Synthetic Red Iron Oxide Pigment
Synthetic red iron oxide pigment (CI Pigment Red 101) is a high-purity, finely milled powder containing over 70% combined iron as Fe2O3, used primarily in paints and coatings. It falls under HTS 2821.10.0040 as a synthetic iron oxide pigment classified as 'other' within the synthetic pigments subheading. This classification applies to its chemically defined nature and pigment-grade particle size.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as earth colors rather than synthetic pigments
Natural earth colors with ≥70% Fe2O3 fall under the principal subheading, while synthetically produced versions are separated into the synthetic pigment subheading.
If when pre-mixed into finished inorganic color pigments or preparations
Mixtures of iron oxide with other substances for coloring use shift to Chapter 32 as prepared pigments, not pure chemical compounds.
If chemically modified or blended with organic additives for specific applications
Complex preparations or chemically defined reaction products of iron oxides with organics fall under chemical preparations in 3824.

Import Tips & Compliance
• Verify iron content exceeds 70% Fe2O3 equivalent via lab analysis for proper classification under 2821
• Provide Certificate of Analysis (CoA) showing synthetic production and pigment specifications to avoid misclassification as natural earth colors
• Ensure packaging labels purity, particle size (e.g
• 0.5-5 microns), and intended use to prevent scrutiny at customs
