If your business handles international shipments, understanding how to properly arrive customs bonded cargo is essential to avoid costly penalties and remain compliant with U.S. Customs and Border Protection (CBP) regulations. In this blog, we’ll break down the process, the types of bonds involved, and best practices to ensure every shipment is handled the right way from arrival to release.
📦 What is a Customs Bonded Shipment?
A customs bonded shipment is cargo that enters the U.S. but has not yet cleared customs duties or other regulatory requirements. These shipments are stored or transported under a customs bond, which ensures the government gets paid even if the importer defaults. The bond acts as insurance for the U.S. government while the goods are being processed.
✅ Step-by-Step Guide to Arriving a Bonded Shipment
Step 1: Verify Bond Type and Entry Requirements
Before arrival, ensure the correct bond is filed with CBP, and that the entry type matches the bond. For example, a T&E bond should not be used for goods destined for a bonded warehouse.
Step 2: Coordinate with the Bonded Carrier
Only CBP-authorized bonded carriers can transport bonded shipments. The carrier must ensure that the In-Bond document is filed in advance through ACE (Automated Commercial Environment).
Step 3: Submit the In-Bond Entry
The in-bond must be transmitted electronically via ACE prior to arrival:
Must include the in-bond number, origin port, destination port, and bond type.
Ensure the correct arrival port code is used.
Step 4: Arrive the In-Bond via ACE
This is where many importers make mistakes.
The carrier or authorized party must electronically arrive the in-bond through ACE when the goods reach the intended port.
Arrival must be done immediately after reaching the destination.
Failure to properly arrive a shipment can trigger CBP enforcement actions, including penalties of up to $1,000 per violation (or more in some cases).
Step 5: Update or Cancel In-Bond (if needed)
If the shipment changes route or destination, a diversion request must be submitted and approved before goods are moved elsewhere.
Use ACE to request diversion.
Avoid moving goods until CBP grants permission.
⚠️ Common Mistakes to Avoid
Late or missing in-bond arrivals: One of the most frequent errors. Always arrive shipments promptly via ACE.
Incorrect port codes: Using the wrong port code during arrival or departure can result in delays or penalties.
Unauthorized carriers: Only CBP-bonded carriers can move bonded cargo. Non-compliance can lead to shipment seizure.
Failure to file ISF: For ocean shipments, a late ISF filing may incur a $5,000 fine per shipment.
🛑 CBP Penalties for Improper Arrival
U.S. Customs has zero tolerance for non-compliance. Here are some examples of possible fines:
$1,000 per in-bond violation (19 CFR 18.8)
$5,000 per ISF violation (if late or incorrect)
Seizure or denial of future bonded movement privileges
Liquidated damages up to the full bond amount!!!!- This is usally the most popular fine for over-the-road shipments.
🔐 Best Practices to Stay Compliant
Use ACE regularly – Ensure your team is trained and has access to the ACE portal.
Partner with licensed customs brokers – They can help ensure all filings are accurate and timely.
Track in-bond shipments closely – Monitor them in real-time and verify arrivals.
Keep thorough records – Document every movement, arrival, and communication with CBP.
Conduct regular audits – Review bond usage, entry types, and arrival records to catch and correct errors early.
Properly arriving bonded shipments is not just a formality—it's a legal obligation. By understanding bond types, leveraging ACE, and maintaining accurate, timely filings, importers and carriers can stay in compliance and avoid unnecessary fines or disruptions. Remember, when in doubt, consult with your forwarding company filing company.
