Import Tips
• Pre-crush sieve testing documentation prevents reclassification to 7102.10 powder subheadings
• Specify 'not suitable for gem working' in commercial invoice to reinforce industrial classification
• Watch for CBP challenges on carbonado vs. synthetic cubic boron nitride misidentification
