A customs bond is a financial guarantee required by US Customs and Border Protection (CBP) to ensure that import duties, taxes, and fees are paid and that all customs regulations are followed. If you are involved in importing goods into the United States — whether as the importer of record, a customs broker, or a carrier in certain situations — you need to understand how customs bonds work and which type is right for your operation.
This guide covers the two types of customs bonds, when trucking companies specifically need them, how much they cost, and how to obtain one.
What Is a Customs Bond?
A customs bond is a contract between three parties:
- The principal — the importer, broker, or carrier who has obligations to CBP
- The surety — an insurance company or surety company that guarantees the principal's obligations
- CBP — the government agency that requires the bond and can make claims against it
The bond guarantees that the principal will:
- Pay all duties, taxes, and fees owed to CBP
- Comply with all US customs laws and regulations
- Fulfill all entry requirements for imported goods
If the principal fails to meet these obligations, CBP can make a claim against the bond for up to its full value. The surety pays the claim and then seeks reimbursement from the principal.
Who Needs a Customs Bond?
Importers
Any person or company importing goods into the United States with a commercial value of $2,500 or more must have a customs bond. This is the most common use case. The bond is filed by the importer of record (or their customs broker) and covers duties, taxes, and compliance obligations.
Carriers
Trucking companies generally do not need their own customs bond for standard cross-border freight movements — the importer of record provides the bond that covers the goods being transported. However, carriers need a customs bond in specific situations:
- When acting as the importer of record — if you are importing goods on your own behalf (not hauling someone else's freight), you need a bond
- International carriers — foreign carriers operating in the US may need a carrier bond (known as a custodial bond or activity code 3 bond) for bonded carrier privileges
- In-transit/bonded freight — carriers transporting goods under bond (in-transit shipments that haven't cleared customs yet) may need a carrier bond
- Foreign Trade Zone (FTZ) operations — carriers moving goods into or out of FTZs may have bond requirements
For most Canadian carriers hauling freight into the US on behalf of a shipper, the shipper's customs broker handles the bond. But if your operation involves any of the situations above, you need your own bond.
Single Entry Bond vs Continuous Bond
Single Entry Bond
A single entry bond covers one specific import transaction. It is purchased for each individual shipment crossing the border.
Cost: Typically $50-$100+ per entry, depending on the value of the goods and the surety provider. For high-value shipments, the bond premium can be higher.
Bond amount: The bond face value must equal the value of the goods plus any estimated duties and taxes. CBP requires a minimum bond amount of $100.
Best for: Importers who bring goods into the US infrequently — a few times per year. If you cross the border regularly with commercial goods, single entry bonds become expensive quickly.
Continuous Bond
A continuous bond covers all import transactions for a 12-month period. One bond covers unlimited entries during the bond year.
Cost: Typically $200-$1,000+ per year in premium, depending on the bond amount, the importer's financial strength, and the surety provider. Larger importers with higher bond amounts pay more.
Bond amount: For importers, CBP typically requires the bond amount to be 10% of the total duties, taxes, and fees paid in the prior year, with a minimum of $50,000. For carriers with custodial bonds, the amount is based on the estimated value of goods transported under bond.
Best for: Anyone importing into the US more than a few times per year. The continuous bond pays for itself after just 3-5 single entry bond purchases.
Cost Comparison Example
| Scenario | Single Entry | Continuous |
|---|---|---|
| 4 crossings per year | $200-$400 total | $300-$500/year |
| 12 crossings per year | $600-$1,200 total | $300-$500/year |
| 50+ crossings per year | $2,500-$5,000+ total | $300-$500/year |
For carriers crossing the border regularly, the continuous bond is dramatically more cost-effective.
How to Obtain a Customs Bond
Step 1: Determine the Bond Type and Amount
Decide whether you need a single entry or continuous bond based on your crossing frequency. For continuous bonds, calculate the required bond amount:
- Importers: 10% of estimated annual duties/taxes (minimum $50,000)
- Carriers (custodial bond): Based on estimated value of bonded cargo transported
Step 2: Choose a Surety Provider
Customs bonds must be issued by a surety company authorized by the US Treasury Department. You can obtain a bond through:
- A licensed customs broker — most brokers offer bond services as part of their cross-border package. This is the easiest route for most trucking companies.
- A surety company directly — Roanoke Trade, Avalon Risk Management, and other surety companies specialize in customs bonds.
- Insurance brokers — some commercial insurance brokers offer customs bonds.
Step 3: Complete the Application
The surety will require:
- Business information (legal name, address, EIN)
- Financial statements (for larger bond amounts)
- Business credit information
- Import history or projected import volume
- Description of goods imported
Step 4: Pay the Premium
Bond premiums are typically paid annually for continuous bonds or per-transaction for single entry bonds. Most surety companies require payment before issuing the bond.
Step 5: File with CBP
The surety files the bond with CBP electronically through ACE. For continuous bonds, the bond takes effect on the date it is filed and remains active for 12 months. Renewal is annual.
Bond Sufficiency
CBP monitors whether your bond amount is sufficient to cover your import obligations. If your import volume or duty payments increase significantly, CBP may issue a bond insufficiency notice requiring you to increase your bond amount within a specified period (usually 30 days).
Factors that trigger a bond sufficiency review:
- Significant increase in import volume
- Increase in duty rates for your commodity types
- Outstanding penalties or claims against your current bond
- Changes in anti-dumping or countervailing duty rates for your products
If you receive a bond insufficiency notice and fail to increase your bond, CBP can suspend your import privileges until the bond is corrected.
What Happens If Your Bond Is Cancelled or Insufficient?
- Bond cancellation: If your surety cancels your bond (due to non-payment of premium or excessive claims), you cannot import goods until a new bond is in place. There is a 30-day notice period before cancellation takes effect.
- Bond insufficiency: CBP can deny entry of your shipments until the bond is increased to the required amount.
- Claims against the bond: If CBP makes a claim (for unpaid duties, penalties, or liquidated damages), the surety pays the claim and then seeks reimbursement from you. Excessive claims can make it difficult to obtain a new bond.
Relationship to ACE and eManifest
Your customs bond and ACE eManifest filing work together in the import process:
- The customs broker files the entry and ensures a bond is in place
- The carrier files the ACE eManifest with shipment details and PAPS numbers
- CBP matches the manifest data against the customs entry and bond
- If everything checks out, the shipment is released at the border
Without a valid bond associated with the entry, CBP will not release the goods — even if the eManifest is correctly filed.
Canadian Carriers Entering the US
Canadian carriers hauling commercial freight into the US should understand:
- The importer's bond covers most standard freight movements — you do not need your own bond as the carrier unless you are acting as the importer of record
- If you transport in-bond shipments (goods moving to an inland port of entry or bonded warehouse before clearing customs), you may need a carrier custodial bond
- Ensure your customs broker has confirmed that a valid bond is in place for every shipment before you approach the border
- Work closely with your customs broker and refer to the cross-border requirements guide for the complete documentation checklist
Key Takeaways
Customs bonds are the financial backbone of US import compliance. Most trucking companies rely on the shipper's bond for standard freight movements, but carriers who act as importers or transport bonded freight need their own. Choose a continuous bond if you cross the border more than a few times per year — the cost savings are significant.
Work with a licensed customs broker or authorized surety company to obtain and maintain your bond. Monitor your bond sufficiency, renew on time, and ensure a valid bond is in place for every shipment before heading to the border.
