Compliance steps
  1. 1
    Confirm whether the consignment falls within the Schedule to the Insecticides Act, 1968; if so, obtain registration and an import permit from the secretariat of the Central Insecticides Board and Registration Committee before shipment. Route the consignment only through locations notified under Rule 45 of the Insecticides Rules, 1971, as import at non-notified points renders the consignment liable to seizure.
    Insecticides Act, 1968 · Rule 45 of the Insecticides Rules, 1971 · ITC (HS) policy condition 2 of Chapter 29
  2. 2
    If the substance is scheduled under the NDPS regime, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 before filing the bill of entry. Imports for purposes other than medical and scientific use are governed by Appendix I to the ITC (HS) Schedule and require DGFT clearance under ITC (HS) policy condition 2 of Chapter 29.

A word of counsel

The most common error on this tariff line is treating the drug-regime document set (certificate of analysis, batch release, import licence for drugs) as exhaustive and overlooking the parallel CIB&RC registration obligation where the substance is scheduled under the Insecticides Act, 1968. Both regimes are independently operative; a consignment cleared by CDSCO-linked documentation but lacking CIB&RC registration and a Rule 45-notified port of import is liable to detention and confiscation under the Insecticides Act regardless of drug-licence compliance. Verify schedule status under both Acts before placing the purchase order.
