The U.S. Commerce Department has set an anti-dumping duty of 111.73 percent on magnesium from Chinese exporter Tianjin Magnesium International Co. Ltd. (TMI).

TMI's suppliers not only failed to adequately cooperate with governmental verification efforts but even took steps to purposely mislead investigators, according to the ruling.

The Commerce report said that TMI's suppliers lacked documentation of payment, had discrepancies in record keeping and altered requested documents. In one instance, Commerce said, a TMI supplier threw accounting records out of an office window while an inspector was locked outside the office. The name of the TMI supplier was redacted from the final report.
