Import Tips
• Provide GC-MS analysis confirming isononyl alcohol ester content to distinguish from linear chain phthalates
• Include end-use declarations avoiding toy applications due to phthalate content restrictions in many markets
• Monitor viscosity specs (typically 50-100 cP) as excessive thickening may trigger mixture classification
