7205.21.00.00 - Of alloy steel

This HTS category, 7205.21.00.00, specifically covers powders derived from iron or steel that are classified as being of an alloy steel composition. This means the powders must contain one or more alloying elements, such as chromium, nickel, molybdenum, or vanadium, in quantities that impart specific properties to the resulting alloy steel. The granular form of these materials is a key characteristic, differentiating them from solid forms of alloy steel.

This classification is distinguished from its sibling category, 7205.29.00.00, "Other," by the explicit requirement that the powders be of alloy steel. The sibling category would encompass iron or steel powders that do not meet the defined criteria for alloy steel, such as powders of plain carbon steel or pig iron without significant alloying elements. Therefore, the presence and nature of alloying elements are the primary determinants for classifying powders under 7205.21.00.00.

As this is a leaf node in the HTS classification system, there are no further subcategories. The scope of this heading is limited to alloy steel powders, and classification within this specific code is determined by the composition of the powder. For practical classification, importers and exporters should refer to the definition of alloy steel as per Chapter 72 notes and relevant international standards to confirm the presence and quantity of alloying elements.
