# Puerto Rico labor deal could set precedent for shipbuilding, steel industries

Experts warn the agreement may force smaller companies to face unsustainable labor costs if the pattern spreads to other industries.

A labor agreement in Puerto Rico's maritime sector could set a precedent for other U.S. industries including shipbuilding and steel, potentially forcing smaller companies to face unsustainable labor costs, experts warn.[^1]

The warning comes amid longstanding criticism of the Jones Act, which restricts domestic waterborne cargo to U.S.-built, U.S.-flagged, U.S.-crewed vessels. Critics say the law makes U.S. shipbuilding and shipping industries highly protected and uncompetitive.[^2] Jones Act ships cost about three times foreign levels to build and at least twice as much to operate.[^3]

The read here is that any labor cost increase in a protected trade like Puerto Rico's could compound the existing cost gap. One study found that unrestricted competition from foreign-flag vessels could eliminate most U.S.-flag vessels in the Puerto Rico trade, though foreign carriers would lose their labor cost advantage if they had to comply with U.S. labor rules.[^7] The report's findings could also affect other noncontiguous domestic trades including Alaska, Guam and Hawaii.[^5]
