Customs Bonds 2026: Do You Need One and What They Cost
A US customs bond is a guarantee that CBP will be paid even if you (the importer) don't pay. Without one, you cannot legally clear a commercial shipment above $2,500. With the wrong one, you pay too much for coverage or get caught short when CBP demands more.
The Trump-era tariff stack has made bonds dramatically more expensive — because bond size scales with duty exposure, and duty exposure tripled or quadrupled for many importers in 2025. This guide explains what bonds are, when you need each type, and how the 2026 math works.
What a customs bond actually is
A customs bond is a three-party agreement: the principal (you, the importer), the surety company (the insurer underwriting the bond), and CBP (the beneficiary). If you fail to pay duties, taxes, or penalties, CBP collects from the surety. The surety then comes after you for reimbursement.
You pay the surety a premium for taking on that risk. The premium is much smaller than the bond's face value because the surety expects you to actually pay your obligations.
When you need a bond
| Situation | Bond required? |
|---|---|
| Commercial shipment > $2,500 | Yes |
| Shipment subject to FDA/FCC/CPSC/USDA regardless of value | Yes |
| Antidumping/countervailing duty (AD/CVD) goods | Yes (often increased) |
| Bonded warehouse usage | Yes |
| Foreign Trade Zone operation | Yes |
| Personal use, single shipment < $2,500 | No |
| Section 321 (de minimis) shipments under $800 | No (where still applicable) |
Note: the $800 de minimis exception largely ended in 2025 for Chinese-origin goods. See our consumer platforms guide.
The two types of bonds
Single Entry Bond (SEB)
Covers one specific shipment. Bond amount = total value of goods + duties + fees, typically rounded up. Premium = 1–3% of the bond amount, with a $50 minimum.
| When to use SEB | Why |
|---|---|
| One-off shipments | No reason to pay for continuous coverage |
| First-time importers testing the waters | Lower upfront cost |
| Annual import volume < $300,000 | Math favors per-entry pricing |
| Trial shipments before scaling | Operationally simpler |
Continuous Bond
Covers all your shipments for 12 months. Bond amount = 10% of your annual duties, taxes, and fees, with a $50,000 minimum. Premium = $400–$650/year for the basic $50,000 bond, scaling up with coverage size.
| When to use continuous | Why |
|---|---|
| More than 5–10 entries per year | Cheaper per shipment |
| Annual import volume > $300,000 | SEB premiums add up faster |
| You import OGA-regulated goods (FDA etc.) | Streamlined for repeat filings |
| You use a customs broker continuously | Broker manages renewal |
How Trump tariffs blew up bond sizes in 2025–2026
Continuous bond size is set at 10% of your projected annual duty. When tariffs jumped, duty exposure jumped, and CBP began issuing bond sufficiency notices requiring importers to increase their bonds within 30 days.
A real example for a small importer of Chinese electronics:
| Year | Annual import value | Annual duty | Required bond | Annual premium |
|---|---|---|---|---|
| 2024 | $500,000 | $30,000 | $50,000 (minimum) | $450 |
| 2025 | $500,000 | $185,000 | $200,000 | $1,800 |
| 2026 | $500,000 | $275,000 | $300,000 | $2,700 |
Same import volume, but the bond premium rose 6× because duty exposure rose 9×. Many small importers were caught off-guard in 2025 and had shipments held until the bond was increased.
How to get a customs bond
- Most importers go through their customs broker. The broker has a surety relationship and handles the application.
- Direct from a surety company. Cheaper if you have volume but requires direct underwriting relationship.
- Through a freight forwarder if they have an in-house brokerage.
Underwriting requirements vary by surety. Typical requirements:
- Business credit check.
- Owner's personal credit (for small businesses).
- 2 years of financial statements (for bonds > $100,000).
- EIN and IOR documentation.
- Signed indemnity agreement.
Bond sufficiency: how to avoid surprises
CBP monitors your duty payments quarterly. If you trend higher than your bond covers, CBP issues a sufficiency notice. You have 30 days to:
- Increase the continuous bond, OR
- Switch to single-entry bonds for upcoming shipments, OR
- Demonstrate why the trend is temporary.
If you don't act, CBP can refuse future entries until the bond is sufficient. To stay ahead:
- Review your bond annually with your broker.
- Reforecast duty after any major tariff change.
- Add a buffer of 20%–30% above expected duty when sizing the bond.
- Have your broker's surety pre-approve a bond increase so it's quick when needed.
The math of single-entry vs continuous
Rule of thumb: continuous bond becomes cheaper around 10+ entries per year for typical importers.
| Entries per year | SEB total cost | Continuous cost | Cheaper option |
|---|---|---|---|
| 2 | $150–$300 | $450 | SEB |
| 5 | $375–$750 | $450 | Continuous |
| 10 | $750–$1,500 | $450 | Continuous (much) |
| 50 | $3,750–$7,500 | $450–$2,700 | Continuous (huge savings) |
This assumes basic $50,000 continuous coverage. For larger bonds, redo the math with the actual coverage size and premium.
Common bond mistakes
- Sizing the bond on last year's duty. Tariff rates change. Reforecast.
- Letting the continuous bond expire. No bond = no entries = held cargo. Set calendar reminders.
- Using a single-entry bond when you should have continuous. Each SEB takes 1–3 days to underwrite for first-time users.
- Not disclosing AD/CVD exposure to the surety. Underwriting changes; bond may be voided.
- Forgetting to update the bond when you change broker. Different brokers have different sureties; you may need a new bond.
Frequently asked questions
When do I need a customs bond?
For any commercial shipment valued over $2,500, or any shipment subject to other government agency requirements (FDA, FCC, CPSC, USDA) regardless of value.
How much does a customs bond cost in 2026?
A basic continuous bond of $50,000 coverage runs $400–$650 per year. Single-entry bonds run 1–3% of the bond amount. Larger bonds cost more proportionally.
Can I share a customs bond with another importer?
No. Bonds are individual to your IOR. You cannot legally use someone else's bond.
What happens if I don't have enough bond?
CBP issues a sufficiency notice. You have 30 days to increase coverage or future entries can be refused.
Do bonds cover penalties for ISF violations?
Yes. ISF violation penalties ($5,000 per shipment, see our ISF guide) are collected against your bond if unpaid.
How do I know what my bond should be sized at?
10% of projected annual duties, taxes, and fees, with a $50,000 minimum for continuous. Your customs broker calculates and recommends a buffer.
