# The Jones Act taxes every port. Repeal it.

A century of cabotage law has raised costs for Alaska, Hawaii, Puerto Rico, and the whole U.S. economy with no proven military benefit.

The Jones Act turns 104 years old this year. It is time to let it go.

The law, Section 27 of the Merchant Marine Act of 1920, requires that all goods moved by water between U.S. ports travel on ships that are U.S.-built, U.S.-flagged, U.S.-owned, and U.S.-crewed [^16]. Congress expanded it in 1940 to cover towing vessels and in 1988 to cover dredge spoil and municipal waste [^18][^19]. What started as a wartime measure has become a permanent tax on every American who buys something that moved through a U.S. port.

The cost is real and measurable. A 2011 MARAD study found the average operating cost of a U.S.-flagged ship was 2.7 times greater than a foreign-flag ship [^1]. A 2022 GAO report put the extra cost at about $6.2 to $6.5 million per vessel per year, or nearly $17,000 per day [^6]. One study equates the Jones Act to a 64.6% tariff on domestic seaborne trade [^9]. The World Economic Forum estimates the law costs the U.S. economy $200 million per year in extra shipping costs [^12].

Alaska has paid the price for decades. In 1982, the Alaska Statehood Commission estimated the Jones Act drained $225 million a year from the state's oil industry and $41 million from other sectors [^7]. A 1988 GAO study found extra shipping costs of $163 million per year for goods moving between Alaska and the mainland [^11]. The U.S. Forest Service estimated in 1986 that the law cost Alaska's timber industry $4.77 million annually [^8]. The read here is that every Alaskan family has paid a hidden surcharge on nearly everything they buy.

The national security argument for the law has collapsed. The U.S. now ranks nineteenth in commercial shipbuilding and builds fewer than five ships per year, while China builds more than 1,700 [^3]. In 2017, the Maritime Workforce Working Group reported a deficit of 1,839 mariners for sustained wartime sealift [^2]. The law that was supposed to guarantee a strong merchant marine has instead left the country with a shrunken fleet and a shortage of trained crews. A report found no evidence of military necessity for the extended waiver [^13]. The case for keeping the Jones Act appears to rest on sentiment, not on facts.

Puerto Rico feels the law's weight every day. A 2013 GAO report found that about two-thirds of ships calling at the island are foreign-flagged [^14]. Those ships cannot carry cargo between Puerto Rico and the mainland. The result is a captive market for a handful of expensive U.S.-flag carriers. The 1999 GAO study on Alaskan oil tells the story: shipping oil to the Gulf Coast cost $7.15 per barrel and took 41 days, while shipping to the exempt Virgin Islands cost $2.35 per barrel and took 84 days [^4]. The longer route was cheaper because it was not Jones Act-compliant.

The law should go. Congress should repeal Section 27 and let American ports, businesses, and families buy shipping at world prices.
