Import Tips
• Verify purity and provide Certificate of Analysis (COA) to confirm classification as a chemically defined compound under Chapter 29
• Ensure REACH/SVHC compliance for EU imports; TPP is listed on candidate lists in some regions
• Label with CAS 115-86-6 and GHS hazard pictograms to avoid customs delays
