President Donald Trump said on 22 Aug. that the United States has begun a “major tariff investigation” into imported furniture, the latest sector-specific trade action of his administration. The probe is slated to conclude within 50 days, after which furniture arriving from overseas will face a duty at a rate still being set, according to a statement posted on Truth Social. Trump argued the measure would encourage manufacturers to shift production back to states such as North Carolina, South Carolina and Michigan. The move follows earlier levies on cars, steel and aluminum and comes amid continuing efforts to overhaul U.S. trade relationships. Investors quickly marked down companies heavily reliant on foreign supply chains. Wayfair fell roughly 9% in after-hours trading, while RH and Williams-Sonoma each slid about 7%; Arhaus also declined. La-Z-Boy, which manufactures most of its products domestically, edged higher, CNBC reported. The prospective tariff lands as the furniture industry contends with softer demand tied to elevated mortgage rates and stubborn inflation. Trade analysts cautioned that new duties could raise costs for retailers that depend on overseas suppliers and further cloud the outlook for a sector already under pressure.
