In hazelnuts and pistachios the first question a European buyer asks is not about price, calibre or flavour. It is whether the aflatoxin analysis exists, what it shows, and whether it was measured against the right limit. The category is unusual in that respect, and the reason is structural: the contaminant is real, the limits are tight, and the border checks are frequent enough that a lot without the right paperwork is a lot that may not arrive.
The limits depend on what happens next
Regulation (EU) 2023/915 sets two tiers for each nut, according to whether the lot will be sorted or physically treated before it reaches a consumer.
For hazelnuts placed on the market for direct consumption or as a food ingredient, the maximum is 5 µg/kg aflatoxin B1 and 10 µg/kg total aflatoxins. For hazelnuts that will be sorted or treated first, the limits are 8 µg/kg B1 and 15 µg/kg total.
For pistachios the values differ: 8 µg/kg B1 and 10 µg/kg total for direct consumption or ingredient use, and 12 µg/kg B1 and 15 µg/kg total for lots that will be sorted or treated first.
The two-tier structure exists because sorting genuinely removes contaminated nuts. It also creates the most common compliance failure in the category, which is a mismatch between the use a lot was declared for and the use it was put to.
The declared use has to match the actual use
A supplier can lawfully sell a lot at the higher limit if it is declared for sorting. A buyer who receives that lot and uses it directly — packs it, mills it, adds it to a product — without sorting has placed a non-compliant food on the market, even though every document in the chain was accurate.
The alignment between declared use and actual use is therefore a specification point. A buyer who does not sort should specify direct-consumption limits and confirm the certificate was assessed against them. A buyer who does sort can accept the higher tier, but has to actually do the sorting.
What changed for Turkish pistachios
Commission Implementing Regulation (EU) 2026/194, applying from 18 February 2026, raised the frequency of identity and physical checks on pistachios, mixtures and products produced from pistachios originating in Türkiye to 50%. The stated reason was a high rate of non-compliance for aflatoxin contamination found in official controls.
Fifty per cent means half of consignments are selected for sampling and laboratory analysis at the EU border. That is a sampling rate rather than a rejection rate, but it changes the planning calculus completely: a supply chain built on the assumption that most consignments clear quickly is now wrong half the time. Clearance time has to be planned for the slower case.
Why the certificate has to exist before loading
Aflatoxin contamination is characteristically uneven. A lot is not uniformly contaminated; it contains a small number of heavily affected nuts distributed unpredictably through it. Detecting that requires a sampling plan designed for heterogeneity — enough increments from enough points, properly combined — and a laboratory result, and both take time.
Done before shipment, that is a schedulable step in the production window. Done after the container is packed, it is a delay. And a failure discovered before loading is a rejected lot; a failure discovered at the border is a rejected consignment, in bond, with freight already paid. The economics are not close.
Where we sit
TeraVella works in nuts as a sourcing partner — we do not claim to own an orchard, a cracking plant or a roasting line. What we do is fix the intended use and the applicable limits in the written specification, plan representative sampling and analysis into the production window rather than after it, collect the certificate before the goods move, and manage documented delivery in bulk, vacuum or retail packs under your own brand. Where a requested timeline no longer allows for representative sampling, we say so rather than ship and hope. We hold ISO 9001, ISO 22000 and ISO 27001 and make no organic or other certification claim. Volumes and prices are confirmed at quotation.
