Commodity Code
Description

Overview

Chapter 32 of the Harmonized Tariff Schedule (HTS) encompasses a broad range of materials used in coloring and finishing processes, including tanning or dyeing extracts, pigments, paints, and varnishes. Within this chapter, HTS code 3204 specifically addresses synthetic organic coloring matter, alongside certain synthetic organic products utilized for their fluorescent or luminescent properties. This category covers a wide array of dyes and pigments that are chemically synthesized, whether or not their exact chemical composition is defined. It also includes preparations incorporating these synthetic organic coloring matters, as outlined in note 3 to this chapter.

Distinguishing HTS 3204 from its sibling categories within Section VI involves recognizing its focus on *synthetic organic* chemical compounds used for color or fluorescence. While other chapters might deal with natural dyes, inorganic pigments, or finished products like textiles or plastics that contain coloring matter, HTS 3204 is dedicated to the raw, chemically defined or undefined synthetic organic substances themselves and their immediate preparations. This category specifically excludes natural coloring matter and inorganic pigments, which are classified elsewhere.

The subcategories under HTS 3204 provide further refinement based on the intended application or chemical nature of these synthetic organic products. The primary subdivision generally separates basic synthetic organic coloring matter and its preparations from those specifically designed as fluorescent brightening agents. This distinction is crucial for accurate classification, as fluorescent brightening agents, while synthetic organic products, have a specialized function of absorbing UV light and re-emitting it as visible blue light, thereby enhancing the whiteness or brightness of materials. The "Other" category captures any remaining synthetic organic coloring matters or related products not covered by the more specific subheadings.
