Compliance steps

1
Where dichlorodifluoromethane falls within the Schedule to the Insecticides Act, 1968, obtain registration and an import permit from the secretariat of the Central Insecticides Board and Registration Committee before shipment. Import is restricted to ports notified under Rule 45 of the Insecticides Rules, 1971; routing through any non-notified port renders the consignment liable to seizure.

2
If the substance is scheduled under the NDPS framework, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for medical or scientific-purpose imports. Imports outside that category are governed by Appendix-I to the ITC (HS) Schedule under ITC (HS) policy condition 2 of Chapter 29.

A word of counsel

The most common error on this tariff line is assuming the DGFT Restricted-import clearance under policy conditions 1 and 4 of Chapter 29 is the only gate — and overlooking that a separate CIB&RC registration and port-of-import restriction under Rule 45 of the Insecticides Rules, 1971 applies if the substance appears in the Schedule to the Insecticides Act, 1968. Consignments cleared under the DGFT condition but arriving at a non-notified port remain subject to detention and seizure under the Insecticides Act independently of the ITC (HS) compliance status.
