- 1Verify whether the specific substance falling under this CTI figures in the Schedule to the Insecticides Act, 1968.

- 2Where the substance is an NDPS-listed item imported for medical or scientific purposes, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 before filing the bill of entry. Imports outside the medical-and-scientific category are governed by Appendix I to the ITC (HS) Schedule per ITC (HS) policy condition 2 to Chapter 29.Chapter VII-A of the NDPS Rules, 1985 · Rule 53 of the NDPS Rules, 1985 · ITC (HS) policy condition 2 to Chapter 29

Where quantities of specified hazardous substances exceed prescribed thresholds, take out an insurance policy under the Public Liability Insurance Act, 1991 as per S.O. 227(E) dated 24-03-1992.CBIC Circular 23/2023-Cus dated 30-09-2023 · S.O. 227(E) dated 24-03-1992
The most common error on this tariff line is assuming the substance is free to import simply because the importer's primary use is industrial and not pesticidal — CIB&RC registration is triggered by the substance's presence in the Schedule to the Insecticides Act, 1968, not by the importer's intended end-use. A consignment arriving at a port not notified under Rule 45 of the Insecticides Rules, 1971 is liable to detention and confiscation regardless of whether CIB&RC registration has been obtained, because port eligibility is a separate and independent condition.
