Its unique placement highlights its specialized nature and the particular trade or regulatory circumstances that apply to its importation.

As this is a leaf node, there are no further subcategories to explore. Classification at this level is definitive for the specified chemical compound. Importers should ensure that all documentation accurately reflects the HTS code 9902.06.90 and any applicable temporary legislation or trade agreement provisions associated with this particular item. Understanding its specific application as a UV absorber can aid in confirming its correct classification.
