Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for use primarily in rubber compounding
Rubber-specific stabilizers fall under 3812.39.60 even if chemically identical to plastic versions.
If marketed as pigment dispersant stabilizer
Synthetic organic coloring matter preparations use different classification in Chapter 32.
If in diluted solution form for industrial application
Chemical preparations in solvent shift to 3824 when not meeting specific compound criteria.

Import Tips & Compliance
• Provide manufacturer's specification sheet confirming CAS 41556-26-7 identity and >98% purity
• Classify as Environmentally Hazardous Substance per IMDG Code 9.1 for ocean transport
• Avoid common pitfall of declaring as 'plastic additive' which triggers 3824 reclassification
