Import Tips
• Verify purity certificate to confirm it's chemically defined magnesium hydroxide, not mixed with organics (which may shift to Chapter 38)
• Include safety data sheets (SDS) for hazardous material handling; common pitfall is mislabeling as fertilizer-grade
• Ensure packaging complies with DOT regulations for powders to avoid delays at ports
