Import Tips
• Provide lab assay reports distinguishing sponge from powder to comply with subheading particle size note
• Use secure packaging to prevent loss; declare as hazardous material if pyrophoric properties present
• Monitor London Platinum Market quotes for valuation, as iridium trades separately from platinum
