9902.08.91 - Lanthanum phosphate phosphor doped by cerium and terbium, of a kind used as a luminophore (CAS No. 95823-34-0) (provided for in subheading 3206.50.00).

This HTS code, 9902.08.91, specifically covers lanthanum phosphate phosphor that has been doped with cerium and terbium, and is intended for use as a luminophore. Luminophores are substances that emit light after being exposed to radiation. The provided CAS number (95823-34-0) serves as a definitive identifier for this particular chemical compound. This classification falls under Chapter 99, which denotes temporary legislation, modifications, or additional import restrictions.

While HTS codes are structured hierarchically, this specific code, being at the end of a particular branch within Chapter 99, does not have direct siblings in the traditional sense of product categories at the same level. Its uniqueness lies in its application of temporary or specific trade provisions rather than broad product classifications found in earlier chapters. The "provided for in subheading 3206.50.00" note indicates that the underlying commodity, when not subject to the temporary provisions of Chapter 99, would normally be classified under subheading 3206.50.00, which pertains to other inorganic colour lakes and preparations.

As this is a leaf node, there are no subcategories to introduce. The classification is specific to the described lanthanum phosphate phosphor and its intended luminophore use under the current temporary legislation or trade provision indicated by its Chapter 99 placement. This means that any goods entered under this code must meet the specific requirements or restrictions associated with that particular Chapter 99 provision.
