- Confirm whether the planned transaction is a formal entry or another activity that requires security. Start with the first-time importer checklist when the importer number, broker, or entry type is not settled.
- Build a 12-month shipment forecast with entry count, entered value, country of origin, candidate HTS, customs value, and estimated duties, taxes, and fees.
- Use the Import Duty Calculator for a transparent estimate. Keep base duty, Chapter 99 duties, MPF, HMF, and commercial fees on separate lines.
- Mark regulated merchandise and trade-remedy exposure. Ask the broker or surety whether a higher single-transaction amount, collateral, or other requirement applies.
- Compare the expected total cost and operating burden of repeated single-entry bonds with one continuous bond. Include premiums, processing time, collateral, and shipment delay risk.
- For ocean shipments, confirm how the ISF obligation will be secured and who will file. Read the ISF 10+2 preparation guide before cargo is booked.
- Obtain a written quote from a customs broker acting for a surety or from a Treasury-authorized surety. Confirm the bond activity, amount, importer number, effective date, and renewal or cancellation terms.
- Save the forecast, quote, bond form, approval, and review date. Revisit the amount before the next bond year or sooner when exposure changes.

Single-Entry vs Continuous Customs Bond: A US Importer Decision Guide
Compare single-entry and continuous US customs bonds using shipment frequency, entered value, duties, taxes, fees, agency requirements, ISF needs, and the importer's 12-month entry plan.
Answer Summary
Preparation checklist
A customs bond is a financial guarantee to CBP, not an insurance policy that transfers the importer's compliance responsibility.
CBP describes a single-entry bond as coverage for one import shipment and a continuous bond as coverage for import transactions during a 12-month period.
Bond amount and premium are different. CBP rules determine the required coverage; a surety or broker quotes the commercial premium and may request underwriting information.
Regulated merchandise, AD/CVD exposure, ISF coverage, and changing import volume can make a simple shipment-count comparison incomplete.

Required fields or decision table
Fields to prepare before the document draft
| Field or decision | What to prepare |
|---|---|
| Importer and activity | Record the importer number, legal entity, entry activity, broker or filer, expected ports, and whether the bond must support only entry activity or another customs activity. |
| Twelve-month entry plan | Estimate shipment count, entered value, customs value, duties, taxes, and fees across the coming 12 months. Keep low, expected, and high cases rather than one optimistic number. |
| Single-entry coverage basis | For an ordinary activity-code-1 entry, CBP guidance generally starts with entered value plus applicable duties, taxes, and fees. Certain regulated merchandise or special risks can require greater security. |
| Continuous coverage basis | CBP guidance states that an activity-code-1 continuous bond is generally based on 10% of duties, taxes, and fees over a 12-month period, subject to the applicable minimum and CBP or surety requirements. |
| Product and agency risk | Identify FDA, USDA, EPA, CPSC, FCC, quota, AD/CVD, or other agency and trade-remedy issues. Do not assume the ordinary formula is the final amount for restricted merchandise. |
| Ocean ISF relationship | Confirm whether the continuous bond will secure ISF obligations or whether a separate ISF bond arrangement is needed. An entry bond decision and an ISF filing decision are related but not identical. |
| Underwriting and timing | Ask the broker or Treasury-listed surety for premium, collateral, application documents, effective date, cancellation terms, and lead time. A bond amount is not the same as its price. |
| Review trigger | Recalculate after a material increase in volume, duty exposure, AD/CVD risk, regulated goods, importer entity, or when CBP or the surety requests additional security. |
Step-by-step preparation
How to prepare the draft
Ecommerce example
How this looks in a seller workflow
A US marketplace seller plans one trial ocean shipment, then monthly replenishment if the product succeeds. The first shipment has a modest entered value, but the product may also carry an additional tariff and requires an ISF.
The seller should not compare only the advertised premium for one bond against one annual quote. The review estimates 12 months of duties, taxes, and fees, identifies the ISF arrangement, asks whether product regulation changes the required security, and compares the operational cost of arranging a bond for every shipment.
If the launch remains genuinely one-off, a single-entry bond may be reasonable. If monthly replenishment is approved, a continuous bond may reduce repeated administration. The broker or surety must still confirm the actual amount and underwriting terms.
- Forecast the full 12-month exposure.
- Separate required bond amount from commercial premium.
- Include additional duties and agency risk.
- Confirm ISF coverage for ocean cargo.
- Save the quote and review trigger.
Verification checklist
Review the record before it enters a shipment or filing workflow
- The importer legal entity and importer number match the bond application.
- The entry type and covered customs activity are identified.
- The forecast includes duties, taxes, and fees rather than merchandise value alone.
- Additional tariffs and AD/CVD risk have not been omitted.
- Regulated merchandise has been disclosed to the broker or surety.
- ISF security has been addressed for ocean shipments.
- Premium, collateral, effective date, and cancellation terms are written down.
- A volume or exposure threshold triggers a new review.

Common mistakes
What to avoid
- Choosing by premium alone without checking required coverage.
- Treating the bond as insurance against incorrect classification, value, or origin.
- Omitting Section 301, Section 232, AD/CVD, or other additional duty exposure.
- Using ship-from country instead of manufacturing origin in the estimate.
- Assuming an entry bond automatically solves every ISF bond question.
- Using last year's import volume after the product mix or duty exposure changed.
- Buying a bond for the wrong importer number or legal entity.
- Hardcoding a bond amount without confirmation from current CBP guidance and the surety.

FAQ
Common questions
What is the difference between a single-entry and continuous customs bond?
A single-entry bond covers one transaction; a continuous bond generally covers qualifying customs transactions for 12 months.
What is the minimum continuous customs bond amount?
CBP currently describes $50,000 as the general minimum for an activity-code-1 continuous importer bond, but the required amount can be higher. Verify the current rule for the activity and exposure.
How is a single-entry customs bond amount calculated?
CBP guidance generally starts with entered value plus duties, taxes, and fees for an ordinary single transaction, while certain merchandise can require more security.
Is the bond amount the price I pay?
No. The bond amount is the limit of liability. The surety or broker separately quotes the premium and may require collateral.
Does a customs bond cover an ISF filing?
It can, depending on the bond activity and filing arrangement. Confirm whether the bond secures both entry and ISF obligations or whether separate security is needed.
Can a customs broker obtain the bond for me?
Yes. A licensed customs broker commonly acts as agent for a surety, or the importer can work with a Treasury-authorized surety.
When should a continuous bond be reviewed?
Review it before renewal and whenever duties, taxes, fees, regulated merchandise, AD/CVD exposure, product mix, volume, or importer identity changes materially.
