Continuous vs. Single-Entry Customs Bonds: Which Do You Need?

Every commercial import into the United States valued over $2,500 requires a customs bond — a financial guarantee to U.S. Customs and Border Protection that duties, taxes, and fees will be paid. If you import through Miami with any regularity, choosing the right bond type is one of the easiest ways to cut per-shipment costs. Here’s how the two options compare.

What a customs bond actually guarantees

A customs bond is not insurance for your cargo. It protects the U.S. government, not you: if an importer fails to pay duties, penalties, or fees, CBP collects from the surety company that issued the bond, and the surety then pursues the importer. No bond, no entry — your customs broker cannot clear your shipment without one.

Single-entry bonds: pay per shipment

A single-entry bond (SEB) covers exactly one import entry. The bond amount generally equals the value of the goods plus duties, taxes, and fees, with higher multiples for merchandise subject to other agency requirements like FDA.

Single-entry bonds make sense when you import once or twice a year, when you’re testing a new product line with a trial shipment, or when a one-off piece of equipment is arriving. The catch: on ocean shipments an SEB also requires a separate ISF bond for the Importer Security Filing, adding cost to every shipment. Fees stack up fast.

Continuous bonds: one bond, unlimited entries

A continuous bond covers all your entries at all U.S. ports for a full year, and it includes ISF coverage. The minimum bond amount is $50,000 or 10 percent of the duties, taxes, and fees you paid in the previous 12 months, whichever is greater.

The break-even math is simple: most importers who bring in three or more ocean shipments a year save money with a continuous bond. Beyond price, a continuous bond removes friction — no waiting on bond approval per shipment, no ISF bond surprises, and smoother processing at every port including Miami.

How bond type interacts with bonded storage

Importers often confuse their import bond with a warehouse’s bond. They are different instruments. A bonded warehouse operates under its own custodial bond with CBP, which is what allows it to hold your goods with duties deferred for up to five years.

If you enter goods into bonded storage under a warehouse entry, you still need your own bond as importer, and duty is paid only when goods are withdrawn for consumption. This combination — continuous bond plus bonded storage — is popular with Miami distributors serving Latin America, because goods that are re-exported from bond never incur U.S. duty at all. Pair that with export consolidation through an IBEC and you have a duty-efficient regional distribution model.

Choosing, buying, and sizing your bond

Your customs broker or a surety agent can write either bond type, usually same-day. When sizing a continuous bond, look forward, not just backward: if tariffs on your product category are rising or your volumes are growing, CBP may demand a larger bond mid-year (“insufficiency”), which can freeze your entries until resolved. Review your bond amount every quarter against duty projections, especially in a shifting tariff environment.

Frequently asked questions

How much does a continuous customs bond cost?

Premiums vary by surety and importer risk profile, but a $50,000 minimum continuous bond typically costs a few hundred dollars per year. Importers with three or more ocean shipments annually usually come out ahead versus single-entry bonds.

Do I need a customs bond if my goods go into a bonded warehouse?

Yes. The warehouse’s custodial bond covers the facility’s obligations, not yours. You file a warehouse entry under your own bond, and duties are deferred until the goods are withdrawn for U.S. consumption — or never paid if they are re-exported.

What happens if my bond is deemed insufficient?

CBP issues an insufficiency notice and you must increase the bond amount, or new entries will be rejected. Monitoring duty outlays quarterly prevents the disruption.
