Formal Entry Fee Calculator: Estimate MPF, Bond, and Customs Costs
Estimate the extra costs that appear when a US import becomes a formal entry, including MPF, bond, broker, and tariff stack checks.
Formal entry changes the cost model
Many importers focus only on the $2,500 threshold. The operational question is bigger: once a shipment is treated as a formal entry, you need a more complete cost model with MPF, possible bond cost, classification accuracy, and broker filing work.
If you know your product and origin, run the TariffCheck import calculator. If you are deciding whether a shipment crosses into formal-entry planning, use the checklist below.
Formal entry cost components
| Component | Why it matters |
|---|---|
| HTS duty | The base customs duty rate depends on classification |
| Section 301 or other additional duties | Can apply to China-origin goods and other covered categories |
| MPF | Formal entries generally use the percentage formula with min/max |
| Bond | Formal entries typically need a single-entry or continuous bond |
| Broker filing | Many importers use a broker for formal entries |
| HMF | Add for qualifying ocean cargo |
Quick estimate workflow
- Confirm entered value and shipment type.
- Identify the HTS code.
- Apply HTS duty and any origin-specific tariff layer.
- Add MPF.
- Add bond and broker estimate.
- Add HMF if ocean cargo.
Practical rule
Do not compare informal and formal entry using duty alone. Formal entry affects paperwork, bond requirements, processing fees, and misclassification risk.
Is formal entry always more expensive?
Usually it has more line items, but it may be the correct or required path for higher-value commercial imports. The cost model should include both compliance and fees.
