Tariff Armageddon and the GPU Loopholes

SemiAnalysis, April 10, 2025. By Dylan Patel, Jeremie Eliahou Ontiveros, Patrick Zhou and colleagues.

Key Takeaways

• The regime: a 10% baseline tariff on all imports plus country-specific reciprocal rates of 11–50%; China at 145% total, Taiwan at 32%.
• The loophole is a classification question. Under USMCA’s Most-Favored-Nation provision, goods classed as “digital processing units” or “automatic data processing machines” enter duty-free from Mexico or Canada regardless of where they were manufactured — so GPUs routed through Mexico avoid the tariff entirely.
• The cost impact is smaller than the headlines: datacenter construction up mid-to-high single digits, but under 2% of total cost of ownership. Wafer fab equipment ~15% more expensive for US manufacturers; optical modules up 25–40%.
• Mexico becomes the assembly hub — Foxconn is already building GB200 server capacity there.

Connections

• Ingested for Chips For America - Research, and it is the piece that most complicates that draft’s thesis: the policy’s effect ran through customs classification rather than through industrial capacity. A tariff regime that reroutes assembly to Mexico has not reshored anything.
• The under-2%-of-TCO finding is a useful corrective to bubble-adjacent claims in Bubble Architecture — tariffs are not what makes AI infrastructure expensive.
