Limit on Indian currency use at duty free shops aligned with RBI export/import permissions, requiring INR pricing and exchange disclosure. The previous ceiling on payments in Indian rupees at duty free shops has been revised to align with RBI permission on carrying Indian currency across borders; DFS operators must permit purchases in Indian currency up to the RBI-prescribed limit, display prices in Indian rupees alongside foreign currencies, publish the CBEC-notified fortnightly exchange rate, update websites and notices about the facility and limit, and follow prescribed duty-free procurement procedures for excisable goods.
