The DOC imposed anti-dumping duty rates of 52.13% and anti-subsidy rates of 38.72% on the Chinese solar PV panel imports.
Meanwhile, the anti-dumping rates imposed on Taiwan are lesser when compared to China with 19.50%.
The ruling needs to be confirmed by the US International Trade Commission (ITC), which is anticipated to take a decision at the end of January 2015.
The duties will go into effect around 1 February 2015 if the ITC confirms that the Chinese and Taiwanese trade practices injured domestic manufacturers.
SolarWorld US president Mukesh Dulani said: "These remedies come just in time to enable the domestic industry to return to conditions of fair trade.
"The tariffs and scope set the stage for companies to create new jobs and build or expand factories on U.S. soil."
Yingli Green Energy Americas managing director Robert Petrina said: "We are deeply disappointed in the U.S. Department of Commerce’s decision to accept such a broadly defined scope for this ruling, and to levy harsh, protectionist tariffs.
"It’s well known that our customers, partners, and other stakeholders represent the majority of the solar industry and U.S. jobs. We will continue our vigorous defense on their behalf with the hope that national efforts to increase solar power’s cost-competiveness are not derailed further."
