Import Tips
• Include flash point and boiling point data in documentation to distinguish from general diphenyl oxide mixtures
• Verify 99%+ purity to avoid reclassification as mixtures under Chapter 38 if impurities exceed 1%
• Obtain end-use statements if imported for high-temperature applications to preempt industrial chemical reviews
