U.S. Customs and Border Protection (CBP) has advised the trade via its Generalized System of Preferences (GSP) informational web page that importers should ensure their mailing addresses and ACH numbers are up to date in order to facilitate GSP refunds.
On March 23, 2018, the President signed into law the Omnibus Spending Bill to fund the federal government, which contains provisions to renew GSP until December 31, 2020. CBP will apply GSP retroactively to entries filed after December 31, 2017. CBP will issue refunds on GSP-eligible merchandise on past entries, provided they were filed using Special Program Indicator (SPI) code “A,” or a request is filed with CBP within 180 days after the Spending Bill was enacted.
