Context on logistics:
- COMEX delivery has historically centered on 100 oz bars (with other deliverables allowed in recent years). A tariff on Swiss-origin 1kg/100oz bars could tighten U.S. supply in the near term, but alternative sources and forms (e.g., London bars, non‑Swiss refineries) can partly offset over time—just at higher friction/cost.
