President Trump extended the Jones Act waiver allowing foreign vessels to move oil and other goods in U.S. waters for 90 days, but narrowed the exemption to energy cargoes after Iran-related disruptions to crude flows pushed fuel costs higher. The new waiver targets gasoline, jet fuel, crude, napatha, LNG, soybean oil and fertilizer. The Pentagon must consult the U.S. Maritime Administration before approving waivers for individual voyages. The White House said the move secures supplies for the military and key industries and increases domestic transport of gasoline, diesel and jet fuel; U.S. shipbuilders and some members of Congress say the waiver weakens protections for the domestic shipping industry.
