(CNN) President Donald Trump said Tuesday that his promised tariffs on steel and aluminum imports -- 25% on steel, 10% on aluminum -- would be applied in a "very loving way."

But at least a few states might not be feeling it.

Despite Trump's adverting the tariffs as a worker protection , many businesses in states that carried him in the election, including manufacturers in the Rust Belt region, rely heavily on steel and aluminum imports, according to a new report from the Brookings Institution . Brookings analyzed how reliant states are on aluminum and steel imports as a share of total state imports.

Louisiana, one of the largest importers, relies on steel and aluminum imports to support its oil and gas industries. Already, Royal Dutch Shell has said a tariff could affect its decision to develop a planned Gulf of Mexico project

Wisconsin Republican Gov. Scott Walker warned the tariffs could hurt the state's canning and beer industries.
