7223.00.10 - Round wire

This category encompasses round wire manufactured from stainless steel. Stainless steel is characterized by its inherent corrosion resistance, typically achieved by the addition of chromium, and often nickel and other alloying elements. The "round" designation specifically refers to the wire's cross-sectional shape, distinguishing it from other forms. This classification applies to stainless steel wire of this specific circular profile, irrespective of its diameter or any surface treatments, provided it meets the criteria for stainless steel as defined within Chapter 72.

The primary distinction for this category lies in its shape. It is separate from sibling categories such as "Flat wire" (7223.00.50.00), which would cover wire with a rectangular or square cross-section, and "Other" (7223.00.90.00), which serves as a residual category for any stainless steel wire that is neither round nor flat. The latter part of the parent context, "IV. OTHER ALLOY STEEL; HOLLOW DRILL BARS AND RODS, OF ALLOY OR NONALLOY STEEL," indicates that this category is specifically for stainless steel wire and not for other types of alloy steel or specialized hollow products.

Within this classification of round stainless steel wire, further subdivisions exist to provide more granular detail. The subcategory "Spring round wire of a kind described in statistical note 8 to this chapter" (7223.00.10.05) accounts for round stainless steel wire specifically manufactured for spring production, often possessing particular tensile strength and elasticity properties as outlined in the relevant statistical note. The residual subcategory, "Other," then captures all remaining round stainless steel wire not meeting the specific criteria for spring wire, allowing for comprehensive classification.
