7223.00 - Wire of stainless steel:

Category 7223.00 specifically covers wire manufactured from stainless steel. Stainless steel is characterized by its high chromium content, which provides excellent corrosion resistance. This category encompasses all forms of stainless steel wire, regardless of its cross-sectional shape, size, or finish, as long as the primary material is stainless steel.

This classification is distinct from other categories within Chapter 72, such as those for iron and steel bars, rods, or coils. While those categories might also involve iron and steel, 7223.00 is narrowly focused on products that have been drawn or otherwise processed into wire form. Furthermore, it is differentiated from general steel wire by the specific material composition – stainless steel – which imparts unique properties and often dictates its end-use.

The subcategories within 7223.00 further refine the classification based on the wire's cross-sectional shape. 7223.00.10 is designated for round wire, the most common form. 7223.00.50.00 is for flat wire, which has a rectangular or elliptical cross-section. The residual category, 7223.00.90.00, accounts for all other shapes of stainless steel wire not otherwise specified, providing a comprehensive classification for this product.
