Compliance steps

1
Where the substance falls within the Schedule to the Insecticides Act, 1968, obtain registration and an import permit from the Secretariat of CIB&RC before shipment. Note that import of insecticides is restricted to places notified under Rule 45 of the Insecticides Rules, 1971; routing through an unnotified port renders the consignment liable to detention and confiscation.

A word of counsel

The most common error on this tariff line is importing on the basis of a CIB&RC registration alone without confirming whether the NDPS dual-track applies: if the substance or its preparation is also scheduled under the NDPS framework, the import certificate under Rule 53 of the NDPS Rules, 1985 is independently required and is not subsumed by the pesticide registration. A consignment cleared with CIB&RC documents but lacking the NDPS import certificate faces seizure under the NDPS Act, 1985 irrespective of pesticide-regime compliance.
