2621.10.00.00 - Ash and residues from the incineration of municipal waste

This HTS classification, 2621.10.00.00, specifically covers ash and residues derived from the incineration of municipal waste. This includes the solid byproducts generated after household and similar waste has been combusted in municipal incinerators. The material is typically characterized by its inorganic composition, often containing metals, glass, ceramics, and inert materials that do not burn.

This category is distinguished from its sibling, 2621.90.00.00 ("Other"), by the distinct origin of the ash. While 2621.90.00.00 would encompass other types of ash and slag, such as seaweed ash (kelp) or residues from industrial processes not specifically identified elsewhere, 2621.10.00.00 is exclusively reserved for materials originating from the incineration of common municipal refuse.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the classification criteria focus solely on identifying the material as ash or residue resulting from the incineration of municipal waste. Customs officers will rely on documentation and potentially physical inspection to confirm the origin and composition of the goods to ensure accurate classification under this heading.
