Solar Startup Asks for Tariff Exemption, Draws Trump Rebuke

A U.S. solar startup has picked its own trade fight with President Donald Trump.

1366 Technologies Inc., which spun out of the Massachusetts Institute of Technology, has drawn a rebuke from the U.S. Energy Department for asking that its silicon wafer factory under construction in Asia be exempt from American tariffs. The Energy Department says the overseas facility may violate an agreement to manufacture in the U.S. as part of a $150-million federal loan guarantee for a factory the startup was planning in Upstate New York.
