<h1>Exchange rate determination establishes official conversion rates for import and export valuation under customs law, effective as notified.</h1> Determination of exchange rates for valuation of imported and export goods under the Customs Act fixes distinct rupee equivalents for listed foreign currencies, set out in two annexed schedules that distinguish single unit and hundred unit quotations. The notification supersedes the prior board notification except for past actions and prescribes an effective date from which the specified rates govern customs conversion, requiring customs authorities and stakeholders to adopt those schedule rates for duties, declarations, and other customs processes dependent on foreign currency conversion.
