A bond-to-bond transfer in U.S. customs is an in-bond movement of merchandise under CBP control from one bonded location or in-bond stage to another, rather than a normal customs clearance at the first arrival point. In practical terms, the goods stay under customs bond and customs supervision while they are moved, filed, tracked, and completed under the relevant in-bond rules. The key point is that this is not the same as final import release for U.S. consumption.
If you are trying to understand the U.S. procedure, the short answer is: the movement must be filed electronically, CBP authorisation is required before the goods can move in bond, the carrier or filer must maintain the in-bond record, and the shipment must arrive within the applicable transit window. The governing framework is found in 19 CFR Part 18 on transportation in bond and merchandise in transit and the related in-bond rules in 19 CFR 18.1.
What Is a Bond-to-Bond Transfer in Customs?
In U.S. customs language, “bond-to-bond transfer” is commonly used to describe merchandise moving under one customs bond arrangement to another bonded stage, warehouse, or conveyance under CBP in-bond procedures. The phrase is not a separate clearance category on its own; it is best understood as a customs-controlled transfer that remains within the in-bond system.
This matters because many readers use the term loosely. Sometimes they mean a transfer between bonded warehouses at the same port. Sometimes they mean an in-bond movement from an arrival port to another port of destination or exportation. And sometimes they mean a transfer from one bonded conveyance or custody point to another while the goods remain under bond. The customs procedure depends on which of those situations applies.
What it is not: it is not ordinary import entry at the border, and it is not simply a private transfer of a bond certificate from one person to another. Customs bond requirements are tied to the movement and compliance obligation, not to an informal handover.
CBP In-Bond Procedure: Filing, Authorisation, and Transit Rules
The core rule is simple: in-bond merchandise cannot move until CBP authorises the movement. Under 19 CFR Part 18, movement authorisation is required before merchandise can be transported in bond, and CBP transmits that authorisation through a CBP-approved electronic system.
That is why the process is mostly operational and documentary, not just logistical. The filer submits the in-bond movement electronically, CBP accepts and authorises it, and the merchandise is then moved under the applicable bond coverage. Once the carrier takes custody under the in-bond movement, the carrier assumes responsibility for the movement in accordance with the bond and the applicable CBP rules.
For a practical overview of how that looks in current systems, Descartes’ summary of the in-bond shipment process explains the ACE-based filing workflow and the use of entry type 61 for Immediate Transportation and 62 for Transportation and Exportation in modern practice, replacing the older paper-only approach in many cases. You can review that operational overview in the in-bond shipment guide.
What happens in the basic CBP workflow?
- The importer, broker, warehouse, or logistics provider plans the move.
- The filer submits the in-bond application electronically.
- CBP reviews and authorises the movement.
- The merchandise moves under bond to the approved destination, warehouse, or export point.
- The in-bond record is updated as required.
- The shipment is delivered within the required transit period and completed under the relevant rules.
That workflow is consistent with CBP’s in-bond framework and the post-2017 electronic filing model described in the Federal Register rulemaking on the in-bond process. See the CBP rule discussion in Changes to the In-Bond Process.
How IT Bonds and T&E Bonds Fit Into the Procedure
The search intent behind bond-to-bond transfer often overlaps with two specific bond types: Immediate Transportation (IT) and Transportation and Exportation (T&E). They are related, but they are not interchangeable.
| Bond / movement type | Typical use | Practical effect |
|---|---|---|
| IT bond | Immediate Transportation | Moves merchandise under bond from the arrival point to another CBP-approved destination in the customs territory. |
| T&E bond | Transportation and Exportation | Moves merchandise through the United States for export from another port under in-bond control. |
An IT movement is used when goods are not being entered for U.S. consumption at the first port and instead must be transported to another port or location under bond. A T&E movement is used when merchandise will continue in bond and be exported rather than consumed in the United States.
For a deeper discussion of customs bond types and how continuous coverage works across transactions, see our guide to continuous customs bond. That article is useful background, but remember that bond continuity is different from the in-bond movement itself.
