A word of counsel

The most common error on this tariff line is conflating the NDPS import certificate with the CDSCO drug import licence: the two are independent instruments issued by different authorities, and presenting only one at the bill of entry triggers detention pending production of the other. Imports falling outside the medical-and-scientific-purpose category are not eligible for the Chapter VII-A route at all and are instead governed by Appendix-I to the ITC (HS) Schedule under policy condition 2 of Chapter 29 — a distinction that must be resolved before the purchase order is placed, not at the port.
