HR 4183 United States House · 119th Congress

Federal Maritime Commission Reauthorization Act of 2025

This bill reauthorizes the Federal Maritime Commission (FMC), the agency that regulates ocean shipping in the United States, through fiscal year 2029 with increased funding from $49.2 million in 2026 to $57 million in 2029. It creates new complaint mechanisms for addressing anticompetitive practices by shipping exchanges and establishes three new advisory committees (for shippers, ports, and carriers) to provide input on ocean shipping policies. The bill also requires the FMC to develop rules for containerized freight price indexes and mandates annual reporting on foreign practices affecting ocean shipping competitiveness. These changes aim to improve oversight of the international ocean freight system while reducing regulatory duplication for industry participants.

MODERATE
The engrossed version of HR 4183 makes several substantive changes from the introduced version: it shortens the funding authorization from four years (FY2026-FY2029) to two years (FY2026-FY2027) with flat funding instead of escalating amounts, broadens the definition of controlled carriers to include those 'headquartered in' or 'significantly linked to' certain countries, narrows the priority foreign country reference to specifically the USTR priority watch list, shortens the shipping exchange registry deadline from 3 years post-2022 Act to 2 years post-enactment, and shifts the containerized freight index rulemaking focus from the indexes themselves to data acquisition, use, and protection practices.
FISCAL

Authorization of appropriations reduced from 4 fiscal years (FY2026-FY2029) with escalating amounts ($49.2M to $57M) to 2 fiscal years (FY2026-FY2027) with flat funding at $49.2M per year.

DEFINITION

The definition of controlled carrier was broadened: 'based in a country' was changed to 'based in, headquartered in, or otherwise significantly linked to a country,' potentially capturing more foreign-linked carriers.

The reference to priority foreign countries was narrowed from 'identified by the USTR in the most recent report required by section 182' to specifically 'identified by the USTR on the priority watch list included in the most recent report,' limiting it to the formal watch list rather than the broader report.

TIMELINE

The shipping exchange registry deadline was changed from 3 years after enactment of the Ocean Shipping Reform Act of 2022 to 2 years after enactment of this Act (the FMC Reauthorization Act of 2025).

REQUIREMENT

The containerized freight index rulemaking requirement was shifted from requiring an advance notice on 'price indexes for containerized ocean freight' to one on 'the manner in which data is acquired, used, and protected in developing price indexes,' refocusing the rulemaking on data governance rather than the indexes themselves.

TECHNICAL

A conforming amendment was added in Section 11(c)(2) to update references in subsection (f) of section 42506 from 'the Committee' to 'a covered Committee,' and subsequent lettered items were relettered accordingly.
