Is this wintersweet oil supply seasonal, and how should I plan my procurement?
Yes — the oil is strictly seasonal, following the winter flowering of wintersweet (December–February in central/southern China). Fresh blossoms are distilled within hours of harvest; stocked oil maintains year-round supply. Reserve volumes 3–6 months ahead for contract supply; certified volumes 6–9 months.
Seasonal Planning
| Supply window | Activity |
|---|---|
| Dec–Feb | Winter harvest and distillation |
| Mar–Nov | Stocked-oil supply from storage |
| 3–6 months ahead | Reserve contract volumes |
| 6–9 months ahead | Certified volumes (organic, etc.) |
- The short winter window makes advance reservation essential for large volumes
- Stocked oil is stored per ISO 210:2023 to preserve quality
- Annual contracts anchor supply and price for the following season
