A word of counsel

The most common error on this tariff line is overlooking the dual-track PGA obligation: importers who secure the DGFT/ITC (HS) policy clearance for a restricted organic chemical sometimes proceed without verifying whether the specific substance is listed in the Schedule to the Insecticides Act, 1968, which triggers a separate and independent CIB&RC registration and port-restriction overlay. Failure to hold CIB&RC registration at the time of import — even when NDPS and CWC conditions are satisfied — results in consignment detention and potential confiscation under the Insecticides Act, 1968.
