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
