Compliance steps

1
Determine whether the consignment falls within the Schedule to the Insecticides Act, 1968; if so, obtain CIB&RC registration and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee before shipment. Route the import only through places notified under Rule 45 of the Insecticides Rules, 1971, as import at non-notified locations is not permitted.

2
If the substance is scheduled under the NDPS framework, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 through the Central Bureau of Narcotics (cbn.nic.in) for imports intended for medical and scientific purposes. Imports outside that category are governed by Appendix I to the ITC (HS) Schedule per policy condition 2 of Chapter 29.

Ensure the import declaration includes the mandatory additional qualifiers prescribed for Chapter 29 commodities under CBIC Circular 23/2023-Cus dated 30-09-2023, with effect from 15 October 2023. Where import of specified hazardous substances exceeds prescribed quantities, take out an insurance policy under the Public Liability Insurance Act, 1991 per S.O. 227(E) dated 24-03-1992.

A word of counsel

The most frequent error on this tariff line is importing on the basis of the NDPS medical-and-scientific-purpose certificate alone, without separately verifying whether the substance also figures in the Schedule to the Insecticides Act, 1968 — a distinct and independent trigger that requires CIB&RC registration and a separate import permit. Both regimes can apply simultaneously to the same consignment, and arrival at a port not notified under Rule 45 of the Insecticides Rules, 1971 constitutes a separate contravention regardless of the NDPS clearance status.
