US import tariff rates for South Korea-origin electronics in 2026. Covers Samsung memory/OLED, SK Hynix DRAM/HBM, LG Display, and relevant HTS codes.
The US-Korea Free Trade Agreement (KORUS FTA, effective 2012) eliminated most tariffs on electronics between the US and South Korea. However, the Section 122 global surcharge (10%, effective February 2026) is applied regardless of FTA status for non-USMCA countries. Korean electronics therefore face 0% MFN (under KORUS) + 10% Section 122 for most electronic components. No Section 301 applies to Korea.
Samsung Electronics manufactures DRAM and NAND at its Korean fabs (Hwaseong, Pyeongtaek). Korean-origin Samsung memory uses HTS 8542.32 at Free MFN (KORUS) + 10% Section 122. Samsung's OLED display panels — widely used in premium smartphones and monitors — use HTS 8524.12 (active matrix OLED) at 0% MFN + 10% Section 122. Samsung also produces memory in China (Xi'an) which would face 60% duty — buyers should verify origin.
SK Hynix produces cutting-edge DRAM including HBM3/HBM3E high-bandwidth memory for AI accelerators (Nvidia H100/H200 use SK Hynix HBM). All SK Hynix production is Korea-origin. HBM is classified under HTS 8542.32 at Free MFN (KORUS) + 10% Section 122. Given that a single HBM3E stack costs ~$100–200, the 10% surcharge adds $10–20 per stack — meaningful for data center purchases.
LG Display and Samsung Display are the world's dominant OLED panel manufacturers. Large OLED panels (TV-size, HTS 8524.12 or 8528.52 for assembled monitors) from Korea face 0% MFN + 10% Section 122. Before Section 122, OLED panels from Korea entered duty-free under KORUS. The 10% surcharge represents a new cost that display brands must absorb or pass to consumers.
No. Section 122 is applied under executive authority (19 U.S.C. § 2132) and is separate from FTA tariff schedules. KORUS reduced MFN rates to 0% for most electronics, but the Section 122 surcharge still applies. Only USMCA (Mexico and Canada) are explicitly exempt from Section 122.
Samsung DRAM (HTS 8542.32) from South Korea: 0% MFN under KORUS + 10% Section 122 = 10% total. For Samsung DRAM manufactured in China (Xi'an facility): 0% MFN + 50% Section 301 + 10% Section 122 = 60% total. Always verify country of origin with your supplier.
No. Section 301 applies only to China-origin goods. Korean-manufactured LG OLED TVs face the 10% Section 122 surcharge. Note that some LG products are assembled in China or Mexico — country of origin determines which tariff applies.
HBM is a form of DRAM (HTS 8542.32). Korea-origin HBM from SK Hynix: 0% MFN + 10% Section 122 = 10% total duty.