In practice, the wrong bond type or insufficient coverage can delay the movement or prevent CBP from accepting the in-bond filing. A bond is not just paperwork; it is part of the authorisation and liability structure for the shipment.
Transferring Merchandise Between Bonded Warehouses
One common meaning of bond-to-bond transfer is a transfer from one bonded warehouse to another. This is especially important where merchandise remains in customs custody but needs to change storage location, operator, or operational phase before final release.
CBP rules recognise that merchandise may be transferred between bonded warehouses in certain circumstances. The cited ruling material points to transfers at the same port under the supervision of the port director, which means the transfer is not an informal warehouse handoff. It remains a regulated customs transaction.
That distinction is important because a bonded-warehouse transfer is not the same as ex-bond release. The goods are still under customs control, and the move does not itself equal final importation or duty-paid release for U.S. consumption.
In practice, local port procedures may affect how the transfer is handled, but the governing framework still comes from CBP’s in-bond rules and the relevant port-level instructions. Where warehouse activity is involved, the business should confirm the operational steps with the warehouse operator, customs broker, and port-facing CBP process before moving the cargo.
How Transfers Work at the Port of Destination or Exportation
Another important scenario is when in-bond merchandise reaches the port of destination or the port of exportation and must be transferred to another conveyance. The regulations specifically address transfer at the port of exportation, including transfer to another conveyance after arrival at the selected port.
That means the procedure is not always a simple “drop and go” warehouse movement. If the goods must be moved from one conveyance to another at the export port, the transfer must follow the applicable CBP procedures in Part 18. The exact requirements depend on the location, the movement type, and whether the shipment is being exported, diverted, or otherwise handled under in-bond control.
CBP’s rule text makes clear that transfer of bonded merchandise to another conveyance at the port of exportation follows the prescribed procedures in the relevant sections of Part 18. In other words, the customs process remains active until the transfer is complete and the in-bond obligations are satisfied.
Changing the port of destination or exportation
Sometimes the practical issue is not the final warehouse or export truck, but the port itself. The regulations also address changing the port of destination or port of exportation for an in-bond movement. In those cases, the filer must submit the required change request through the approved in-bond system rather than simply rerouting the shipment informally.
This is a good example of why in-bond movement is a controlled customs procedure. The goods cannot simply be reassigned to a new route without CBP involvement. If the destination changes, the paperwork and the electronic in-bond record must be updated accordingly.
Step-by-Step Bond-to-Bond Transfer Process and Required Documents
The best way to think about the procedure is as a sequence. It begins with planning and ends only when the in-bond movement has been completed, reported, and accepted under the applicable rules.
1. Confirm the correct movement type
First, determine whether the shipment is an IT movement, a T&E movement, a bonded-warehouse transfer, or another in-bond scenario. This matters because the filing, route, and bond responsibility depend on the exact transaction.
2. Prepare the filing data
The in-bond filing normally needs accurate shipment information, including:
- CBP Form 7512 or the equivalent in-bond filing data
- Routing information
- Carrier details
- Goods description
- HTS/HTSUS information where required for classification and control
Those are the practical data elements supported by the sources. Do not treat the filing as a vague cargo note; the system needs shipment-specific information to authorise and track the movement.
3. File the in-bond movement electronically
In modern practice, the filing is made through ACE or another CBP-approved electronic interface. The system records the in-bond movement and allows CBP to approve or deny movement authorisation.
4. Receive CBP authorisation
Nothing moves until CBP authorises it. This is the point many shippers miss. Even if the cargo is already physically at a warehouse, the shipment is not free to travel in bond until authorisation is issued.
5. Move the merchandise under bond
Once authorised, the carrier or bonded party transports the merchandise to the approved location, port, or export point under the applicable bond responsibility.
6. Report arrival and complete the movement
The shipment must then be delivered within the transit period and the in-bond record must be completed as required. The process is not finished merely because the truck or vessel departed on time.

