Manifest Modernization Act of 2023

This bill updates U.S. customs manifest rules to require more detailed public disclosure of cargo information while strengthening privacy protections. It mandates that publicly available manifests include the country of origin, country of last transit, and tariff classification for all cargo, and requires shipping companies to remove personal data like Social Security numbers, addresses, and passport details before disclosure. The bill also adds a new checkbox to indicate whether shipments are destined for private individuals or businesses. These changes directly affect shipping companies, customs officials, and individuals whose personal information may appear on cargo manifests.
