Customs Bonds Explained: Types, Costs, and How to Get One (2026)

# Customs Bonds Explained: Types, Costs, and How to Get One (2026)

A customs bond is one of the first things you need before importing commercial goods into the United States — and one of the least understood. It is a financial guarantee filed with U.S. Customs and Border Protection (CBP) that ensures all duties, taxes, and fees owed on an import shipment will be paid, even if the importer fails to pay.

If you import goods valued over $2,500, you need a customs bond. There are no exceptions for small businesses, first-time importers, or low-risk products. And in 2026, with Section 122 surcharges, restructured Section 232 duties on steel and aluminum, and elevated Section 301 tariffs on Chinese goods, understanding your bond — and whether it is sized correctly — is more important than ever.

This guide covers how customs bonds work, the two types available, what they cost, and why 2026's tariff environment may require you to increase your bond amount.

What Is a Customs Bond?

A customs bond is a three-party contract between the importer (the principal), CBP (the obligee), and a surety company (the guarantor). The surety company — which must be approved by the U.S. Department of the Treasury — guarantees that the importer will comply with all CBP regulations, including payment of duties and taxes.

Think of it like an insurance policy that protects the U.S. government. If an importer fails to pay duties, CBP collects from the surety, and the surety then seeks reimbursement from the importer.

Customs bonds are governed by 19 CFR Part 113 and authorized under 19 U.S.C. Section 1623. CBP's electronic bond system (eBond) processes all bond filings.

When Do You Need a Customs Bond?

You are required to have a customs bond for any of the following:

- Commercial imports over $2,500 — any goods imported for resale, manufacturing, or commercial use - Regulated goods at any value — imports subject to FDA, USDA, EPA, or CPSC oversight - Quota-class merchandise — regardless of declared value - Any formal customs entry — entries processed through the formal entry system

If you are importing personal goods under $2,500, you may use an informal entry and bypass the bond requirement. But for any commercial import activity, a bond is mandatory.

Types of Customs Bonds

There are two types of customs bonds, and choosing the right one depends on how frequently you import.

Single Entry Bond (SEB)

A single entry bond covers one import shipment. It is purchased per transaction and expires once CBP liquidates the entry — typically 10 to 12 months after import. Single entry bonds are best for:

- Businesses that import fewer than three or four times per year - One-time purchases or sample shipments - Importers testing a new product line before committing to regular imports

The bond amount for a single entry bond must equal the entered value of the goods plus all applicable duties, taxes, and fees. For example, if you are importing $40,000 worth of steel products from China subject to 25% Section 301 duties, 50% Section 232 duties, and 10% Section 122 surcharges, your total duty obligation is $34,000 — so the bond amount must be at least $74,000 (goods value plus duties).

Continuous Bond (CB)

A continuous bond covers unlimited entries for a 12-month period and automatically renews. It is the standard choice for regular importers. Continuous bonds are best for:

- Businesses importing more than three or four times per year - Companies with predictable import volumes - Any importer who wants to avoid purchasing a new bond for every shipment

The minimum continuous bond amount is $50,000. CBP calculates the required amount as 10% of the total duties, taxes, and fees paid in the prior 12 months, rounded up to the nearest $10,000 — with a floor of $50,000. If your annual duty payments total $600,000, for example, your bond must be at least $60,000.

How Much Do Customs Bonds Cost?

The cost of a customs bond is the premium you pay to the surety company — not the bond amount itself. You are not paying $50,000 for a continuous bond; you are paying a premium that typically runs between 0.5% and 2% of the bond amount.

Single Entry Bond Premiums

| Bond Amount | Typical Premium | |---|---| | Under $10,000 | $50 – $75 | | $10,000 – $50,000 | $75 – $125 | | $50,000 – $100,000 | $100 – $200 | | $100,000 – $500,000 | $150 – $400 | | Over $500,000 | $300 – $600+ |

Most surety companies charge a minimum premium of around $50 per single entry bond.

