Title 19 › Chapter CHAPTER 5— - SMUGGLING › § 1701
The President can declare a part of the high seas just outside U.S. customs waters to be a customs-enforcement area when ships are hovering there and their presence is causing, helping, or threatening illegal movement of people or goods. The area can only include waters close enough that the illegal transfers could happen. It cannot go more than 100 nautical miles from the spot where the ships are hovering, and it also cannot extend more than 50 nautical miles outward from the outer edge of customs waters. The President must end the declaration once the problem is gone. Laws that apply on the high seas next to customs waters apply in this area. Customs officers may board and inspect any vessel, its cargo, and people inside the area. They can bring vessels into port and, under rules set by the Secretary of the Treasury, must pursue, seize, arrest, and enforce the applicable laws there just as they would in U.S. waters. They cannot act against a foreign vessel in ways that a treaty forbids unless a special agreement allows it. This does not remove any powers or duties the Secretary of Commerce already has.
