Continuous Entry Bond: Customs Bond Guide

A customs bond is a legally binding contract, backed by a surety company, that guarantees U.S. Customs will be paid all duties, taxes, and fees an importer owes.

A customs bond, also known as a customs surety bond or import bond, is a contract that guarantees U.S. Customs and Border Protection (CBP) will be paid all duties, taxes, and fees owed on imported goods. It's essentially an insurance policy that protects the U.S. government in case an importer fails to fulfill their obligations.

The customs bond involves three parties in a legal agreement:

1. 1

   Principal (Importer)

   The person or company importing goods into the United States. This is you, the importer of record.
2. 2

   Surety (Bond Company)

   The insurance company or bonding company that issues the bond and guarantees payment to CBP if the importer defaults.
3. 3

   Obligee (CBP)

   U.S. Customs and Border Protection, the government agency that collects duties and enforces import regulations.

What Happens When CBP Files a Claim on Your Bond?

When an importer fails to pay duties or violates a bond condition, CBP notifies the surety company and files a formal claim against the bond. The surety pays CBP the amount owed, then demands full reimbursement from you—the importer remains legally responsible for every dollar the surety pays out. If you don't reimburse the surety, you face collection action, damaged credit, and the surety refusing to renew your bond. Because CBP requires an active bond for nearly all commercial imports, an unresolved claim can effectively shut down your ability to import.

What Customs Bonds Cover

A customs bond guarantees payment and compliance for various import-related obligations:

• Import duties and taxes owed on merchandise
• Merchandise Processing Fees (MPF) and other CBP charges
• Penalties for violations of customs laws and regulations
• Storage and transportation charges for seized or detained cargo
• Additional duties assessed during post-entry audits

U.S. Customs and Border Protection requires customs bonds for virtually all commercial imports to ensure compliance and protect government revenue. Here's why bonds are mandatory:

There are two primary types of customs bonds available to importers:

Continuous Bond

A continuous bond (also called a continuous entry bond) remains in effect for one year from its effective date and automatically covers all your import entries during that period. This is the most common and cost-effective option for regular importers.

Coverage & Benefits:

• Covers unlimited shipments for 12 months
• Valid at all U.S. ports of entry
• One annual premium payment
• Automatically renews each year
• Includes ISF (Importer Security Filing) provisions
• Most cost-effective for frequent importers

Best For:

Companies importing more than 2-3 times per year, or those with unpredictable import volumes. Recommended for almost all commercial importers.

Single-Entry Bond (Single Transaction Bond)

A single-entry bond covers only one specific import transaction or shipment. Once the entry is liquidated (finalized) by CBP, the bond expires.

Coverage & Limitations:

• Covers one shipment only
• Must obtain new bond for each import
• Bond amount based on shipment value
• Typically more expensive per shipment
• Expires after entry liquidation
• Does not cover ISF filing

Best For:

One-time or very infrequent importers (less than once or twice per year) with predictable, specific shipments.

For most businesses, a continuous bond is the clear winner. Here's a detailed comparison:

Cost Comparison Example

Decision Matrix

The cost of a customs bond depends on the type of bond, the bond amount required, and your company's financial profile. A common continuous bond amount is $50,000, and current pricing at that level generally runs $400 to $700 per year. A small importer with clean credit usually lands in the $400s to low $500s.

These are current market ranges, not a quote — premium is underwritten on your individual profile and moves with the surety market.

Two things move that number. Multi-year billing — one, two, three and five-year terms are common — lowers the effective annual cost. And underwriting depth scales with the bond: approval on a $50,000 bond is routine, roughly 24 to 48 hours with a business name, EIN and a credit check, while bonds above $500,000 typically call for two to three years of financial statements.

Factors Affecting Bond Costs

Obtaining a customs bond is straightforward and typically takes 1-3 business days. Here's the step-by-step bond application process:

1. 1

   Choose a Surety Provider

   You have three main options for obtaining a customs bond:

   • Customs Broker: Most customs brokers offer bonds through partner surety companies (easiest option)
   • Surety Company: Directly from a surety company that specializes in customs bonds
   • Insurance Agency: Some insurance agencies offer customs bonds as part of their services
2. 2

   Complete the Application

   You'll need to provide:

   • Business name and address
   • EIN (Employer Identification Number)
   • Estimated annual import value
   • Types of products you'll import
   • Countries of origin
   • Personal/business financial information
   • Credit authorization
3. 3

   Underwriting & Approval

   The surety company evaluates your creditworthiness and approves your application. This typically takes 1-3 business days. You may be asked for additional financial documentation for high bond amounts.
4. 4

   Pay the Premium

   Once approved, pay your annual premium (or per-bond fee for single-entry). Payment methods typically include check, ACH, or credit card.
5. 5

   Bond is Filed with CBP

   The surety company files your bond electronically with CBP. You'll receive a bond number and documentation. CBP typically activates the bond within 24-48 hours.
6. 6

   Provide Bond Info to Your Broker

   Give your bond number and surety information to your customs broker so they can reference it when filing your entries. Keep a copy of your bond for your records.

