Import Tips & Compliance

• Certify epoxide value (typically 5.5-6.5 eq/kg) meets Chapter 39 definition via titration analysis

• Ship in original manufacturer drums to prove primary form, avoiding 'prepared' interpretations

• Watch for reclassification if viscosity modifiers exceed 5% pushing to 3824 preparations
