Import Tips
• Provide lab analysis reports confirming synthetic production method to differentiate from heading 2615 natural ores
• Declare metal content precisely per statistical notes; misreporting can lead to penalties or reclassification
• Check for CITES or ITSCOM restrictions if trace elements suggest conflict sourcing
