Import Tips
• Include structural formula and CAS number (10197-20-0) on commercial invoice to confirm derivative status under guaiacol heading
• Verify no halogenation or sulfonation that might shift classification to earlier derivative subheadings per chapter notes
• Obtain prior FDA notification if destined for drug manufacturing to avoid customs holds on pharmaceutical precursors
