A word of counsel

The most common error on this tariff line is assuming that CIB&RC registration alone clears the consignment, while overlooking the port-of-import restriction under Rule 45 of the Insecticides Rules, 1971. Routing a CIB&RC-registered pesticide consignment through an unnotified port renders the import unlawful regardless of licence currency — attracting detention and potential confiscation under the Insecticides Act, 1968. Importers should also verify at the purchase-order stage whether the substance simultaneously triggers NDPS Rule 53 obligations, since the two regimes operate independently and both must be satisfied before out-of-charge.
