9902.08.92 - Barium magnesium aluminate phosphor doped by europium, of a kind used as a luminophore (CAS Nos. 102110-17-8,1304-28-5,1309-48-4, 1344-28-1,1308-96-9, and 63774-55-0) (provided for in subheading 3206.50.00)

This HTS classification, 9902.08.92, specifically covers barium magnesium aluminate phosphor doped with europium. This material is recognized for its luminescent properties and is intended for use as a luminophore, a substance that exhibits phosphorescence. The inclusion of specific CAS numbers helps to precisely identify the chemical composition and variations of this particular phosphor.

While the broader HTS system classifies a vast array of goods, this subheading falls under Chapter 99, which pertains to temporary legislation and trade modifications. This distinguishes it from general merchandise classifications found in earlier chapters. Specifically, it is a specialized provision, a temporary modification, as indicated by its placement within Chapter 99 and the parent context of "Special Classification Provisions." Its role is to address unique import situations or trade policy impacts related to this specific type of phosphor.

As a leaf node, 9902.08.92 does not have further subdivisions. Its purpose is to provide a distinct classification for this specialized material, which is explicitly stated to be "provided for in subheading 3206.50.00." This cross-reference indicates that while the material itself is classified here for temporary or specialized purposes, its underlying nature relates to pigments and preparations. This subheading serves as a specific carve-out or modification to how this particular phosphor is treated under customs regulations.
