Import Tips
• Verify purity and ensure chemical analysis certificates confirm sulfonated aromatic structure per chapter 29 notes
• Include safety data sheets (SDS) showing it's not rendered for specific use beyond general surfactant applications
• Avoid misclassification as finished cleaning products; import as bulk chemical to prevent chapter exclusions
