关键要点
- Quality, not just availability, varies by season.
- Freight capacity and port performance are also seasonal.
- Coverage decisions should be made before the seasonal window closes.
Supply and quality seasonality
Harvest timing sets availability and, through growing and drying conditions, moisture and mycotoxin profiles. Late-season stock has been stored longer and carries different quality risk from new-crop material.
Logistics seasonality
Monsoon, ice-affected navigation, harvest-period truck shortages and holiday closures all compress capacity at predictable times. Planning around them is straightforward once they are on the procurement calendar.
需要核查的内容
- Seasonal supply calendar documented per ingredient and origin
- Quality expectations adjusted for old-crop versus new-crop material
- Coverage decision dates set ahead of seasonal windows
需管理的风险
- Buying into a seasonal price peak because cover was left late
- Elevated mycotoxin risk in a poor harvest year
- Freight capacity unavailable at a predictable seasonal peak
常见错误
- Treating an ingredient as available year-round without checking
- Applying new-crop quality assumptions to old-crop material
- Ignoring origin-country holidays in the calendar
常见问题
Does new-crop material always test better?
Not necessarily. New crop has had less storage exposure, but a difficult harvest can deliver new-crop material with higher moisture and greater mycotoxin risk than well-stored old crop.
How far ahead should seasonal cover be decided?
Before the window in which the material is available and freight can be secured — which is normally well before the price signal appears.
