GSP had finally renewed again.
President Obama signed into law the reinstatement of GSP effective July 29, 2015 and retroactive to July 31, 2013.
Though it was approved retroactively, it does not allow the automatic refund of duties on entries properly flagged during the period GSP was suspended. Therefore, filers will be required to request duty refunds for each eligible entry.
It is expected that CBP will soon issue instructions on preparing, and processing such requests. Please see the below article for more details.
