Compliance steps

1
Determine whether the goods fall within the scope of Supplementary Note 13 to Chapter 29 as a listed insecticide under Section 3(e) of the Schedule to the Insecticides Act, 1968. If so, obtain mandatory registration or, where imported for a non-insecticidal purpose, an import permit from the CIB&RC under Section 9 of the Insecticides Act; import is restricted to the source and ports specified on the registration certificate or permit under Rule 45 of the Insecticides Rules, 1971.
Section 9 of the Insecticides Act, 1968 · Rule 45 of the Insecticides Rules, 1971 · CBIC Circular 35/2011 dated 09-08-2011 · CBIC Circular 7/2014 dated 07-03-2014
2
Where the goods are listed medical devices under G.S.R. 102(E) dated 11-02-2020, ensure CDSCO registration is current and that all conditions specified in that notification are met at the bill of entry. Upload all mandatory documents in e-Sanchit and comply with Chapter 29 mandatory additional qualifier declarations per CBIC Circular 23/2023-Cus dated 30-09-2023, applicable from 15-10-2023.
G.S.R. 102(E) dated 11-02-2020 (MOHFW) · CBIC Circular 23/2023-Cus dated 30-09-2023, para 4.1 and 4.2
3
Verify whether the consignment triggers NDPS policy conditions 2 and 3, ODS controls under Chapter 29 policy conditions 1, 4, and 5, or the Public Liability Insurance Act, 1991 requirement for specified hazardous substances exceeding threshold quantities under S.O. 227(E) dated 24-03-1992 issued by MoEF. Waste imports additionally require compliance with Rules 12 and 13 of the Hazardous Waste (Management and Transboundary Movement) Rules, 2016.
DGFT Notification 44/2025-26 dated 15-10-2025 · S.O. 227(E) dated 24-03-1992 · Hazardous Waste (Management and Transboundary Movement) Rules, 2016, Rules 12 and 13 · Ozone Depleting Substances (Regulation and Control) Rules, 2000

A word of counsel

The most common error on this tariff line is importing on the basis that the overall CTI status is 'Free' under DGFT Notification 44/2025-26, without examining whether the specific substance falls within Supplementary Note 13 as a listed insecticide or a notified medical device — both of which impose mandatory pre-import registration or permitting regardless of the general ITC (HS) policy. A consignment cleared under the Free-import status without a CIB&RC registration or permit, where registration was required, constitutes an illegal import under the Insecticides Act, 1968 and is liable to seizure and prosecution; the CIB&RC registration must also specify the permitted import source, and deviation from that source is independently actionable.

Frequently asked

Does HSN 2933 31 10 require BIS certification?

No, no BIS Quality Control Order covers pyridine salts or the goods specified in Supplementary Note 13 to Chapter 29. Import is governed by CDSCO registration for listed medical devices under G.S.R. 102(E) dated 11-02-2020, CIB&RC registration or permit under the Insecticides Act, 1968, and NDPS and ODS policy overlays as applicable.

Is a CIB&RC import permit required even when the substance is not being used as an insecticide?

Yes. Where a listed insecticide under the Insecticides Act, 1968 is imported for a non-insecticidal purpose, an import permit from the CIB&RC Registration Committee is still mandatory under Section 9 of the Act, and the permit will specify permissible import conditions including the authorised source.

What happens if the goods are both a listed insecticide and a notified medical device?

Both the CIB&RC registration and the CDSCO registration under G.S.R. 102(E) dated 11-02-2020 apply concurrently; satisfying one does not substitute for the other, and customs out-of-charge requires evidence of compliance with each applicable PGA regime.