Determining the correct bond amount is crucial. Too low, and your bond won't be accepted; too high, and you'll pay unnecessary premiums.

Continuous Bond Amount Formula

Bond Amount = 10% × (Duties + Taxes + Fees Paid to CBP in the Previous 12 Months)

Rounded up, with a $50,000 minimum

What goes into the 10%

The base is everything you paid to CBP — regular duties, Section 301, Section 232 and IEEPA duties, Merchandise Processing Fee, Harbor Maintenance Fee, excise taxes, and AD/CVD cash deposits.

It does not include broker fees or freight, which aren't CBP-assessed. And the entered value of your goods doesn't factor into a continuous bond calculation at all — only what you paid.

How the amount gets rounded

Continuous bonds are written in fixed increments: multiples of $10,000 up to a $100,000 bond, then multiples of $100,000 above that. Round up — it's the only direction that protects you from an insufficiency notice.

• $225,000 in duties, taxes and fees → 10% = $22,500:

  $50,000 (floor applies)

• $740,000 → 10% = $74,000:

  $80,000

• $12,400,000 → 10% = $1,240,000:

  $1,300,000

Which 12 months?

Worth knowing, because the answer isn't the same in both directions. Bond applications are sized on the calendar year preceding the application, but CBP's sufficiency monitoring runs against a rolling trailing 12 months — an automated review that compares what you've paid against your bond's penal sum and issues an insufficiency notice without a phone call first. Most brokers size the bond on the greater of your trailing or projected 12 months for exactly that reason.

Single-Entry Bond Amount Formula

There are two formulas here, and which one applies depends on what you're importing — not on how you file. Getting this wrong in either direction is expensive: too low and CBP rejects the entry, too high and you're paying premium on three times the coverage you need.

The general rule

Single-Entry Bond = Entered Value + Duties + Taxes + Fees

This is the ordinary commercial shipment — the bond is written for not less than this total

Example Calculation:

• Entered value:

  $15,000

• Duties, taxes and fees:

  $1,850

• Required bond amount:

  $16,850

The 3x exception

Single-Entry Bond = Entered Value × 3

For defined categories where a failure to redeliver creates public health or safety exposure — plus quota

Merchandise that triggers the 3x rule:

• FDA — all regulated merchandise
• EPA — all regulated merchandise
• FCC — all regulated merchandise
• TSCA — all regulated merchandise
• BATF — alcoholic beverages and distilled spirits
• CPSC — toys and fireworks, if sampled for testing
• USDA/AMS — goods subject to marketing orders
• All merchandise subject to quota and/or visa requirements

Three cases that follow neither formula

Mixed entries. If only part of the shipment falls into the categories above, CBP may set the bond at three times the entered value of the qualifying portion, plus entered value and duties, taxes and fees on the remainder.

AD/CVD merchandise. Sized off potential antidumping and countervailing duty liability, not the general rule.

Unconditionally free merchandise. Where goods are unconditionally free of duty and fall outside the categories above, there's a rarely-used option of 10% of the total entered value.

Special Situations

• First-Time Importers

  With no trailing 12 months to calculate against, you're sized on estimated duties, taxes and fees for the coming year, provided the estimate is credible. In practice that lands most first-time importers on the $50,000 minimum, and CBP may increase it based on your projected volume.

• High-Volume Importers

  If your 10% calculation exceeds $50,000, you must maintain a bond at that higher level. This is the number to watch right now — the formula hasn't changed, but duty bills have, and importers who have sat comfortably on the $50,000 minimum for years are being bumped as Section 301, 232 and IEEPA duties stack into the base. CBP's monitoring is automated and issues an insufficiency notice without a call first.

• Special Products

  Products subject to quotas, antidumping/countervailing duties, or certain regulations may require higher bond amounts. Consult with CBP or your broker.

• Low-Duty Importers

  If little or no duty is involved and CBP considers $50,000 inadequate for your activity, there's an alternative basis: one-half of one percent of the value of your importations over an annual period.
