Import Tips
• Confirm n-propyl vs isopropyl configuration via NMR spectra in supporting documentation
• Register with TSCA for commercial chemical import and maintain 90-day pre-manufacture notice if applicable
• Use temperature-controlled packaging to prevent decomposition during ocean freight transit
