A word of counsel

The most common error on this tariff line is assuming the NDPS import certificate and the drug-registration documentation are the complete clearance set, while overlooking the CIB&RC permit obligation that activates if the specific substance figures in the Schedule to the Insecticides Act, 1968. The two regimes are independent: a valid NDPS certificate does not substitute for the CIB&RC registration, and import through a port not permitted under Rule 45 of the Insecticides Rules, 1971, exposes the consignment to seizure even where the NDPS clearance is in order.
