NEW YORK — Cabinet dealers, interior designers and remodeling contractors in the U.S. hope new tariffs on imported kitchen cabinets, bathroom vanities and upholstered wooden furniture will boost domestic production of those products. But several small business owners in the home improvement industry say they expect some short-term pains from the import taxes. Potential customers may postpone kitchen and bathroom renovations until costs — and the economy — seem more stable. …The American Kitchen Cabinet Alliance lobbied for tariffs to help offset what they described as a flood of cheap cabinets from countries such as Vietnam, Malaysia, China and elsewhere in the decades since manufacturing moved offshore. …Although the White House said the tariffs were intended to boost domestic production and protect U.S. businesses from predatory trade practices, some cabinet makers say that will be difficult because their supply chains are multinational.
