# The Jones Act is a 64.6% tariff on American ports. Repeal it.

A 1920 law that acts as a 64.6% tariff on domestic seaborne trade raises costs for Puerto Rico, Alaska, and every American port, and should be repealed.

The Jones Act is a 64.6% tariff on domestic seaborne trade [^8]. That is not a metaphor. It is the measured effect of a law that blocks foreign-built, foreign-crewed ships from carrying goods between U.S. ports [^16].

Shipping a container from Jacksonville to Puerto Rico costs nearly $3,000. The same container to the Dominican Republic costs half that [^6][^12]. The difference is the Jones Act. The law raises gasoline prices by up to 15 cents per gallon [^13]. It raises the price of liquefied natural gas for Puerto Rico by up to 30% [^14]. A 1988 GAO study found extra shipping costs of $163 million per year for goods between Alaska and the mainland [^11].

The law is designed to restrict supply so American shippers can charge higher prices [^5]. It created a government-ordered cartel that led to criminal price-fixing convictions among Jones Act carriers between 2011 and 2012 [^3]. Even the Defense Department prefers foreign transport ships because they cost less [^7].

This column has argued before that the Jones Act taxes every port. The numbers keep proving it. A 64.6% tariff on American trade is not a shipping policy. It is a tax on every family that buys fuel, food, or anything that moves by water. Repeal it.
