US Import Duty & Landed Cost Calculator
Enter a product or HTS code, country of origin, quantity, unit price, entry date, and transport mode. The calculator estimates represented base duty, additional tariff layers, selected MPF treatment, HMF, and landed cost, with each line's assumptions and official sources visible. It does not determine the legally correct classification, entry type, or final amount assessed by CBP.

Turn a one-off estimate into a catalog workflow.
SkuWatch links HTS classifications to changing measures and source history. Save a scenario locally after calculating to rerun its inputs against current data.
How it works
One estimate, with every assumption kept visible.
Set the origin
The same HTS line can have a different stack by origin. FTA preference is modeled separately from ordinary origin.
Describe the shipment
Quantity, price, transport, freight, and insurance make the estimate useful for a purchase decision.
Inspect the stack
Base rate, additional measures, fees, match quality, and authority links remain separate—never hidden inside one percentage.
Public worked examples
Inspect the facts and arithmetic before rerunning them.
Automatic drip coffee maker from China
One precisely specified appliance, a dated $100 U.S. import scenario, separate duty layers, and live exclusion boundaries.

A construction-specific candidate line, current represented stack, and textile, origin, and admissibility stops.

Why Canadian dispatch does not replace the origin of an unchanged China-made appliance entering the U.S.
Read the example →What the estimate covers
Tariff layers are calculated independently.
The engine uses only current, structured rules represented in the SkuWatch snapshot. It flags the categories that still require broker or agency review.
Base HTS duty
General rate, including clean ad valorem, specific, and compound rate forms where the required unit is supported.
Section 301
Current origin-and-code layers from USTR-linked records, shown separately from the base rate.
Section 232
Current product measures represented in the structured rule set, with their source authority.
FTA scenario
Uses the HTS special rate only where the listed program matches the origin. Eligibility is not assumed.
CBP user fees
FY2026 formal-entry MPF and ocean HMF, with the fee schedule’s validity date enforced.
Review flags
AD/CVD, exclusions, quota treatment, ambiguous units, and classification uncertainty are disclosed rather than guessed.
Built for decisions
From purchase order to product catalog.
The same transparent calculation serves four different jobs without changing the underlying record.
Importers & brands
Test landed cost and margin before committing to a supplier or origin.
3PLs & brokers
Give clients a traceable first estimate and surface the assumptions that need validation.
Developers
Prototype tariff-aware checkout, sourcing, ERP, and catalog workflows against structured records.
Finance & operations
Compare planned costs with entry documents and identify where the tariff stack changed.
Data status
Freshness is part of the answer.
Every calculation is tied to a named HTS revision and the current structured measure snapshot. A stale fee schedule is automatically withheld instead of silently reused.

Common questions
Know what the estimate does—and does not—prove.
Does the calculator choose the legally correct HTS code?
No. Product search produces classification candidates from the current HTS text; it is not a binding classification. Confirm the full 10-digit code from the product facts and, where needed, request professional or CBP guidance.
What customs value does SkuWatch use?
The calculator uses quantity × price per unit as the goods value for duty and the FY2026 MPF scenario. Freight and insurance remain visible in landed cost but are not included in that customs-value assumption.
Does selecting an FTA country guarantee a special rate?
No. The option is an explicit scenario. It uses a listed special-program rate only when the HTS record names a program matching the selected origin. Rules of origin, documentation, direct shipment, and other requirements still need validation.
Are MPF and HMF always charged?
No. Choose the MPF entry treatment that matches the filing. Formal and informal entries use different FY2026 amounts. HMF is a separate scenario for qualifying commercial vessel cargo at a covered U.S. port; transport mode alone does not establish that it applies.
Are AD/CVD cash-deposit rates included?
Not yet. AD/CVD scope and respondent-specific rates can require facts beyond an HTS code and country. SkuWatch flags this review boundary rather than inserting a generic percentage.
