Import Tips
• Document the purity level (≥99.99%) with a certificate of analysis to support the classification
• Ensure the product is not dissolved in a solvent that makes it particularly suitable for a specific use, which could change classification
• Declare the product as HPTA on customs documents to avoid confusion with industrial grades
