Import Tips
• Include GC-MS analysis certificates confirming >99% purity to prevent reclassification as mixtures
• Declare stabilizer content explicitly; added stabilizers per Chapter 29 note 2(f) don't change heading but require disclosure
• Comply with TSCA import certification; DBP requires EPA notification for significant new uses
