If your cargo arrives in the U.S. before customs duties are paid, it cannot simply be picked up by any trucking company. It has to move “in-bond” — under the control of a carrier that U.S. Customs and Border Protection (CBP) has approved and bonded. In a gateway market like Miami, bonded trucking is everyday infrastructure. Here is what it means and when you need it.
Bonded carrier, defined
A bonded carrier is a transportation company that has filed a custodial bond with CBP, making it financially liable for imported merchandise that has not yet cleared customs. The bond guarantees that in-bond cargo moving between ports, airports, container freight stations, and bonded warehouses stays under customs control until duties are paid or the goods are exported. Go LTL operates as a CBP-approved bonded common carrier under code LBT4.
When does freight move in-bond?
Immediate Transportation (IT)
Cargo arrives at one port — say PortMiami — but will clear customs somewhere else, such as an inland CFS or another city. A bonded carrier moves it between those points before entry is filed.
Transportation and Exportation (T&E)
Goods pass through the U.S. on their way to another country — common in South Florida, where cargo constantly transits between Latin America, the Caribbean, and the rest of the world. The freight is never “imported,” so it must stay bonded door to door.
Airport transfers and airline recovery
Airfreight that lands at Miami International Airport (MIA) and needs to move to a bonded facility, or vice versa, travels with a bonded carrier. Because we are also TSA-approved, our drivers can handle air waybill verification and deliver directly to airline cargo facilities — see our local pickup and delivery services.
Bonded carrier vs. bonded warehouse
They are two links in the same chain. The bonded carrier moves uncleared cargo; a bonded warehouse stores it, in some cases for an extended period, without duties being due until the goods enter U.S. commerce. If you need storage between the port and final delivery, our affiliated bonded warehouse handles that leg, and cargo can also transload through a container freight station.
Why it matters in South Florida
Miami is one of the busiest international freight gateways in the country, with PortMiami, Port Everglades, and MIA all within a short drive of each other. A huge share of local cargo is imported, transshipped, or destined for re-export — exactly the freight that requires bonded handling. Using a non-bonded trucker for in-bond cargo is not a shortcut; it is a customs violation that can mean penalties, seized freight, and lost time. If you are unsure whether your shipment needs bonded transport, ask your customs broker, then talk to our team about the trucking leg.
Frequently asked questions
How do I know if my cargo needs a bonded carrier?
If duties have not been paid and the goods have not been formally entered into U.S. commerce — for example, freight moving port-to-CFS, port-to-bonded-warehouse, or transiting to another country — it must move with a bonded carrier. Your customs broker can confirm the entry type.
Is a bonded carrier the same as a TSA-approved carrier?
No. Bonding is a CBP (customs) authorization for uncleared cargo; TSA approval covers security screening requirements for air cargo. Go LTL holds both, which is why we can run airport transfers and in-bond moves with the same fleet.
Does bonded trucking cost more?
Bonded moves involve extra liability, paperwork, and compliance, so pricing differs from standard local freight. Get a quote with your entry type, pickup, and delivery points for an exact number.
