Import Tips
• Verify purity and composition via ISO 3405 distillation tests to confirm >50% butylene content for classification
• Obtain Material Safety Data Sheets (MSDS) and ensure cryogenic storage compliance during transport
• Avoid misclassification as propane/butanes (2711.13) by providing detailed hydrocarbon analysis certificates
