Exporting Georgian hazelnuts by container: moisture control, aflatoxin risk and the EU's check rate
Georgian hazelnut exports run to roughly 15,000 tons and $90 million a year, mostly as shelled kernel rather than in-shell, and mostly bound for the EU - and almost everything about shipping that cargo safely comes down to a single number that has nothing to do with the container itself: moisture content. Get that wrong and the packaging format, the route and the paperwork stop mattering.
Four packaging formats, and which buyer each one fits
| Format | How it works | When it fits |
|---|---|---|
| Woven polypropylene sacks (5-25kg) | the standard retail and food-service format, easy to count and inspect | the default for most kernel shipments, no special equipment needed to handle |
| Jute bags (50-80kg) | the traditional bulk format, breathable but less protective than a sealed sack | for buyers set up to handle a coarser, larger unit |
| Vacuum-sealed cartons | kernels packed with oxygen reduced before sealing, inside a carton | for long-distance or long-transit routes, where rancidity risk from oxygen exposure builds up over weeks |
| Bulk bags (500-1,000kg FIBC) | large woven bags for high-volume shipments to a processor | for buyers who process straight from bulk rather than needing retail-ready units |
None of these four formats is simply a matter of what's cheapest - the right one follows from who's buying and how far the cargo is travelling, and getting it wrong doesn't just waste money, it changes how exposed the kernel is to the one risk that actually spoils a shipment.
Why moisture content decides almost everything else
Hazelnut kernels have to stay at or below 6% moisture by the international standard that governs them, and that number isn't arbitrary: the mould that produces aflatoxin needs both warmth and moisture well above that level to establish itself, so a kernel shipment that starts dry and stays dry never gives it the conditions it needs.
A shipment that starts dry doesn't automatically stay dry for the whole journey - moisture control is a start-of-trip decision that has to survive weeks of temperature change between a Georgian warehouse and a buyer's dock, not a box that gets checked once and forgotten.
What condensation does to a shipment that started perfectly dry
A sealed container crossing climate zones can generate its own moisture from the inside: warm, humid air trapped at loading condenses on cooler container walls later in the route, a phenomenon shippers call "container rain" - and it doesn't need the whole cargo to be wet to cause a problem, just a pocket of local humidity high enough, for long enough, near the aflatoxin threshold.
Samegrelo and Guria: where the crop comes from, and who's buying it
That's why the packaging and the container prep matter as much as the moisture reading taken before the door closes: a liner and desiccant aren't decoration, they're what keeps a shipment that tested fine at 5.5% moisture from finding trouble at 14% relative humidity somewhere over a multi-week route.
The years the stink bug changed the industry, and what actually recovered
Nearly all of Georgia's hazelnut cultivation sits in the west of the country, with Samegrelo the largest single growing region and Guria second - roughly 75,000 hectares and 70,000 farming households feed nine drying and storage facilities and around 60 processing plants, and the industry's modern shape owes a lot to one investment: Ferrero's Georgian subsidiary, established near Zugdidi in 2007, which was also the lead actor behind founding the Georgian Hazelnut Growers Association that same year.
Ferrero remains a structural buyer rather than a spot one - it lists Georgia among its global hazelnut sourcing countries and has run long-term development partnerships in the sector - and alongside it, Italy, Spain, Germany, France, Poland, the Czech Republic and the UK are the markets Georgian kernel most often ends up in, generally through processors rather than direct retail.
What we check before a hazelnut container is sealed
| Check | What it confirms | Why it matters |
|---|---|---|
| Moisture content at or below 6% | kernels tested against the UNECE standard for hazelnut kernels before loading, not assumed from the harvest season | above this range, aflatoxin-producing mould has the conditions it needs, and that's a rejected shipment, not a quality complaint |
| Container liner and desiccant against condensation | a dry cargo checked against the temperature swing it will face crossing climates, not just against how it left the warehouse | "container rain" from condensation can push local moisture into aflatoxin territory even when the average of the load tests fine |
| Wood pallets carrying an ISPM 15 mark | the heat-treatment or fumigation stamp on the pallets themselves checked before loading, not assumed present | this is a general global requirement for the wood, not specific to hazelnuts, but it stops a shipment at the border just as fast |
| Aflatoxin test report matched to the destination | a current lab report ready for a shipment headed to the EU specifically, not a generic certificate | EU customs runs a 30% official-controls check rate on Georgian hazelnuts, and a shipment held for testing without paperwork in hand costs real time |
The brown marmorated stink bug arrived in Georgia in 2015 and did real, measurable damage to the crop for years afterward - average annual yield fell from around 31,600 tons before the pest arrived to roughly 25,400 tons a year through 2019, bottoming at about 17,000 tons in 2018, with cumulative export losses estimated in the hundreds of millions of lari - and while the sector has since recovered export volume, that recent history is a reminder that Georgian hazelnut supply has had real, weather-and-pest-driven swings, not just steady annual growth.
What goes wrong without a controlled process
Most of what actually goes wrong with a hazelnut shipment isn't a dramatic failure at the port - it's a handful of specific gaps tied to how sensitive this cargo is to moisture and time, each easy to miss on paper even when the load looks fine on loading day:
- Moisture tested once at harvest, not again before loading — weeks in storage change conditions a harvest-time reading can't predict
- No container liner on a route crossing hot and cool climates — the load tests dry at origin and still develops a condensation problem mid-route
- Wood pallets loaded without checking the ISPM 15 stamp — a border stops the shipment over the pallets, not the cargo itself
- EU-bound shipment sent without a current aflatoxin test report — the 30% check rate catches it anyway, but now without paperwork in hand to speed the hold
- Packaging format chosen by cost alone — a long-transit route sent in ordinary sacks instead of vacuum-sealed cartons, with rancidity risk building the whole way
- Supply volume assumed stable year to year — without accounting for how much a pest year or a weak harvest can move available tonnage
None of this needs specialist lab equipment on-site to catch - it needs someone treating moisture and packaging as the actual product-safety question they are, rather than a formality to get through before the container closes.
What the EU's import checks actually look for
For hazelnuts headed to the EU specifically, the destination's own import-control regime is worth planning around directly: Georgian hazelnuts currently sit on the EU's list for a 30% official-controls check rate tied to aflatoxin risk, meaning close to a third of shipments face a border hold for testing - not a stink-bug-specific measure, an aflatoxin one, and a shipment that arrives with its own current lab report in hand clears that hold far faster than one that doesn't.
Development prospects
Export volumes and values have both grown meaningfully in recent reporting periods, and the industry's shift toward exporting shelled kernel rather than in-shell nuts - kernel now makes up close to 90% of export volume - points toward a sector adding more value before the product ever reaches a container, which raises the stakes on getting the moisture and packaging right rather than lowering them.
In short
Getting Georgian hazelnuts into a container safely starts with a number, not a format: moisture at or below 6%, verified before loading and protected against condensation for the whole route, with the packaging and pallet documentation to match. Tell us the format, the destination and whether it's kernel or in-shell, and we'll set out exactly how it should be packed, prepped and shipped.
