Import duty rates for heading 28.33 from Japan's official tariff schedule. Which column applies? Most imports take the WTO rate (or General/Temporary where shown, if lower); GSP/LDC are preferential rates for developing countries; EPA rates (inside each row) apply when your goods qualify under that agreement's rules of origin. Rows without a percentage rate (specific, compound, seasonal or quota rates) need case-by-case review. Use the Calc button for the landed-cost estimate.
