Import Tips
• Classify as DOT hazardous material (ORM-D or proper shipping name); ensure MSDS/SDS and proper labeling for air/sea transport
• Verify EPA registration if containing regulated chemicals; provide proof it's a refill preparation, not a complete extinguisher
• Avoid misclassification as general chemical mixtures (3824); include manufacturer specs confirming fire extinguisher use
