The U.S. Department of Commerce has determined that ending the countervailing duty order on circular welded austenitic stainless pressure pipe from China would likely lead to the continuation of unfair government subsidies. In their review, the Department did not receive a sufficient response from the Chinese government but received input from U.S. producers such as Bristol Metals, Felker Brothers, and Primus Pipe and Tube. Because of this lack of response from China, the Department conducted an expedited review. The decision and more detailed information are available in the Issues and Decision Memorandum, which is accessible online.
Simple Explanation
The U.S. Department of Commerce thinks that if the rules about stopping special money support for Chinese pipes are removed, China might keep giving unfair help to their pipe makers. Because China didn't say much about this, the U.S. did a quick check with help from some American pipe makers.
