The Trump administration’s decision to impose tariffs on imported steel and aluminum is unpopular with many industries,including the chemical sector. The U.S. industry’s leading trade group, the American Chemistry Council (ACC), is condemning the measure, saying it will hurt industry competitiveness.

The ACC has asked Trump to reconsider the tariffs because they will drive up the cost of building chemical plants in the U.S.

“For a chemical manufacturing industry that has invested $185 billion in new factories, expansions, and restarts of facilities around the country,President Trump’s announcement comes at the worst possible time,” ACC said.”More than half of these investment projects are still in the planning stage, and market shifts caused by tariff increases may convince investors to do business elsewhere.”
