3506.10 - Products suitable for use as glues or adhesives, put up for retail sale as glues or adhesives, not exceeding a net weight of 1 kg:

This HTS category, 3506.10, encompasses glues and adhesives that are specifically packaged for sale directly to consumers. The key criteria for inclusion are that the products must be suitable for use as glues or adhesives, presented in a retail-ready format, and their net weight must not exceed 1 kilogram. This ensures that these are typically consumer-sized quantities for household or small-scale crafting and repair purposes, distinguishing them from bulk industrial adhesives.

Within the broader scope of Chapter 35, which deals with albuminoidal substances, modified starches, glues, and enzymes, this HTS heading focuses on prepared adhesives. While its sibling category, often designated with a broader "Other" designation at the same level, might capture industrial or bulk preparations, 3506.10 is strictly limited to products offered for retail distribution in smaller units. This focus on packaging and intended end-user is a crucial differentiator for accurate classification.

The subcategories within 3506.10 further refine the classification based on the material composition of the adhesive. The primary subdivision, 3506.10.10.00, specifically addresses animal-based glues, including those derived from casein but excluding fish glue, which would fall under a separate classification. The remaining products that meet the retail sale and weight criteria, but are not animal glues, are directed to the "Other" subcategory, 3506.10.50.00, capturing synthetic glues and other adhesive formulations for consumer use.
