Nearly every commercial import into the United States is backed by a customs bond, yet most importers give it little thought until something goes wrong. The bond is a guarantee to CBP that duties will be paid and obligations met — and when they are not, CBP makes a claim against it. Understanding how the bond works, the difference between the two main types, and what a claim means is essential to managing import risk.
A customs bond guarantees your obligations to CBP
A customs bond is a three-party guarantee — between the importer, a surety, and CBP — that duties, taxes, and compliance obligations will be met. If the importer fails to pay or comply, CBP claims against the bond, the surety pays, and the surety then seeks reimbursement from the importer. The importer is ultimately on the hook regardless.
Continuous vs. Single-Entry Bonds
There are two main ways to bond imports, and which one applies affects both cost and exposure.
| Bond type | What it covers | Typical use |
|---|---|---|
| Continuous bond | All of an importer’s entries nationwide over a one-year period | Regular or high-volume importers |
| Single-entry bond | One specific shipment or entry | Occasional imports, or shipments CBP treats as higher risk |
A single-entry bond covers just one transaction, and CBP often requires one — sometimes in an elevated amount — for shipments it considers higher risk, such as goods subject to antidumping or countervailing duties or those regulated by another agency. For merchandise carrying AD/CVD exposure in particular, single-entry bond amounts can be set well above the ordinary formula to secure the potentially large final duty.
What Triggers a Claim Against the Bond
A bond claim arises when an importer breaches one of the obligations the bond secures. The most common triggers are a failure to pay duties, taxes, or fees when due; a failure to redeliver merchandise on CBP’s demand; late or missing filings; and failure to meet the conditions attached to regulated goods. When any of these happens, CBP issues a claim — frequently in the form of liquidated damages — against the bond.
When the surety pays, it comes back to you
Importers sometimes assume the bond absorbs the loss. It does not. The surety that pays CBP has a right of reimbursement against the importer, and it will pursue it. A bond claim is not a shield — it is a mechanism that ensures CBP gets paid and then routes the cost back to the importer, often with the surety’s own demands on top.
Insufficient Bonds and Stacking
Bond adequacy is its own risk. If CBP determines an importer’s continuous bond is insufficient for its duty exposure — a common issue when tariffs rise or AD/CVD liability grows — it can require the bond to be increased or demand single-entry bonds in the meantime, disrupting the flow of shipments. Keeping bond amounts aligned with actual duty exposure is part of a sound import compliance program, particularly in an era of shifting tariff rates.
If you have received a bond claim or a liquidated damages demand, or CBP is questioning your bond’s sufficiency, the claim can often be contested or mitigated — but the deadlines are firm. A customs and international trade lawyer can assess the claim, petition for relief, and help keep a bond problem from stopping your imports.

Frequently Asked Questions
What is a customs bond?
A customs bond is a guarantee among the importer, a surety, and CBP that duties, taxes, and compliance obligations will be met. If the importer fails to pay or comply, CBP claims against the bond, the surety pays, and the surety then seeks reimbursement from the importer.
What is the difference between a continuous and single-entry bond?
A continuous bond covers all of an importer’s entries nationwide for a year and suits regular importers. A single-entry bond covers one specific shipment and is common for occasional imports or shipments CBP treats as higher risk, such as goods subject to AD/CVD.
What happens when CBP makes a claim against my bond?
CBP issues a claim — often as liquidated damages — for the breached obligation. The surety pays CBP and then seeks reimbursement from the importer. The claim can often be contested or mitigated through a petition, but the deadline is firm.
Why did CBP say my bond is insufficient?
CBP can find a continuous bond insufficient when an importer’s duty exposure grows — for example, when tariffs rise or AD/CVD liability increases. It can then require a larger bond or single-entry bonds in the interim, which can disrupt shipments until the bond is adjusted.
Facing a bond claim or sufficiency demand?
Bond claims can be contested or mitigated, but the deadlines are firm. A customs attorney can respond and keep a bond problem from halting your imports.
