# Puerto Rico Jones Act study warns unrestricted foreign competition could wipe out US-flag vessels

A study prepared for the Jones Act industry trade association La Alianza Maritima de Puerto Rico estimates unrestricted foreign-flag competition could eliminate most US-flag vessels in the Puerto Rico trade, while also finding foreign carriers would lose their labor cost advantage if they had to comply with US labor rules.

Unrestricted competition from foreign-flag vessels could lead to the disappearance of most US-flag vessels in the Puerto Rico trade, according to a study prepared for La Alianza Maritima de Puerto Rico, a trade association representing Jones Act ship operators and maritime unions in the Puerto Rico trade.[^5][^2] The Alianza is affiliated with the American Maritime Partnership, a main national trade association for the Jones Act industry.[^3]

The study also found that foreign carriers would lose their labor cost advantage if they must comply with US labor rules.[^5] With competition, technological and environmental improvements are implemented faster than building ships in the US that rely on 25-year financing.[^4]

The estimated total annual cost of Jones Act carrier service to Puerto Rico is $668.6 million, with total revenue estimated at $703.8 million.[^7] Downsizing Jones Act carriers to 40-foot containers would cause significant incremental costs estimated at up to $120.8 million per year in lost economies.[^6]
