United States applied a anti-dumping tariff on imports of copper tubes from China and Mexico.
Quote from www.chinamining.org:
"The tariffs will average 34.48 percent on U.S. imports from China, which were $233 million in 2009, the Commerce Department said in a statement today. The duties will average 30.9 percent on the $130 million in imports from Mexico. "
Even though LRC does not use chinese copper, this will affect pricing of all copper tubing products in the United States.
