Compliance steps

1
Obtain registration and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee before shipment. Import of insecticides listed in the Schedule to the Insecticides Act, 1968 is permitted only at ports specified under Rule 45 of the Insecticides Rules, 1971; entry through any other port renders the consignment liable to seizure.

2
If the substance qualifies as a narcotic drug or psychotropic substance under the NDPS schedules, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 before filing the bill of entry. Imports for medical and scientific purposes are permissible under Chapter VII-A of the NDPS Rules, 1985; all other imports are governed by Appendix I to the ITC (HS) Schedule per ITC (HS) policy condition 2 to Chapter 29.

3
Ensure mandatory additional qualifiers are included in the import declaration in compliance with CBIC Circular 23/2023-Cus dated 30-09-2023, which applies to all commodities under Chapter 29 with effect from 15 October 2023. Also verify, where consignment quantities exceed the threshold specified under S.O. 227(E) dated 24-03-1992, that the importer has taken out a public liability insurance policy under the Public Liability Insurance Act, 1991.

A word of counsel

The most common error on this tariff line is assuming that CIB&RC registration alone suffices and overlooking the NDPS overlay. Where the phosphonothionate compound appears in the NDPS schedules, a separate import certificate under Rule 53 of the NDPS Rules, 1985 is required in addition to the insecticide permit — and the two clearances are independent; absence of either attracts detention, monetary penalty, or criminal liability under the NDPS Act, 1985. Confirm schedule classification at the Narcotics Control Bureau portal before shipment.

Frequently asked

Does HSN 2931 53 00 require BIS certification?

No, organo-inorganic compounds under this tariff line fall outside the BIS Quality Control Order regime. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with a potential NDPS Rules, 1985 overlay where the substance is scheduled.

Which ports are notified for import of insecticides under Rule 45 of the Insecticides Rules, 1971?

The places of import for scheduled insecticides are restricted to ports notified under Rule 45 of the Insecticides Rules, 1971; the current list should be confirmed with the CIB&RC Secretariat before placing the purchase order, as routing to an unspecified port triggers consignment detention.

When does the public liability insurance requirement apply to imports of this substance?

Where the imported quantity of a specified hazardous substance exceeds the threshold quantities prescribed under S.O. 227(E) dated 24-03-1992 issued by the Ministry of Environment and Forests, the importer must take out a public liability insurance policy under the Public Liability Insurance Act, 1991 before clearance.
