The culmination of U.S. trade policies in 2025 has introduced significant port service fees and export requirements that will reshape LNG dual-fuel vessel economics and supply chain strategies. On April 17, 2025, the Office of the United States Trade Representative finalized its Section 301 investigation actions targeting maritime, logistics and shipbuilding sectors. Under the new regime, foreign-built vessels owned or operated by China-linked entities will incur port entry fees starting at $50 per net ton per rotation from October 14, 2025, escalating to $140 by 2028, with a cap of five rotations per year. Non-Chinese operators of Chinese-built vessels face similar charges based on net tonnage or container counts, with prospects for fee remission contingent upon ordering U.S.-built vessels of equivalent tonnage.

Crucially for LNG exporters, the action mandates that a minimum percentage of U.S. liquefied natural gas exports must be carried on U.S.-built, -flagged, and -operated vessels. Beginning April 17, 2028, one percent of LNG cargoes must utilize domestic tonnage, with incremental increases culminating at 15% by April 17, 2047. Failure to meet these thresholds may result in export license restrictions, although vessel owners can suspend the export requirements for up to three years by commissioning delivery of U.S.-built LNG carriers compliant with stringent domestic build standards.

These measures will drive a reorientation of shipbuilding orders, heightened collaboration between shipowners and U.S. yards, and potential cost pass-through to energy customers. Furthermore, ancillary tariffs on ship-to-shore cranes and handling equipment ranging from 20% to 100% are poised to escalate capital expenditure for newbuilds and retrofits. As a result, companies are evaluating supply chain diversification, alliance formation with U.S. builders, and leveraging exemptions to mitigate operational disruption and preserve global trade competitiveness.
