The European Union's Carbon Border Adjustment Mechanism (CBAM) mirrors the United States' Section 232 tariffs in both intent and effect, despite differing justifications. While the US imposes tariffs on steel and aluminium under national security provisions, the EU frames CBAM as a climate measure targeting carbon-intensive imports.

Both policies shield domestic industries from foreign competition. US tariffs reach 25% on primary steel and comparable duties on aluminium, extending to derivative products. CBAM requires importers to report embedded emissions and surrender certificates priced at roughly €80 per tonne of CO₂, effectively raising import costs.

The EU criticizes US protectionism while expanding CBAM's scope, contradicting its Framework Agreement commitments. US Ambassador to the EU Andrew Puzder argues this double standard undermines European credibility on rules-based trade. Both measures increase relative prices of targeted imports versus domestic alternatives.

A shipment of steel-containing machinery faces US duties based on metal content, while the same goods encounter EU fees based on production emissions. Neither approach aligns with genuine free trade principles when protectionism wears different labels.
