2802.00.00.00 - Sulfur, sublimed or precipitated; colloidal sulfur

This HTS category, 2802.00.00.00, encompasses elemental sulfur in its various refined forms. Specifically, it covers sulfur that has undergone sublimation, a process where solid sulfur is converted directly into a gas and then re-solidifies, resulting in a fine powder. It also includes precipitated sulfur, which is formed through a chemical reaction, and colloidal sulfur, a suspension of very fine sulfur particles in a liquid or solid medium. These forms are distinguished by their physical state and the methods of their production.

In the context of the Harmonized Tariff Schedule, this category is situated within Chapter 28, which deals with inorganic chemicals. Unlike its sibling categories, which primarily cover live animals (Chapters 01 through 05), and other diverse product groups, 2802.00.00.00 is strictly limited to sulfur as a chemical element. It is distinct from sulfur ores or crude sulfur, which are classified elsewhere and have not undergone the refinement processes indicated by sublimation or precipitation.

As this is a leaf node within the HTS classification system, there are no further subcategories. Therefore, classification under 2802.00.00.00 depends solely on whether the imported product is identified as sublimed, precipitated, or colloidal sulfur. Importers should ensure that documentation accurately reflects the form of sulfur presented, aligning with the specific characteristics of these refined sulfur products.
