BEIJING, Jan 11 (Reuters) - China has increased dumping tariffs on imports of a U.S. animal feed ingredient known as distillers' dried grains (DDGS) from levels first proposed last year, potentially escalating a trade spat between the world's two largest economies.
In its final ruling, the Commerce Ministry said on Wednesday that anti-dumping duties will range from 42.2 percent to 53.7 percent, while anti-subsidy tariffs will be between 11.2 percent and 12 percent.
That's up from anti-dumping duties of 33.8 percent and anti-subsidies of 10 percent to 10.7 percent in its preliminary decision in September.
The rates will take effect from Thursday and be in force for five years.
