7407.29.40.00 - Bars and rods of copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel silver)

This HTS category encompasses bars and rods specifically manufactured from copper-nickel base alloys, commonly known as cupro-nickel, and copper-nickel-zinc base alloys, also referred to as nickel silver. These alloys are distinguished by their distinct metallic composition, featuring copper as the primary metal with significant additions of nickel, and in the case of nickel silver, zinc as well. The physical form of these materials as bars and rods, characterized by their solid cross-sections and typically longer lengths, is crucial for their inclusion in this heading.

Within the broader heading for copper bars, rods, and profiles, this specific category differentiates itself from its sibling, "Profiles," by its defining shape. While profiles can encompass a wider range of cross-sectional forms (e.g., angles, channels), this classification is strictly limited to items with solid, uniform cross-sections in the form of bars or rods. It also stands apart from other "Other" bars and rods within this section by the specific alloy composition, excluding pure copper or other copper alloys not meeting the cupro-nickel or nickel silver criteria.

As this is a leaf node in the HTS structure, there are no further subcategories to explore under this specific code. Therefore, practical classification will rely on confirming the material composition of the bar or rod to be either a copper-nickel base alloy (cupro-nickel) or a copper-nickel-zinc base alloy (nickel silver), and verifying its form as a bar or rod, distinct from any profiles or other fabricated shapes.
