US lumber futures have fallen from their all-time highs after president Trump’s delay to tariffs on Canada this week halted a surge in prices. Contracts tracking a truckload of lumber hit the highest point in their 30-month history this week. …Trump initially planned to impose 25% tariffs on critical Canadian imports, boosting prices, but Thursday’s pause for a month pushed prices for delivery in May down more than 6% over two days, to $651 per MBF. Even so, prices remain elevated as Trump also ordered a federal investigation into Canadian companies potentially dumping excess supplies into the US market. …Together with potential tariffs, the total duty on Canadian imports could rise from 14.5 per cent to 52 per cent. “This is going to be devastating for Canadian producers,” said Dustin Jalbert, senior economist for wood products at price reporting agency Fastmarkets. “No Canadian producer is making the margin to be able to absorb that.”
