Import Tips & Compliance
• Confirm the sulfonic acid group does not make the product more specifically classifiable under organo-sulphur compounds of heading 29.30
• Provide the synthesis route and end-use to support classification as a quinone derivative
• Ensure the product is not put up in forms for retail sale, which would affect classification
