A word of counsel

The most frequent error on this tariff line is assuming the CIB&RC requirement is prospective and optional — importers ship first and seek registration later. Under Rule 45 of the Insecticides Rules, 1971, import at an unnotified port or without a current registration and permit is an independent contravention of the Insecticides Act, 1968, attracting seizure and prosecution regardless of whether other NDPS or CWC conditions are satisfied. Confirm Schedule coverage, port eligibility, and CIB&RC permit currency before the purchase order is placed.
