Import Tips
• Include ammonia content and dry rubber content (DRC) specs on commercial invoice; test for bacterial contamination common in transit
• Label containers with 'biodegradable hazard' if required; comply with TSCA for chemical notifications
• Avoid declaring as 'rubber solution' which implies solvents excluded from primary forms
