Understanding Customs Bonds

A customs bond is a financial guarantee that ensures duties, taxes, and fees will be paid and import regulations followed. Most commercial importers need one.

What Is a Customs Bond?

A three-party agreement:

  • Principal: The importer who must fulfill obligations
  • Surety: Insurance company backing the bond
  • Beneficiary: CBP (US Customs and Border Protection)

When Is a Bond Required?

  • Commercial shipments valued over $2,500
  • Goods subject to other agency requirements (FDA, etc.)
  • Quota merchandise
  • Temporary imports

Types of Customs Bonds

Single Entry Bond (STB)

  • Covers one specific shipment
  • Valid for that entry only
  • Good for occasional importers
  • Cost: typically 0.5-1% of shipment value + duties
  • Minimum coverage amount applies

Continuous Bond (CB)

  • Covers all entries for one year
  • Renewed annually
  • Required amount: greater of $50,000 or 10% of prior year's duties
  • Cost: typically $500-2,000+ per year
  • More economical for regular importers

Bond Amount Calculation

Continuous Bond:

  • 10% of duties, taxes, and fees paid in prior year
  • Minimum $50,000
  • CBP may require higher amounts based on risk

Single Entry:

  • Total entered value + duties + taxes + fees
  • Minimum typically $100

How to Obtain a Bond

  1. Contact a surety company or customs broker
  2. Complete application with business information
  3. Provide financial documentation if required
  4. Pay premium
  5. Bond filed with CBP

Bond Sufficiency

CBP monitors bond adequacy:

  • Periodic reviews of duty levels vs bond amount
  • May require bond increase if importing more
  • Insufficient bond can cause shipment delays

Bond Claims

CBP can make claims against your bond for:

  • Unpaid duties or fees
  • Liquidated damages for violations
  • Penalties for non-compliance

Impact of Claims:

  • Surety pays CBP
  • Surety seeks reimbursement from you
  • May affect future bond availability or cost
  • Multiple claims can make bonding difficult

Activity Codes

Bonds cover specific activities:

  • Code 1: Importer/broker (most common)
  • Code 2: Drawback
  • Code 3: Custodian of bonded merchandise
  • Other codes for specialized activities

Best Practices

  • Get continuous bond if importing more than a few times per year
  • Review bond sufficiency annually
  • Maintain good compliance to protect bond standing
  • Work with reputable surety companies
