4501.90.20.00 - Waste cork

This HTS category, 4501.90.20.00, encompasses waste cork. This includes any cork material that is no longer suitable for its original purpose or has been produced as a byproduct of cork processing, and is not otherwise processed into a distinct form like crushed or ground material. Examples may include shavings, cuttings, or discarded portions of natural cork.

This category is specifically distinguished from its sibling category, 4501.90.40.00 (Crushed, granulated or ground cork). While both relate to processed cork, this category is for waste cork in a less processed state, whereas 4501.90.40.00 is for cork that has undergone specific size reduction processes to create distinct granular forms. The key differentiator lies in the physical form and degree of processing.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification within 4501.90.20.00 is determined by the material being waste cork and not falling under the specifically defined categories for crushed, granulated, or ground cork.
