Import Tips
• Provide GC-MS analysis confirming >98% cycloheptane purity to avoid reclassification as chemical mixture
• Label containers with UN 2241 hazardous material markings; ensure temperature-controlled shipping below 50°C flash point
• Maintain certificates of origin distinguishing synthetic cycloheptane from petroleum cycloparaffins
