HS Code for Hot rolling mill

Hot rolling mills are classified under HS code 8455.21. This classification is part of Chapter 84, which covers nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8455 specifically covers metal-rolling mills and rolls therefor. The subheading 8455.21 is designated for 'Hot or combination hot and cold' rolling mills. The classification is based on the machine's primary function: the reduction of the cross-sectional area of metal by passing it between rotating cylinders (rolls). Because the machinery is designed to handle metal at high temperatures (hot-rolling) or is a versatile unit capable of both hot and cold processes, it is distinguished from purely cold-rolling mills. This classification includes the housing, rolls, and the integrated mechanical components required for the rolling process, following GRI 1 and Note 3 to Section XVI regarding composite machines.

Products Included

• Hot strip mills for steel production
• Blooming and slabbing mills
• Plate rolling mills (hot)
• Combination hot and cold rolling mill stands
• Steckel mills for hot-rolling

Common Misclassification

A common misclassification is 8455.22, which is reserved exclusively for cold-rolling mills. Another frequent error is attempting to classify individual rolls under 8455.21; however, rolls for mills are specifically classified under 8455.30. Furthermore, auxiliary machinery like cooling beds or coilers, if shipped separately, might be classified under 8479 or 8428, though they are often included here if part of a complete mill system.

FAQ

What is the HS code for a hot rolling mill?
