The Congress, the legislature of the federal government of the United States of America, passed on 13 June 2022 the Ocean Shipping Reform Act. This bill revises requirements governing ocean shipping to increase the authority of the Federal Maritime Commission (FMC) to promote the growth and development of U.S. exports through an ocean transportation system that is competitive, efficient, and economical. For example, the bill requires the FMC to (1) investigate complaints about detention and demurrage charges (i.e., late fees) charged by common ocean carriers, (2) determine whether those charges are reasonable, and (3) order refunds for unreasonable charges. It also prohibits common ocean carriers, marine terminal operators, or ocean transportation intermediaries from unreasonably refusing cargo space when available or resorting to other unfair or unjustly discriminatory methods. See the text (reference S.3580) as approved by the U.S. Congress.
