A word of counsel

The most common error on this tariff line is assuming the free-import status — confirmed by DGFT Notification 23/2015-2020 — eliminates all PGA gating. The CIB&RC registration and port restriction under Rule 45 of the Insecticides Rules, 1971 apply independently whenever the imported formulation is scheduled under the Insecticides Act, 1968; a consignment arriving at a non-notified port with no CIB&RC registration is liable to detention and seizure even when no Narcotics Commissioner NOC is required.
