Lumber mill hit by diesel spike

A Kentucky lumber mill that was already getting squeezed by trade costs just got hit from a second direction: diesel. Spectrum News reported on April 10 that the mill’s owner said fuel jumped so fast that trucking and equipment costs started climbing on top of months of tariff pressure. (spectrumnews1.com) That matters because a lumber mill burns diesel in more than one place. Logs arrive by truck, finished boards leave by truck, and loaders, skidders, and other heavy equipment on the yard often run on the same fuel. (spectrumnews1.com) The national fuel backdrop really did move. The United States Energy Information Administration’s April 7 update showed the average U.S. on-highway diesel price at about $4.09 a gallon, up roughly 16 cents from the prior week, while the Midwest average was about $3.97. (eia.gov 1) (eia.gov 2) When diesel jumps like that, a mill cannot just “wait it out” if it has standing deliveries. A load of lumber still has to get from a rural yard to a builder, a hardware store, or a job site, and each extra dime per gallon gets baked into freight bills. (eia.gov) (spectrumnews1.com) The trade side has been a problem for months. The National Association of Home Builders said in 2025 that Canadian lumber was spared some global reciprocal tariffs, but builders should still expect price volatility because companies across the supply chain face different tariff rules and adjustment costs. (nahb.org) Canadian softwood is still carrying heavy duty pressure of its own. The National Association of Home Builders said combined duties on U.S. imports of Canadian softwood lumber were near 45% in late 2025, and the British Columbia Lumber Trade Council said preliminary April 2026 review results pointed to a combined rate near 24.83% for the latest review period. (nahb.org) (bclumbertrade.com) That creates a weird market for buyers. Lumber itself does not have to be scarce for local prices to stay stubbornly high, because the board can be cheaper at the mill and still cost more by the time tariffs, handling, and diesel-powered transport are added. (nahb.org) (eia.gov) Builders are the first to feel it on quotes, but do-it-yourself shoppers feel it too. A small contractor pricing a deck or a homeowner replacing fence boards is buying the same two things at the end of the chain: wood and the cost of moving wood. (nahb.org) (spectrumnews1.com) There is also a reliability problem, not just a price problem. If a local mill trims runs, delays shipments, or turns cautious on inventory because margins are getting crushed, nearby yards and job sites can see slower replenishment even before shelves look empty. (spectrumnews1.com) So even if the tariff fight cools later, diesel can keep the pressure on. The mill’s problem in Kentucky is that the cost of getting lumber from forest to saw to truck to customer has risen at multiple steps at once, and none of those steps disappears overnight.
