A customs bond is a guarantee, issued by a surety, that an importer will pay its duties, taxes and fees and follow CBP's rules. Every formal entry needs one. A continuous bond covers all entries for a year and is generally set at the greater of $50,000 or 10% of the duties, taxes and fees paid in the prior 12 months. A single transaction bond covers one entry.
CBP generally sets the minimum at 10% of the duties, taxes and fees the importer paid in the previous 12 months, with a $50,000 floor, rounded up. When tariffs rise, duties rise, and the bond can become too small.
When duty paid outgrows the bond, CBP issues a notice that the bond is insufficient, and the importer has to file a larger bond quickly. Higher tariff rates in recent years have pushed many importers into this, often without warning.
Bonds are purchased from a surety, usually through a customs broker, and filed with CBP electronically. The premium is a small percentage of the bond amount and depends on the importer's finances.
Does the bond cover IEEPA refunds? Refunds are paid by ACH. The bond guarantees payments to CBP, not from it.
Can I lower my bond if duties fall? Yes, at renewal, if the prior 12 months support a smaller amount.
Caspian's audits show the duty you actually paid and why, which feeds bond sizing, and our brokers handle drawback bonds. See our trade compliance advisory.
