Exports of mineral oil products as aircraft stores permitted under a conditional duty-free regime mirroring prior rules. Amendment inserts condition (v) permitting export of mineral oil products under Chapter 27 as stores for consumption on board an aircraft on foreign run, subject to conditions and limitations to be applied mutatis mutandis from the earlier notification issued under the Central Excise Rules; the change authorizes duty-free export by persons registered under the registered trader regime only upon compliance with that prescribed conditional framework.
