7506.20 - Of nickel alloys:

This HTS category, 7506.20, specifically covers plates, sheets, strip, and foil made from nickel alloys. These are forms of nickel that have been combined with one or more other elements to enhance their properties, such as strength, corrosion resistance, or heat tolerance. The classification is determined by the material composition, focusing on products where nickel is a primary component alloyed with other metals.

This category is distinct from its sibling, 7506.10, which exclusively covers plates, sheets, strip, and foil made of pure nickel, meaning nickel not alloyed with other metals. Therefore, the presence of alloying elements is the key differentiator for classifying goods under 7506.20.

Within this category, further subdivisions exist based on the physical dimensions. The subcategory "Not exceeding 0.15 mm in thickness" provides a specific classification for very thin forms of nickel alloy plates, sheets, strip, and foil. The subsequent "Other" subcategory captures all nickel alloy plates, sheets, strip, and foil that do not meet this precise thickness limitation, allowing for a comprehensive classification of the various forms and dimensions of these products.
