The announcement stated that the tariff increase was to protect the country's clean technology industry from the impact of cheap foreign supplies. Increased tariffs on polysilicon and wafers would complement near-term investment, encourage diversification away from Chinese sources, and provide China with additional leverage to eliminate the conduct, policies and practices under investigation and reduce the likelihood of being affected by these harmful conduct, policies and practices. While higher tariffs may lead to higher prices initially, they are necessary to allow U.S. domestic producers to compete with China's massive excess capacity, protect near-term investment, and encourage more domestic manufacturing.
