Import Tips
• Verify surfactant concentration meets 0.5% water test for surface tension reduction per Chapter notes to avoid reclassification
• Provide Safety Data Sheets (SDS) and purity certificates; common pitfall is mislabeling as soap leading to 3401 duties
• Ensure CAS number documentation (e.g
• 27176-87-0) for customs verification of synthetic composition
