4504.10.10.00 - Vulcanized sheets and slabs wholly of ground or pulverized cork and rubber

This HTS category, 4504.10.10.00, specifically covers vulcanized sheets and slabs that are entirely composed of ground or pulverized cork combined with rubber. The vulcanization process imparts enhanced durability and flexibility to the material, making these sheets and slabs suitable for a range of industrial and specialized applications where both the properties of cork and rubber are desired.

It is important to distinguish this item from its siblings. For instance, 4504.10.20.00 pertains to insulation made from compressed cork, which may be coated, and 4504.10.30.00 and 4504.10.40.00 cover specific finished goods like floor and wall coverings, respectively. This category, 4504.10.10.00, focuses on the raw material form – sheets and slabs – as opposed to these end-use products. Furthermore, it differs from items classified under 4504.10.50.00 ("Other") which would encompass agglomerated cork products not otherwise specified.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification under 4504.10.10.00 is determined by the material composition (wholly ground or pulverized cork and rubber) and the form (vulcanized sheets and slabs), distinguishing it from other forms or compositions of agglomerated cork articles.
