8455.90.80.00 - Other

HTS Code 8455.90.80.00 encompasses "Other" parts for metal-rolling mills and their rolls, which are not specifically enumerated elsewhere within the 8455.90 subheading. This category serves as a residual classification for components that are essential to the functioning of metal-rolling mill machinery but do not fall under the more specific descriptions of parts. Examples might include specialized tools, auxiliary equipment, certain types of fasteners, or wear parts not fitting the criteria of the sibling category.

This classification is distinct from HTS Code 8455.90.40.00, which specifically covers castings or weldments that individually weigh less than 90 tons and are intended for use in the machines of heading 8455. While both fall under "Other parts" for metal-rolling mills, 8455.90.80.00 is for all other miscellaneous components that are not castings or weldments meeting the specified weight criteria. It captures a broader range of items that contribute to the operation, maintenance, or efficiency of the rolling mill.

As this is a leaf node in the HTS structure, there are no further subcategories within 8455.90.80.00. Therefore, classification into this category requires careful consideration of the specific nature and function of the part in relation to the overall metal-rolling mill. Importers and exporters should ensure that the item in question is indeed a part of a metal-rolling mill and does not fit any more specific classification within the 8455 chapter or other relevant chapters.
