How Import Duty and VAT Are Calculated

Oct 21, 2025 · 5 min read · Capra Logistics

Getting an accurate landed cost means knowing the order and basis on which duty and VAT are actually calculated. The concepts aren't hard, but getting the sequence wrong can throw your estimate off significantly.

1. CIF is the starting point

Duty isn't calculated on the goods' price alone. It's based on the CIF value: Cost + Insurance + Freight combined. If you only have an FOB price, you'll need to add freight and insurance to arrive at CIF first.

2. Duty = CIF × duty rate

Duty = CIF value × duty rate (%)

The duty rate depends on the product's HS code, and can be reduced, sometimes to 0%, under an FTA (e.g., Korea-EU, Korea-US) if you have a valid certificate of origin.

3. VAT is calculated on CIF plus duty

VAT = (CIF value + Duty) × VAT rate (10%)

Here's where estimates commonly go wrong. VAT isn't applied to the CIF value alone. It's applied to CIF + duty (the tax base). Forgetting to add the duty first will understate your VAT.

4. A worked example

Say your CIF value is ₩10,000,000 and the duty rate is 8%. Duty = ₩10,000,000 × 8% = ₩800,000. VAT = (₩10,000,000 + ₩800,000) × 10% = ₩1,080,000. Total estimated tax is ₩1,880,000, and total landed cost (CIF + tax) comes to roughly ₩11,880,000.
