7225.30.11.10 - Of high-speed steel

This HTS classification, 7225.30.11.10, specifically covers flat-rolled products of other alloy steel that are not further worked than hot-rolled, are in coils, have a thickness of 4.75 mm or more, and are made of high-speed steel. High-speed steel is a type of tool steel characterized by its ability to retain hardness at elevated temperatures, making it ideal for cutting tools and applications requiring high performance under stress. These products are manufactured from alloy steels other than stainless or silicon-electrical steels.

This category is distinguished from its sibling, 7225.30.11.80, by the specific composition of the alloy steel. While 7225.30.11.80 covers "Other" tool steels at this level, 7225.30.11.10 is exclusively for products identified as high-speed steel, indicating a more specific metallurgical composition with higher proportions of alloying elements like tungsten, molybdenum, vanadium, and cobalt. The width requirement of 600 mm or more and the hot-rolled, coiled form are common to both categories at this hierarchical level.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, the classification ends at the specific material designation of "high-speed steel" within the broader context of other alloy steel flat-rolled products. Classification decisions within this category would focus on verifying the chemical composition to confirm the presence of alloying elements characteristic of high-speed steel as per established metallurgical standards.
