Import Tips
• Include distillation logs showing iso-butanal <0.5% to substantiate normal isomer classification
• Use stainless steel IBCs (Intermediate Bulk Containers) rated for corrosive aldehydes per UN specifications
• Pre-clear TSCA certification to avoid EPA import notifications for new chemical substances
