Import Tips
• Include end-use statement specifying photographic grade to support classification and any quota applicability
• Ensure EP1 (EPA) certification if containing reportable chemicals; test for heavy metals to meet purity standards
• Ship in moisture-proof bags; exposure to air can form hydrates, risking reclassification
