South Korea vs Taiwan: Import Tariff Comparison 2026
Neither South Korea nor Taiwan carries a negotiated bilateral tariff rate that the United States charges today. The country-specific rates reported through 2025 as bilateral deals were lines inside the reciprocal tariff imposed by Executive Order 14257, and Executive Order 14389 terminated that tariff on February 20, 2026; they are no longer collected. On semiconductors chips, South Korea pays its MFN base rate plus a Section 232 duty of 25%, while Taiwan pays its MFN base rate plus a Section 232 duty of 25%. That puts the total effective rate at 25% from South Korea and 25% from Taiwan. Section 122 lapsed to 0% on July 24, 2026 and contributes nothing to either figure, and on this product category the two origins land at the same total — so the choice between them turns on freight, lead time and supplier fit rather than on tariffs.

Trade Agreement Status
South Korea has no negotiated bilateral rate charged on its goods — any country-specific reciprocal rate it once carried was terminated on February 20, 2026 — and Section 122 lapsed to 0% on July 24, 2026, but South Korea is on the forced-labor Section 301 covered list at the 12.5% tier, with Section 232 goods carved out and the charge on any given product depending on its MFN rate. Taiwan has no negotiated bilateral rate charged on its goods — any country-specific reciprocal rate it once carried was terminated on February 20, 2026 — and Section 122 lapsed to 0% on July 24, 2026, but Taiwan is on the forced-labor Section 301 covered list at the 10% tier, with Section 232 goods carved out and the charge on any given product depending on its MFN rate. For products under Section 232 national security tariffs, S232 rates govern: a bilateral deal rate does not displace them, and Section 122 never applied to S232-covered goods while it was in force, before it lapsed to zero on July 24, 2026. 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
Source from South Korea when importing semiconductors chips and auto parts components, where its tariff rates are more competitive. Source from Taiwan for consumer electronics and industrial machinery, where it carries the tariff advantage. Beyond tariff rates, factor in lead times, minimum order quantities, quality standards, and freight costs — the total landed cost comparison may shift depending on shipment volume and logistics conditions.

Savings Analysis
On a $10,000 shipment of semiconductors chips, importing from South Korea saves $0 in duties compared to Taiwan — a 0% reduction in total import costs. South Korea incurs $2,650 in duties on the $10,000 shipment, while Taiwan incurs $2,650. This difference compounds across larger order volumes and is a key factor in supplier selection decisions for importers sourcing semiconductors chips.
Frequently Asked Questions
The total effective tariff rate on semiconductors chips is 25% from South Korea and 25% from Taiwan under current 2026 tariff policy. These rates include the MFN base rate, any persisting bilateral deal rate, Section 232 duties for covered products, Section 301 tariffs for Chinese goods, and the forced-labor Section 301 duty that backfills the lapsed Section 122 surcharge for roughly 60 covered economies (Section 122 itself lapsed to 0% on July 24, 2026 and no longer applies).

South Korea does not have a formal trade agreement with the United States. Section 122 lapsed to 0% on July 24, 2026, so imports from South Korea now face either a forced-labor Section 301 duty (if South Korea is on the roughly 60-economy covered list) or the base MFN rate alone with no special-tariff layer.
Taiwan does not have a bilateral trade agreement with the US. Section 122 lapsed to 0% on July 24, 2026, so imports from Taiwan now face either a forced-labor Section 301 duty (if Taiwan is on the roughly 60-economy covered list) or the base MFN rate alone with no special-tariff layer.
Taiwan is cheaper for consumer electronics with a 10% total tariff rate, compared to 12.5% from South Korea. On a $10,000 shipment, this 2.5% rate difference saves $250 in duties when sourcing from Taiwan.
Section 122, enacted in February 2026 for up to 150 days, imposed a global surcharge on most US imports until it lapsed on July 24, 2026. Section 122 no longer applies to South Korea — it lapsed on July 24, 2026 — but South Korea is on the forced-labor Section 301 covered list at the 12.5% tier, which backfilled the lapsed surcharge. Section 122 no longer applies to Taiwan — it lapsed on July 24, 2026 — but Taiwan is on the forced-labor Section 301 covered list at the 10% tier, which backfilled the lapsed surcharge. Since the lapse, a forced-labor Section 301 duty (10%/12.5% on ~60 economies) has backfilled the surcharge for most importers — model the realized post-July-24 structure, forced-labor duty included, when planning shipments.