You may also find our guide on customs POA useful where a broker or representative is involved in filing and compliance.
How Long Does an In-Bond Transfer Take?
There are two different timing questions people often mix up: how long it takes to get a customs bond, and how long the in-bond transfer has to travel. They are not the same thing.
For the in-bond movement itself, the CFR rule provides a transit window. As reflected in 19 CFR 18.1, merchandise to be transported in bond must generally be delivered to CBP at the destination or exportation port within 30 days from the relevant trigger date stated in the rule. For movements via barge for all or part of the journey, the period is 60 days. The rule’s timing starts from the date of conveyance arrival at the origination port if the application was received and approved before arrival, or from the date CBP provides movement authorisation, whichever is later.
That timing rule is important because it means the shipment is still under a deadline even after approval. If the goods are delayed, the filer and carrier need to monitor the in-bond status carefully and make sure the movement remains compliant.
By contrast, how long it takes to obtain a customs bond depends on the bond type, underwriting, and broker or surety process. That is a separate issue from in-bond transit time. If you need a practical overview of the bond side of the process, our article on continuous customs bond is a useful starting point.
How Bond-to-Bond Transfer Differs from Customs Clearance and Ex-Bond Release
It is easy to confuse in-bond movement with ordinary customs clearance, but they are different stages.
- Bond-to-bond transfer means the goods remain under customs bond and move under CBP-controlled in-bond rules.
- Customs clearance means the goods are being processed for release, entry, or admissibility in the usual import workflow.
- Ex-bond release means the goods are being removed from bonded status and released under the applicable entry or release procedure.
That distinction matters because a transfer does not automatically equal final importation. The merchandise may still need to be entered, released, exported, or otherwise completed later in the workflow. The transfer is one step in the customs chain, not necessarily the end of it.
For readers who are comparing customs release and payment handling, our guide to pay import customs duty online explains the normal duty-payment path that applies when goods are being entered rather than moved in bond.
Customs Bond Requirements, Ownership, and Common Misconceptions
One common misconception is that a customs bond can simply be transferred to another person the way ownership of goods might be transferred. That is not a safe assumption.
A customs bond is tied to the legal and operational obligation it secures. The bond requirement depends on the type of movement, the liable party, and the customs transaction. It is not the same thing as ownership of the cargo, and it is not usually something a person can casually hand over without regard to the legal structure.
In the in-bond context, the bonded carrier or responsible party takes on liability under the movement. That is why the transaction has to be filed, authorised, and completed under the CBP framework. If you are unsure whether a particular bond can be used, reassigned, or replaced, you need to confirm the bond type and the exact transaction before moving the goods.

Practical Next Steps for Importers, Brokers, and Warehouse Operators
If you are setting up a bond-to-bond transfer, the most useful next steps are operational:
- Confirm whether the movement is IT, T&E, or a bonded-warehouse transfer.
- Verify that the bond coverage is active and appropriate for the movement.
- Prepare the filing data carefully, including routing and carrier details.
- Check whether the transfer involves a port change, a conveyance change, or a warehouse-to-warehouse move.
- Coordinate with your customs broker, warehouse, and carrier before the goods are released for movement.
- Confirm any local port practice that may affect how the transfer is handled.
If your operation is unusual, do not rely on generic advice alone. Local port policy can matter in practice, but the baseline remains CBP’s in-bond framework. When in doubt, ask the broker or compliance team to confirm the exact filing type and the correct port procedure before shipment.
And remember the timing distinction: the time to obtain a customs bond is not the same as the in-bond transit deadline. A business can have a bond in place yet still fail the transfer if the filing, authorisation, or arrival timing is wrong.
In short, the customs procedure for bond-to-bond transfer is a controlled in-bond movement under CBP rules: file electronically, obtain authorisation, move under bond, update the record, and complete the movement within the required time. Once you separate in-bond movement from final customs entry, the process becomes much easier to manage.
