Extending Limits of United States Customs Waters Act of 2025
SB 221, the “Extending Limits of United States Customs Waters Act of 2025,” would amend federal customs and anti-smuggling law to expand the geographic reach of U.S. customs waters from 12 nautical miles to 24 nautical miles from U.S. baselines, consistent with existing presidential proclamations and international law. The bill includes findings explaining that the United States already recognizes a 12-nautical-mile territorial sea and a 24-nautical-mile contiguous zone, and it states that modern vessel speed and technology justify giving enforcement agencies more time and space to interdict vessels suspected of violating U.S. law.
The bill specifically revises definitions in the Tariff Act of 1930 and the Anti-Smuggling Act so that “customs waters” would include both the territorial sea and the contiguous zone, rather than the older “four leagues” formulation. It also makes the change effective the day after enactment. In practical terms, the measure would broaden the authority of U.S. Customs and Border Protection and related enforcement officials to conduct customs, anti-smuggling, immigration, fiscal, and sanitary enforcement activities farther offshore.
The stated policy rationale is that extending customs waters to the full 24-nautical-mile contiguous zone would improve law enforcement and public health protection by allowing earlier intervention against smuggling and other maritime violations. The bill does not create a new enforcement regime so much as update statutory definitions to align with current international-law limits and existing executive proclamations.
There is little recorded controversy in the available materials. The bill was introduced by Senator Scott of Florida with bipartisan cosponsors Senators Hassan, Lankford, and Gallego, and it was referred to the Senate Committee on Finance without any recorded vote or committee transcript. That sponsorship pattern suggests at least preliminary bipartisan support, and no opposing arguments are documented in the provided record.
Because there are no hearings, amendments, or votes in the available history, the overall sentiment appears neutral to favorable, with the bill framed as a technical but operationally important law-enforcement update. The main point of discussion embedded in the text itself is the balance between expanded maritime enforcement authority and adherence to international law, but no explicit opposition is shown in the record provided.
The bill would amend section 401(j) of the Tariff Act of 1930 and section 401(c) of the Anti-Smuggling Act to redefine U.S. customs waters as extending through the territorial sea and contiguous zone, up to 24 nautical miles from U.S. baselines where permitted by international law. This would expand the statutory reach of Customs and Border Protection and related maritime enforcement authorities for customs, anti-smuggling, immigration, fiscal, and sanitary enforcement purposes, while updating outdated statutory language tied to “four leagues” from the coast.
The available record shows a generally favorable and pragmatic tone. The bill’s findings present the change as a necessary modernization to keep pace with faster vessels and evolving smuggling tactics, and the bipartisan list of sponsors suggests cross-party interest. No votes, hearings, or formal objections are included, so there is no documented opposition in the provided materials.
The principal substantive issue is the scope of U.S. maritime enforcement authority: supporters argue that extending customs waters to 24 nautical miles is needed to give law enforcement more time to intercept vessels and protect public health and revenue, while any potential critics would likely focus on whether the expansion is necessary, how it interacts with international law, and whether it could affect navigation or maritime freedoms. However, no explicit opposing testimony or recorded dissent appears in the provided context.
