7508.90 - Other:

HTS code 7508.90 encompasses "Other" articles of nickel that are not specifically enumerated in the preceding subheadings of heading 7508. This category serves as a residual classification for finished or semi-finished goods made primarily of nickel, which do not fall under more specific descriptions within the chapter. Examples might include nickel foils, plates, or sheets that are further processed beyond their initial form, or nickel alloys shaped into specific articles.

This subheading distinguishes itself from its sibling, 7508.10.00.00, which specifically covers cloth, grill, and netting manufactured from nickel wire. Therefore, 7508.90 would not apply to woven or knitted nickel wire products, but rather to articles where nickel is the predominant metal and the form or fabrication method differs significantly from woven wire structures.

Within the 7508.90 category, two subcategories exist to further refine classification. 7508.90.10.00 is designated for stranded wire, which consists of multiple individual nickel wires twisted or braided together. The remaining "Other" articles are then classified under 7508.90.50.00, capturing all other nickel articles not otherwise specified. This hierarchical structure ensures precise classification based on the specific form and construction of the nickel article.
