The U.S. Federal Maritime Commission (FMC) has confirmed it is closely monitoring the impact of the Iran conflict on ocean freight markets, particularly conditions affecting vessels transiting the Strait of Hormuz.
With the regional war disrupting supply chains across the Middle East, the regulator said it is using its statutory authority to ensure that shipping lines comply with the requirements of the Shipping Act when introducing new charges or adjusting tariffs.
The closure of the strait has trapped hundreds of vessels in the Persian Gulf and forced carriers to reroute cargo through alternative ports. In response to these disruptions, several ocean carriers have already introduced emergency surcharges designed to cover the cost of diversions and operational delays.
The FMC acknowledged that wartime conditions have historically generated significant profits for parts of the shipping sector. However, the commission said it is particularly focused on ensuring that any changes in rates or rules remain lawful and transparent.
Under FMC regulations, carriers must normally provide at least 30 days’ notice before implementing tariff changes that increase costs for shippers. The commission noted that operators can request a Special Permission (SP) to shorten this waiting period if they demonstrate valid reasons.
Such requests are reviewed and voted on by the commission. If approved, the authorization specifies the date on which the new charge may take effect.
The regulator also reminded carriers that tariff rates and charges must be in effect at the moment cargo is received.
At the same time, the commission urged shippers to carefully review their contracts and tariff structures to ensure they understand how surcharges may apply during the current disruption.
The FMC also reiterated that the Shipping Act prohibits discriminatory or unreasonable practices by carriers, a reminder that regulatory oversight remains active even during periods of geopolitical crisis.
