Customs Bond Cost Calculator (2026)
Estimate what a CBP customs bond costs in 2026, compare a continuous import bond against single transaction bonds, and find the shipment count where a continuous bond starts paying for itself.
Your Import Profile
Each customs clearance (CBP entry summary) counts as one.
Declared invoice value of the goods on a typical shipment.
Base HTS duty plus Section 301/232 and 2025 IEEPA tariffs. China-origin goods often stack to 45%+ in 2026.
Entry Details
Ocean entries add a Harbor Maintenance Fee and an ISF bond on single-entry filings.
Partner-government-agency or quota merchandise is commonly bonded at three times entered value on single-transaction bonds, which raises the per-entry cost sharply.
Quick context
A CBP import bond is mandatory on every commercial entry over $2,500 (and on lower-value entries of regulated goods). It is a financial guarantee to CBP — not insurance for you. The question is simply whether one annual continuous bond is cheaper than buying a fresh single-transaction bond on every shipment.
At 12 entries per year, buying a single-transaction bond on every shipment costs about $4,665. One continuous bond covers all of them — plus every ISF filing — for roughly $500, saving about $4,165 a year. The continuous bond pays for itself after just 2 entries.
Annual Bond Cost: Single-Entry vs Continuous
Cost Breakdown
| Line | Amount | Notes |
|---|---|---|
| Duties, taxes & fees per entry | $11,462 | Estimated duty plus MPF and (ocean) HMF on a typical shipment. |
| Annual duties, taxes & fees | $137,546 | Drives the CBP 10% continuous-bond sizing rule. |
| Required continuous bond amount | $50,000 | Greater of $50,000 or 10% of annual duties/taxes/fees, rounded up. |
| Continuous bond annual premium | $500 | Surety premium for the bond above; covers unlimited entries for 12 months. |
| Single-transaction bond per entry | $339 | Rated at $6/$1,000 of $56,462 coverage, $60 minimum. |
| ISF bond per entry | $50 | Separate 10+2 bond required on ocean entries. |
| Single-entry cost per shipment | $389 | Transaction bond plus ISF bond, paid fresh on every entry. |
| Annual single-entry total | $4,665 | Compare against the $500 continuous bond. |
Bonds are one line in a much larger import cost stack.
Duty, MPF, HMF, drayage, demurrage and warehousing usually dwarf the bond premium. If you are sizing a US import program, get a free 3PL or bonded-warehouse quote — broker introductions available on request.
How this is calculated
The continuous bond amount follows CBP's sizing rule: the greater of $50,000 or 10% of the duties, taxes and fees paid in the prior 12 months, rounded up to the nearest $10,000 below $100,000 and to the nearest $100,000 above it. Annual duties, taxes and fees are estimated from your entry count, average value, duty rate, the Merchandise Processing Fee (0.3464%, min $33.58, max $651.50 per entry) and, for ocean freight, the Harbor Maintenance Fee (0.125%). Continuous bond premiums are blended from 2026 surety-market survey data — roughly $400–$600 for a standard $50,000 bond, scaling up with bond size. Single-transaction bonds are rated at about $6 per $1,000 of coverage with a $60 minimum, plus a $50 ISF bond on ocean entries; partner-government-agency or quota goods are bonded at three times entered value. Output is a directional estimate — your customs broker or a licensed surety will quote the actual premium based on credit, commodity and claims history.
Why Customs Bond Costs Are Climbing in 2026
Every US importer needs a customs bond — it is a financial guarantee to CBP that duties, taxes, fees, and penalties will be paid. For years the math was simple: a $50,000 continuous bond cost a few hundred dollars and that was that. In 2026 the calculation has changed, and not because premium rates moved much.
The continuous bond amount is set at 10% of the duties, taxes, and fees an importer paid over the prior 12 months. When Section 301, Section 232, and the 2025 IEEPA reciprocal tariffs stacked effective duty rates from single digits to 25–55% on a large share of imports, importers' duty bills multiplied — and so did their required bond amounts. CBP has responded with a wave of bond insufficiency notices, and an insufficient bond can get entries held at the port.
That makes two questions worth re-checking every year: is your bond still large enough to cover your current duty exposure, and given your shipment frequency, are you buying the cheaper type of bond? This calculator answers both in about thirty seconds.
Continuous Bond vs Single Transaction Bond
There are two ways to satisfy the CBP bond requirement. The right answer is almost entirely a function of how often you import.
| Feature | Continuous Bond | Single Transaction Bond |
|---|---|---|
| Coverage period | 12 months, auto-renews | One entry only |
| Number of entries covered | Unlimited, all US ports | Exactly one |
| ISF (10+2) filings | Included at no extra cost | Separate ISF bond per ocean entry (~$50) |
| Typical 2026 cost | $400-$600/yr for a $50K bond | $5-$7 per $1,000 of coverage, ~$60 min |
| Bond amount | Greater of $50K or 10% of annual duties/taxes/fees | Entered value + duties (3x value for PGA/quota goods) |
| Best for | 4+ entries per year, ongoing import programs | One-off or first-time shipments, testing a supplier |

Three Things Importers Get Wrong About Bonds
- Treating the bond as insurance. A customs bond protects CBP, not you. If the surety pays CBP on your behalf, it will recover that money from you. To protect the goods themselves against loss or damage you need cargo insurance — see our Cargo Insurance Costs guide.
- Never resizing the bond. The required amount tracks your duty bill. Importers who set a $50,000 bond years ago and then grew — or simply absorbed 2026 tariff increases — are often carrying an insufficient bond without knowing it, until CBP sends a notice. Re-run the numbers annually.
- Buying single transaction bonds out of habit. A first shipment on a single entry bond makes sense. The fourth, fifth, and tenth do not. Past the break-even point this calculator shows, every additional single entry bond is money a continuous bond would have saved.
Bonds also pair with duty-deferral strategy. Importers running bonded warehouses or foreign trade zones still need a continuous bond, but those structures change when and how much duty — and therefore bond — they ultimately carry.
