China on Monday said it would levy 80.5 percent in punitive tariffs on Australian barley following a government investigation into Australian grain exports. China had found Australian subsidies and dumping had "substantially damaged domestic industry," the commerce ministry said in a statement. A 73.6 percent anti-dumping tariff and 6.9 percent anti-subsidy tariff on imports of Australian barley will take effect Tuesday, the ministry said. tjx/lth/rma
