Import Tips
• Provide structural formula and ester confirmation via NMR or HPLC in import docs to distinguish from free acid (2918.19.1100)
• Check for ethyl alcohol ester classification per note 5(B), ensuring no conflict with heading 2905 for simple alcohols
• Declare exact purity to avoid duty escalation if impurities exceed incidental levels allowed in chapter note (a)
