(Bloomberg) -- One of the largest makers of copper wire and cable in the US is applauding the Trump administration for adding import tariffs on aluminum and copper derivative products, saying the move will help American manufacturers.

Without the duties, domestic manufacturers would be “significantly disadvantaged” to foreign suppliers, Southwire Co. Chief Executive Officer Rich Stinson said on the company’s website.

“It is important to us that any tariffs provide a level playing field in the marketplace and minimize any possible negative impact to our business,” Stinson said.

The rare public comment from the closely held company, based in Georgia, comes after US President Donald Trump last month imposed a 50% duty on semi-finished copper imports valued at more than $15 billion. Trump also ordered officials to come up with a plan to impose tariffs on an array of other copper-intensive goods.
