Import Tips

• Verify purity certificates (typically ≥99%) as impurities may affect classification under Chapter 29 note (a)

• Include CAS number 108-01-0 and protonation status in commercial invoices to avoid misclassification

• Check REACH/ TSCA registration for US import; protonated salts require pH and counterion documentation
