How to Comply with the Jones Act (2026 Guide)

Need to keep your ship legal and your crew safe? Follow these five steps and you’ll know exactly how to stay on the right side of the Jones Act.

Step 1: Determine if Your Vessel Is Covered by the Jones Act

First, ask yourself if the ship sails only between U.S. ports. The Jones Act applies to any vessel that moves cargo or passengers on a coastwise route , that is, from one U.S. port to another.

Check the vessel’s flag. If it flies a U.S. flag, it automatically falls under the Act. If it’s foreign‑flagged, you must verify whether a waiver is in place. In 2026 the government issued a short‑term waiver for certain energy shipments, but the default rule still demands U.S.‑built, U.S.‑flagged, and U.S.‑crewed ships.

Next, confirm the ship’s construction date. Vessels built after 1990 are usually subject to the modern safety standards tied to the Act. Older ships may qualify for historic exemptions, but you’ll need documentation.

Finally, review the vessel’s ownership. A U.S. corporation that owns the vessel triggers the Act, even if the ship is registered abroad.

Bottom line: If your vessel is U.S.‑flagged, U.S.‑built, and moves goods coastwise, it’s covered.

Step 2: Understand Cabotage and Domestic Trade Rules

Cabotage law limits who can transport goods between U.S. ports. The Jones Act is the core of that rule, requiring U.S. vessels for domestic trade.

Read the official definition on Wikipedia to see how the law distinguishes between foreign and domestic voyages.

Know the exceptions. A temporary waiver, like the one issued in March 2026 for certain energy products, suspends the requirement for a limited time. Those waivers are rare and usually tied to national‑defense needs.

Also watch for the “coastwise point” rule. Even an offshore platform counts as a domestic point until it’s fully removed, meaning any transport to or from that platform still triggers the Act.

Keep a log of every port‑to‑port movement. That log will be your evidence if a regulator asks whether a shipment was truly domestic.

Step 3: File Required Documentation and Registrations

Documentation is the backbone of compliance. Start by registering the vessel with the U.S. Coast Guard’s Vessel Documentation Center. The registration certificate proves the ship meets the Jones Act’s flag requirement.

Next, file a Statement of Intent with the Maritime Administration (MARAD). This form declares that the vessel will be used for domestic trade and outlines its compliance plan.

Don’t forget the crew list. The list must show that at least 75% of the crew are U.S. citizens or permanent residents, as required by the Act.

When an injury occurs, the paperwork becomes even more critical. BoatLaw explains that a well‑filed claim hinges on solid medical records, employer reports, and the ship’s documentation. Missing a single form can delay compensation for injured workers.

By the end of this step you should have a complete packet: registration certificate, MARAD intent statement, crew manifest, and any waivers that apply.

Step 4: Comply with Crew Nationality and Labor Standards

The Jones Act protects U.S. seamen, so you must keep the crew composition within legal limits. At least three‑quarters of the crew must be U.S. citizens, permanent residents, or lawful permanent residents.

If you employ foreign crew members, they can only fill roles that don’t fall under the Act’s protection, such as certain technical specialists on a foreign‑flagged vessel.

Labor standards also matter. The Act requires that crew receive wages comparable to those on U.S.‑flagged ships. Review the wage schedules published by the U.S. Department of Labor to avoid underpaying.

When a temporary waiver is in effect, the crew‑nationality rule still stands. The waiver only relaxes the vessel‑flag requirement, not the labor protections.

If you’re unsure, JonesActLaw’s 2026 waiver analysis notes that workers keep their rights even during a waiver period.

Step 5: Handle Exemptions, Waivers, and Enforcement

Exemptions are the safety valve of the Jones Act. The most common ones involve national‑defense needs, natural disasters, or temporary supply crises.

In March 2026 the Department of Homeland Security granted a 60‑day waiver under 46 U.S.C. § 501(a) to ease energy shortages caused by the Iran conflict. Holland & Knight explains that such waivers require a written request from the Secretary of Defense and must be reported to Congress within 24 hours.

When a waiver is active, you must still file a post‑voyage report with the Maritime Administrator within 10 days, as required by 46 U.S.C. § 501(c). The report should list the vessel name, commodity, HTS code, carrier, ports, and dates.

Enforcement is strict. CBP can inspect vessels at any port, and violations can lead to civil penalties of up to $10,000 per day per violation.

Use this table to decide whether you need a waiver or can claim an exemption:

Bottom line: Always verify the waiver’s scope, file the required post‑voyage report, and keep records for at least two years.

FAQ

Does the Jones Act apply to foreign‑flagged vessels?

No, the Jones Act only applies to vessels that are U.S.-built, U.S.-flagged, and U.S.-crewed when moving goods between U.S. ports, unless a specific waiver is in place.

Can I transport petroleum products without a waiver?

Generally no; petroleum is a covered commodity, so you need a U.S.-flagged vessel unless a temporary waiver like the 2026 energy waiver is active.

What record‑keeping is required for crew nationality?

You must maintain a crew manifest showing citizenship status for each crew member and keep it on board for the vessel’s entire voyage.

How long does a Jones Act waiver last?

Waivers are time‑limited; the 2026 waiver lasted 60 days, expiring on May 17, 2026, unless extended by the Secretary of Defense.

What penalties exist for non‑compliance?

Civil penalties can reach $10,000 per day per violation, and the vessel may be barred from U.S. ports until compliance is demonstrated.

Do I need a lawyer to file a Jones Act claim?

While you can file on your own, the process is complex; an experienced maritime attorney can help gather evidence, meet deadlines, and negotiate with insurers.
