What Is a Customs Bond? Types, Cost & When You Need One

CBP will not release a commercial shipment into US commerce without a bond on file, unless you pay every duty, tax, and fee upfront. For most importers, that single requirement stands between a container at the port and the goods reaching your warehouse.

A customs bond is the financial guarantee that lets your goods enter at all.

Getting the type or the amount wrong is the most expensive mistake a new importer makes, because an insufficient bond triggers CBP holds and suspended entries.

What Is a Customs Bond?

A US customs bond is a legally binding contract that guarantees CBP will collect the duties, taxes, and fees owed on imported goods, and that the importer will comply with customs law. It is a three-party agreement between the importer, a surety company, and CBP as the beneficiary.

The structure matters because it decides who pays when something goes wrong. The importer is the principal, the surety is a Treasury-approved insurance company, and CBP is the party protected.

If the importer fails to pay, CBP demands payment from the surety, which then recovers the money from the importer.

Under 19 U.S.C. § 1623 and 19 CFR Part 113, CBP has the authority to require this security, and the standard CBP bond instrument is Form 301.

A US customs bond does not pay for your duties; it guarantees to the government that they will be paid. To ground planning in real activity, you can analyse shipment corridors and counterparties on yTrade before you file.

When Is a Customs Bond Required?

A bond is required for any commercial import valued at $2,500 or more, and for any shipment subject to a partner government agency such as the FDA, USDA, or EPA, regardless of value. Duty-free statUS does not remove the requirement.

The value threshold is where importers most often misjudge their obligation.

A shipment can be duty-free and still need a bond, because the guarantee covers compliance and other agency requirements, not only the duty owed.

Several situations trigger the requirement:

• Formal commercial entries valued at $2,500 or more at any US port.
• Regulated goods subject to an agency like the FDA or USDA, even below $2,500.
• Ocean freight, where the Importer Security Filing must be backed by a bond.

One point catches ocean importers specifically. When is a customs bond required for the Importer Security Filing? For every ocean shipment.

A continuous bond already covers that filing, whereas a single entry bond needs a separate ISF bond alongside it. For the party who carries this obligation, see our guide to what a customs broker does.

What Are the Types of Customs Bond?

The two types are the single entry bond, which covers one shipment at one port, and the continuous bond, which covers all your entries at all US ports for 12 months. Frequent importers use a continuous US bond; occasional importers use a single entry bond.

The choice turns on how often you import, and the cost of math favours regularity.

A single entry bond suits a one-off or infrequent shipment, while a continuous bond renews automatically and covers unlimited entries for the year.

Feature	Single entry bond	continuous bond
Coverage	One shipment, one port	All entries, all ports
Duration	That entry only	12 months, self-renewing
ISF for ocean freight	Separate ISF bond needed	Included
Best for	Occasional importers	Regular importers

The continuous bond also removes per-shipment paperwork. To confirm a counterparty ships what and where they claim before you commit, verify a supplier's real shipment history against customs data.

How Does CBP Set the Bond Amounts?

CBP sets the continuous bond amount at 10% of the duties, taxes, and fees you paid over the prior 12 months, with a minimum of $50,000, rounded in $10,000 multiples up to $100,000. A single entry bond is generally the entered value of the goods plus all duties, taxes, and fees.

The two bonds use different formulas for their bond amounts, and the continuous figure moves with your import volume.

According to CBP, the continuous bond amount is the greater of $50,000 or 10% of prior-year duties, taxes, and fees. The imported value itself does not set a limit.

• continuous bond amount: 10% of prior-year duties, taxes, and fees, minimum $50,000, rounded up in $10,000 steps to $100,000, then $100,000 increments.
• Single entry bond amount: generally the total entered value plus duties, taxes, and fees; up to three times the value for restricted goods.
• Premium: you pay the surety a premium, often around $400 to $700 a year for the minimum $50,000 continuous US bond, not the full bond value.

A current pressure point deserves attention. Because Section 232, 301, and other additional duties are stacking on the same shipments, importers' trailing 12-month duty totals are rising, which pushes the 10% bond calculation higher at renewal.

If your bond becomes insufficient, CBP issues an insufficient bond notice and can suspend your entries until you raise it. For how classification drives those duty totals, see our guide on how to find an HS code.

How Do You Get a Customs Bond?

You obtain a custom bond through a Treasury-approved surety company, usually arranged by your customs broker under a Power of Attorney. Once the broker files it with CBP, you are US bonded for imports, and the bond ties to your importer of record number for future entries.

Most importers hold the standard CBP bond under activity code 1, becoming US bonded for all entries, and never arrange coverage shipment by shipment again.

Knowing how to get a customs bond comes down to four steps in order:

1. Choose the bond type based on how often you import, single entry for a one-off, continuous for regular shipments.
2. Appoint a surety or broker, signing a Power of Attorney that lets the broker transact customs business in your name.
3. File CBP Form 301, which the broker submits to CBP on your behalf.
4. Check sufficiency regularly, since rising duty totals can leave a continuous US bond underfunded within a year.

To keep import documentation and counterparties verified, yTrade's customs data tools support that ongoing check.

Conclusion

A customs bond is the financial guarantee that lets your goods enter the US, a three-party contract securing the duties you owe and your compliance with import law. The requirement starts at $2,500, or at any value for agency-regulated goods.

The one number that changes everything is the continuous bond formula: 10% of prior-year duties with a $50,000 minimum, now rising as tariffs stack. Match the type to your import frequency, file before the goods arrive, and recheck the amount yearly.

Frequently Asked Questions

How much does a customs bond cost?

The premium is a fraction of the bond amount, not the full value. A minimum $50,000 continuous bond commonly costs around $400 to $700 per year, paid to the surety. A single entry custom bond is priced per shipment, typically a small percentage of the entered value plus duties.

What happens if my customs bond is insufficient?

CBP issues an insufficient bond notice and can suspend your ability to file entries until you increase the bond amount. Because additional tariffs raise trailing-12-month duty totals, a bond set last year can fall short at renewal, so checking sufficiency regularly prevents shipment holds.

Is a customs bond the same as a customs bonded warehouse?

No. A customs bond is a financial guarantee to CBP for duty payment and compliance. A customs bonded warehouse is a secure facility where imported goods are stored with duties deferred until they are withdrawn. The two are related to customs security but serve different purposes.

Can I import without a customs bond?

Only in limited cases. Shipments below the de minimis threshold or under $2,500 without agency requirements may not need a bond. For most formal commercial entries, CBP will not release the goods without a bond unless you pay all duties, taxes, and fees upfront.
