Import Tips
• Confirm it's a true lake via solubility tests; ultramarine is often borderline and CBP may challenge if not properly precipitated
• Include MSDS and technical data sheets proving chapter note 3 applicability, especially excluding tannin derivatives per note (b)
• Avoid bulk shipments without stabilization proof, as unstable pigments risk reclassification to inorganic pigments under 3206 if luminophore-like
