Import Tips
• Include chemical composition certificates confirming borosilicate from heading 7005 to justify classification
• Avoid importing with temporary fittings; even plastic protectors can trigger reclassification out of 7006
• Declare intended end-use carefully; lab glass may require additional FDA or safety certifications
