Import Tips
• Provide lab reports on polymer content to confirm chemical preparation status and avoid Chapter 25 cement classification
• Label containers clearly as 'wet mix - use within 2 hours' to demonstrate state at import
• Check for VOC compliance certifications, as polymer additives may trigger environmental regulations
