China raised the minimum chicken duty to 50.3% from 43.1% on U.S. chicken products, MarketWatch reported. The maximum antidumping tariff remains 105.4%.
"Dumping duties exist in the imported chicken products from the U.S. and has caused substantial harm to China's domestic industry," China's Commerce Ministry said.
Importers that responded to the ministry's investigation must pay the new duty of 50.3% to 50.4% on U.S broiler or chicken products. Companies that didn't respond are subject to the maximum duty of 105.4%.
China, the world's second-largest economy, originally imposed the duty in February.
The decision to raise the duties came a few days after the U.S. announced a decision to impose antidumping and countervailing duties on coated paper from China.
