Aluminum Weldment Housing for Cold Rolling Mill
> This is a fabricated aluminum weldment serving as the housing for bearings and rollers in a cold rolling mill, weighing 32 tons. It is a structural component of the mill, not a roll itself, and is presented as a part of a metal-rolling mill. Because it is a weldment weighing less than 90 tonnes, it falls under tariff item 8455.90.10.
8455.90.10Cast Iron Base Casting for Tandem Rolling Mill Stand
> This is a heavy cast iron base casting designed to support tandem rolling mill stands in steel production, weighing 28 tons. It is a structural foundation component of the rolling mill, not a roll, and is presented as a part. Since it is a casting weighing less than 90 tonnes, it is classified under tariff item 8455.90.10.
8455.90.10Ductile Iron Roll Stand Casting for Section Mill
> This is a precision ductile iron casting for the roll stand housing in section steel rolling mills, weighing 41 tons. It is a structural part of the mill stand, not a roll, and is presented as a part of a metal-rolling mill. As a casting under 90 tonnes, it falls under tariff item 8455.90.10.
8455.90.10Heavy Steel Weldment for Rolling Mill Catenary
> This is a welded steel structure for the catenary (loop) section in continuous rolling mills, weighing 67 tons. It supports strip tension control and is a structural part of the rolling mill, not a roll. As a weldment under 90 tonnes, it is classified under tariff item 8455.90.10.
8455.90.10Steel Frame Casting for Hot Rolling Mill
> This is a large steel casting forming the main frame of a hot rolling mill stand, weighing 45 tons. It is designed to withstand extreme pressures during metal deformation and is a structural part of the mill. As a casting under 90 tonnes, it falls under tariff item 8455.90.10.
8455.90.10Steel Welded Side Frame for Plate Rolling Mill
