Taps, cocks and similar appliances of non-ferrous metal

Non-ferrous metal taps, cocks and similar appliances (valves, regulators)

BIS QCO APPLICABLE · ISI MARK SCHEME · IS 3224

HSN 8481 80 20 (taps, cocks and similar appliances of non-ferrous metal) is covered by a Bureau of Indian Standards Quality Control Order. Conformity to applicable Indian Standards under the ISI Mark Scheme is mandatory, with the Butterfly Valves (Quality Control) Order, 2020 establishing the IS 13095 obligation with effect from 01 January 2021, and Gas Cylinder Rules, 2016 mandating separate IS-specific compliance for valves fitted to gas cylinders. No additional customs-clearance overlay beyond the BIS obligation applies to this tariff line.

Compliance steps

1
Identify which Indian Standard governs the specific valve or fitting being imported: IS 13095 for butterfly valves; IS 3224 for industrial gas and CNG on-board cylinder valves; IS 3745 for medical gas cylinder valves; IS 7302 for breathing apparatus valves; IS 8776 or IS 8737 for LPG cylinder valves; IS 15100 for auto LPG container valves; IS 12300 for small refrigerant cylinder valves; IS 9798 for LPG regulators.
Gas Cylinder Rules, 2016 · G.S.R. 1081(E) dated 22-11-2016 · Section 18 of the Explosives Act, 1884 · Butterfly Valves (Quality Control) Order, 2020 · S.O. 1920(E) dated 17-06-2020
2
Verify the foreign manufacturer holds a current BIS CM/L licence against the IS standard specific to the product being imported. Confirm the licence covers the applicable product type, pressure class, size range, and manufacturing facility on the BIS online register before placing the purchase order.
ISI Mark Scheme · Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018 · BIS Act, 2016
3
Ensure every unit bears the ISI mark and the supplier's CM/L number traceable to the licensed facility. For valves destined for gas cylinders, the marking must additionally demonstrate compliance with Rule 4(1) of the Gas Cylinder Rules, 2016.
Gas Cylinder Rules, 2016 · G.S.R. 1081(E) dated 22-11-2016 · BIS (Conformity Assessment) Regulations, 2018
4
Quote the supplier's BIS CM/L number and the applicable IS number on the bill of entry. Customs verifies the CM/L in real time against the BIS register; an absent, expired, or IS-scope-mismatched licence triggers consignment detention.

A word of counsel

The single most consequential error on this tariff line is obtaining a CM/L licence against only one Indian Standard — typically IS 13095 for butterfly valves — and then importing a second product variant (say, an LPG cylinder valve or a medical gas valve) on the same licence. Each IS on this tariff line covers a distinct product family; the CM/L is standard-specific and scope-specific. A valve from a manufacturer whose licence does not explicitly cover that product type and IS number will be detained at port regardless of the ISI mark printed on the unit.

Frequently asked

Does HSN 8481 80 20 require BIS certification?

Yes. Non-ferrous metal valves, taps and cocks under this tariff line require Bureau of Indian Standards certification under the ISI Mark Scheme; the applicable IS number depends on the valve type, with IS 13095 mandated for butterfly valves from 01 January 2021 and separate standards mandated for gas-cylinder valves under the Gas Cylinder Rules, 2016.

Which Indian Standard applies to the specific valve being imported?

The standard is product-type-specific: IS 13095 for butterfly valves; IS 3224 for industrial gas and CNG cylinder valves; IS 3745 for medical gas cylinder valves; IS 7302 for breathing apparatus valves; IS 8776 or IS 8737 for LPG cylinder valves (capacity-dependent); IS 15100 for auto LPG containers; IS 12300 for small refrigerant cylinders; IS 9798 for LPG regulators.

Does one CM/L licence cover all valve types and product variants from the same manufacturer?

No. Each CM/L licence is specific to a named IS standard, product scope, and licensed manufacturing facility; a manufacturer with an IS 13095 licence for butterfly valves is not covered for gas-cylinder valves under IS 3224 or any other standard in this group.

Do valves fitted to gas cylinders face any regulatory requirement beyond the BIS QCO?

Yes. Rule 4(1) of the Gas Cylinder Rules, 2016 read with Section 18 of the Explosives Act, 1884 independently mandates that valves fitted to gas cylinders comply with the IS standard applicable to the cylinder type; this obligation runs concurrently with the ISI Mark Scheme requirement.
