U.S. solar challenging tariff ruling

U.S. solar panel tariffs spark a Customs and Border Protection dispute over bypass diodes, trade policy, and Chinese subsidies, impacting clean energy imports, manufacturers like Trina Solar, and cases at the Court of International Trade.

The U.S. solar energy industry hopes to persuade Customs officials to reverse a decision to impose a 2.5 percent tariff on solar panel imports after more than two decades of duty-free trade in the product, an industry official said.

"We're taking it very seriously and we will be responding.... The industry is in the process of preparing a challenge," said Rhone Resch, president of the Solar Energy Industries Association, whose members include both U.S. and foreign solar energy companies.

In the worst-case scenario, U.S. importers of solar panels could face some $70 million in solar tariffs and penalties for product already imported this year.

The tariff comes at a time when concern about global climate change has prompted the United States and the European Union to push for deal with other leading developed countries and China to eliminate duties on environmental goods, consistent with ongoing U.S. clean energy outreach to China efforts worldwide.

As the New York Times reported earlier, the U.S. Custom service ruled in January a panel made by Trina Solar of China was a generator because it contains a diode that allows electric current to pass around shaded areas of the panel.

That ruling was a surprise because "all solar panels contain bypass diodes and have forever. It's a safety issue not to have them," one industry official said.

Although the ruling only applies to the Trina panel, it has implications for other manufacturers, he said.

The industry hopes it can persuade officials at U.S. Customs and Border Protection headquarters in Washington to overturn the ruling made by the New York office.

If that fails, the case could go to the U.S. Court of International Trade in New York.

Mike Wessel, a commissioner on the U.S.-China Economic and Security Review Commission, a congressionally appointed watchdog group, said the duty should stay in place to offset Chinese clean energy subsidies to its domestic producers.

"Customs' decision is the right approach to ensure that the domestic industry we have does not get run further into the ground by China's efforts to dominate this industry even as it has defended its wind power policies internationally," he said.

The solar power sector is increasingly a global industry, with most panels today being sold into the European market and China, with a booming clean energy sector, expected to grow as a customer for clean energy.

While U.S.-based SunPower Corp assembles panels at factories in China, the Philippines and Mexico, China's Suntech Power Holdings Co Ltd is planning to lease or buy a facility to produce its solar panels in the United States amid a Buy American push by federal agencies, and companies like Yingli Green Energy Holding Co Ltd are setting up distribution lines in the United States.

The tariff could prompt more Chinese companies to set up some sort of U.S. operations. But it also could backfire on the United State if it encourages other countries to impose higher tariffs on climate-friendly goods.

"It's unclear that the U.S. would want to enforce this policy long term... If you move toward a protectionist stance, you also limit what your domestic companies can do abroad," said Christine Hersey, analyst at Wedbush Morgan.

J.P. Morgan analyst Christopher Blansett said the tariffs could be good for First Solar Inc, Energy Conversion Devices Inc and Evergreen Solar Inc, since the companies produce some products in the United States.

But the tariffs should not have a large impact, since the benefits that foreign governments give to companies to set up manufacturing in their country — such as lower corporate tax rates and low-cost financing — "far outweigh the penalty of a 2.5 percent tariff," Blansett said.
