The DGAD, under the commerce ministry, said it has prima facie found "sufficient evidence" of dumping of these products from China.
"The authority hereby initiates an investigation into the alleged dumping, and consequent injury to the domestic industry," the DGAD has said in a notification. In its probe, the directorate will determine existence, degree and effect of alleged dumping and recommend the amount of anti-dumping duty, which if levied would be adequate to remove the injury to the domestic industry.
These steel products are used in several sectors, including automobiles, cement, power plants, turbines, ship-building, railways, capital goods, and construction machinery.
The period of investigation for the present investigation is 2016-17. However, for the purpose of injury investigation, the period will also cover data of 2013-16, it added.
While the DGAD recommends the duty, the finance ministry imposes the same.
Increasing imports and dumping of goods from China have always been an area of concern for Indian companies.
India's exports to China were only $10.17 billion in 2016-17, but imports aggregated $61.28 billion during that fiscal.
The DGAD is also probing dumping of several other products such as certain chemicals from the neighbouring country.
India is one of the most attractive markets for global producers due to its large middle class population.
