3506.91.50.00 - Other

This HTS subheading, 3506.91.50.00, encompasses a broad range of adhesives that do not fall under more specific classifications within heading 3506. The defining characteristic is that these are prepared glues and adhesives, or products suitable for use as such, not elsewhere specified or included. Crucially, these must be presented in quantities not exceeding 1 kg for retail sale. The category is further defined by its adhesive base, which must be composed of polymers described in headings 3901 to 3913 or derived from rubber.

This classification is distinct from its sibling category, 3506.91.10.00, which specifically covers optically clear free-film adhesives and optically clear curable liquid adhesives designed exclusively for the production of flat panel displays or touch-sensitive screen panels. Therefore, 3506.91.50.00 applies to all other adhesives meeting the base material and retail packaging criteria that are not optically clear and intended for electronic display manufacturing.

As this is a leaf node in the HTS classification structure, there are no further subcategories. Classification under 3506.91.50.00 is determined by the absence of a more specific HTS provision, coupled with the presence of an adhesive base derived from the specified polymers or rubber, and adherence to the net weight limitation for retail sale. Examples of goods that might fall here include general-purpose craft glues, household repair adhesives, and DIY adhesive products packaged for consumer use.
