Trump reshapes steel, aluminum and copper tariffs with US-content carve-outs
A 1 June proclamation cuts farm-equipment duties and rewards high US material content, building a new tariff wall
Summary
On 1 June 2026 Donald Trump signed a proclamation adjusting Section 232 metals tariffs: agricultural equipment (combines, harvesters) cut from 25% to 15%; mobile industrial equipment (bulldozers, forklifts) added to the 15% band when sourced from trade-deal countries; and a new 10% rate for capital equipment containing at least 85% US steel or aluminum. The changes are temporary through 31 December 2027. Bloomberg framed the move as part of a wider June tariff build-out reshaping global winners and losers. It runs in parallel with the USTR proposes forced-labor tariffs on 60 economies — Trump's post-IEEPA tariff vehicle and the Trump declines to renew USMCA, triggering a decade of annual reviews dispute as the United States reconstructs its tariff regime after the Supreme Court voided the IEEPA route.
By the numbers
- 25% → 15% — agricultural-equipment tariff cut.
- 10% — new rate for ≥85% US-content capital equipment.
- 31 December 2027 — sunset of the temporary changes.
- 5 — consecutive months of US manufacturing expansion cited through May 2026.
Why it matters
The US-content carve-out converts tariffs into an industrial-policy lever: rewarding domestic sourcing while easing input costs for farmers and builders. Layered onto the 301 and USMCA fronts, it shows the administration tuning duties as a permanent structural tool, not a one-off shock.
What to watch
- Whether downstream manufacturers actually shift to the ≥85% US-content threshold.
- Allied complaints over the trade-deal-country eligibility test.
- Extensions or expansions before the December 2027 sunset.
