JA Solar Holdings Co., Ltd.(Nasdaq:JASO) ("JA Solar" or the "Company"), one of the world's largest manufacturers of high-performance solar power products, has responded to the final determination by the U.S. Department of Commerce ("DOC") on imposing anti-dumping duties on China-produced solar products.

In its final decision, the DOC determined that crystalline silicon photovoltaic ("PV") cells produced in China, whether or not assembled into modules, would be subject to antidumping and countervailing duties. Under the ruling, solar modules assembled in China from cells produced in third countries do not fall within the scope of the duties. The U.S. International Trade Commission ("ITC") will make its final determination on or before November 23, 2012.

Pursuant to the DOC's determination, PV cells produced in China by JA Solar will be subject to an antidumping duty of 25.96% and a countervailing duty of 15.24%.

Jonathan Pickering, president of JA Solar USA, commented, "We are pleased that the dispute is coming to a close and that the scope of the investigation was not expanded. JA Solar cooperated fully with the DOC during its investigation, and we continue to state our case to the ITC."

Mr. Pickering continued, "We remain focused on addressing our customers' need for high-quality, high-performance products, and we're determined to play an active role in the rapid growth of the U.S. market."
