Levy of service tax on foreign-to-foreign vessel transport: Indian importer designated liable to pay tax on customs value. Notification withdraws exemption for sea-transport services provided by persons in non-taxable territories to persons in non-taxable territories up to Indian customs clearance; the Indian person who effects customs compliance is liable to pay service tax. Foreign shipping lines cannot meet the conditional exemption tied to non-availability of Cenvat credit because their services are zero-rated abroad and they are not registered under Cenvat Credit Rules, so tax applies on the full service value with the prescribed customs-value-based payment option and applicable ancillary cesses.
