A word of counsel

The most common error on this tariff line is assuming the Schedule-to-the-Insecticides-Act check is routine and skipping a pre-shipment verification of CIB&RC Schedule status. N-Ethylperfluorooctane sulphonamide may trigger both the CIB&RC pesticide regime and the NDPS overlay simultaneously — two independent clearance tracks — and a consignment arriving at a non-notified port under Rule 45 of the Insecticides Rules, 1971 is liable to detention and seizure regardless of whether the registration certificate is otherwise in order.
