Sourcing from Taiwan in 2026 means paying 10% Section 122 on most product lines — down from 32% in 2025 after SCOTUS struck down the IEEPA reciprocal rate on February 20. Taiwan ships roughly $111 billion of goods to the US per year, two-thirds of which is semiconductors, ICT components, and electronics. The country's the dominant source for advanced-node chips (TSMC owns roughly 92% of global sub-7nm production), printed circuit boards, server-class connectors, and machine-tool subassemblies. Three layers complicate the math: 25% Section 232 on semiconductors imposed October 2025 stacks on top of the 10% Section 122 baseline, the 50% Section 232 still hits Taiwanese steel and aluminum, and Taiwan was named in USTR's March 11 Section 301 investigation covering 16 Asia-Pacific economies. Here's the actual rate stack, the supplier setup workflow, and a $40,000 PCB container worked end-to-end.
Taiwan's Tariff Stack Today (May 2026)
Taiwan pays 10% Section 122 on every entry — that's the post-SCOTUS baseline that took effect February 24, 2026. There's no FTA between the US and Taiwan; the bilateral framework agreement (TIFA) covers trade dialogue but doesn't grant tariff preferences. So MFN base rates apply in full, in parallel with Section 122. Sector exposures: 25% Section 232 on semiconductors (chapters 8541, 8542 specifically, imposed October 2025), 50% Section 232 on steel and aluminum (Proclamation 10896, June 2025), 25% Section 232 on autos, and 50% on copper. Most consumer electronics and machinery sit at 0-3% MFN, so the all-in stack on those is 10-13% — meaningfully cheaper than China's 35-45% effective. See tariffs today for the full current stack across all countries.
What Taiwan Actually Ships to the US
The export profile is concentrated. Semiconductors (chapters 8541, 8542): roughly $52 billion in 2025 — TSMC, UMC, and PSMC integrated circuits dominate, plus packaged finished chips from ASE and SPIL. ICT and computing hardware: $28 billion — server motherboards from Quanta and Wistron, GPU subassemblies from MSI, networking gear from Accton and Wiwynn. Machine tools: $4 billion — Hiwin, Tongtai, and Buffalo Machinery linear actuators and CNC lathes. Bicycles and components: $2.4 billion — Giant, Merida, and SRAM-Taiwan groupsets. Steel pipe and tube: $1.5 billion (now subject to 50% Section 232). Plastics, fasteners, hand tools: $5 billion combined. The semiconductor concentration is what makes Taiwan irreplaceable in the short term, regardless of where Section 301 lands.
Step-by-Step: Setting Up Taiwan Sourcing
Step 1: Identify a vendor. TAITRA runs supplier directories at taiwantrade.com — usable for first-pass lists, though due diligence still falls to you. Step 2: Verify factory ownership. Many Taiwan-listed suppliers are owned by Chinese parents — origin determination follows substantial transformation, not corporate structure, but BIS Entity List exposure can flow through Chinese parents. Step 3: Sign an NDA before sharing technical drawings. Step 4: Get HTS classification right — Taiwanese suppliers regularly misclassify on commercial invoices to lower buyers' duty exposure. Verify against the USITC HTSUS database before goods sail. Step 5: Source freight. FCL from Kaohsiung or Taichung to Long Beach runs $2,200-$3,400 per 40-foot container in May 2026. Step 6: Marine cargo insurance at 0.3-0.5% of CIF. Step 7: At entry, your broker files Form 7501 through ACE; pay duty within 10 working days of release.
Worked Example: $40,000 PCB Container from Kaohsiung
A $40,000 CIF container of multilayer printed circuit boards from a Kaohsiung supplier, classified under HTS 8534.00.00 (printed circuits). MFN: 0% (most chapter 85 PCB lines are MFN-free). Section 122: 10% = $4,000. Section 232: 0% (PCBs aren't classified as semiconductor wafers under the chapter 8541/8542 definition). Section 301: 0% (no Taiwan Section 301 has landed yet). MPF at 0.3464% = $138.56. HMF at 0.125% = $50.00. Total entry cost: $4,188.56. Effective rate: 10.5%. Same container from China: 0% MFN + 10% Section 122 + 25% Section 301 = $14,188.56, effective 35.5%. Taiwan delta vs. China on a single PCB container: $10,000. For a buyer running 50 containers a year — typical for a mid-size EMS — that's $500,000 a year in duty avoidance versus China sourcing.

