9902.08.95 - Barium magnesium aluminate phosphor doped by europium and manganese, of a kind used as a luminophore (CAS Nos. 102110-17-8 ,1344-43-0, 1304-28-5, 1309-48-4, 1344-28-1, 1308-96-9, and 63774-55-0) (provided for in subheading 3206.50.00)

This HTS category, 9902.08.95, specifically covers barium magnesium aluminate phosphors doped with europium and manganese. These specialized chemical compounds are primarily utilized as luminophores, meaning they emit light when exposed to certain forms of energy, such as ultraviolet radiation. The inclusion of specific CAS numbers in the description helps to precisely identify the chemical substances falling under this classification, differentiating them based on their exact composition and manufacturing.

As a category within Chapter 99, which deals with temporary legislation and special provisions, this classification likely represents a temporary duty rate or import restriction applied to these specific phosphors. It is crucial to note that the "provided for in subheading 3206.50.00" indicates the standard classification for these goods if no special provisions were in place. This HTS code essentially overlays a special provision onto the base classification, necessitating careful attention to the specific conditions or duty rates associated with 9902.08.95 during importation.

Since this is a leaf node, there are no further subcategories. The classification is precise and intended for a very specific type of phosphor. The key distinguishing factor from other goods would be its chemical composition (barium magnesium aluminate doped with europium and manganese) and its intended use as a luminophore, as opposed to other phosphors or chemicals that might fall under broader categories like general inorganic chemicals or pigments.
