South Korea Tariff Rates 2026: 10% on US Imports
As of 2026-06-14, US imports from South Korea carry an effective tariff of about 10%. This combines the 10% Section 122 baseline applied to all countries. The rate fell from 25% after the Supreme Court struck down the IEEPA tariffs in February 2026, so importers who paid the higher rate between April 2025 and February 2026 may qualify for refunds. Goods qualifying under the KORUS FTA may enter with reduced or zero base duty, though the Section 122 tariff still applies. The 10% Section 122 tariff was ruled unlawful by the Court of International Trade in May 2026, but a Federal Circuit stay is keeping it in force pending appeal; absent that, it is set to expire around July 24, 2026.

South Korea Import Tariff Overview
South Korea saw major tariff relief from the SCOTUS ruling — its IEEPA rate dropped from 25% to the 10% Section 122 tariff. Combined with the KORUS FTA (which eliminates MFN duties on qualifying goods), South Korea is now one of the most cost-effective Asian sourcing origins at $116B in annual US imports.
The KORUS FTA, in effect since 2012, eliminated tariffs on approximately 95% of bilateral trade in goods. The old 25% IEEPA tariff had created an unusually punitive layered structure on top of KORUS preferences. The SCOTUS ruling and shift to 10% Section 122 has restored South Korea's competitive position. South Korea has a Section 232 steel quota arrangement (TRQ) that exempts qualifying steel volumes from the 50% tariff.
Key Products Imported from South Korea
Top imports include semiconductors and display panels, passenger vehicles (Hyundai, Kia, Genesis), auto parts, machinery, organic chemicals, and steel products. South Korea is a critical supplier of memory chips, OLED displays, and EV batteries (Samsung SDI, LG Energy Solution, SK Innovation).
Recent Changes
Feb 20, 2026: SCOTUS struck down IEEPA tariffs — South Korea's rate dropped from 25% to 10% Section 122 (expires ~July 24, 2026). This represents a 15-point reduction and major relief for Korean exporters. Section 232 steel quota arrangement remains. Samsung, LG, SK, and Hyundai continue expanding US manufacturing operations (EV battery gigafactories in Georgia, Tennessee, and Michigan). KORUS FTA is stable.
Tips for Importers
KORUS FTA certificates of origin are now even more valuable — they eliminate MFN duties, leaving only the 10% Section 122 tariff (down from 25% IEEPA). For semiconductors, most enter at 0% MFN, so the tariff burden is just the 10% Section 122. Hyundai, Kia, and Genesis vehicles built in the US (Alabama, Georgia) avoid all import tariffs. Korean steel within the Section 232 TRQ avoids the 50% surcharge. The Section 122 expiry in ~July 2026 could remove the remaining 10% layer.
How Are US Tariffs on South Korea Imports Calculated?
US import duties on goods from South Korea are determined by multiple overlapping tariff authorities. The base layer is the Section 122 tariff at 10%, which applies to all countries and is set to expire around July 24, 2026. (The Court of International Trade ruled this tariff unlawful in May 2026; it remains collected under a Federal Circuit stay while the government’s appeal proceeds.) South Korea benefits from the KORUS FTA, which can eliminate MFN base duties on qualifying goods — though the Section 122 tariff still applies on top of FTA preferences.

Already importing from South Korea? If you paid the higher pre-SCOTUS IEEPA rate in 2025, you may be able to claim an IEEPA tariff refund. And if you re-export or manufacture with imported goods, duty drawback can recover up to 99% of the duties you paid — both are separate from the rates above.
