7405.00.60.30 - Beryllium copper master alloy

This HTS category, 7405.00.60.30, specifically covers master alloys of copper that are composed of copper and beryllium. Master alloys are pre-alloyed mixtures of metals, often with higher concentrations of one or more alloying elements than typically found in the final product. In this instance, it refers to the concentrated mixture of copper and beryllium intended for further processing or alloying into finished beryllium copper products, such as high-strength springs, electrical connectors, and other components requiring excellent conductivity, strength, and corrosion resistance.

Within the broader category of "Other" master alloys of copper (7405.00.60), this specific sub-classification distinguishes itself by the presence of beryllium as the primary alloying element. Other sibling categories at this level may cover master alloys with different primary alloying elements, or those that do not fit into more specific, pre-defined master alloy classifications. The key differentiator here is the precise elemental composition, focusing solely on copper-beryllium mixtures.

As this classification represents a leaf node within the HTS structure, there are no further subcategories to introduce. Classification at this level is determined by the definitive presence of beryllium as the alloying element in a master alloy of copper, distinguishing it from other master alloys based on different metallic components or general "other" categories.
