Is eucalyptus leaf oil supply seasonal?

Supply is year-round, but there is a natural harvest rhythm. Eucalyptus leaves can be cut through most of the year in our growing regions, with an oil-yield peak in late summer to autumn and a dip in the cold months.

Seasonal Supply Pattern

PeriodSupply status
Late summer - autumnPeak harvest; best yield and freshest oil
WinterReduced fresh-leaf intake; production runs from stored/processed stock
SpringNormal production resumes; stock levels rebuilt
Demand peaksCold/flu season and festive season drive respiratory-product demand in autumn-winter
  • The oil is stable enough that stock produced at peak harvest is used to cover the low season
  • We maintain buffer stock precisely so buyers do not experience a seasonal gap
  • For contract buyers, a fixed monthly release schedule protects you from seasonal price swings
  • Demand planning tip: place cough-drop / vapor-rub / diffuser oil orders 6-8 weeks before your cold-season launch
  • Weather anomalies (prolonged drought or rain) can shift yields — buffer stock and plantation diversification reduce this risk
