What are the three likely scenarios for Trump's copper tariff decision, and what are their key implications according to the article?

The article outlines three likely scenarios: (1) 'Push Ahead' — imposing a 15% tariff on refined copper imports starting in January 2027 (with potential escalation to 30% in 2028), which would likely trigger increased metal shipments into Comex warehouses and push prices higher, benefiting US-based producers like Freeport-McMoRan and Rio Tinto; (2) 'Stand Down' — ruling out tariffs entirely, which would eliminate incentives to ship copper into the US, potentially reversing flows from Comex to LME warehouses and easing global supply pressures, while critics warn it would raise costs for US manufacturers already facing 50% tariffs on semi-finished copper products; (3) 'Delay Decision' — postponing the announcement beyond the Commerce Secretary’s end-of-June review, though the article cuts off before elaborating on this option’s implications.

Why might copper tariffs be considered more legally durable than Trump’s other trade measures, according to the article?

According to the article, copper tariffs may be seen as a more durable measure because they would stem from a separate national security review process, unlike Trump’s sweeping tariffs that are currently facing legal challenges.
