EPCG export obligation closure permitted for SEZ supplies made before policy change without FCA realization; later supplies require FCA. Closure and redemption of EPCG authorisations are permitted for DTA suppliers who made supplies to SEZ units prior to the policy change even if proceeds were not realised through the SEZ unit's Foreign Currency Account, because earlier HBP provisions and SEZ Rules did not require FCA receipt for discharge of export obligation; by contrast, the current FTP/HBP requires FCA realisation for counting such supplies toward export obligations for authorisations issued under FTP 2015-20 and for transactions or receipts occurring after the policy change.
