The US Commerce Department determined that Chinese solar-product imports should be subject to additional tariffs to offset government subsidies, Blooomberg reported Wednesday,citing an agency document.

The department, which on May 17 announced anti-dumping duties as high as 250 percent on imports from China, found additional state subsidies benefiting the nation’s producers, Bloomberg reported, citing Tim Truman, a department spokesman.

The agency’s tariff determinations are preliminary, and no additional duties will be collected at the US border as a result of the new analysis, Truman said. A final decision is scheduled for Oct 10, he said.
