US maritime regulator proposes measures against Spanish-flagged vessels
The Federal Maritime Commission is considering vessel fees and import restrictions following an investigation into Spain’s port access practices.
The US Federal Maritime Commission (FMC) has proposed new measures targeting Spanish-flagged vessels and selected Spanish imports after concluding that restrictions imposed by Spain on certain US-flagged ships created unfavorable conditions for international maritime trade.
In an announcement issued on 14 October 2026, the regulator outlined proposals that include a US$200,000 fee per voyage for Spanish-flagged vessels and potential restrictions on certain goods entering the United States from Spain.
The measures have not been adopted. The FMC is seeking public comments before determining how to proceed and will offer Spain an opportunity for a hearing.
Investigation into Spanish port restrictions
The FMC launched its investigation in December 2024 following reports that Spanish authorities had denied port access to certain vessels, including ships participating in the US Maritime Administration’s Maritime Security Program.
The investigation concerned restrictions involving vessels carrying cargo associated with Israel.
According to the FMC, the evidence gathered established that Spain’s actions had prevented certain US-flagged vessels from calling at Spanish ports, requiring changes to their planned operations.
The regulator concluded that these restrictions created unfavorable conditions affecting US foreign maritime trade and raised concerns about the reliability of international shipping operations.
In submissions to the investigation, Spain maintained that its actions complied with Spanish, European Union and international legal requirements concerning defense and dual-use goods. It also argued that the matter should be addressed through diplomatic channels.
The FMC rejected those arguments as grounds for ending its investigation, maintaining that it has authority to consider measures addressing unfavorable conditions affecting US shipping.
Proposed vessel fees and import restrictions
The FMC has outlined two possible remedies. The first would introduce a US$200,000 per-voyage fee for Spanish-flagged vessels, while the second would restrict imports of selected categories of Spanish goods into the United States.
The product categories under consideration include perfumes and cosmetics, oils and fats, ceramics, articles of stone, and sugar and confectionery products.
The regulator has invited public comments on the proposed measures and their potential consequences before deciding whether to introduce restrictions.
The notice of proposed rulemaking is scheduled for publication in the Federal Register on 15 October 2026, with a public consultation period provided under the regulatory process.
No final implementation date has been established for either proposed remedy.
