HS Code for Massicot

Massicot is classified under HS code 2824.10 because it is a specific form of lead monoxide (PbO). In the Harmonized System, Chapter 28 covers inorganic chemicals, and heading 2824 is dedicated specifically to lead oxides, including red lead and orange lead. Massicot is the yellow, orthorhombic modification of lead monoxide, typically obtained by heating lead in a furnace at temperatures below the melting point of the oxide. Because it is a chemically defined inorganic compound and not a prepared pigment or a metal alloy, it falls squarely into the subcategory for lead monoxide. The classification is determined by General Interpretative Rule (GIR) 1, which dictates that classification is determined by the terms of the headings and any relative section or chapter notes. Since 2824.10 explicitly mentions lead monoxide, and massicot is a mineralogical and chemical form of that substance, this code is the most specific and accurate designation for international trade and customs purposes.

Products Included

• Massicot (yellow lead monoxide)
• Litharge (red lead monoxide)
• Lead protoxide
• Plumbous oxide

Common Misclassification

Massicot is frequently misclassified under HS code 2824.90, which is the residual category for other lead oxides such as red lead (minium) or orange lead. While related, 2824.10 is the specific provision for lead monoxide. Another common error is using HS code 3206.49 for inorganic coloring matter; however, unless the massicot is specifically prepared as a pigment with binders or additives, it remains in Chapter 28. Additionally, it should not be confused with unwrought lead under heading 7801, which refers to the metal itself rather than the chemical oxide.

FAQ

What is the HS code for Massicot?

The HS code for Massicot is 2824.10, which covers lead monoxide (litharge and massicot).

Is there a difference between Massicot and Litharge in the HS system?

No, both Massicot and Litharge are chemical variations of lead monoxide (PbO) and are both classified under the same subheading, 2824.10, as they share the same chemical formula despite different crystal structures.
