Import Tips
• Confirm that the sulfonyl group does not render the product classifiable under organo-sulphur compounds (heading 29.30), as chapter note 6 excludes sulphonated derivatives from that heading
• Provide a technical data sheet showing the chemical structure and purity
• Ensure proper labelling for transport, as hydrazine derivatives may be regulated as hazardous goods
