CBP Just Doubled Its Reach Off Miami's Coast — What the New Customs-Enforcement Area Means for Importers

If you move freight in or out of South Florida by water — not just through PortMiami's container terminals, but via feeder vessels, project cargo, breakbulk, or smaller craft serving the Bahamas and Caribbean — U.S. Customs and Border Protection just extended how far offshore its agents can legally stop and search a boat. On August 25, 2026, CBP published a decision in the Federal Register (CBP Dec. No. 26-17, 91 FR 54800) establishing four new Customs-Enforcement Areas (CEAs), one of which runs along the entire South Florida coastline, including the Florida Keys.

What Happened

Using authority under the Anti-Smuggling Act of 1935 (19 U.S.C. 1701), CBP Commissioner Rodney Scott declared four areas of high-seas water adjacent to the U.S. coast — South Florida, Southern California, Puerto Rico, and the Gulf Coast of Texas — as Customs-Enforcement Areas. Inside a CEA, CBP officers and agents can board, examine, and search any vessel, cargo, or person, and pursue, seize, or arrest as needed, out to 24 nautical miles from the coast instead of the standard 12-mile limit. That 24-mile line matches the U.S. contiguous zone established back in 1999, so CBP isn't claiming new territory — it's using an existing legal tool (last invoked decades ago, per CBP's own filing) to apply full customs enforcement authority across a wider stretch of water it already asserts jurisdiction over for other purposes.

CBP's own numbers, cited in the Federal Register notice, explain the timing: in South Florida alone, Air and Marine Operations seized nearly 77,000 pounds of narcotics and made 26,000 apprehensions over the past five years using hovering vessels — boats that idle just outside the old 12-mile line, transfer cargo to smaller runners, and slip toward shore without lights. In a same-day press release, Commissioner Scott put it bluntly: “The ocean is not a safe haven for cartels and smugglers... If you are moving drugs, contraband, or people toward our shores, expect us to find you.” The move ties into the broader DOJ-DHS trade enforcement push we've tracked since Executive Order 14411 took effect.

What It Means for Importers

This is not a tariff change and adds no new form, license, or filing requirement. But it does raise the practical stakes for anyone whose supply chain touches South Florida coastal waters outside the main deep-water channels into PortMiami, Port Everglades, or the Miami River — think smaller vessels on Bahamas and Caribbean feeder routes, yacht and boat transport, fishing-industry imports, or breakbulk cargo transiting closer to shore than a typical container ship's approach lane.

Two things matter most in practice. First, a boarding under CEA authority means a full search of the vessel, cargo, manifest, and crew — not just a paperwork review. If your bills of lading or cargo declarations aren't airtight and consistent with what's physically aboard, a routine stop can turn into a multi-day detention. Second, this confirms CBP's 2026 enforcement posture is expanding, not easing — consistent with the broker-side due-diligence tightening we covered in late August. Importers who treat compliance as a formality, rather than a discipline, are the ones most likely to get caught up in an enforcement action that has nothing to do with their actual cargo.

Practical Next Steps

• If you charter or contract vessels operating in South Florida coastal waters — not standard containerized ocean freight — confirm manifests and cargo documentation are complete before departure, not after a boarding request.
• Brief captains and crew on standard CBP boarding procedures under 19 U.S.C. 1701 so a legitimate stop doesn't escalate through confusion or delayed paperwork.

Frequently Asked Questions

Does the new Customs-Enforcement Area apply to container ships arriving at PortMiami?

Standard container vessels arriving through established shipping channels to PortMiami were already fully subject to CBP jurisdiction at the port and within U.S. customs waters; the CEA mainly extends CBP's boarding and search authority further offshore, from 12 to 24 nautical miles, primarily affecting vessels operating outside those main channels.

What is the difference between the 12-mile customs waters limit and the new 24-mile Customs-Enforcement Area?

Before August 25, 2026, CBP's general enforcement authority extended 12 nautical miles from the U.S. coastline; the new South Florida CEA extends that authority to 24 nautical miles, matching the U.S. contiguous zone established in 1999, specifically to counter hovering vessels used for at-sea smuggling transfers.

Do importers need to file any new paperwork because of this CBP decision?

No; CBP Dec. No. 26-17 (91 FR 54800) creates no new permitting, reporting, or filing requirements for vessels, cargo, or importers — it expands the geographic area in which CBP can lawfully board, search, and seize vessels under existing authority in 19 U.S.C. 1701.

Which other areas besides South Florida got a new Customs-Enforcement Area on August 25, 2026?

CBP simultaneously designated CEAs covering Southern California, Puerto Rico, and the Gulf Coast of Texas, all effective August 25, 2026, alongside the South Florida designation.
