Import Tips
• Provide assay certificates confirming ≥90% KOH content and solid pellet form to prevent reclassification as impure or liquid
• Ensure DOT/UN hazardous classifications (UN1813) with spill-proof drums; pitfalls include insufficient labeling causing customs delays
• Monitor for EU/US caustic soda/potash trade quotas; bulk imports often require advance EPA pre-notice for hazardous substances
