Import Tips

• Provide detailed chemical analysis (NMR, IR spectra) confirming sulfonation on hydrocarbon base structure to verify Chapter 29 classification

• Include Material Safety Data Sheets (MSDS) and UN shipping declarations for corrosive properties during customs clearance

• Ensure proper labeling as hazardous material (UN 3261) to avoid delays; verify purity levels as impurities may affect duty rates
