4821.90.40.00 - Other

HTS code 4821.90.40.00 encompasses paper and paperboard labels of all kinds, which are not self-adhesive and do not fall under any other specific category within heading 4821. This typically includes labels that require an adhesive applied separately or labels that are affixed through other means, such as stitching, stapling, or being an integral part of the packaging itself. The key characteristic here is the absence of a pre-applied adhesive backing.

This category is distinct from its sibling, 4821.90.20.00 (Self-adhesive), which specifically covers labels with an integrated adhesive for direct application. Therefore, when classifying a label under 4821.90.40.00, the primary consideration is the method of attachment and the lack of inherent adhesive properties.

As a leaf node within the HTS structure, there are no further subcategories under 4821.90.40.00. Classification within this code relies on confirming that the product meets the general description of paper or paperboard labels and does not fit into any more specific provision, particularly the self-adhesive category. Examples could include swing tags, luggage tags, or labels intended for industrial application where a separate adhesive or mechanical fastening is used.
