3205.00.50.40 - Blue

This HTS subheading, 3205.00.50.40, specifically classifies "Blue" color lakes and preparations based on them. These products are essentially insoluble pigments derived from soluble dyes, fixed onto an inert inorganic substrate. Their primary function is to impart a blue coloration to various materials and products. This category falls under the broader heading of color lakes and related preparations, situated within Chapter 32 of the Harmonized Tariff Schedule, which deals with tanning or dyeing extracts and pigments.

Distinguishing this subcategory from its siblings, it is crucial to note that 3205.00.50.40 is exclusively for blue colorants. Other subcategories at this level, such as 3205.00.50.10 (Yellow), 3205.00.50.20 (Red), and 3205.00.50.30 (Violet), are designated for pigments and preparations exhibiting those specific colors. The "Other" sibling category, 3205.00.50.50, is reserved for color lakes and preparations that do not fall under the specific color designations (Yellow, Red, Violet, or Blue) of the preceding subheadings.

As this is a leaf node within the HTS classification system, there are no further subcategories branching from 3205.00.50.40. Therefore, the focus remains on the precise identification of goods as "Blue" color lakes or preparations based on blue color lakes. Classification into this subheading relies on the inherent blue hue of the pigment or preparation, as well as its composition as a color lake or a preparation thereof, as defined by Note 3 to Chapter 32.
