7411.29 - Other:

This HTS category, 7411.29, encompasses tubes and pipes manufactured from copper alloys, specifically excluding those primarily composed of copper-zinc (brass) or copper-nickel (cupro-nickel or nickel-silver). It serves as a residual category for all other copper alloy tubes and pipes not explicitly defined by their specific alloy composition at the 7411.21 and 7411.22 subheadings. The key differentiating factor here is the absence of the principal alloying elements that define its sibling categories.

To accurately classify under 7411.29, the material composition of the tubes and pipes must be confirmed to be a copper alloy other than brass or cupro-nickel/nickel-silver. This means that if the copper alloy's primary constituents are elements like tin, aluminum, or silicon in combination with copper, and the brass or cupro-nickel/nickel-silver content is not dominant or defining, then classification under this subheading is appropriate.

This category is further subdivided to distinguish between manufacturing methods. Subheading 7411.29.10.00 covers seamless tubes and pipes made from these "other" copper alloys, meaning they are formed without the creation of a weld seam. In contrast, subheading 7411.29.50.00 encompasses all other tubes and pipes within this category, which would typically include those that are welded or otherwise fabricated through methods that result in a seam.
