Is perilla leaf oil supply seasonal, and how do you manage year-round availability?
Yes — raw material is seasonal (summer harvest, July–September), but we maintain a year-round strategic stock plus early-harvest contracts to guarantee continuous supply.
Seasonality & Supply Management
| Period | Activity |
|---|---|
| July–September | Peak harvest of fresh purple leaves; main production window |
| October–June | Processing of stocked raw material; strategic finished-oil stock covers demand |
| Off-season large orders | Scheduled against carried stock; lead time may extend 1–2 weeks |
- We sign advance-purchase contracts with Dao-di farms (Heilongjiang Suihua, Inner Mongolia Chifeng, Gansu Dingxi) to secure fresh purple-leaf volume
- Finished oil is stored in sealed aluminum drums under 15–25°C controlled conditions
- For long-term buyers we recommend an annual stock plan to smooth out seasonal price and availability swings
