Tennessee Semiconductor Supply Chain Risk & Policy Shield Simulator

Policy Shield Levers

Chemical Precursor Tariffs 25%

Affects hyper-pure ultra-grade acids & Kingsport solvent feedstock

Silicon Substrate Tariffs 35%

Raw ingots & 300mm foreign wafer slicing surcharges

Lithography & Eq. Duties 20%

Foreign stepper precision components & lens maintenance

Mandated Domestic Content 75%

Required onshore content for auto-electronics procurement

Allied Retaliation Index 40%

Reciprocal export license delays & packaging bottlenecks

Mechanism Note: Shielding policies intent to protect national fabs immediately compress upstream raw input supplies, accelerating lead-time backlogs at Tennessee packaging and assembly plants before domestic refining expands.
