Import Tips
• Include NMR or GC-MS spectra confirming structure as butylene oxide isomer to prevent misclassification as generic epoxides
• Use child-resistant packaging and include GHS labels for epoxide reactivity and flammability risks
• Avoid importing stabilized mixtures without verifying if stabilizers trigger classification under note (f) as preserved products
