Jones Act requirements have resulted in a discrete shipping market between Puerto Rico and the United States. Most of the cargo shipped between the United States and Puerto Rico is carried by four Jones Act carriers that provide dedicated, scheduled weekly service using containerships and container barges.he effects of modifying the application of the Jones Act for Puerto Rico are highly uncertain, and various trade-offs could materialize depending on how the Act is modified. Under a full exemption from the Act, the rules and requirements that would apply to all carriers would need to be determined.
