4008.29.20.00 - Profile shapes

This category encompasses profile shapes made from vulcanized rubber, excluding hard rubber. These are formed articles with a specific cross-sectional shape designed for a particular function, such as sealing, guiding, or protecting. Examples include rubber extrusions used in window seals, automotive weather stripping, gasket profiles, and custom-shaped trim pieces. The defining characteristic is their non-cellular nature and their presentation as formed shapes rather than flat sheets or simple rods.

Distinguishing this classification from its sibling category, "Other" (4008.29.40.00), is crucial. While "Other" serves as a residual category, this specific subheading is dedicated to *profile shapes* that are clearly identifiable by their distinct cross-sectional geometries. If a rubber product fits the description of a profile shape as described above, it should be classified here rather than under the general "Other" category for non-cellular rubber items at this level.

As this is a leaf node in the HTS classification, there are no further subcategories. The classification ends with this specific description of vulcanized, non-cellular rubber profile shapes. Therefore, careful consideration should be given to whether the imported article meets the definition of a profile shape as opposed to a simpler form or a product intended for a different classification.
