📄

Single Entry Bond (STB)

Covers one import transaction. Bond amount equals the entered value plus all duties, taxes, and fees. Best for importers making fewer than 3–4 entries per year. Premium is typically a flat $50–$250.

🔄

Continuous Bond (Annual)

Covers all import entries for 12 months. Minimum $50,000 or 10% of prior year's duties. Required for ISF (10+2) filing. Annual premium typically 1–8% of bond amount based on credit and risk.

🏦

Surety Companies

Customs bonds are underwritten by Treasury-approved surety companies. The premium you pay is a fraction of the bond face value — similar to an insurance premium. Your credit score and import history affect your rate.

⚖️

CBP Requirements (19 CFR 113)

All commercial imports over $2,500 require a customs bond. Bonds guarantee payment of duties, taxes, and compliance with CBP regulations. Failure to maintain an adequate bond can result in shipment holds.

Frequently Asked Questions

Common questions about customs bonds and import requirements

How much does a customs bond cost?

A single entry customs bond premium typically costs $50–$250 per entry, depending on the bond amount. A continuous (annual) customs bond premium ranges from $400–$2,500+ per year for the standard $50,000 minimum bond. The premium is what you pay the surety company — not the full face value of the bond. Factors affecting premium cost include your credit score, import history, bond amount, and the surety company you use.

What is the minimum customs bond amount?

For a single entry bond, the minimum bond amount is typically $100 or the value of goods plus duties, taxes, and fees — whichever is greater. For a continuous bond, the minimum is $50,000, or 10% of the total duties, taxes, and fees paid in the prior 12 months — whichever is greater. CBP may require higher bond amounts for importers with compliance issues.

What is the difference between a single entry bond and a continuous bond?

A single entry bond covers one import transaction and expires after that entry is liquidated. A continuous bond (also called an annual bond) covers all import entries for a 12-month period and automatically renews. A continuous bond is required for ISF (10+2) filing. Most importers who make more than 3–4 entries per year save money with a continuous bond.

Who needs a customs bond?

Any person or business importing commercial goods into the United States valued over $2,500 is required to have a customs bond (19 CFR 113). This includes importers of record, licensed customs brokers, international carriers, and Foreign Trade Zone operators. Even shipments under $2,500 require a bond if they are subject to AD/CVD orders or other agency requirements.

When should I switch from single entry to continuous bond?

The break-even point depends on your shipment values and the surety premium rates you qualify for. As a general rule, if you make 4 or more import entries per year, a continuous bond is usually more cost-effective. Beyond cost savings, a continuous bond is also required for ISF filings and provides operational convenience — no need to arrange a new bond for each shipment.

What is the Merchandise Processing Fee (MPF)?

The Merchandise Processing Fee (MPF) is a CBP fee charged on all formal entries at a rate of 0.3464% of the entered value, with a minimum of $31.67 and a maximum of $614.35 per entry. MPF is included in the bond amount calculation because the bond must cover all duties, taxes, and fees associated with the import entry.
