U.S. doubles offshore customs reach to 24 nautical miles

What it does

This bill extends U.S. customs enforcement authority from 12 nautical miles to 24 nautical miles offshore by amending the Tariff Act of 1930 and the Anti-Smuggling Act to include the U.S. contiguous zone (in addition to the territorial sea). U.S. Customs and Border Protection would gain authority to inspect, search, and seize vessels and cargo in a wider band of ocean, consistent with international law and existing presidential proclamations. The practical effect is that smugglers, illegal importers, and vessels attempting to evade U.S. law would face enforcement risk twice as far from shore.

Why we flagged it

The bill's sole operative function is to extend U.S. customs and anti-smuggling enforcement jurisdiction from 12 to 24 nautical miles offshore, consistent with international law and existing presidential proclamations. It is a straightforward jurisdictional expansion for law enforcement.

What the text implies

• Enforcement authority now extends into the contiguous zone, where U.S. law applies to foreign vessels engaged in smuggling or customs violations, but the bill does not explicitly address how disputes with foreign governments over enforcement in that zone will be handled.
• The bill references Presidential Proclamations 5928 (1988) and 7219 (1999) as the legal basis for the 24 nm limit; if either proclamation is later challenged or modified, the statutory authority granted here may become misaligned with actual U.S. maritime claims.
