Trade math before the shipment moves
Landed-cost tools that feel closer to an import desk than a toy calculator.
Model duty, VAT, freight, brokerage, low-value threshold behavior, and per-unit landed cost in one place. The point is not just the number, it is the operating decision that follows it.
Main planner
Run the first landed-cost pass here.
The presets are meant to get the file into the right shape fast. Then you can override the rate, threshold, and basis assumptions with your broker's instructions.
Import duty and landed-cost planner
Enter the shipment economics, then review the threshold note, scenario table, and operating guidance before you lock a quote.

Operational readout
Before you trust the number
- Check whether your supplier quote is FOB, CIF, or DDP before you decide what belongs in the duty base.
- Confirm the HS code and origin claim, especially when the duty rate is high enough to change margin materially.
- Quote two versions when the file is fragile: base assumptions and stressed assumptions.
Entry pages
Multiple ways into the toolkit, without dead SEO pages.
Each page is meant to solve a specific planning task, not just repeat the homepage.
Import duty calculator
Open the tariff-focused version with the same engine and clearer customs-specific framing.
Landed cost calculator
Use the per-unit and total-cost framing when you are quoting, replenishing, or setting margin floors.
How to estimate import duty
Follow the workflow for value basis, low-value lines, HS codes, and rate stress tests.
HS code lookup guide
Use the classification worksheet and broker brief builder before you ask for a final duty answer.
Customs duty calculator
Use the clearance-first route when brokerage, customs value, and broker handoff are the main concern.
US import duty calculator
Open the US-specific view with conservative threshold logic and no federal import VAT in the starter model.
UK import duty calculator
Use the UK-specific route when the GBP 135 customs-duty line and VAT treatment shape the decision.
De minimis calculator
Model low-value threshold behavior directly when a relief assumption might change the whole file.
Use cases
Built around operational decisions.
Stop underpricing landed goods.
Use the per-unit result and stressed scenarios before you hand a customer or channel partner a number you cannot defend later.
Compare consolidation versus frequent small files.
Brokerage, disbursement, and FX friction often matter more than the headline tariff line on smaller consignments.
Surface the questions that still need a broker.
When the model is fragile, the answer is not another calculator. It is better classification evidence and a clearer declaration basis.
FAQ
Common planning questions
Is this legal or broker advice?
No. It is a planning tool. Use it to shape a realistic landed-cost model, then confirm the final filing logic, HS classification, origin claim, and rate treatment with your broker or customs specialist.
Why is threshold logic separated from duty and tax?
Because low-value relief is not one universal thing. Some markets waive duty but still collect VAT, while others can shift the tax collection point or remove both. The model makes that assumption visible.
Why include brokerage and an FX buffer?
Because teams often miss the non-duty friction. A quote can look workable on tariff alone and still fail after disbursement, broker charges, and currency slippage show up.
