Import Tips & Compliance
• Verify composition meets non-refractory standards; refractory materials shift to 3816
• Include safety data sheets (SDS) and test reports for VOC content to comply with EPA regulations
• Avoid misclassification as ready-mixed concrete (3824.50.5050) by specifying dry powder form
