    If the substance is a notified NDPS item, import is restricted to medical and scientific purposes under Chapter VII-A of the NDPS Rules, 1985; obtain an import certificate under Rule 53 of the NDPS Rules, 1985. Imports outside that category are governed by Appendix-I of the ITC (HS) Schedule and ITC (HS) policy condition 2 to Chapter 29.

A word of counsel

The most common error on this tariff line is importing without first confirming the substance's Schedule status under the Insecticides Act, 1968 — the port-of-import restriction under Rule 45 of the Insecticides Rules, 1971 applies only to scheduled insecticides, and consignments routed through an unpermitted port are liable to seizure regardless of whether a CIB&RC permit was obtained. Additionally, the Appendix-II ITC (HS) check and the NDPS overlay are independent inquiries: a substance may clear one gate while still failing the other, and the mandatory Chapter 29 qualifier declarations under CBIC Circular 23/2023-Cus are required in all cases.

At which ports may this substance be imported if it is a scheduled insecticide?
Import of scheduled insecticides is restricted to the ports specifically notified for that purpose under Rule 45 of the Insecticides Rules, 1971; the current list should be confirmed with the CIB&RC Secretariat before shipment.
When does the Public Liability Insurance Act, 1991 obligation arise for this import?
