HSN 2933 39 23 covers goods specified in Supplementary Note 14 to Chapter 29 and is subject, as the primary regulatory overlay, to Central Drugs Standard Control Organisation (CDSCO) registration requirements under G.S.R. 102(E) dated 11-02-2020 for any listed medical device, and to Central Insecticides Board and Registration Committee (CIB&RC) import-permit or registration requirements under Section 9 of the Insecticides Act, 1968 for any substance used as an insecticide.

Compliance steps

1
Determine whether the specific substance falls within the scope of the Insecticides Act, 1968. If so, obtain either a Certificate of Registration or an Import Permit from the Central Insecticides Board and Registration Committee before shipment; import from any source not specified on the certificate or permit is prohibited under Section 9 of the Insecticides Act, 1968 and Rule 45 of the Insecticides Rules, 1971.
Section 9 of the Insecticides Act, 1968 · Rule 45 of the Insecticides Rules, 1971 · CBIC Circulars 35/2011 dated 09-08-2011 and 7/2014 dated 07-03-2014
2
If the substance is a medical device listed in G.S.R. 102(E) dated 11-02-2020, comply with all CDSCO registration conditions under that notification before filing the bill of entry. Upload the CDSCO registration certificate in e-Sanchit; failure to produce a current registration results in consignment detention at the port of import.
G.S.R. 102(E) dated 11-02-2020 issued by MOHFW · DGFT Notification 44/2025-26 dated 15-10-2025 · ITC (HS) policy condition 7 of Chapter 29
3
Comply with CBIC Circular 23/2023-Cus dated 30-09-2023 by including the mandatory additional qualifiers in the import declaration for Chapter 29 commodities with effect from 15-10-2023. Where the substance is a narcotic drug or psychotropic substance, policy conditions 2 and 3 of Chapter 29 apply; for ozone-depleting substances, policy conditions 1, 4 and 5 of Chapter 29 and the Ozone Depleting Substances (Regulation and Control) Rules, 2000 govern the import.
CBIC Circular 23/2023-Cus dated 30-09-2023 · ITC (HS) policy conditions 1, 2, 3, 4, 5 and 7 of Chapter 29 · Ozone Depleting Substances (Regulation and Control) Rules, 2000

A word of counsel

The single most common error on this tariff line is treating it as a standard Chapter 29 chemical subject only to CBIC Chapter 29 qualifiers, while missing that the specific substance may independently trigger CIB&RC registration, CDSCO medical-device clearance, NDPS policy conditions, or the Public Liability Insurance Act, 1991 insurance requirement under S.O. 227(E) dated 24-03-1992 for hazardous substances imported in excess of threshold quantities. The multi-PGA overlay is substance-specific, not tariff-line-wide, so the importer must map the actual chemical identity against each applicable regime before the purchase order is placed — not at the bill-of-entry stage.

Frequently asked

Does HSN 2933 39 23 require BIS certification?

No, no BIS Quality Control Order covers this tariff line. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968 for insecticidal substances, by the Central Drugs Standard Control Organisation under G.S.R. 102(E) dated 11-02-2020 for listed medical devices, and by ITC (HS) policy condition 7 of Chapter 29 as administered by DGFT.

Is a CIB&RC import permit required even when the substance is imported for a non-insecticidal purpose?

Yes. Where an insecticide listed under the Insecticides Act, 1968 is imported for non-insecticidal purposes, an import permit from the Registration Committee under the Department of Agriculture and Cooperation is still mandatory, and the permit will specify the permitted source of supply.

What additional obligation applies when a hazardous substance under this tariff line is imported in quantities exceeding prescribed thresholds?

The importer must take out an insurance policy under the Public Liability Insurance Act, 1991 as per S.O. 227(E) dated 24-03-1992 issued by the Ministry of Environment, Forest and Climate Change; import of waste forms also attract Rules 12 and 13 of the Hazardous Waste (Management and Transboundary Movement) Rules, 2016.
