Import Tips
• Verify that the lead monoxide content is accurately documented, as this may affect other regulatory requirements
• Confirm that the microspheres are not considered 'lead crystal' under subheading note 1, as that applies to specific subheadings, not 7018
• Provide safety data sheets for the lead content to facilitate customs clearance
