HS Code for Lithopone

Lithopone is a white pigment consisting of a mixture of zinc sulphide and barium sulphate, classified under HS code 3206.42. This code falls under the broader category of other coloring matter and preparations. The classification is specific to pigments and preparations based on zinc sulphide. Lithopone is produced through a precipitation process and is widely used in the paint, ink, and plastics industries due to its opacity and chemical stability. The HS code 3206.42 is used because the product is a prepared pigment rather than a pure chemical compound found in Chapter 28. The technical specifications of the mixture, particularly the ratio of zinc sulphide, are critical for determining the correct classification within the 3206 heading. Lithopone is valued for its low cost and high resistance to yellowing compared to other white pigments. In the context of the Harmonized System, it is grouped with other inorganic coloring matters that are not specified in more specific headings like 3206.11 (titanium dioxide). The classification ensures that the product is treated as a pigment preparation for industrial use.

Common Misclassification

Lithopone is sometimes misclassified under 2830.10 (sodium sulphides) or other pure sulphides in Chapter 28. However, because it is a mixture used as a pigment, it must be in Chapter 32. It is also confused with titanium dioxide pigments (3206.11), which are the most common white pigments but have a different chemical base. Another error is 3206.49, the general category for other coloring matter, which should only be used if the specific code 3206.42 for lithopone is not applicable.

FAQ

What is the HS code for Lithopone?

The HS code for Lithopone and other pigments based on zinc sulphide is 3206.42.

Is Lithopone considered a hazardous chemical for shipping?

While Lithopone itself is generally stable, its classification for transport depends on the specific formulation and local regulations, though its HS code remains 3206.42.
