Duty Credit Scrip filing timeframe clarified to specify filing windows and cut-off for prior shipments. Applications for obtaining Duty Credit Scrip must be filed within twelve months from date of export or within six months from date of realization or three months from date of printing/release of the shipping bill, whichever is later; for shipments made prior to inclusion/modification by Public Notices the last date is six months from the end of the month of the relevant Public Notice or the foregoing time period, whichever is later; a separate final cut-off applies for SFIS claims.
