Customs Bonds: Single Entry vs Continuous Bond for Importers
A customs bond is a financial guarantee that you'll pay import duties and comply with CBP regulations. If you import commercially, you almost certainly need one — but most importers don't fully understand what they're paying for or how to minimize that cost.
What Is a Customs Bond?
A customs bond is a legally binding contract among three parties: the importer (the “principal”), a licensed surety company (the “surety”), and US Customs and Border Protection (the “obligee”). It guarantees that the importer will pay all applicable duties, taxes, and fees and will comply with CBP requirements. If the importer fails to do so, the surety company is obligated to pay CBP up to the bond's face value.
Think of it as insurance for CBP — not for you. The bond protects CBP's revenue interest in your shipments. You're still responsible for paying duties; the bond is just CBP's guarantee that it will get paid even if you default or disappear.
When Is a Customs Bond Required?
A customs bond is required for any formal entry filed with CBP. Formal entry is required for:
- Commercial shipments with a value of $2,500 or more (the formal entry threshold)
- Shipments of any value that contain goods subject to antidumping or countervailing duty orders
- Shipments requiring a federal permit, license, or other release authorization (FDA-regulated items, firearms, certain chemicals)
- Goods entered into a bonded warehouse or Foreign Trade Zone (FTZ)
- Certain carnets (temporary import bonds for equipment used at trade shows, etc.)
Informal entries (shipments under $2,500 that don't require federal licensing) and de minimis entries (under $800) do not require a customs bond. If you're importing small, low-value test orders, you may not need a bond yet. Once you move to commercial quantities, you will.
Single Entry Bond vs. Continuous Bond
| Feature | Single Entry Bond | Continuous Bond |
|---|---|---|
| Coverage | One shipment only | All entries for 12 months (renewable) |
| Typical cost | $50–$125 per shipment | $500–$1,500 per year |
| Bond amount | Value of goods + duties (minimum $100) | Typically $50,000 minimum |
| Break-even point | N/A — use for 1–2 shipments/year | Cheaper than single if importing 5+ times/year |
| Who it's for | Occasional importers, one-off shipments | Regular importers with consistent import volume |
| Setup time | Same day (filed per shipment) | A few business days for initial setup |
Single entry bonds
A single transaction bond (STB) covers one shipment only. You pay a premium each time you import. The cost is typically $50–$125 per shipment but can be higher for large shipments or high-risk goods (perishables, goods subject to AD/CVD orders). Your customs broker can arrange this per shipment — you don't have to deal with the surety company directly.
Single entry bonds make sense when you import very infrequently — say, once or twice per year. Beyond that, the math favors a continuous bond.
Continuous bonds
A continuous bond covers all your formal entries over a 12-month period. The typical minimum bond amount is $50,000 (or 10% of the prior year's duty, tax, and fee payments, whichever is higher). The annual premium for a $50,000 continuous bond is typically $500–$750.
If your import activity is growing, CBP may require a bond increase. Bond sufficiency reviews are common when your imports increase — CBP looks at your prior 12 months of duties and requires the bond to be at least 10% of that amount.
How to Get a Customs Bond
Option 1: Through your customs broker (easiest)
Most licensed customs brokers have relationships with surety companies and can arrange both single entry and continuous bonds on your behalf. Your broker handles the paperwork, the surety company issues the bond, and you pay the premium. This is the easiest path for most importers.
Option 2: Directly through a surety company
You can go directly to a licensed surety company (Roanoke Trade, Avalon Risk Management, International Surety Group, and others specialize in customs bonds). This may be slightly cheaper than going through a broker, and you can manage the bond renewal yourself.
Option 3: Through an online customs bond provider
Several online platforms (Customs City, Flexport, and similar) offer instant continuous bond issuance for standard importers. Application is online, pricing is transparent, and you can get bonded quickly. Good option for straightforward import profiles.
Bond Amount Requirements
The required bond amount is not arbitrary. CBP sets minimums based on your import activity:
- Minimum for continuous bonds: $50,000 for importers with less than $500,000 in annual duties/fees
- Higher volume importers: Bond must be at least 10% of prior year's duties, taxes, and fees, rounded up to the next $10,000 increment
- AD/CVD importers: CBP may require higher bond amounts — sometimes 3x the normal calculation — for importers of goods subject to antidumping or countervailing duties
- Continuous bonds are renewed annually and CBP reviews sufficiency regularly
Common Customs Bond Mistakes
Using single entry bonds for regular imports
If you're importing more than 4–5 times per year, single entry bonds cost more than a continuous bond. Calculate the break-even: if your single entry bond costs $75 per shipment and you import 10 times a year, you're paying $750 for less coverage than a $600 continuous bond would provide.
Not monitoring bond sufficiency
A $50,000 bond that was adequate when you imported $100,000 in goods per year becomes insufficient as your business grows. CBP can flag entries and demand a bond increase before releasing your goods. Stay ahead of this by calculating 10% of your projected annual duty payments annually.
Confusing the bond with duty payment
The bond premium you pay the surety is not your duty payment — it's the fee for the guarantee. You still owe CBP the full duty amount separately. Many new importers conflate the two.
Not understanding AD/CVD bond requirements
If your goods are subject to antidumping or countervailing duty orders, your bond requirement may be significantly higher and CBP may require a single entry bond for each shipment even if you have a continuous bond. Check whether your products are subject to AD/CVD orders before setting up your bond.
Bonds for Bonded Warehouses and FTZs
If you plan to store goods in a bonded warehouse or import them into a Foreign Trade Zone (FTZ), separate bond requirements apply. Bonded warehouse operators have their own bonds, and goods stored there are covered under the operator's bond. When goods are withdrawn for US consumption, your importer bond covers the entry. See our guide to bonded warehouses and FTZs for details on duty deferral strategies.
What Happens If You Don't Have a Bond?
Without a valid customs bond on file for a formal entry, CBP will not release your goods from the port. Your shipment will sit at the port — accumulating storage and demurrage fees — until the bond is in place. At major ports during peak season, demurrage fees can reach hundreds of dollars per day. Getting a bond after the fact takes days. The practical lesson: set up your bond before your first commercial shipment arrives.
