The Trump administration plans to impose a roughly 15% tariff on imported finished furniture, White House officials told CNBC. The duty is the first concrete action to emerge from a Section 232 national-security investigation that examined whether reliance on foreign lumber and downstream products weakens the U.S. industrial base. Officials said the measure aims to strengthen domestic logging and milling by encouraging furniture makers to source more American wood. The decision broadens the administration’s use of Section 232, which it has previously applied to steel, aluminum, copper and other wood products. Market reaction was swift: lumber futures advanced, while shares of import-heavy furniture retailers including Wayfair slipped in early trading. Industry groups cautioned that the levy could lift consumer prices and add to supply-chain pressures already heightened by a 35% duty on Canadian softwood lumber that took effect earlier this year. Implementation details, including the start date for collecting the new tariff, have yet to be announced.
