The renewal of the Generalized System of Preferences (GSP) program became effective on 29 July 2015. The GSP renewal has retroactive effect for the period during which it lapsed (1 August 2013 through 28 July 2015), and US Customs and Border Protection (CBP) recently provided notice that it will begin processing refunds on duties paid on GSP-eligible merchandise during the lapse period. Importers whose formal and informal entries were filed through the Automated Broker Interface (ABI) using the appropriate Special Program Indicator (SPI) Code are not required to take any action, and CBP will automatically process these refunds. However, non-ABI filers and ABI filers that did not include the appropriate SPI Code on qualifying entries must submit a duty refund request to CBP by 28 December 2015. Refund requests for unliquidated entries may be subject to a different deadline. Companies should be reviewing imports from GSP-eligible countries even if they think they qualify for automatic refunds in order to ensure that they receive all refunds owed to them.
