“Passed in 1920, the Jones Act severely limits competition in the American shipping market by requiring that ships operating between U.S. ports be American-built, American-crewed, and American-flagged. The number of ships that meet the Jones Act’s standards has been declining for decades, and now fewer than 100 are in operation. Anyone who wants to ship goods—including rum—from Hawaii, Puerto Rico, or other outlying U.S. territories to the mainland is required to use one of those few dozen vessels.
Unsurprisingly, the lack of competition drives up shipping costs. The lawsuit points out that it costs roughly three times as much to ship rum from Hawaii to Los Angeles as it does to ship the same goods from Los Angeles to Australia—an international route where greater competition keeps prices lower, even though the trip is significantly longer.”
