The Ministry of Industry and Trade stated Wednesday the duties, ranging from 4.43 percent to 25.22 percent, became effective Monday after it concluded an anti-dumping investigation commenced in September last year following requests by Vietnamese producers.

The ministry had found evidence Chinese steel producers dumped their products on Vietnam, causing a negative impact on domestic manufacturers.

It said during the investigation period China’s cold-rolled steel accounted for 65.5 percent of Vietnam’s imports while there has been an increase in the amount, although it did not specify by how much.

Vietnam imported $4 billion worth of steel products in the first 11 months this year, up nearly 9 percent year-on-year, with 54 percent of it from China, according to Vietnam Customs.
