8455.30.00.45 - Exceeding 2,268 kg but not exceeding 6,803.9 kg

This HTS classification covers rolls specifically designed for use in metal rolling mills, where these rolls are manufactured from cast steel and have a weight exceeding 2,268 kg but not exceeding 6,803.9 kg. These components are critical to the metal shaping process, applying pressure to reduce the thickness and/or shape metal through successive passes between the rolls. The material specification of cast steel is a key determinant for inclusion within this subcategory.

This category is distinguished from its siblings primarily by its defined weight range. Rolls weighing 2,268 kg or less fall under HTS code 8455.30.00.35, while those exceeding 6,803.9 kg are classified under 8455.30.00.55. Therefore, the precise weighing of the cast steel roll is the primary differentiating factor at this level of detail.

As a leaf node, this classification does not have further subdivisions. The classification is complete once the article is identified as a roll for a rolling mill, made of cast steel, and its weight falls within the specified range of 2,268 kg to 6,803.9 kg. Any other types of rolls or rolls made from different materials, or those falling outside this weight bracket, would be classified elsewhere within the HTS.
