Import Tips & Compliance
• Provide a certificate of analysis confirming 99.8% purity and the absence of impurities that could affect classification
• Specify the intended use in organic synthesis to avoid misclassification under dye intermediates
• Verify that the product is not put up in measured doses or for retail sale, which would shift classification to a later heading
