A word of counsel

The recurring error on this tariff line is failing to conduct a pre-import Schedule check under the Insecticides Act, 1968 — importers assume the substance is outside the CIB&RC scope because it is primarily a pharmaceutical intermediate, only to find the consignment detained at the port of import when the proper officer identifies a Schedule match. The restricted-places rule under Rule 45 of the Insecticides Rules, 1971 operates independently of the registration requirement: a valid CIB&RC registration does not authorise import through an unnotified port.
