Import Tips & Compliance
• Provide USP/EP certificate of analysis confirming ≥94% purity and low heavy metals for FDA/CBP scrutiny
• Declare as 'dipentaerythritol ≥94%' explicitly; vague 'polyol' descriptions risk 3824 classification
• Use child-resistant packaging if destined for pharma to meet import safety standards
