Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 3315:2019 and IS 17570 (Part 1):2021. Verify the supplier's CM/L number, licensed product scope, and manufacturing facility address on the BIS online register before placing the purchase order.
Air Cooler and Air Filters (Quality Control) Order, 2025 · S.O. 529(E) dated 30-01-2025 · Scheme-I of Schedule-II of the BIS (Conformity Assessment) Regulations, 2018
2
Ensure each unit bears the ISI mark and the supplier's CM/L number per Scheme-I of Schedule-II of the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product itself, not on packaging alone.

3
Obtain Extended Producer Responsibility authorisation from the Central Pollution Control Board for import of indoor air purifiers before the consignment arrives. Micro enterprises as defined in the Micro, Small and Medium Enterprises Development Act, 2006 are exempt from EPR. Quote the EPR authorisation number on the bill of entry.
Schedule-I of the E-Waste (Management) Rules, 2022 · G.S.R. 801(E) dated 02-11-2022
4
Quote the supplier's BIS CM/L number and the CPCB EPR authorisation number on the bill of entry. Customs verifies both against their respective portals in real time; an absent, expired, or scope-mismatched CM/L triggers consignment detention.

5
Assess applicability of the phased enforcement windows and exemptions: the 200-unit annual R&D import carve-out requires the importer to maintain year-wise records and obtain a manufacturer's undertaking that goods will not be sold commercially. Transitional declared-stock relief for pre-QCO inventory expires 31 October 2025.

A word of counsel

The single most common error on this tariff line is failing to note that the QCO imposes two concurrent Indian Standards — IS 3315:2019 for air purifiers and IS 17570 (Part 1):2021 — and that a CM/L covering only one of these does not satisfy the full scope of the Air Cooler and Air Filters (Quality Control) Order, 2025. Importers who verify only the IS 3315 licence number and overlook the IS 17570 (Part 1) requirement find their consignments detained at port when Customs cross-checks the full scope against the BIS register.

Frequently asked

Does HSN 8421 39 20 require BIS certification?

Yes. Conformity to IS 3315:2019 and IS 17570 (Part 1):2021 is mandatory under the ISI Mark Scheme from 30 January 2025, under the Air Cooler and Air Filters (Quality Control) Order, 2025; import from manufacturers without a current BIS CM/L licence is not permitted.

Is Extended Producer Responsibility authorisation required separately from BIS QCO compliance?

Yes. EPR authorisation for indoor air purifiers is administered by the Central Pollution Control Board under Schedule-I of the E-Waste (Management) Rules, 2022 and is entirely independent of the BIS CM/L licence. Micro enterprises as defined in the MSMED Act, 2006 are exempt.

What are the phased enforcement dates and who qualifies for the later deadlines?

General enterprises must comply from 1 April 2025; Small Enterprises from 1 July 2025; Micro Enterprises from 1 October 2025. An enterprise registered on the Udyam Portal whose plant and machinery investment does not exceed ₹1 crore and turnover does not exceed ₹5 crore for the previous financial year, as certified by a Chartered Accountant, qualifies for the Micro Enterprise timeline.

Does a single CM/L licence cover both IS 3315:2019 and IS 17570 (Part 1):2021?

Not automatically. A CM/L licence is scope-specific; importers must confirm with the BIS register that the supplier's licence explicitly covers both IS 3315:2019 and IS 17570 (Part 1):2021 for the product models in the consignment.
