Trade Agreement Status
South Korea has a bilateral deal with the US at 15% (replaces the standard Section 122 rate). Taiwan 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
South Korea 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 Taiwan 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.

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 $2,638 in duties on the $10,000 shipment, while Taiwan incurs $2,638. 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, applicable Section 122 surcharge or bilateral deal rate, Section 232 duties for covered products, and Section 301 tariffs for Chinese goods.

South Korea has a bilateral trade agreement with the US under which a negotiated rate of 15% applies to imports, replacing the standard Section 122 rate. This deal provides more predictable tariff treatment than countries without formal agreements, though its legal durability following the IEEPA ruling remains subject to ongoing policy developments.
Taiwan has a bilateral trade deal with the US at a negotiated rate of 15%, which replaces the Section 122 rate for imports from Taiwan. This creates a differentiated tariff structure compared to non-deal countries.
South Korea is cheaper for consumer electronics with a 16.5% total tariff rate, compared to 16.5% from Taiwan. On a $10,000 shipment, this 0% rate difference saves $0 in duties when sourcing from South Korea.
Section 122, enacted in February 2026 for up to 150 days, imposes a global surcharge on most US imports. South Korea's bilateral deal rate of 15% replaces the standard Section 122 rate. Taiwan's bilateral deal rate of 15% replaces Section 122.
