HS Code for Inorganic luminophore

Inorganic luminophores are classified under HS code 3206.50. This code is part of Chapter 32, which covers tanning or dyeing extracts, tannins and their derivatives, dyes, pigments, and other coloring matter. Luminophores are synthetic inorganic products that, under the influence of an energy source such as ultraviolet light, X-rays, or electron beams, produce a luminous effect (fluorescence or phosphorescence). They are widely used in the manufacture of fluorescent lamps, cathode-ray tubes, and luminous paints. The classification depends on the chemical nature of the substance—it must be inorganic—and its specific function as a light-emitting agent. This distinguishes it from standard pigments that merely reflect light. According to the Explanatory Notes to heading 3206, these products are often metal sulfides (like zinc sulfide) activated by small amounts of other metals. They are classified here even if they are not intended for use as pigments, provided they are inorganic and function as luminophores.

Products Included

• Zinc sulfide activated with copper
• Calcium tungstate luminophores
• Inorganic fluorescent powders for lighting
• Phosphorescent inorganic compounds

Common Misclassification

Inorganic luminophores are frequently confused with organic luminophores, which are classified under HS code 3204.90. It is critical to determine the chemical base of the product to choose between 3204 and 3206. Additionally, they may be misclassified under Chapter 28 if they are seen as pure chemical compounds; however, Note 3 to Chapter 32 specifies that luminophores are included in 3206 regardless of their chemical purity.

FAQ

What is the HS code for Inorganic luminophore?

The HS code for inorganic products of a kind used as luminophores is 3206.50.

Are glow-in-the-dark paints classified here?

Finished paints containing luminophores are classified under HS code 3208, 3209, or 3210. HS code 3206.50 is for the luminophore substance itself before it is mixed into a paint binder.
