Overview
Chapter 29 of the Harmonized Tariff Schedule (HTS) broadly encompasses organic chemicals. Within this chapter, heading 2930 specifically covers organo-sulfur compounds. This category includes a diverse array of organic molecules where at least one sulfur atom is directly bonded to a carbon atom. These compounds are crucial intermediates and end-products across various industries, including pharmaceuticals, agriculture, and material science.
Unlike headings that classify inorganic chemicals or different classes of organic compounds such as alcohols or aldehydes, heading 2930 is solely dedicated to organic compounds featuring a carbon-sulfur linkage. For example, while heading 2931 covers other organo-inorganic compounds, 2930 focuses on organo-sulfur entities. This distinction is critical for accurate tariff classification.
The subcategories within 2930 provide further specificity based on the functional groups attached to the sulfur atom. For instance, subheadings differentiate between thiocarbamates and dithiocarbamates (2930.20), thiuram mono-, di-, or tetrasulfides (2930.30), and other specific organo-sulfur compounds like methionine (2930.40) and various thioethers (e.g., 2930.60 and 2930.70). The residual category, "Other" (2930.90), serves to capture any remaining organo-sulfur compounds not specifically enumerated in the preceding subheadings, ensuring comprehensive coverage within this heading.
