The article deals with the impact of tariffs imposed by the U.S. Commerce Department on Chinese solar panel makers under the administration of former President Barack Obama on polysilicn maker Hemlock Semiconductor. China was accused by several U.S. solar panel makers of dumping its panels in the U.S. at below-cost to unfairly grab market share. In response, China announced a tariff of 50 percent on U.S. polysilicon imports in 2014, which resulted in the halting of Hemlock exports there.
