This document amends the Customs and Border Protection (CBP) regulations in title 19 of the Code of Federal Regulations (19 CFR) to update provisions relating to the declaration, entry, and dutiable status of repair expenditures made abroad for certain vessels. The principal changes set forth in this document involve: conforming the regulations to statutory changes that provide an exemption from vessel repair duties for the cost of certain equipment, repair parts, and materials; and adding a provision to advise that certain free trade agreements between the United States and other countries may limit the duties due on vessel repair expenditures made in foreign countries that are parties to those agreements.
