A safeguard investigation seeks to determine whether increased imports of a product are causing, or is threatening to cause, serious injury to a domestic industry.
The Indonesian Safeguards Committee concluded that there was sufficient evidence to justify the initiation of such an investigation after examining the documented application filed by PT Ispat Indo and PT Krakatau Steel, according to the statement.
The two companies had applied for safeguard measures against the importation of hot rolled bar and rod in irregularly wound coils of iron or non-alloy steel or of other alloy steel, which fall under HS Codes 7213.91.10.00, 7213.91.20.00, 7213.91.90.00, 7213.99.10.00, 7213.99.20.00, 7213.99.90.00, and 7227.90.00.00.
The investigation started on January 17.
