Import Tips
• Provide Certificate of Analysis (COA) confirming boron carbide composition and purity to avoid misclassification as mixtures
• Declare particle size and intended use (e.g
• abrasive) as boron carbide can be reclassified if processed for nuclear applications
• Check REACH/ TSCA compliance for industrial chemicals; boron carbide may require prior notice for bulk shipments
