US tariffs on wood, machinery, and corn ethanol set to reshape trade landscape this month

New and adjusted duties on wood products, machinery, and corn ethanol are all set to take effect or shift this month, creating a complex web of trade policy changes that touches everything from homebuilding costs to the price of fuel at the pump.

What’s actually changing

Section 232 tariffs on wood began back on October 14, 2025, slapping a 10% tariff on softwood lumber and 25% on certain upholstered wooden products. Some of those rates were deferred into 2026 and 2027, meaning additional duties are now kicking in.

Tariffs on imported farm and construction machinery are dropping from 25% to 15%, a reduction that took effect on June 8, 2026, and will remain in place through the end of 2027.

On June 1, 2026, the US Trade Representative proposed 25% tariffs on most Brazilian goods as part of a Section 301 investigation into Brazil’s trade practices. The ethanol sector sits squarely in the crosshairs, with public hearings scheduled for July 6-7, 2026.

Brazil currently imposes an 18% duty on US ethanol imports. The National Corn Growers Association is actively advocating for retaliatory tariffs during the July hearings.

The Section 122 wildcard

Section 122 tariffs covering a broad range of imports, including machinery, are set to expire around July 24, 2026.

Why crypto and macro investors should care

The machinery tariff reduction from 25% to 15% is broadly positive for the US agricultural and construction sectors. The wood tariff story cuts the other way: the 10% tariff on softwood lumber alone has already been felt in construction budgets, and additional deferred rates taking effect will only compound the pressure.

A 25% tariff on most Brazilian goods would represent a significant escalation in trade tensions with Latin America’s largest economy. For ethanol specifically, higher tariffs on Brazilian imports would likely boost domestic corn ethanol prices, benefiting US producers but raising fuel costs for consumers.

Companies operating in lumber, agriculture, and manufacturing should be stress-testing their supply chains now. For investors across all asset classes, the convergence of three separate tariff actions, the July 6-7 hearings, and the July 24 Section 122 expiration creates concentrated policy risk in a single month.
