Import Tips
• Provide stabilization agent details (e.g
• pentene inhibitor) in import docs as allowed under Chapter 29 note (f) without changing classification
• Confirm product meets 'chemically defined' criteria with GC-MS analysis to prevent reclassification as a mixture
• Check for phase-out restrictions under Montreal Protocol; some countries ban imports of ozone-depleting substances like methylchloroform
