U.S. exports of inorganic luminophores (HS 320650) totaled $2.6M in July 2026.
Importers of Inorganic Luminophores paid $45K in duties in July 2026 — an effective duty rate of 17% on $274K in dutiable value, based on actual customs collections rather than the published tariff schedule. Inorganic Luminophores imports of $274K in July 2026 ran 14% below the year-to-date monthly average of $319K.
Last updated: July 2026 dataInorganic products used as luminophores — phosphorescent and fluorescent materials that absorb and re-emit light — classify under a single US tariff line, 3206500000, and are critical inputs for LED phosphors, fluorescent lamps, display screens, and security printing. Japan leads US supply, reflecting that country's deep integration in advanced lighting and display component manufacturing, with Portugal and Germany also significant sources. The heading is distinct from organic fluorescent brightening agents (Chapter 32 elsewhere) and from radioactive luminescent compounds, which are governed by NRC regulations.

Inorganic luminophores (3206500000) are mineral-based compounds — typically rare-earth-doped oxides, sulfides, or silicates — that emit light upon excitation. Organic fluorescent brightening agents are carbon-based compounds that absorb UV and re-emit visible light, and they classify under heading 3204. The chemical nature (inorganic vs. organic) is the primary classification criterion.
A technical data sheet confirming the product's luminescent function — including excitation and emission spectra — supports classification under 3206500000. If the product is a pure rare-earth compound without a demonstrated luminophore application, it may classify under Chapter 28 instead. CBP has issued rulings on this distinction, and a binding ruling is recommended for novel phosphor formulations.
