More than 80% of Puerto Rico's containerised cargo moves through San Juan (PR SJU), which handled roughly 1.09 million TEU and over 11 million short tons in 2021. The harbour splits into three areas — Puerta de Tierra, Isla Grande and Puerto Nuevo — with Puerto Nuevo forming the container core, where Puerto Nuevo Terminals, a joint venture of Luis Ayala Colón and Puerto Rico Terminals, operates alongside TOTE Maritime, while Crowley works its own berth at Isla Grande. Container berths offer roughly 12 to 13 metres alongside and process on the order of 1,000 truck moves per day at peak. San Juan is US customs territory, so mainland trade counts as domestic cargo, but the Jones Act requires US-flag, US-built vessels on those lanes and shapes freight rates accordingly, while international shipments clear US Customs and Border Protection. The US federal government has committed a total of USD 109 million to reconstruct and modernise key port facilities, including USD 25 million released in February 2026 specifically for upgrades at Puerto Nuevo terminals and Pier 15 in Isla Grande, alongside the USD 42 million capacity expansion announced in April 2025. Inland distribution depends entirely on the island's road network, since there is no freight rail, and San Juan doubles as a major Caribbean cruise homeport. For pure transshipment, Caucedo in the Dominican Republic and Kingston in Jamaica compete regionally, while Ponce is the main alternative within Puerto Rico.