Continuous Bond Annual Premiums

| Bond Amount | Annual Premium | |---|---| | $50,000 (standard minimum) | $400 – $600 | | $100,000 | $600 – $1,200 | | $250,000 | $900 – $1,500 | | $500,000 | $1,200 – $2,000 | | Over $1,000,000 | $1,500 – $5,000+ |

Minimum annual premiums are typically around $400.

What Affects Your Premium

Premiums vary based on the importer's credit history and financial strength, the types of goods being imported (regulated or high-risk products carry higher premiums), import volume and compliance history with CBP, and whether antidumping or countervailing duties (AD/CVD) apply to your products.

How to Get a Customs Bond

The process is straightforward and typically takes two to seven business days:

Step 1: Determine your bond type. Single entry for occasional imports, continuous for regular activity. If you import more than 3–4 times per year, a continuous bond is almost always more cost-effective.

Step 2: Choose a Treasury-approved surety provider. Your customs broker can arrange this, or you can apply directly through surety companies like Roanoke Trade, Avalon Risk Management, or JW Surety Bonds. The full list of Treasury-approved sureties is publicly available.

Step 3: Submit your application with business information including your Employer Identification Number (EIN), CBP importer number, estimated annual import volume, and estimated annual duties.

Step 4: Underwriting. The surety reviews your financials and compliance history. This typically takes 2–5 business days.

Step 5: Bond filing. The bond is filed electronically via CBP's eBond system.

Step 6: Renewal. For continuous bonds, you will receive a renewal notice 60 to 90 days before expiration.

Most customs brokers handle bond procurement as part of their service. If you already work with a broker, ask them to arrange your bond — they deal with surety companies daily and can often secure competitive rates.

Why 2026 Tariffs Mean You Should Re-Check Your Bond

Here is where many importers get caught. Your continuous bond amount is based on 10% of your prior year's duties. But 2026 has introduced significant new duty layers that did not exist in 2025:

- Section 122 added a 10% universal surcharge on most imports effective February 24, 2026 - Section 232 restructured steel and aluminum tariffs to 50% on the full customs value (up from 25% on metal content), effective April 6, 2026 - Section 232 also added copper and copper derivatives to the tariff schedule - Section 301 maritime port fees jumped to $80 per net ton on April 17, 2026 - Section 232 semiconductor tariffs took effect in 2026

If your bond was sized based on 2025 duty payments, it may now be insufficient. An insufficient bond — called a "bond deficiency" — can result in CBP holding your shipments at the port, delays of days or weeks while you obtain a rider or new bond, storage fees at the port accumulating daily, and potential penalties.

CBP monitors bond sufficiency and can issue a notice requiring you to increase your bond amount within 30 days. But do not wait for a notice — proactively calculate your expected 2026 duty obligation and adjust accordingly.

Quick check: if your annual duties increased by more than 25% due to the new tariffs, your bond almost certainly needs to be increased.

Customs Bond vs. Customs Bonded Warehouse

These are different concepts that sometimes confuse importers. A customs bond is a financial guarantee required for importing goods. A customs bonded warehouse is a physical facility where imported goods can be stored without paying duties — duties are only owed when the goods leave the warehouse for domestic consumption. For a full breakdown, see our guide on US Customs Bonded Warehouses.

You need a customs bond to import goods into a bonded warehouse. The warehouse itself operates under a separate Type 2 bond (warehouse proprietor's bond).

Key Takeaways

Every commercial importer bringing goods into the U.S. valued over $2,500 needs a customs bond. For regular importers, a continuous bond at $50,000 minimum is almost always more cost-effective than repeated single entry bonds. Annual premiums typically run $400 to $600 for a standard $50,000 continuous bond. The 2026 tariff increases — particularly Section 122 and restructured Section 232 — mean many importers need to reassess whether their current bond amount is adequate. Your customs broker can help you obtain or adjust your bond quickly.

If you are importing steel, aluminum, copper, or products from China, run the numbers now. The last thing you want is a shipment held at port because your bond was sized for pre-2026 duty rates.
