3206.49.20.00 - Preparations based on iron oxides

This HTS subheading, 3206.49.20.00, covers preparations where iron oxides are the primary coloring matter. These preparations are utilized in various industrial applications to impart color, often serving as pigments in paints, inks, plastics, or construction materials. The key defining characteristic is the presence of iron oxides as the active coloring agent, distinguishing them from other inorganic colorants.

It is crucial to differentiate this classification from its siblings. For instance, 3206.49.10.00 specifically addresses concentrated dispersions of pigments within plastic materials, a distinct product form. Preparations based on zinc oxides (3206.49.30.00) and carbon black (3206.49.40.00) are categorized separately due to their different chemical compositions and inherent coloring properties. Furthermore, preparations based on hexacyanoferrates (3206.49.55.00) are also distinct. This subheading is reserved for iron oxide-based preparations not falling under those specific exclusions or classifications.

As this is a leaf node, there are no further subdivisions within 3206.49.20.00. Classification at this level is determined by the presence of iron oxides as the principal coloring component in a preparation, and the absence of specific characteristics that would place it into one of the aforementioned sibling categories. Practical classification will rely on analyzing the composition and intended use of the preparation to confirm the dominance of iron oxides as the coloring agent.
