Import Tips
• Verify purity levels and provide chemical analysis certificates to confirm classification as dipotassium carbonate under Chapter 28
• Include Safety Data Sheets (SDS) for hazardous material handling; it's hygroscopic and may require moisture-proof packaging
• Avoid misclassification as percarbonates; check for peroxides which shift to other subheadings
