The US Commerce Department ruled that Chinese TV makers were dumping on the US market, a decision that could result in import duties of between 28 and 46 percent being slapped on TV sets made in China.
Importers from China will have to post cash deposits or bonds pending announcement of final anti-dumping duties in April.
The US finding stated that Chinese TV makers TCL, Sichuan Changhong Electronic, Shenzhen Konka Group and Xiamen Overseas Chinese Electronic were all selling TVs at unfairly low prices.
In the same ruling the department dismissed a dumping complaint against a Malaysian TV exporter.
The ruling follows a decision by the US to set new quotas on Chinese textiles in 2004 and impose duties of 11 percent on pipe fittings from China.
Chinese soybean, cotton and wheat-buying teams postponed visits to the US after the decision on textiles and Beijing said it would retaliate against some imports from the US, but gave no details.