The Semiconductor Section 232 — 25% That Doesn't Move
Section 232 on semiconductors landed October 2025 under Proclamation 10921 — 25% on all foreign-made chips entered under chapter 8541 (diodes, transistors, photovoltaic cells) and chapter 8542 (integrated circuits). Taiwan-origin chips pay it. So do Korean, Japanese, and Malaysian chips — there's no country-of-origin shopping. The 232 rate stacks on top of Section 122: a $100,000 shipment of TSMC-fabbed integrated circuits pays $25,000 Section 232 + $10,000 Section 122 = $35,000 total (35%). MFN on chapter 8541/8542 is 0%, which is the only relief. There's a narrow exemption for chips packaged at qualifying CHIPS Act fabs (TSMC Arizona, Samsung Texas, Intel Ohio), but most Taiwan-fab chips don't qualify. If your BOM includes Taiwan-fab silicon, model 35% effective duty into Q3 2026 forecasts.
TSMC Arizona, Foxconn, and What Big Buyers Are Doing
TSMC's Arizona Fab 21 began commercial production of 4nm chips in late 2024 and is ramping 3nm and 2nm capacity through 2027 — Apple, AMD, and Nvidia have public commitments to source US-fabbed silicon to skirt the 25% Section 232. Apple's iPhone 17 A19 chip is being dual-sourced from TSMC Arizona and TSMC Taiwan. Foxconn's Wisconsin operation pivoted to data-center server assembly in 2024 — domestic-assembled servers avoid Section 122 on the assembled article, though component-level duty still applies on imported subassemblies. For mid-size buyers, the practical move is checking whether your TSMC-routed orders can shift to TSMC Arizona allocation, even at a 15-20% wafer-cost premium — the 25% duty avoidance often pays for the premium on volume.
Taiwan vs. China vs. Vietnam — Where Taiwan Wins
Taiwan beats China by ~25 points on most consumer electronics — 10% effective versus 35% — which is why mid-tier brand owners (Acer, Asus, MSI, Razer) keep manufacturing in Taiwan rather than moving south. See the China tariff rate breakdown for the 35% effective math on Chinese electronics. Taiwan beats Vietnam on machine tools and precision metal parts because the Taiwanese supplier base has 30+ years of engineering depth — Vietnam doesn't yet. Vietnam beats Taiwan on apparel, footwear, and furniture (Taiwan barely produces any of these). For semiconductors, all foreign sources pay 25% Section 232 — there's no country-of-origin shopping. For steel: Taiwan and EU both pay 50%, Korea uses its bilateral quota. The clean Taiwan-only category is high-precision electronics manufacturing where chip and PCB content dominates.
Action Checklist for Q3 2026 Taiwan Programs
Step 1: For active 2025 entries between April 5 and February 24, file IEEPA refund claims through the CAPE portal — Taiwan paid 32% IEEPA during that window, refundable back to the 10% baseline. The refundable difference is roughly $22 per $100 of CIF value. Step 2: For Q3 2026 contracts, write duty escalation clauses tied to Section 301 announcements. Step 3: Verify HTS classification for any chapter 85 lines — the line between PCB (0% MFN, no Section 232) and integrated circuit (25% Section 232) is sharper than suppliers admit. Step 4: For semiconductor-heavy BOMs, get TSMC Arizona allocation quotes from major customers' fab schedulers. Step 5: Subscribe to USTR Section 301 docket on Taiwan — determination expected by mid-July. Step 6: For steel/aluminum content, run shadow USMCA quotes from Mexican or Canadian suppliers to drop the 50% Section 232 layer entirely.
Key Takeaway
Taiwan at 10% Section 122 is the cheapest non-USMCA, non-Korea source for high-precision electronics and machinery in May 2026. A $40,000 PCB container costs $4,189 in duty versus $14,189 from China — a 70% saving that explains why Acer, Asus, and the Tier-1 EMS providers haven't moved out. The semiconductor 25% Section 232 is unavoidable for chip-heavy BOMs unless you can land TSMC Arizona allocation. The July 24 Section 122 sunset and the parallel USTR Section 301 investigation create real Q3 risk: Taiwanese duty could jump 15-25 points by late summer. Run the landed cost calculator with current freight, file any 2025 IEEPA refunds through CAPE, and write escalation clauses into Q3 contracts.
