Import Tips
• Provide ICP-MS metal analysis (<0.1 ppm total metals) and particle count certification for CBP review
• Use fluoropolymer-lined containers to prevent trace contamination affecting electronic purity specs
• Comply with ITAR/EAR if destined for semiconductor fabs with defense applications
