The US Department of Commerce (DOC) yesterday made a preliminary determination to impose anti-dumping tariffs of just over 31% on crystalline silicon PV cells from major Chinese producers, after ruling that exporters sold product in the US at "less than fair value".

SolarWorld, the Germany-based producer whose US arm led the complaint that produced the decision, will now proceed with plans to file a similar grievance in Europe later this year, according to reports.
