Is Chuanxiong rhizome oil supply seasonal? When should I plan my orders?
Yes, Chuanxiong supply is seasonally driven by the Sichuan harvest. Planning orders ahead of the season keeps pricing stable and avoids lead-time delays.
Seasonality
| Period | Situation |
|---|---|
| Late summer (Jul–Aug) | Rhizome harvest in Sichuan; new-season raw material enters |
| Autumn (Sep–Nov) | New-oil production ramps up; best time to lock annual contracts |
| Winter–Spring (Dec–May) | Steady supply from stored stock; prices may edge up late season |
| Summer (Jun) | Old stock thinning; order early to avoid gaps |
- New-season oil typically offers the freshest phthalide profile (highest ligustilide)
- We recommend confirming annual volumes in Q3 (Aug–Sep) to lock pricing and priority production slots
- Safety stock is maintained, but certified and CO2 premium grades have tighter seasonal windows
