A word of counsel

The most common error on this tariff line is attempting to import oxytocin under the general NDPS medical-purpose pathway: oxytocin is subject to a standalone prohibition under S.O. 2357(E) and DGFT Notification 09/2015-2020, and the only permitted entry is oxytocin reference standards exclusively for test and analysis against a test licence from DGCI/CDSCO. Consignments of oxytocin presented without a CDSCO test licence — even where an NDPS import certificate exists — face seizure and confiscation at the port of import.
