Manifest Modernization Act of 2025

This bill proposes to amend the Tariff Act of 1930 to significantly expand the public disclosure requirements for manifest information. It extends these requirements, previously focused on vessels, to explicitly include vehicles and aircraft arriving in the United States, thereby increasing transparency across various modes of international transport. Key changes specify that publicly available manifest information must now incorporate each subheading of the Harmonized Tariff Schedule of the United States under which cargo is classified. Furthermore, the disclosed information will explicitly include both the country of origin of the cargo and the last country through which the cargo was transported by the vessel, vehicle, or aircraft. The bill also defines "aircraft" for the purposes of the Tariff Act, with these amendments taking effect 30 days after enactment.
