Compliance steps

1
Determine whether the specific substance being imported figures in the Schedule to the Insecticides Act, 1968. If so, obtain registration and an import permit from the Secretariat of CIB&RC, and route the consignment only through ports permitted under Rule 45 of the Insecticides Rules, 1971. Upload registration certificate (document code 101dc1) and import licence for drugs (document code 9111dc) in e-Sanchit before filing the bill of entry.

2
If the substance is a scheduled narcotic or psychotropic substance, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 (Chapter VII-A) for medical or scientific purposes. Imports outside that category are governed by Appendix-I to the ITC (HS) Schedule and require prior DGFT policy compliance.

3
Ensure the import declaration includes all mandatory additional qualifiers for Chapter 29 commodities as stipulated in paras 4.1 and 4.2 of CBIC Circular 23/2023-Cus dated 30-09-2023, effective 15-10-2023. Where import of specified hazardous substances exceeds the notified threshold quantities, an insurance policy under the Public Liability Insurance Act, 1991 must be in place per S.O. 227(E) dated 24-03-1992.

A word of counsel

The most common error on this tariff line is treating CIB&RC and NDPS as mutually exclusive overlays and clearing the consignment under only one regime. A single shipment of perfluorooctane sulphonamide derivatives may simultaneously trigger CIB&RC Schedule-to-the-Act registration, NDPS Rule 53 import-certificate requirements, and the Chapter 29 mandatory-qualifier obligations under CBIC Circular 23/2023-Cus — failure to satisfy any one of these at the bill-of-entry stage results in detention and ground rent pending PGA NOC, with no retrospective cure available once the consignment is flagged.

Frequently asked

Does HSN 2935 50 90 require BIS certification?

Import is governed by CIB&RC registration and permit under the Insecticides Act, 1968 where the substance is scheduled, with concurrent NDPS Rules, 1985 controls and DGFT ITC (HS) policy condition 2 of Chapter 29.

Which ports are permitted for import of insecticides under this tariff line?

The ports at which insecticides falling under the Schedule to the Insecticides Act, 1968 may be imported are restricted under Rule 45 of the Insecticides Rules, 1971; the permitted ports must be verified with the CIB&RC Secretariat before shipment.

When does the Public Liability Insurance requirement apply to imports under HSN 2935 50 90?

The requirement under the Public Liability Insurance Act, 1991 is triggered when the imported quantity of a specified hazardous substance exceeds the threshold quantities notified by the Ministry of Environment and Forests per S.O. 227(E) dated 24-03-1992; the owner must hold a current insurance policy at the time of import.
