Formula Used
1. Dutiable Base
Dutiable Base = Declared Value, or Declared Value + Shipping, or Declared Value + Shipping + Insurance, depending on the selected basis.
2. Effective Tariff Rate
Effective Tariff Rate = max(Base Tariff Rate - Preferential Discount, 0).
3. Duty Amount
Duty Amount = Dutiable Base × Effective Tariff Rate ÷ 100.
4. Anti-Dumping Amount
Anti-Dumping Amount = Dutiable Base × Anti-Dumping Rate ÷ 100.
5. Excise Amount
Excise Amount = (Dutiable Base + Duty Amount + Anti-Dumping Amount) × Excise Rate ÷ 100.
6. VAT Amount
VAT Amount = (Dutiable Base + Duty Amount + Anti-Dumping Amount + Excise Amount + Other Fees) × VAT Rate ÷ 100.
7. Total Landed Cost
Total Landed Cost = Declared Value + Shipping + Insurance + Other Fees + Duty + Anti-Dumping + Excise + VAT.
Use the exchange rate to convert invoice currency values into local currency for pricing, budgeting, and ecommerce margin planning.

FAQs
1. What does this tariff rate calculator estimate?
It estimates duty, anti-dumping charges, excise, VAT, landed cost, per-unit cost, and margin impact from imported ecommerce inventory.
2. What is the difference between FOB, CFR, and CIF?
FOB uses goods value only. CFR adds shipping. CIF adds shipping and insurance. Your customs rules determine which basis applies.
3. Why is there a preferential discount field?
Some imports qualify for reduced duty through trade agreements or origin programs. This field lowers the effective tariff rate for scenario testing.
4. Does this calculator replace customs advice?
No. It is a planning tool for estimates. Product classification, origin rules, and local regulations still require formal verification.
5. Can I use local currency only?
Yes. Enter the same currency code in both fields and use an exchange rate of 1. The calculator will still work correctly.
6. How is margin calculated here?
Margin equals expected revenue minus total landed cost, divided by expected revenue. It shows how tariffs affect pricing power.
7. What should I include in other fees?
Include brokerage, customs processing, inspection charges, documentation fees, terminal handling, port charges, and similar import costs.
8. What files can I export from the result?
You can export the calculated scenario as a CSV file or generate a PDF summary for pricing reviews and records.
