Japan vs South Korea: Import Tariff Comparison 2026

Both Japan and South Korea have bilateral trade agreements with the United States, but at different negotiated rates — 15% for Japan and 15% for South Korea. These bilateral deals replace the standard Section 122 global surcharge, giving these trading partners differentiated tariff treatment compared to countries without formal agreements. For importers of consumer electronics, the total effective rate from Japan is 16.5% while South Korea comes in at 16.5%. The bilateral frameworks provide a degree of rate certainty, though the legal durability of these deals remains subject to ongoing trade policy developments following the February 2026 IEEPA ruling. Both countries represent more predictable tariff environments than non-deal countries that face the uniform Section 122 rate of 15%.

Trade Agreement Status

Japan has a bilateral deal with the US at 15% (replaces the standard Section 122 rate). South Korea has a bilateral deal with the US at 15% (replaces the standard Section 122 rate). For products under Section 232 national security tariffs, the bilateral deal or Section 122 rate does not apply — S232 rates govern instead. China-origin goods additionally face Section 301 tariffs that stack on top of all other duties, making trade agreement status a defining factor in the total tariff burden.

When to Source from Each Country

Japan offers lower tariff rates across all focus product categories in this comparison, making it the more cost-effective sourcing origin from a tariff perspective. Source from South Korea when its supplier relationships, product specialization, or geographic advantages outweigh the tariff cost differential. Always model total landed cost — including freight, insurance, MPF, and HMF fees — before finalizing sourcing decisions.
