Every formal entry needs a bond behind it, and importers choose, usually once and by habit, between a single transaction bond per entry and a continuous bond covering all entries for a year. The right answer is arithmetic: how many entries, at what duties, with what risk flags. It is also a risk decision, because the bond is the surety's promise, and the surety prices how much it trusts your compliance, not just your volume.
How the amounts are set
A continuous bond's minimum is generally set at 10 percent of the duties, taxes, and fees paid in the previous twelve months, with a floor amount that applies to small importers, and CBP or the surety can require more where the risk profile warrants it, notably for goods subject to antidumping or countervailing duties or partner government agency requirements.
A single transaction bond is sized to the entry: typically the total entered value plus duties and fees for ordinary goods, and multiples of duties for restricted or high risk categories. Per entry that looks small. Multiplied across a year of entries, the premiums routinely exceed a continuous bond's annual premium by a wide margin.
The breakeven, roughly
Importers entering more than a handful of times a year usually come out ahead on a continuous bond on premium alone, before counting the operational benefit: no per entry bond procurement slowing down release, no single bond paperwork per shipment, and a standing facility for ISF filings, which themselves require bond coverage.
The exceptions are real: a genuine one off import, a single project shipment, or an importer whose surety terms for a continuous bond are punitive because of the commodity. Run both quotes against your actual entry count from the last twelve months in ACE rather than estimating from memory. Volume is always higher than memory says.
Stacking and saturation, the part nobody warns about
A continuous bond is an aggregate exposure for the surety. If your duties spike, through a tariff change, a volume surge, or an AD/CVD determination, the bond amount set from last year's duties can become insufficient, and CBP monitors bond sufficiency. An insufficient bond can mean entries held, a required bond increase on a deadline, and a surety conversation you wanted to have at renewal moved to this week.
Watch the ratio as duties change, not once a year. Importers caught by the recent rounds of tariff increases learned that a bond sized for the old rate stack saturates quietly and announces itself at the worst moment, with cargo on the water.
Bonds are underwriting, act accordingly
Sureties can demand collateral, financials, or indemnity terms that reflect your claims and compliance history, and a bond terminated by a surety leaves a gap that stops entries until a replacement is active. Treat the surety like a credit relationship: clean entry record, responsive corrections, no surprises.
Confirm bond type, amount, and sufficiency for your import profile with a licensed customs broker or the surety before a volume or tariff change lands, not after the first held entry.

Frequently asked questions
What is a continuous customs bond?
A bond covering all of an importer's transactions over a one year term, generally sized at a minimum of 10 percent of the previous year's duties, taxes, and fees. It replaces per entry bonds for regular importers.
When is a single transaction bond better?
For genuine one off or very occasional imports, or a single project shipment, where the annual continuous premium and setup are not justified by entry volume.
What is bond saturation?
When rising duties or volumes make an existing continuous bond amount insufficient relative to current liability. CBP monitors sufficiency, and an insufficient bond can hold entries until it is increased.
