8455.30.00.25 - Exceeding 6,803.9 kg

This HTS category encompasses rolls for metal-rolling mills that are manufactured from gray iron and have a weight exceeding 6,803.9 kilograms. These large, heavy-duty rolls are specifically designed for industrial metal processing operations requiring substantial material deformation and strength. Their application is typically found in heavy manufacturing sectors where the rolling of thick metal plates, beams, or structural components is performed.

This classification is distinguished from its sibling categories by its specific weight threshold. Unlike rolls "not exceeding 2,268 kg" (8455.30.00.05) or those "exceeding 2,268 kg but not exceeding 6,803.9 kg" (8455.30.00.15), this category exclusively covers gray iron rolls that surpass the 6,803.9 kg mark. This precise weight differentiation is a critical factor for accurate customs declaration and tariff application.

As this is a leaf node within the HTS classification system, there are no further subcategories. Therefore, classification into this specific code is determined solely by the material (gray iron), the function (rolls for rolling mills), and the precise weight exceeding 6,803.9 kg. Importers and exporters should ensure that the weight of the gray iron rolling mill rolls is accurately documented to align with this classification.
