1521.90 - Other:

This HTS category, 1521.90, encompasses "Other" animal or vegetable waxes, as well as beeswax, other insect waxes, and spermaceti. It serves as a catch-all for these natural waxes that do not fall under the specific classification for vegetable waxes (1521.10.00). The scope includes these waxes whether they have undergone refining processes or have been colored.

The primary distinction between 1521.90 and its sibling category 1521.10.00 lies in the origin and specific type of wax. While 1521.10.00 is exclusively for vegetable waxes derived from plants, 1521.90 broadens to include waxes produced by insects (beeswax and other insect waxes) and the fatty wax substance found in the head cavities of the sperm whale (spermaceti), in addition to any residual vegetable waxes not specifically classified.

To provide further detail and facilitate precise classification, this category is further subdivided. The subcategory 1521.90.20.00 specifically addresses "Bleached beeswax," indicating a processed form of beeswax that has undergone a decolorization treatment. The remaining waxes and any unbleached or otherwise processed forms not covered by the "bleached beeswax" designation are then captured under the broader "Other" subcategory, 1521.90.40.00.
