The tariff on hot-rolled steel products is expected to take effect from March 8 and will be in place for 120 days, according to a trade ministry document dated Feb. 21. A ministry official confirmed the content of the document.
Among companies hit by the 27.83% duties are Baoshan Iron & Steel and Maanshan Iron & Steel. Guangxi Liuzhou Iron and Steel Group will face duties of 19.38%, the document said.
It also said hot-rolled steel products from India would not face anti-dumping tariffs.
Vietnam launched an anti-dumping investigation in July following complaints from Vietnamese producers.
The government had said that in the January-September period last year Vietnam imported nearly 8.8 million tons of hot-rolled steel, 72% of which originated from China.
The total value of steel and iron ore and steel and iron products imported from China last year was nearly $12 billion, Vietnam's customs data shows.
