4821 - Paper and paperboard labels of all kinds, whether or not printed:

HTS Code 4821 encompasses a diverse range of labels manufactured from paper and paperboard. These include, but are not limited to, hang tags, self-adhesive labels (provided the backing material is paper or paperboard), price tags, and identifying labels for various products, regardless of whether they bear any printing. The defining characteristic for this heading is the material composition – primarily paper or paperboard – and their function as labels for marking, identifying, or decorative purposes.

While HTS Code 4821 deals with paper-based labels, it is crucial to distinguish it from other headings that might involve similar items made from different materials. For instance, labels made from plastics, textiles, or metals would fall under different HTS chapters and headings based on their primary constituent material. Furthermore, this heading specifically addresses "labels" in their finished form. Unprocessed paper or paperboard intended for label manufacturing would be classified under earlier headings within Chapter 48.

Within HTS Code 4821, further distinctions are made based on the presence of printing. Subheading 4821.10 specifically covers labels that are printed, meaning they bear text, images, or designs. In contrast, subheading 4821.90 is designated for "Other" labels, which are unprinted or may bear only a simple identifier without elaborate graphics. This subdivision allows for a more granular classification based on the level of manufacturing and customization applied to the labels.
