On May 10, 2017, the Governments of U.S. and Israel signed an agreement indicating that certificates of origin would no longer be required in order to claim duty preference under the U.S. – Israel Free Trade Agreement. According to this agreement, which was published by the Office of the United States Trade Representative (USTR), a written declaration would be “completed by the producer or export on the invoice, delivery note, or any other commercial document.” According to the America-Israel Chamber of Commerce website, these changes will become effective on March 31, 2018.
