Compliance steps

1
If the consignment falls within the schedule to the Insecticides Act, 1968, obtain registration and an import permit from the secretariat of the Central Insecticides Board and Registration Committee before shipment. Route the consignment only through ports notified under Rule 45 of the Insecticides Rules, 1971; diversion to an unnotified port renders the import liable to seizure.

2
Where the substance is classified as an NDPS substance, import for medical or scientific purposes requires an import certificate obtained under Rule 53 of the NDPS Rules, 1985. Imports outside the medical and scientific category are governed by Appendix-I of the ITC (HS) Schedule; upload all applicable documents in e-Sanchit — certificate of analysis (0010dc), batch release certificate (0030dc), label of consignment (0110dc), registration certificate (101dc1), and import licence for drugs (9111dc) — before out-of-charge.

3
Ensure the import declaration includes mandatory additional qualifiers for Chapter 29 commodities as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus. Additionally, where import of specified hazardous substances exceeds the specified 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 common error on this tariff line is assuming diphenyl oxide falls outside the Insecticides Act, 1968 schedule without verifying — and filing the bill of entry without the CIB&RC registration certificate and import permit. Even where the substance is not scheduled under the Insecticides Act, the CBIC Circular 23/2023-Cus Chapter 29 mandatory qualifiers must appear in the import declaration from 15 October 2023 onward; omission results in bill-of-entry rejection and consignment detention at the port.
