The latest escalation in U.S.-Canada trade tensions is putting another layer of uncertainty on an office furniture industry that has spent the past 18 months learning to live with tariffs, shifting sourcing strategies and constantly changing landed costs.

For office furniture dealers likely to see costs rise regardless of which direction the furniture is headed, the immediate concern is how quickly those costs move through a project, who absorbs them and how dealers protect margins when a quote made today may carry a very different cost by the time the product ships.

The latest round of U.S. tariffs took effect Aug. 22 after trade negotiations between Washington and Ottawa ended without an agreement. The Trump administration imposed 50% tariffs on roughly US$20 billion of Canadian imports under Section 338 of the Tariff Act of 1930. The measure reaches a broad range of products, including certain furniture categories and furniture-related goods, and unlike many earlier tariff measures, it overrides USMCA preferential treatment for covered goods.

That distinction is significant for the office furniture industry. And all of this is a moving target, so bear with me. For decades, the U.S. and Canadian furniture markets have operated as a highly integrated North American supply chain. Many Canadian furniture products have historically entered the U.S. duty-free when they qualified under the trade agreement. Under the new Section 338 duties, however, products included on the covered tariff list can face an additional 50% duty even when they otherwise qualify under USMCA.

The impact will vary considerably by product. Some Canadian-made furniture products will fall under the new 50% tariffs, while others remain subject to existing tariff regimes or exemptions, including certain products already covered by Section 232 duties. Separately, the U.S. already applies a 25% tariff to certain upholstered wooden furniture under Section 232, with that rate scheduled to rise to 30% in January 2027.

For dealers, that complexity may be almost as problematic as the tariffs themselves.

A dealer specifying a Canadian product now has to determine not only where the product was manufactured, but also its precise tariff classification, the origin of its components and which tariff programs apply. A single manufacturer’s product line could contain items facing very different duty treatment. That makes it critically important for dealers to connect with their Canadian manufacturers and suppliers, who can help them navigate this increasingly complex tariff environment.

All of this creates a difficult pricing environment. Dealers typically sell projects months before installation, while manufacturers may not know their final tariff exposure until an order is entered or shipped. A 50% increase in the import cost of a product cannot always be passed directly to a customer without reopening a specification, changing the product or absorbing some of the increase. It also puts pressure on working capital. Dealers may be required to pay higher costs well before they receive final payment from a customer. On large workplace projects, even a modest change in product costs can represent tens or hundreds of thousands of dollars.

The problem extends beyond products crossing the border. Tariffs on Canadian steel, aluminum and wood products can affect the cost structure of manufacturers operating on both sides of the border. The U.S. and Canada have developed supply chains in which materials and components cross the border multiple times before a finished product reaches a customer. Tariff costs can therefore accumulate at different stages of production.

Canada’s response could create another challenge for U.S. dealers. Prime Minister Mark Carney has announced that Canada will impose dollar-for-dollar retaliatory tariffs beginning Sept. 8. The measures are expected to target U.S. goods in sectors including steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics. The broader uncertainty surrounding those measures could affect American manufacturers and dealers selling into Canada.

The dealer’s role becomes less about simply finding the right product and more about managing risk. Dealers will need tighter communication with manufacturers about tariff exposure, more careful language in quotations and contracts, and potentially shorter quote-validity periods. They may also have to present customers with domestic or alternative-source products when a Canadian specification becomes economically impractical.

There is an opportunity in that disruption. Dealers with strong manufacturer relationships, sophisticated project-management systems and a broad product portfolio can help clients navigate the volatility rather than simply pass along price increases. They can identify equivalent products, evaluate substitutions and understand which specifications are most exposed to tariff changes. That collaboration can work in both directions.

But there is little indication that the current situation will stabilize soon. The latest developments have created renewed uncertainty around the North American trade relationship and raised questions about the longer-term future of USMCA.

For office furniture dealers, that means tariffs are no longer an occasional cost to be handled by manufacturers. They are becoming part of everyday project management.
