2813 - Sulfides of nonmetals; commercial phosphorus trisulfide:

This HTS category, 2813, encompasses specific chemical compounds characterized as sulfides of nonmetals, with a particular inclusion for commercial phosphorus trisulfide. These substances are inorganic in nature and are primarily utilized in various industrial applications, including the production of chemicals, pesticides, and as vulcanizing agents in the rubber industry. The classification falls within Section VI, Chapter 28, which deals with a broad range of inorganic chemicals, highlighting the chemical and industrial significance of these nonmetal sulfides.

Distinguishing this category from its siblings at the HTS database root level is crucial for accurate classification. Unlike the live animal classifications (Chapters 0101 through 0105) or other broad categories of raw materials and manufactured goods, HTS 2813 is exclusively concerned with specific inorganic chemical compounds. Its placement within Chapter 28 further differentiates it from organic chemicals or finished manufactured products, focusing solely on the elemental and compound nature of these sulfides.

Within HTS 2813, further subdivisions exist to provide more granular classification. The subcategory 2813.10.00.00 specifically covers carbon disulfide, a widely used industrial solvent and chemical intermediate. The remaining entries under the "Other" designation (2813.90) account for other sulfides of nonmetals not specifically enumerated elsewhere within this heading, as well as commercial phosphorus trisulfide. This hierarchical structure allows for precise identification based on the chemical composition and specific type of nonmetal sulfide.
