Last updated: July 2026 dataA broad catch-all heading for inorganic coloring matter not covered by more specific headings, the US schedule subdivides 320649 into eight distinct tariff lines covering concentrated pigment dispersions in plastics (3206491000), iron oxide preparations (3206492000), zinc oxide preparations (3206493000), carbon black preparations (3206494000), hexacyanoferrate-based pigments such as Prussian blue (3206495500), cadmium compound pigments (3206496010), and two NESOI residual lines. Canada and Germany lead US supply across this diverse heading. The cadmium compound line (3206496010) warrants particular attention given potential TSCA and state-level restrictions on cadmium-containing materials.

If the product is a concentrated dispersion of pigment in a plastic material, it should be evaluated against 3206491000 (concentrated dispersions of pigments in plastic materials). However, if the plastic matrix is the essential character and the product functions primarily as a plastic compound rather than a colorant preparation, classification under Chapter 39 may be more appropriate. A binding ruling from CBP is advisable for high-volume masterbatch imports.
Cadmium compound pigments may be subject to TSCA review and are restricted or banned in certain end-use applications under state regulations (notably California Proposition 65). Importers should verify compliance with applicable federal and state chemical regulations before placing orders, and consult a licensed customs broker regarding any required certifications at entry.
