MINNEAPOLIS (AP) - Minnesota's U.S. senators are welcoming a ruling from the International Trade Commission that they say will open the door for strong action against the dumping of South Korean steel on the American market.

The ITC found that unfairly priced steel pipes used in oil drilling from South Korea and four other countries are harming U.S. steelmakers.

The decision will allow the Commerce Department to impose tariffs to offset their gains. The decision also applies to steel piping from India, Taiwan, Turkey, Ukraine and Vietnam.

Both Sens. Amy Klobuchar and Al Franken had urged the ITC last month to take action to protect the domestic steel industry.

Klobuchar and Franken issued statements Friday calling the decision a victory for Minnesota's iron mining industry that will protect jobs.
