Overview

This HTS category, 3404.90.51.10, specifically covers artificial waxes and prepared waxes that are derived from lignite which has undergone chemical modification. Lignite is a naturally occurring soft brown coal. When chemically modified, it is processed to alter its properties, making it suitable for use as a wax-like substance. These preparations are distinct from unmodified lignite or other forms of artificial waxes not originating from chemically altered lignite.

This classification is differentiated from its sibling category, 3404.90.51.50 ("Other"), by its specific material origin. While both fall under "Other" artificial and prepared waxes, 3404.90.51.10 requires the wax to be a product of chemically modified lignite. The sibling category would encompass other artificial or prepared waxes that do not meet this specific lignite-based criterion.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification within 3404.90.51.10 is determined by the definitive characteristic that the artificial or prepared wax is produced from chemically modified lignite. Examples might include certain synthetic waxes used in polishes, coatings, or as additives, where the primary component is chemically treated lignite.
