3204.17.60.20 - Pigment blue 15:4 🖩

This HTS category encompasses "Pigment blue 15:4," a specific type of synthetic organic coloring matter. As a pigment, it is an insoluble colored substance used to impart color to various materials. The "15:4" designation refers to a particular crystalline form or isomer of copper phthalocyanine blue, known for its distinct color properties and application characteristics, often related to improved dispersibility or color saturation compared to other forms.

Distinguishing this subcategory from its siblings, "Pigment blue 15" (3204.17.60.05) represents the base pigment, while "Pigment blue 15:1" (3204.17.60.10) and "Pigment blue 15:2" (3204.17.60.15) denote other specific polymorphic forms or modifications of the same basic pigment. This category, "Pigment blue 15:4," isolates a further refined or specialized variant, where the numerical designation is critical for precise classification based on its unique physical and chemical properties relevant to its intended use. The "Other" category (3204.17.60.85) serves as a residual for any other copper phthalocyanine blue pigments not otherwise specified.

As this classification represents a leaf node, there are no further subcategories. Therefore, the focus for classification within this item lies on confirming that the imported product is indeed Pigment blue 15:4, with its characteristic chemical structure and properties, distinct from the other specified forms of Pigment blue 15. Importers should ensure their documentation accurately reflects the specific designation of the pigment being declared to facilitate accurate customs processing.
