Import Tips
• Verify chemical composition certificates to confirm aromatic structure and purity levels required for 3402 classification
• Ensure proper hazardous material labeling and shipping documentation for corrosive liquids like LABSA
• Avoid misclassification as soap by confirming insolubility tests per Chapter 34 notes
