The US Federal Maritime Commission has proposed a $200,000 fee per voyage on Spanish-flagged vessels and import restrictions on Spanish perfumes, cosmetics, oils and fats, ceramics, stone products, sugar and confectionery — measures that would touch roughly a quarter-billion dollars of port-call costs per vessel per year if calls run weekly. Neither measure has taken effect.

The FMC announced the proposals in a statement on 14 October, following an investigation it opened in December 2024 after reports that Spanish authorities refused port access to certain vessels, including ships enrolled in the US Maritime Administration's Maritime Security Program (MSP).

The Commission said its findings confirmed that Spain denied entry to US-flagged vessels and, in its words, created unfavorable conditions for shipping in US foreign trade. It warned the restrictions could affect the efficiency and reliability of international maritime supply chains while undermining efforts to support US exports and the American merchant marine.

What does the proposal actually change?

For now, nothing is enforceable. The FMC is seeking public comments on the proposed actions, including their potential impact on shipping and international trade, before deciding whether to introduce them. Spain will also get an opportunity for a hearing before the regulator determines how to proceed.

That procedural buffer matters. Any final measures depend on the outcome of the regulatory process, and the Commission itself stresses that neither the vessel fees nor the import restrictions have taken effect. A proposal is not a tariff.

Still, the scope is unusually specific. A $200,000 levy per voyage is not a rounding error for operators — a liner service calling US ports weekly would face a theoretical $10.4 million annual exposure per vessel if the fee were applied to every call and every sailing carried the flag. Whether any Spanish-flagged liner services actually run that cadence into US ports is a question the FMC's filing does not address.

Why did the FMC open the case?

The investigation began in December 2024. Its trigger: reports that Spanish authorities refused port access to certain vessels, among them ships participating in the Maritime Security Program, the US government scheme that pays carriers to keep commercially viable vessels crewed by US mariners available for national-security missions.

The Commission's conclusion, per its 14 October statement: Spain denied entry to US-flagged vessels. The regulator frames this not merely as a bilateral friction point but as a supply-chain risk — a threat to the reliability of maritime logistics and to policy efforts behind US exports and the American merchant marine.

Who carries the commercial exposure?

If the measures survive the regulatory process, three groups feel them differently.

• Spanish-flagged operators face the direct $200,000-per-voyage fee, a cost that would either reroute services to other flags or pass through to freight rates on affected lanes.
• US importers of the listed goods — perfumes, cosmetics, oils and fats, ceramics, stone products, sugar and confectionery — confront possible import restrictions, with sourcing and landed-cost implications long before any enforcement date.
• Forwarders and shippers on transatlantic lanes should watch the comment period closely; the FMC has explicitly invited input on trade impact, which signals the outcome is genuinely open.

The caveat is as important as the headline. The FMC has proposed, not imposed. Spain gets a hearing. Public comments come first. Precedents for this kind of retaliatory port-access measure are rare, and the Commission has not published a timeline for a final decision.

What is not said in the filing is also worth noting: the FMC names no specific denied voyages, no count of affected vessels, and no Spanish ports involved. The evidentiary detail sits behind the investigation's conclusions rather than in the public statement.

The next hard signal will be the close of the comment period — and whether the FMC converts a $200,000-per-voyage proposal into enforceable policy or lets the hearing process dilute it.
