US Customs Bond: What It Is, Who Needs One, and Continuous vs Single-Entry

What a Customs Bond Is

A customs bond is a contract between three parties: the importer (principal), a surety company (the bond provider), and US Customs and Border Protection (the obligee). The bond is a financial guarantee that the importer will comply with all customs laws and pay all duties, taxes, and fees owed to the US government.

If the importer fails to pay duties, violates customs regulations, or defaults on any obligation to CBP, the surety company is required to pay CBP up to the bond amount. The surety then seeks reimbursement from the importer.

In practical terms: a customs bond protects the US government, not the importer. It is CBP's assurance that it will be paid even if the importer defaults. The importer pays a premium to the surety for this guarantee.

The bond requirement applies to:

• All formal entry imports (valued at $2,500 or more, or regulated by a government agency regardless of value).
• Imports subject to other agency regulations (FDA, CPSC, USDA, EPA, FWS) often require a bond regardless of value.
• Temporary imports under bond (TIB), carnets, and in-bond movements.
• Any shipment using an Importer Security Filing (ISF) -- the bond must be on file before the ISF is submitted, typically 24 hours before vessel loading at the origin port.

Single-Entry Bond vs Continuous Bond

There are two types of customs bonds for importers. Choosing the right one depends primarily on how frequently you import.

Single-entry bond (SEB):

• Covers one shipment only.
• Bond amount must be set at the greater of $100 or 10% of the total duties, taxes, and fees for that specific shipment. For a shipment with $5,000 in estimated duties, the single-entry bond amount would be $500.
• Cost: typically $50 to $150 per shipment from a customs broker. For small, infrequent shipments the cost per entry is low, but it adds up quickly for regular importers.
• Use case: importers who bring in one or two shipments per year, or importers testing a new product category before committing to a regular import program.

Continuous bond (also called an annual bond):

• Covers all entries at all US ports for a 12-month period, automatically renewing each year.
• Minimum bond amount set by CBP: $50,000 for most importers. Higher bond amounts are required if your annual duty liability exceeds certain thresholds -- CBP calculates the required amount as approximately 10% of the prior year's total duties, taxes, and fees, with a minimum of $50,000.
• Cost: typically $300 to $500 per year for a $50,000 bond from a surety or customs broker. The annual premium is a percentage of the bond amount, usually 0.3% to 0.5%.
• Use case: any importer bringing in three or more shipments per year. The math favors continuous bond over single-entry almost immediately for regular importers.

The break-even point: if single-entry bonds cost $75 each and a continuous bond costs $375 per year, you reach break-even at five shipments. Most importers who are serious about their business should have a continuous bond from the start.

How to Get a Customs Bond

Customs bonds are issued by surety companies licensed by the US Department of the Treasury. You do not work with the surety company directly in most cases -- bonds are purchased through a licensed customs broker or a specialized bond provider.

• Through your customs broker: The most common approach. Your customs broker can arrange both single-entry and continuous bonds on your behalf. For a continuous bond, the broker submits an application to a surety, and once approved, the bond is filed electronically with CBP through the ACE (Automated Commercial Environment) system.
• Through a standalone bond provider: Companies like Roanoke Trade, Global Surety, and others specialize in customs bonds and can issue bonds without requiring you to have a full customs broker relationship. This can be useful if you want to hold your own continuous bond independently of any one broker.
• What you will need to apply: your importer of record information (name, address, EIN/IRS number), the type of bond (single-entry or continuous), and for a continuous bond, an estimate of your annual import volume and duty liability.

Bond activation timeline: a continuous bond typically takes 1 to 3 business days to issue and file with CBP after your application is approved. Plan ahead -- if you have a shipment arriving, you need the bond filed before the ISF deadline (24 hours before loading at origin).

What Happens If You Don't Have a Customs Bond

Without a valid customs bond, CBP will not release your shipment. The cargo remains in customs custody at the port, accumulating storage and demurrage fees. For ocean shipments, free time at the terminal is typically 3 to 5 days after vessel arrival. After that, fees run from $75 to $300 per day depending on the port and terminal.

In addition to storage costs, there is no shortcut: you cannot retroactively file a bond after the shipment arrives. The bond must be on file before the customs entry is submitted. Your customs broker cannot file entry without a bond in place.

The practical solution if you are caught without a bond on an arriving shipment: contact your customs broker immediately. Most brokers can obtain a single-entry bond within hours and file the entry the same day. It is not ideal, but it resolves the problem before significant storage fees accumulate.

Customs Bond vs Cargo Insurance

These two instruments are frequently confused because they both involve third parties and financial guarantees related to imports. They serve entirely different purposes:

• Customs bond: Required by CBP. Guarantees that import duties, taxes, and fees will be paid to the US government. Does not protect the importer's cargo or financial interest.
• Cargo insurance: Optional (but strongly recommended). Purchased by the importer to cover the commercial value of the goods during transit against physical loss or damage. Has nothing to do with customs compliance.

You need both. A customs bond lets your shipment through customs. Cargo insurance protects the value of what is inside.
