Exchange rate determination: Customs-prescribed conversion rates set for specified foreign currencies for import and export valuation purposes. The Central Board of Indirect Taxes and Customs, under the Customs Act authority, prescribes distinct exchange rates for specified foreign currencies for import and export valuation, effective from the operative date, as set out in Schedule I (per unit) and Schedule II (per 100 units); the notification supersedes the prior notification except as to prior actions and is itself noted as superseded by a subsequent administrative notification.
