If the substance is an NDPS-scheduled item, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for medical and scientific purposes; all other NDPS imports are governed by Appendix-I to the ITC (HS) Schedule.

A word of counsel

The most common error on this residual tariff line is assuming that because the substance is classified under the catch-all '2920 29 90', neither the CIB&RC nor NDPS regime applies. Both regimes attach to substance identity, not to HSN classification: a substance can sit in this residual heading and still be a scheduled insecticide or a controlled NDPS compound. Conducting a pre-import substance-identity check against the Schedule to the Insecticides Act, 1968 and the NDPS Rules, 1985 before placing the purchase order is the only reliable way to avoid port detention and seizure.
