On February 1, 2025, President Trump announced that tariffs of 25% will be imposed on goods imported from Mexico and Canada (with the exception of Canadian energy resources which will be subject to a 10% tariff). In addition, a 10% tariff will also be imposed on certain goods imported from China. The administration’s stated justification for this emergency action is to address the threat posed by illegal aliens and drugs, including fentanyl, that are flowing into the United States. While the details of the tariffs remain unclear, these tariffs will undoubtedly impact both the cost and availability of critical materials required for construction projects across the United States. Accordingly, all contractors would be wise to immediately evaluate applicable clauses in existing contracts that may offer some relief from the time and cost impact resulting from tariffs. Construction attorneys Tyler Lloyd and Steven Henderson take a look at what this will mean to the construction industry in this Stites & Harbison Client Alert.
