How to Verify a U.S. Customs Bond (CBP Bond): A Practical Guide for Importers
Avoid Customs Delays, Bond Insufficiency Notices, and Unexpected Clearance Issues
For companies importing goods into the United States, having a valid U.S. Customs Bond (CBP Bond) is not simply a compliance requirement—it is essential for ensuring smooth customs clearance.
Understanding how to verify your bond before shipment can help you avoid costly storage charges, customs delays, and disruptions to your supply chain.
This guide explains what a Customs Bond is, why it matters, and the most effective ways to verify its status.
What Is a U.S. Customs Bond?
A Customs Bond, also known as a CBP Bond or Surety Bond, is a legally binding agreement among three parties:
- Principal: The importer
- Surety: An insurance or surety company
- Beneficiary: U.S. Customs and Border Protection (CBP)
The bond guarantees that the importer will:
- Pay all applicable customs duties, taxes, and fees
- Comply with U.S. customs laws and regulations
- Fulfill any financial obligations arising from import transactions
According to CBP regulations, commercial imports valued at more than USD 2,500 generally require a Customs Bond, including many duty-free shipments.
Types of U.S. Customs Bonds
| Bond Type | Best For | Coverage |
|---|---|---|
| Continuous Bond (Activity Code C1) | Frequent importers | Covers unlimited entries for 12 months nationwide |
| Single Entry Bond (SEB) | One-time or occasional shipments | Covers only one customs entry |
| International Carrier Bond | Ocean, air, rail and truck carriers | Required for transportation operators |
| Custodian / FTZ Bond | Bonded warehouses & Foreign Trade Zones | Warehouse and FTZ operations |
For Continuous Bonds, CBP generally requires the bond amount to equal 10% of the importer’s annual duties, taxes, and fees, subject to a minimum liability of USD 50,000.
Why Verifying Your Customs Bond Is Critical
Many importers mistakenly assume that once a Continuous Bond is issued, it never needs attention.
In reality, a bond may become invalid due to:
- Non-payment of annual surety premiums
- Bond termination by the surety company
- Bond amount becoming insufficient because import volume has increased
- Administrative issues with importer identification numbers
If a bond is no longer acceptable, CBP may:
- Hold or refuse cargo release
- Reject Entry Summary filings
- Reject ISF (Importer Security Filing)
- Mark the bond as Insufficient
- Suspend future imports under the same EIN
- Generate costly storage, demurrage, and detention charges
- Issue customs penalties or additional compliance actions
Because Continuous Bonds do not have a fixed expiration date, importers should verify their status regularly instead of assuming they remain active indefinitely.
4 Ways to Verify Your CBP Bond
1. Check Through the ACE Portal (Recommended)
The Automated Commercial Environment (ACE) is CBP’s official trade portal and the most reliable source for bond verification.
After obtaining an ACE account, importers can view:
- Bond Number
- Surety Company
- Bond Amount
- Effective Date
- Bond Status
- Liability Amount
ACE also provides the REV-001 Revenue Report, allowing importers to monitor whether their Continuous Bond is considered Sufficient or Insufficient by CBP.
We recommend reviewing this report monthly, especially if your import volume is increasing.
2. Ask Your Licensed Customs Broker
Licensed Customs Brokers have direct access to CBP through the Automated Broker Interface (ABI).
Using your:
- EIN
- Importer Number
- Bond Number
they can immediately verify:
- Bond Number
- Activity Code
- Bond Type
- Liability Amount
- Surety Information
- Effective Date
- Termination Date (if applicable)
- Current Bond Status
This is often the fastest option before filing an entry.
3. Contact Your Surety Company or Bond Agent
Your surety provider can confirm information that CBP does not display, including:
- Premium payment status
- Renewal dates
- Bond documents
- Bond increase requests
- Pending cancellation notices
Remember that although a Continuous Bond has no official expiration date at CBP, surety premiums are typically billed annually.
If premiums remain unpaid, the surety may issue a termination notice to CBP. Once CBP processes that notice, the bond may become inactive.
4. Contact CBP Directly
If additional clarification is required, importers may contact:
- ACE Help Desk
- CBP Revenue Division
- CBP Bond Support
When contacting CBP, prepare:
- EIN or Importer Number
- Bond Number (if available)
- Surety Company information
Understanding Common Bond Statuses
After performing a bond inquiry, you’ll typically encounter one of the following statuses.
Active
The bond is valid and currently accepted by CBP.
Insufficient
The bond liability is no longer adequate for the importer’s annual customs obligations.
This is one of the most common reasons for customs clearance delays.
Suspended
The bond has temporarily lost its effectiveness pending corrective action.
Terminated
The bond has been cancelled and no longer covers new import entries.
Important Bond Information Fields
A standard bond inquiry typically includes:
| Field | Description |
| Bond Number | Unique identification number |
| Bond Type | Continuous or Single Entry |
| Activity Code | C1, C2, C3, etc. |
| Liability Amount | Maximum bond coverage |
| Effective Date | Date the bond became active |
| Termination Date | Displayed only if cancelled |
| Bond Status | Active, Suspended, Terminated, or Insufficient |
| Surety Company | Bond issuer |
For Continuous Bonds, it is perfectly normal for the Termination Date to remain blank until the bond is officially cancelled.
Frequently Asked Questions
Why did CBP reject my shipment even though my bond is active?
The most common reason is Bond Insufficiency.
As duties and tariffs increase, your annual customs liability may exceed the bond amount originally approved.
When this occurs, CBP may issue an Insufficiency Notice, requiring the importer to increase the bond amount within a specified timeframe.
I recently purchased a bond. Why can’t CBP find it?
Possible reasons include:
- The surety has not yet transmitted the bond electronically to CBP.
- Incorrect EIN or Importer Number.
- Administrative processing delays.
- Premium payment issues.
Most electronic bonds become visible within approximately 24 hours after successful submission.
Does a terminated bond still cover previous imports?
Yes.
Termination only affects future customs entries.
Outstanding duties, penalties, and liabilities arising before termination remain covered under the bond.
When should I increase my Continuous Bond?
A practical guideline is to review your bond whenever your annual customs duties, taxes, and fees approach the level supported by your current liability amount.
Importers experiencing rapid business growth or higher tariff exposure should proactively consult their customs broker or surety provider before CBP issues an insufficiency notice.
Can Customs Bonds Be Verified Through Third-Party Platforms?
Yes—but it’s important to understand where the information comes from.
There is no independent public database for Customs Bonds. All legitimate third-party platforms retrieve bond information directly from CBP through authorized interfaces such as the Automated Broker Interface (ABI) or ACE.
Common service providers include:
- Customs brokerage software
- Global trade management platforms
- Surety company customer portals
- Digital freight forwarding platforms
- Large third-party logistics (3PL) providers
These tools often provide additional features such as:
- Bond monitoring
- Renewal reminders
- Premium payment tracking
- Bond increase requests
- Compliance dashboards
However, bond information is protected commercial data. Only the importer, an authorized customs broker, or the surety company may legally access it.
Best Practices for Importers
To minimize customs risks, we recommend the following routine:
- Verify your Customs Bond before every shipment.
- Review bond sufficiency monthly through ACE or your customs broker.
- Confirm annual premium payments with your surety provider.
- Reassess bond coverage whenever import volume or duty exposure increases.
- Respond promptly to any CBP Bond Insufficiency Notice.
A proactive bond review can prevent costly delays and keep your supply chain moving smoothly.
