Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 7466:1994 for rubber gaskets for pressure cookers. Verify the supplier's CM/L number, licensed product scope, and licensed manufacturing facility on the BIS online register before placing the purchase order.

2
Ensure every rubber gasket in the consignment bears the ISI mark and the supplier's CM/L number. The standard mark must appear on the product itself; marking only on outer packaging does not satisfy the statutory marking requirement.

3
Verify the applicable enforcement date for your supplier's enterprise category: 15 April 2024 for small enterprises, 15 July 2024 for all others, and 15 December 2024 for micro enterprises. Consignments shipped before the relevant date from a micro or small enterprise supplier must be documented accordingly.

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 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 sourcing from a supplier whose CM/L licence covers rubber O-rings or general vulcanised rubber seals under IS 7466:1994 without confirming that the licensed scope explicitly includes pressure cooker gaskets. IS 7466:1994 governs rubber rings broadly, but the Rubber Gasket for Pressure Cookers (Quality Control) Order, 2023 mandates a product-specific licensed scope; a CM/L issued for O-rings or generic seals does not satisfy the QCO obligation for pressure cooker gaskets, and customs will detain the consignment on a scope mismatch.

Frequently asked

Does HSN 4016 93 40 require BIS certification?

Yes. Rubber gaskets for pressure cookers under this tariff line must conform to IS 7466:1994 under the ISI Mark Scheme, as mandated by the Rubber Gasket for Pressure Cookers (Quality Control) Order, 2023 with effect from 15 July 2024 for general enterprises.

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

No. The enforcement date is 15 April 2024 for small enterprises, 15 July 2024 for all other enterprises, and 15 December 2024 for micro enterprises as defined under the applicable MSME classification.

Does IS 7466:1994 cover all rubber gaskets, or only pressure cooker gaskets under this QCO?

IS 7466:1994 specifies requirements for rubber rings broadly, but the Rubber Gasket for Pressure Cookers (Quality Control) Order, 2023 applies the standard specifically to pressure cooker gaskets under HSN 4016 93 40. General-purpose rubber gaskets outside this product scope are not covered by this QCO.

Does a single CM/L licence cover all gasket sizes and pressure ratings from the same manufacturer?

No. A CM/L licence is scope-specific by product variant, size, and manufacturing facility; gaskets outside the licensed specification or from an unlicensed plant are not covered and will be detained at customs.
