A group of bipartisan lawmakers in the U.S. is urging the U.S. Trade Representative to remove trade barriers for U.S. blueberry growers in Japan. They argue that tariffs on frozen blueberries have handicapped the U.S. in competition since the Comprehensive and Progressive Trans-Pacific Partnership was implemented in 2018. The lawmakers are seeking a duty-free amendment to the U.S.-Japan Trade Agreement to equalize the access for frozen blueberries, similar to fresh and dried blueberries. Japan is the third-largest international market for U.S. frozen blueberries, but the U.S. market share has dropped by six percent over the last four years while Canada and the European Union have maintained and increased their shares, respectively.
