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
