Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If prepared as inorganic pigment coloring matter for paints
Mixed or prepared pigments for specific uses like paints fall under Chapter 32 rather than pure chemical compounds.
If natural earth colors with <70% combined iron
Natural mineral products below the iron threshold are classified as earths and clays in Chapter 25.
If chemically modified or mixed with additives for specific formulations
Prepared chemical mixtures or preparations not purely chemically defined shift to Chapter 38.

Import Tips & Compliance
• Verify iron content via lab analysis to confirm >70% Fe2O3 for proper classification
• Provide Certificates of Analysis (CoA) showing chemical purity to avoid reclassification as lower-grade pigments
• Ensure packaging labels specify synthetic origin to distinguish from natural earth colors
