Customs Bond
A customs bond is a financial guarantee to U.S. Customs and Border Protection (CBP) that an importer will pay all duties, taxes, and fees owed on imported goods. It is required for any commercial import valued over $2,500 and for all goods subject to federal regulations, regardless of value.
Types of Customs Bonds
Single-Entry Bond
Covers one import shipment only. Used by businesses that import infrequently (fewer than a few times per year).
- Amount: Typically the value of the goods + applicable duties + taxes
- Cost: Usually 1-5% of the bond amount per transaction
- Best for: Occasional importers, one-time purchases, or sample shipments
Continuous Bond
Covers all imports for a 12-month period. Required if you import frequently and far more cost-effective than multiple single-entry bonds.
- Amount: Minimum $50,000, or 10% of total duties paid in the prior 12 months (whichever is greater)
- Cost: Typically $500-2,000 per year for a standard $50,000 bond (rates vary by risk profile)
- Best for: Regular importers, businesses with ongoing supply chains
How Customs Bonds Work
The Three Parties
- Principal (you, the importer): Obligated to pay duties and comply with customs laws
- Surety (a bonding company): Guarantees payment to CBP if you don't pay
- Obligee (CBP): The government agency that requires the bond
What the Bond Covers
- All customs duties, tariffs, and fees
- Antidumping and countervailing duties
- Any penalties for non-compliance
- Taxes (harbor maintenance tax, merchandise processing fee)
- Redelivery obligations (if CBP orders goods returned)
What Happens If You Default
If you fail to pay duties or violate customs regulations:
- CBP makes a claim against your bond
- The surety pays CBP on your behalf
- The surety then pursues you for reimbursement
- Your ability to obtain future bonds may be impaired
Customs Bonds in the 2026 Tariff Environment
Higher Tariffs = Higher Bond Requirements
With tariff rates at historic highs, continuous bond amounts may need to increase:
Before (2024): Importing $1M/year in goods with 5% average duties = $50,000 in annual duties → minimum $50,000 bond (meets the $50K floor)
After (2026): Same $1M in goods with 40% average duties = $400,000 in annual duties → required $50,000 bond may be insufficient → CBP may require bond increase to $40,000+ (10% of duties)
CBP can demand a bond sufficiency review and require increased bond amounts when tariff changes significantly increase your duty obligations. Several surety companies have reported a surge in bond increase requests since the tariff escalation began.
Impact on Working Capital
Higher bond requirements tie up more capital:
- Surety companies may require collateral for larger bonds
- Bond premiums increase with higher bond amounts
- Some importers with poor credit or high-risk profiles face premium rates of 5-15% of the bond amount
IEEPA Refund Complications
Importers who had bonds drawn against for IEEPA duties are in a complex situation. The bond claims were valid at the time, but the underlying tariff authority has been struck down. Whether bond claims can be reversed as part of the reliquidation process is still being resolved.
How to Get a Customs Bond
- Choose a licensed customs broker — Most brokers can arrange bonds through their surety relationships
- Provide financial information — The surety evaluates your creditworthiness and import volume
- Select bond type — Single-entry or continuous, based on your import frequency
- Set the amount — Minimum $50,000 for continuous bonds; may need more if duties are high
- Pay the premium — Annual premium for continuous bonds; per-transaction for single-entry
Common Mistakes
- Underbonded: If your bond amount doesn't cover your actual duty obligations, CBP can hold your shipments until the bond is increased
- Lapsed bond: Letting a continuous bond expire means your shipments will be held at the port
- Not adjusting for tariff changes: When new tariffs are imposed, review your bond sufficiency immediately
