The preliminary anti-dumping duties imposed are in addition to duties ranging from 2 to 438% announced by the Commerce Department in November to offset government subsidies given to Chinese wire decking producers.
Last week, the US International Trade Commission approved duties ranging from 10 to 16% on some $2.74 billion worth of Chinese-made oil well tubing and casing in the biggest US trade case against China.
The same day, the United Steelworkers union and four US companies filed a new petition asking for duties of at least 109 to 274% on Chinese-made drill pipe.
Reuters reported Chinese producers and exporters could still escape the duties if the US International Trade Commission determines US producers have not been materially injured, or threatened with material injury, by the imports. That will not be decided until July.
