Hollow Brass Square Profile Rod
A hollow square profile rod made from copper-zinc base alloy (brass) used in architectural handrails and structural frameworks. It falls under HTS 7407.29.16 as a hollow profile of copper alloy, specifically brass where zinc predominates over other elements except copper. These profiles are extruded for strength and lightness in construction applications.

This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not hollow (solid profile)
Solid copper alloy profiles classify under 7407.22, while hollow ones go to 7407.29.16.
If further manufactured into tubes/pipes
Finished copper alloy tubes/pipes move to Chapter 74 heading 7411, not bars/profiles.
If imported as refined copper alloy bars before extrusion
Unwrought refined copper alloys (including billets for extrusion) classify under 7403.

Import Tips & Compliance
• Verify alloy composition meets brass definition (zinc > other elements, Ni <5%, Sn <3%) with mill test certificates to avoid reclassification
• Ensure profile dimensions qualify as 'hollow' per HTS notes; solid bars fall under 7407.22
• Declare exact cross-sectional shape and wall thickness to prevent undervaluation penalties
