HS Code for Zinc sulfide pigment

Zinc sulfide pigments are classified under HS code 3206.42. This classification is situated within Chapter 32, which covers tanning or dyeing extracts, pigments, and other coloring matter. The classification is determined by the intended use and the chemical preparation of the substance. Heading 3206 is designated for "Other coloring matter; preparations as specified in Note 3 to this Chapter." Subheading 3206.42 specifically identifies lithopone and other pigments and preparations based on zinc sulfide. Lithopone is a white pigment consisting of a mixture of zinc sulfide and barium sulfate. The classification follows GRI 1 and GRI 6, ensuring that the product is categorized based on its chemical identity as a prepared pigment. Unlike pure chemical compounds, these pigments are often mixed with extenders or carriers to facilitate their use in paints, plastics, and inks. The inclusion of zinc sulfide in Chapter 32 rather than Chapter 28 (Inorganic Chemicals) is due to its preparation for use as a coloring agent.

Products Included

• Lithopone (mixture of zinc sulfide and barium sulfate)
• Pure zinc sulfide prepared as a pigment
• Zinc sulfide-based masterbatches for plastics
• White coloring preparations for rubber manufacturing
• Zinc sulfide dispersions for industrial coatings

Common Misclassification

Zinc sulfide pigments are frequently misclassified under HS code 2830.90, which covers other sulfides. While pure zinc sulfide is a chemical compound that belongs in Chapter 28, once it is prepared for use as a pigment or mixed with other substances like barium sulfate, it must be classified under 3206.42. Another common error is confusing it with titanium dioxide pigments, which fall under 3206.11. Accurate classification requires verifying the chemical composition and the presence of additives that define the product as a pigment rather than a laboratory-grade chemical.

FAQ

What is the HS code for Zinc sulfide pigment?

The HS code for zinc sulfide pigment, including lithopone, is 3206.42.

Is pure zinc sulfide classified under the same code?

No, pure zinc sulfide as a separate chemically defined compound is classified under HS code 2830.90. It only moves to 3206.42 when prepared as a pigment.
