3204.20.10.00 - Fluorescent brightening agent 32

This HTS category, 3204.20.10.00, specifically covers a synthetic organic product identified as "Fluorescent brightening agent 32." These agents are designed to absorb ultraviolet light and re-emit it as visible blue light, thereby making materials appear whiter and brighter. Their application is typically found in industries such as textiles, paper manufacturing, and plastics.

Distinguishing this specific entry from its siblings, 3204.20.40.00 (Benzoxazol) and 3204.20.80.00 (Other), requires identifying the unique chemical composition or proprietary formulation of "Fluorescent brightening agent 32." While Benzoxazol represents a particular chemical class of fluorescent brighteners, and "Other" encompasses any not specifically listed, this code targets a distinct product with its own set of defining characteristics, likely based on a specific trade name or chemical structure not generically captured by the broader sibling categories.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, classification under 3204.20.10.00 is final for products meeting the criteria of "Fluorescent brightening agent 32." Importers and exporters should ensure that the product in question is precisely this identified agent to avoid misclassification.
