Import Tips
• Include chemical composition analysis showing borosilicate to leverage chapter note on fused quartz/silica
• Ensure declaration specifies 'not otherwise worked' to prevent reclassification to 7006 for profiled sheets
• Test for coatings; even thin reflecting layers could shift to specific 7004 subheadings if declared
