Import Tips
• Specify alkyl chain distribution (C9-C11) in COA to confirm IDDP identity versus Santicizer 141
• Provide plasticizer efficiency data demonstrating polymer compatibility for classification support
• Comply with Proposition 65 labeling if California destination due to potential reproductive toxicity
