CHINA will levy anti-dumping duties of between 50.3-105.4 percent on imports of United States chicken products from today, the Ministry of Commerce said yesterday.

The US chicken industry has dumped broiler products into the Chinese market and caused substantial damage to the domestic industry, the ministry said in an online statement, citing the results of an investigation initiated a year ago.

"The ruling is that there is a causal relationship between the US dumping of broiler products and the losses suffered by domestic businesses," the statement said.

The tariff rate for products China imports from Tyson Foods Inc and Keystone Foods LLC is 50.3 percent and that for Pilgrim's Pride Corporation is 53.4 percent, according to the statement.

Sanderson Farms Inc and 31 other firms face 51.8 percent duty. Other US producers face a 105.4-percent duty.

The anti-dumping measures will be applied to the products for five years, the statement said.

In late August China imposed anti-subsidy duties from 4-30.3 percent on US chicken products for five years.
