Import Tips
• Include GC-MS analysis certificates proving ≥99% purity to avoid reclassification as technical grade
• Register under TSCA Premanufacture Notification if first import exceeds 10,000 lbs annually
• Monitor for inhibitor addition; stabilized versions may require verification they don't render product use-specific
