Over 60 firms from China will face a 31 percent import duty for products entering the U.S., a retroactive tariff that will cover shipments made as far back as February 2012. Other Chinese exporters will face a tariff of 250 percent. The tariffs apply specifically to Chinese solar cells — regardless of where the panel is assembled.

In March, Commerce suggested duties of 2.9 to 4.7 percent for Chinese PV imports as a result of a ruling on claims of illegal subsidies to Chinese firms.

"Between now and a final decision before the end of the year, there are many issues that will be addressed and whose resolution would lead to a significantly lower tariff"
