How to use this tool
Use this calculator when you already know the item price and a rough shipping cost.
What to enter
- Item price in KRW.
- Shipping cost in KRW.
- Your working duty-free threshold.
- Duty rate and VAT rate if you know the product category.
What the result means
The tool estimates three core numbers:
- Declared value.
- Estimated duty.
- Estimated VAT and total landed cost.
This is useful when a Korean order looks cheap at checkout but becomes less attractive after customs fees.
Practical notes
- The result is a planning estimate, not an official customs quote.
- Some categories use different duty logic.
- If you are unsure, use a slightly conservative duty rate so you do not under-budget.
Best use case
Use this before placing an order for beauty, electronics, supplements, or any item where customs cost can change the decision.
