Import Tips

• Verify purity certificate (typically 98%+ Na2S2O8) to confirm classification as chemically defined peroxosulfate under Chapter 28 Note 1

• Include Material Safety Data Sheet (MSDS) highlighting oxidizing properties for DOT hazardous material compliance during import

• Avoid misclassification as general sulfates (2833.2x) by providing assay reports; common pitfall is bulk packaging mistaken for industrial mixtures
