Compliance steps

1
Determine whether the goods fall within the listed-insecticide schedule under Section 3(e) of the Insecticides Act, 1968. If so, obtain mandatory registration from the Central Insecticides Board and Registration Committee; if imported for a non-insecticidal purpose, obtain a specific import permit from the Registration Committee. No import is permitted from a source other than that specified in the certificate of registration or permit.
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 goods are listed medical devices under G.S.R. 102(E) dated 11-02-2020 issued by the Ministry of Health and Family Welfare, ensure full compliance with CDSCO registration conditions before filing the bill of entry. Upload all mandatory documents in e-Sanchit and ensure Chapter 29 mandatory additional qualifiers are declared per CBIC Circular 23/2023-Cus dated 30-09-2023, operative from 15-10-2023.

3
Where the substance is a narcotic drug or psychotropic substance, comply with policy conditions 2 and 3 of Chapter 29. Where import involves specified hazardous substances exceeding prescribed quantities, take out an insurance policy under the Public Liability Insurance Act, 1991, per S.O. 227(E) dated 24-03-1992; for ozone-depleting substances, comply with policy conditions 1, 4 and 5 of Chapter 29 and the Ozone Depleting Substances (Regulation and Control) Rules, 2000.
S.O. 227(E) dated 24-03-1992 (MEFCC) · Ozone Depleting Substances (Regulation and Control) Rules, 2000 · Hazardous Waste (Management and Transboundary Movement) Rules, 2016, Rules 12 and 13

A word of counsel

The most common error on this tariff line is treating it as a single-regime entry when Supplementary Note 18 to Chapter 29 encompasses substances attracting wholly different regulatory tracks — insecticide registration, medical-device CDSCO compliance, NDPS controls, and hazardous-substance insurance — simultaneously or in the alternative. Importers must characterise the intended use of the specific substance before filing the bill of entry; a consignment cleared as a non-insecticidal chemical that is later found to be used as an insecticide is treated as an unregistered import under the Insecticides Act, 1968, attracting seizure and prosecution regardless of the CDSCO or CBIC qualifiers already submitted.

Frequently asked

Does HSN 2934 99 40 require BIS certification?

No, no BIS Quality Control Order covers goods under this tariff line. Import is governed by the Central Drugs Standard Control Organisation and the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968 and the Medical Devices Rules, 2017, with NDPS and MEFCC overlays as applicable.

Is a separate import permit required even when the insecticide is imported for non-insecticidal purposes?

Yes. Under Section 9 of the Insecticides Act, 1968, an import permit from the Registration Committee is mandatory for non-insecticidal use, and the permit will specify the approved source; import from any other source is a violation regardless of end-use declarations at the bill of entry.

What triggers the Public Liability Insurance Act, 1991 obligation for imports under this HSN?

The insurance obligation under S.O. 227(E) dated 24-03-1992 is triggered when the imported substance is a specified hazardous substance and the quantity imported exceeds the prescribed threshold; the owner must hold a valid insurance policy before the consignment is released from customs.
