Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against the applicable standard — IS 17790:2022 for insulated flasks, IS 17526:2021 for stainless steel vacuum flasks/bottles, or IS 17569:2021 for insulated food-storage containers. Verify the CM/L number, product scope, and licensed facility on the BIS online register before placing the purchase order.

2
Ensure each unit bears the ISI mark and the manufacturer's CM/L number under Scheme-I of Schedule-II of the Bureau of Indian Standards (Conformity Assessment) Regulations, 2018. Marking must appear on the product itself, not on packaging alone.

3
Confirm which Indian Standard governs the specific product type being imported — IS 17790:2022 covers general insulated flasks for domestic use, IS 17526:2021 covers stainless steel vacuum flasks/bottles, and IS 17569:2021 covers insulated containers for food storage. A CM/L licence is standard-specific; importing under an incorrectly cited standard triggers non-compliance at port.

4
Quote the supplier's BIS CM/L number and the applicable IS standard on the bill of entry. Customs verifies the CM/L in real time against the BIS register; an absent, expired, or scope-mismatched CM/L triggers consignment detention.

5
If the importer claims a micro-enterprise exemption, confirm the enterprise is registered on the Udyam Portal with investment in plant and machinery not exceeding ₹1 crore and turnover not exceeding ₹5 crore for the previous financial year, certified by a Chartered Accountant. The exemption does not apply to medium or small enterprises — small enterprises were brought within scope from 06 September 2024 and micro enterprises from 06 December 2024.

A word of counsel

The single most common error on this tariff line is treating all three Indian Standards as interchangeable when verifying a supplier's CM/L licence. IS 17790:2022, IS 17526:2021, and IS 17569:2021 are distinct standards with separate licensing scopes — a manufacturer licensed against IS 17526:2021 for stainless steel vacuum bottles is not automatically licenced to supply food-storage containers under IS 17569:2021. Importing a product type outside the licensed standard's scope renders the consignment non-compliant regardless of the ISI mark on the label, exposing the importer to detention and re-export.

Frequently asked

Does HSN 9617 00 11 require BIS certification?

Yes. Conformity to IS 17790:2022, IS 17526:2021, or IS 17569:2021 (as applicable to the product type) is mandatory under the ISI Mark Scheme with effect from 06 June 2024 under the Insulated Flask, Bottles and Containers for Domestic Use (Quality Control) Amendment Order, 2024; import requires a current BIS CM/L licence.

Which Indian Standard applies to stainless steel vacuum flasks specifically?

IS 17526:2021 governs domestic stainless steel vacuum flasks and bottles. IS 17790:2022 covers insulated flasks for domestic use generally, and IS 17569:2021 covers insulated containers for food storage; each standard carries its own separate CM/L licence scope.

Are micro-enterprise importers exempt from the BIS QCO obligation?

Yes, conditionally. Enterprises registered on the Udyam Portal with investment in plant and machinery not exceeding ₹1 crore and turnover not exceeding ₹5 crore for the previous financial year, as certified by a Chartered Accountant, are exempt. Small enterprises lost exemption from 06 September 2024; micro enterprises from 06 December 2024.

Does a single CM/L licence cover all three insulated-flask product types?

No. Each CM/L licence is standard-specific and facility-specific; a licence against IS 17790:2022 does not authorise import of products that must conform to IS 17526:2021 or IS 17569:2021, and a product variant outside the licensed scope is non-compliant at customs.
