Import Tips & Compliance
• GC assay confirming >98% ester content; declare as 'p-anisic acid ethyl ester' on invoice
• IFRA compliance for fragrance use; avoid food flavor declaration without FEMA GRAS status
• Distilled grade preferred; technical grade may contain alcohol/acid balance affecting classification
