Maritime Administration: Actions Needed to Enhance Cargo Preference Oversight, Report to Congressional Committees [open pdf - 2MB]
From the Highlights: "Cargo preference requirements are intended to support the U.S.-flag shipping industry. The requirements are designed to ensure the industry, among other things, has sufficient vessels and trained mariners to supplement the cargo-carrying capacity of military ships during times of war or national emergency. The William M. (Mac) Thornberry National Defense Authorization Act for Fiscal Year 2021 included a provision for GAO [Government Accountability Office] to review federal agencies' actions to monitor compliance with cargo preference requirements and to review MARAD's [Maritime Administration] enforcement activities. This report examines: (1) the extent to which MARAD has monitored and reported on agencies' compliance with cargo preference requirements and (2) MARAD's efforts to enforce cargo preference requirements, among other objectives."
