Shippers who move containers to Puerto Rico out of South Florida keep running into the same surprise: it looks like an export, it prices like an export, but legally it isn’t one. Puerto Rico is inside the U.S. customs territory. That single fact changes the paperwork, the carrier options, and the shape of the ground leg — usually in your favor, occasionally not.
What the Jones Act actually requires
The Merchant Marine Act of 1920 — the Jones Act, at 46 U.S.C. 55102 — requires that merchandise transported by water between two points in the United States move on a vessel that is U.S.-built, U.S.-flagged, U.S.-owned, and crewed by U.S. citizens or permanent residents. Puerto Rico is a U.S. point for this purpose, so mainland-to-Puerto-Rico container moves fall under it.
Two practical consequences follow, and they’re the ones that matter to a shipper:
- Your carrier options are a short list. The Puerto Rico container trade is served by a small number of Jones Act carriers running scheduled service on fixed weekly rotations. You are not shopping thirty ocean carriers the way you would on a transpacific lane.
- The sailing schedule is rigid and the cutoff is real. Fixed weekly rotations with limited vessel capacity mean a missed cutoff is not a two-hour problem, it’s a seven-day problem. This is the operational fact that should drive how you plan the drayage.
Worth noting: the Jones Act does not apply to cargo moving between Puerto Rico and foreign countries. Foreign-flag vessels serve that trade freely. The restriction is specifically on the domestic leg.
“Domestic offshore” is the term to use
The trade lane you’re in is called domestic offshore — U.S. mainland to Puerto Rico, the U.S. Virgin Islands, Hawaii, Alaska, and Guam. It sits in an odd middle space: it behaves like ocean freight but it is legally domestic transportation.
No CBP entry, but not no paperwork
Because Puerto Rico is within the U.S. customs territory, merchandise moving from the mainland does not require a CBP import entry, and you are generally not filing an Electronic Export Information record the way you would for a true export. What you do have is Puerto Rico’s own tax regime — the Commonwealth administers sales and use tax and excise taxes through its Department of Treasury (Hacienda), and consignees have filing and payment obligations on arriving merchandise. Confirm the current requirements with your consignee, your broker, or the carrier before you ship. That is a tax question, not a drayage question, but it stops containers when it goes wrong.
Cargo moving the other way
Puerto Rico to mainland containers are also domestic, with the same Jones Act vessel requirement. USDA agricultural inspection applies to certain commodities leaving the island, which can add a step on the origin side that shows up as a delay on your delivery date in Florida.
How the drayage leg differs from a foreign import
Most drayage content assumes an import: vessel arrives, container discharges, customs releases, you pull it before the last free day. A Puerto Rico move out of South Florida is usually the mirror image — an export-style dray where you are delivering a loaded box to the terminal before a cutoff.
That inverts the risk:
- The clock runs before the vessel, not after. On an import, your enemy is demurrage after discharge. On an outbound domestic offshore move, your enemy is the cargo cutoff. Miss it and the freight sits a week.
- You control the loading, which means you own the errors. Weight distribution, blocking and bracing, seal application, and placarding on anything hazardous are yours. A rejected box at the gate is your problem and your week.
- Equipment sourcing works differently. You’re pulling an empty from the carrier, stuffing it, and returning it loaded, which is a three-leg move, not a one-leg move. Each leg is an appointment.
- Street turns can be available. If an inbound container from the same carrier is coming empty at the right moment, a street turn saves a trip. Worth asking about on every booking.
All of that is ordinary container drayage work, but the sequencing and the deadline discipline are different enough that it’s worth telling your carrier explicitly that the move is domestic offshore with a hard cutoff.
Where the yard earns its keep on this lane
The weekly-sailing structure creates a timing problem: cargo is ready when it’s ready, and the vessel sails when it sails. If your freight finishes production on a Wednesday and the cutoff was Tuesday, you need somewhere to put a loaded container for six days that isn’t the terminal.
Our 5-acre secured Miami yard handles that, with 24/7 access and room for 450-plus containers and trailers. Having a staging point also lets you stuff early, verify the load, and deliver into the gate at the least congested hour of the cutoff day instead of the busiest.
Heavy, oversized, and project cargo to the island
Construction equipment, generators, transformers, and machinery move heavily on this lane, and out-of-gauge or overweight pieces need to be handled correctly on the ground before they ever see a vessel. We run flatbeds and transloading equipment with forklifts rated at 19,000 and 40,000 pounds, and handle heavy hauling and out-of-gauge cargo alongside standard 20-, 40-, and 45-foot containers.
One Florida-specific caution: overweight and oversize moves are constrained by permitted routing, and the corridors around PortMiami and Port Everglades have real restrictions. Plan the route before you plan the load — our notes on Miami-Dade truck routes for port drayage cover the practical limits.
Plan the cutoff, not the sailing
The shippers who do well on the Puerto Rico lane treat the cargo cutoff as the real deadline and work backwards from it — empty pull, stuff, verify, stage, deliver — with a day of slack somewhere in the middle. Tell us the carrier, the terminal, and the cutoff, and we’ll build the schedule around it. Request a drayage quote or reach the Miami team through our contact page. Published starting rates are $500 at PortMiami and $450 at Port Everglades; actual pricing depends on the move.
Frequently asked questions
Do I need a customs entry to ship a container from Florida to Puerto Rico?
No. Puerto Rico is within the U.S. customs territory, so merchandise moving from the mainland does not require a CBP import entry and is not treated as a foreign export. You do have Puerto Rico tax obligations, since the Commonwealth administers its own sales and use tax and excise taxes through its Department of Treasury, and the consignee generally has filing and payment duties on arriving merchandise. Confirm current requirements with your consignee, broker, or carrier before shipping.
Why are there so few carriers serving the Puerto Rico container trade?
The Jones Act requires that merchandise moving by water between two U.S. points travel on a vessel that is U.S.-built, U.S.-flagged, U.S.-owned, and crewed by U.S. citizens or permanent residents. Puerto Rico counts as a U.S. point, so the trade is served by a small group of qualifying carriers running scheduled weekly service. The restriction does not apply to cargo moving between Puerto Rico and foreign countries, which foreign-flag vessels serve.
How is drayage for a Puerto Rico shipment different from an import move?
An import dray races a demurrage clock that starts after discharge. A Puerto Rico shipment out of South Florida is usually an outbound move racing a cargo cutoff before the vessel sails, and because sailings are weekly, missing the cutoff costs a full week rather than a few hours. It is also a three-leg move: pull the empty, stuff it, and return it loaded, with an appointment attached to each leg.
