Tariffs bite manufacturers, outlooks mixed
Reports say U.S. tariff changes are imposing steep costs on industrial parts makers, with some executives describing the impact as 'insane'. At the same time, Canada’s Martinrea said it is maintaining its 2026 outlook despite the tariff changes ( ).
U.S. tariff changes are driving up costs for Canadian industrial parts makers, even as auto supplier Martinrea says its 2026 forecast still holds. (martinrea.com) Martinrea said on April 16 that it is maintaining its full-year 2026 outlook after amended Section 232 tariffs on steel, aluminum and copper took effect on April 6. The company said its United States-Mexico-Canada Agreement-compliant auto parts remain exempt under a separate auto-parts arrangement, and any hit on raw-material inputs should be “modest.” (martinrea.com) Other manufacturers are describing a much harsher picture. The Windsor Star reported this week that some Canadian industrial parts executives called the new U.S. tariff costs “insane” and warned that shop closures are possible without federal relief. (windsorstar.com) The split starts with what is being taxed. A U.S. Customs and Border Protection tariff overview says imported autos have faced a 25% tariff since April 3, 2025, and imported auto parts since May 3, 2025, with exemptions for United States-Mexico-Canada Agreement-eligible goods. (cbp.gov) The April 2026 changes hit metal products more broadly. The White House said articles made entirely or almost entirely of steel, aluminum or copper now face a 50% tariff, while derivative articles substantially made from those metals face a 25% tariff; some metal-intensive industrial and grid equipment will pay 15% through 2027. (whitehouse.gov) That matters in places like Windsor-Essex, where tool, mold and industrial parts shops often sell into U.S. auto and factory supply chains but do not always fit neatly inside the auto-parts exemptions. The White House proclamations say the metal tariffs and the auto-parts tariffs run under separate Section 232 actions. (whitehouse.gov; whitehouse.gov) Canadian manufacturers have been warning about this for months. In August 2025, the Canadian Association of Moldmakers said extending U.S. steel and aluminum tariffs to include molds would threaten thousands of jobs and damage a supply chain that depends on cross-border trade. (canadianmetalworking.com) Canada has eased some of its own retaliation, but not in these sectors. Ottawa says it removed many counter-tariffs on U.S. goods on September 1, 2025, while keeping tariffs on steel, aluminum and automobiles in place as negotiations with Washington continue. (canada.ca) For now, the same tariff regime is producing two very different outcomes: Martinrea says exemptions and customer pass-throughs should protect its 2026 results, while smaller industrial suppliers say the new metal duties are landing directly on their invoices. Martinrea said it will give more detail on its first-quarter 2026 results call on April 30. (martinrea.com; windsorstar.com)
