Compliance steps

1
Verify whether the specific substance falls within the schedule to the Insecticides Act, 1968. If it does, obtain registration and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee before shipment, and route the consignment only through ports specified under Rule 45 of the Insecticides Rules, 1971.

Additionally, confirm whether the substance falls under Appendix-II of the ITC (HS) import policy and ensure compliance before filing the bill of entry.

A word of counsel

The most common error on this tariff line is importing on the assumption that neither the CIB&RC schedule nor the NDPS framework applies, without conducting a substance-specific pre-shipment check against both the Insecticides Act, 1968 schedule and the NDPS lists. A consignment that arrives without the required CIB&RC permit or NDPS import certificate is liable to detention, confiscation, and criminal liability under the respective statutes — and the port restriction under Rule 45 of the Insecticides Rules, 1971 means that diversion to an unspecified port compounds the violation independently of the permit status.
