Dried plum is one of the genuinely strong Ukrainian export categories, and it is built on a single variety family. The d’Agen type and its regional relatives dry to a soft, dark, high-sugar fruit that holds together, and the orchards in Vinnytsia, Khmelnytskyi, Cherkasy and the Zakarpattia region were planted for it.
The trade language here is older and more settled than in the frozen categories, largely because size grading by count has been standardised for decades. UNECE Standard DDP-07 gives the vocabulary: size expressed as a count per unit weight, moisture classes, and defect tolerances. It is a trade convention rather than Union law, and it binds a contract only where the contract names it, but almost every serious contract does.
Grades, cuts and calibration
Size count. The primary grade. Prunes are sold as a count per kilogram or per 500 grams, in bands, with a lower count meaning larger fruit and a higher price. The count is verified by weighing out a sample and counting it, which sounds trivial and is where most disputes are actually resolved. Specify the band, the sample size and the tolerance.
Pitted or unpitted. Pitted fruit is the industrial and retail default. Pitting costs weight and introduces the pit fragment question, which is managed by X-ray. Unpitted fruit is a smaller trade and is priced on the same count ladder, which means a like-for-like comparison between a pitted and an unpitted offer needs the pit weight taken out first.
Moisture class. Higher moisture gives a softer, plumper fruit that eats better and weighs more; lower moisture gives a longer, safer shelf life. The two are traded as different classes. Water activity is the parameter that actually predicts mould growth, and moisture is the parameter that gets specified, so a careful contract carries both.
Preservative. Higher moisture classes are commonly stabilised with potassium sorbate, which is a permitted additive on defined dried fruit categories and must be declared. Unpreserved high-moisture fruit exists and needs a shorter shelf life, tighter water activity control or a pasteurisation step. This is a specification decision with a label consequence, and it should be made before the first order rather than discovered on a certificate.
Defects. Fermented or mouldy fruit, insect damage, scarring, attached stems and pit fragments in pitted fruit each carry a separate tolerance. Sugaring, the white crystalline bloom that appears on stored fruit, is not spoilage but will be treated as one by a retail buyer who has not seen it before.
Seasonality and availability
Plum harvest runs from late August through early October, and drying capacity is the constraint rather than fruit availability. A tunnel or belt dryer takes a fixed throughput and the crop arrives faster than that, so part of the crop goes to the frozen line and part goes to juice and puree.
That allocation is worth understanding as a buyer. The largest, soundest fruit goes to drying because it carries the count premium. Fruit that is small, slightly over-ripe or blemished goes to the frozen and puree lines. This is not a quality failure on the frozen side; it is a rational use of the crop, and it explains why frozen plum is a lower-value line than the dried one from the same orchard.
Dried stock is supplied all year from conditioned store. Sugaring increases with storage time and with temperature cycling, so a lot bought in June from the previous October’s production will look different from a lot bought in November, at the same specification.
What the buyer checks at intake
- Identity and lot: crop year, production date, size count band, pitted status, moisture class, preservative status and the establishment approval number.
- Weighed size count on a sample of the contracted size, drawn from several cartons. This is the check that settles the specification and it takes ten minutes.
- Moisture and water activity together, because they answer different questions and a lot can pass one and fail the other.
- Pit fragment check on pitted fruit, on a weighed sample, with the supplier’s X-ray rejection records for the production date.
- Texture and appearance against the sealed reference: pliability, skin condition, absence of case-hardening, and the degree of sugaring.
- Preservative result where potassium sorbate is used, checked against the label copy the buyer intends to print.
- Certificate of analysis for residues, heavy metals, mycotoxins where the buyer specifies them, and the microbiological panel including yeasts and moulds.
Where it is used
Retail snack is the largest outlet and it is entirely count-driven. The large counts sell as a premium pack, the middle counts as everyday retail, and the small counts go industrial.
Bakery takes diced and whole prune into fruit breads, energy bars and filled products, where the high sugar and the pectin behaviour matter and the count does not. Diced prune is often coated with a small amount of rice or oat flour to stop it agglomerating, which is an ingredient and has to be declared.
Confectionery takes whole pitted fruit for chocolate-coated and stuffed products, where piece uniformity is worth more than size.
Nutraceutical and functional food buyers take prune and prune juice concentrate for the sorbitol and fibre content. Any specific health claim made on that basis has to be an authorised claim, which is a labelling question rather than a sourcing one and is covered in the grading and import guide.
Standards and routes
Dried plum is an ambient good with one real transport risk: moisture. A high-moisture class fruit in a carton without an effective barrier liner will equilibrate with a humid trailer and arrive above specification, and the mould that follows appears in the buyer’s store rather than the supplier’s.
Heat is the second risk. Sustained transit above roughly 25 degrees Celsius accelerates sugaring and darkens the fruit. A summer road leg across southern Europe is worth planning, and a temperature-controlled trailer is a legitimate specification for a high-value large-count consignment.
The main corridors run through Poland and Czechia into the Central European processing cluster. Documentation follows the standard third-country set, with the phytosanitary position confirmed for the commodity as traded. Assurance is normally BRCGS or IFS Food, and organic lots additionally carry the organic control body certificate.
