Technical parameters
Prune specification — what needs to be defined.
The specification is the document goods are produced, accepted and claimed against. Every parameter in it carries a consequence for price, shelf life and channel fit.

What makes up a prune specification?
A specification covers calibre, moisture, pitting, quality class, tolerances, packaging and the documentation required by the destination market. Calibre and moisture are the parameters that most often differ between offers, which is why two seemingly equal prices are frequently not comparable.

Parameters and where they are defined
The table lists each parameter and the standard that governs it. Values for a specific batch are confirmed in the specification accompanying a quotation, not published in advance.
| Parameter | What it determines | Reference |
|---|---|---|
| Calibre | Fruit size and intended use | UNECE DDP-07, count per 500 g |
| Moisture | Texture, weight and storage | UNECE DDP-07: maximum 40%; batch target belongs in the specification |
| Pitting | Format, processing and application | Pitted or unpitted; both presentations may be Class I or Class II |
| Uniformity | Consistency across a consignment | Tolerances set by the standard |
| SO₂ | Recipe and allergen labelling | EU maximum 2,000 mg/kg; above 10 mg/kg must be declared |
| Packaging | Logistics and sales channel | Bulk carton, sack, big bag or retail format |
| Documentation | Market acceptance | Analyses and certificates per destination country |
In detail
Parameter by parameter
Each parameter has its own page explaining the standard, the reference tables and what it means for your sourcing decision.
Moisture and shelf life
Permitted moisture ranges by product type and how moisture sets shelf life and storage conditions.
Pitted or unpitted
Differences in processing, moisture and quality classes, and which format suits which sales channel.
Quality and SO₂
Sulphur dioxide, European Union limits, allergen labelling and the documents accompanying a shipment.
