valves, apply to expansion and solenoid valves under HSN 8481 80 50?

The Butterfly Valves (Quality Control) Order, 2020 covers the tariff line HSN 8481 80 50 as a whole; the BIS QCO obligation attaches at the classified tariff-line level, and all goods cleared under this HSN must meet IS 13095 requirements.

Does a single CM/L licence cover all valve variants and manufacturing facilities of the same supplier?

No. The CM/L is scope-specific by valve type, size range, and manufacturing facility; variants outside the licensed scope, or produced at an unlicensed plant, are not covered and will be detained at customs.
