Voestalpine noted it had invested $1.4 billion (€1.1 billion) in the US in recent years, creating 3,000 jobs.
Its 49 sites in the country generated €1.2 billion in revenue last year, and the company said that most of its sales in the United States would not be impacted by the tariffs.
The company which recorded €11.3 billion in sales in its 2016-2017 financial year estimated that only three percent of its overall revenue will be impacted by the tariffs.
The products to be most affected by the tariffs are high-tech steel products which Voestalpine said are largely or completely unavailable in the United States from other suppliers.
It pointed to steel strip used by automobile manufacturers and seamless tubes that are processed in the United States for use in oil and gas exploration.
