This document adopts as a final rule, without change, the proposed amendments to the CBP regulations that provide that where an owner or master of a vessel documented under the laws of the United States fails to timely pay the duties determined to be due to CBP that are associated with the purchase of equipment for, or repair to, the vessel while it is outside the United States, interest will accrue on the amounts owed to CBP and that person will be liable for interest. The purpose of this document is to ensure that the CBP regulations reflect that CBP collects interest as part of its inherent revenue collection functions in situations where an owner or master of a vessel fails to pay the vessel repair duties determined to be due within 30 days of CBP issuing the bill.
