A word of counsel

The dual-regime trap on this tariff line is the concurrent applicability of CIB&RC registration and the NDPS import-certificate requirement: importers who secure only the CIB&RC permit and overlook the NDPS certificate — or vice versa — face consignment detention at the port of import. The Insecticides Rules, 1971 also restrict the ports through which the substance may enter; routing through an unlisted port renders both clearances ineffective and exposes the consignment to seizure independently of the licence status.
