Grading is the most misunderstood part of a fruit contract. Buyers new to the category often assume there is a single official grade that a lot either meets or fails, and that a certificate proves it. In practice three separate systems operate at once, they answer different questions, and only one of them is enforceable against your supplier.
The three systems and what each one governs
The first system is the EU marketing standards framework. Commission Implementing Regulation (EU) No 543/2011 lays down specific marketing standards for a defined list of fresh fruit and vegetables and a general marketing standard for the rest. It is where the familiar Extra, Class I and Class II designations come from, along with the rules on sizing, uniformity and labelling of the produce unit.
The critical limitation, and the one that trips up processing buyers, is scope. The marketing standards apply to produce supplied fresh to the consumer. Produce intended for industrial processing is generally outside them, subject to the identification requirements set out in the regulation. If you are buying apples to dice and freeze, the Class I framework is not your specification and citing it in a contract will not give you what you think it does.
The second system is food law proper: residues under Regulation (EC) No 396/2005, contaminants under Commission Regulation (EU) 2023/915, microbiological criteria under Regulation (EC) No 2073/2005, labelling under Regulation (EU) No 1169/2011, and official controls under Regulation (EU) 2017/625. This system is not about grade at all. It sets the floor below which a consignment is not lawful, and it is enforced by the competent authority rather than by your supplier’s quality manager.
The third system is the contract specification, and this is the one that actually determines what arrives on your pallet. It is private, it is bilateral, and it can be as tight or as loose as the two parties agree. Everything a processing buyer really cares about – defect tolerances, size distribution, drip loss, Brix, foreign matter, pack format – lives here.
The practical hierarchy is simple. Food law sets the floor, the marketing standards govern the fresh consumer trade, and the contract specification governs your delivery. A supplier can be fully compliant with the first two and still deliver a lot you cannot use.
Why processing grade is a different discipline
Fresh grading is largely about appearance: shape, colour, uniformity, freedom from visible blemish. Processing grade is about what survives the process. The two diverge sharply.
A misshapen apple is a Class II defect in the fresh trade and completely irrelevant once it has been diced. Conversely, internal browning, a low dry matter or a soft flesh texture are invisible in a fresh grading hall and are the three things most likely to ruin a frozen dice line. This is why a processing specification is built from measurable properties – firmness, dry matter, soluble solids, defect counts by category – rather than from a class letter.
The single most useful exercise a new buyer can do is to write down, for their own process, which fruit properties change the yield and which change the finished product, and then make sure both lists appear in the specification with a method attached. Anything not on those lists is negotiable. Anything on them is not.
Building a defect table that works
A defect table is the operational heart of a fruit specification, and most of them are written badly. The common failure is a single combined tolerance: no more than five per cent defects. That number is unenforceable because it does not tell the supplier which defect to spend money removing.
A workable table separates defects into classes that map onto removal equipment.
| Defect class | Typical examples | Removed by |
|---|---|---|
| Foreign matter | Stone, glass, metal, plastic | Destoner, metal detector, X-ray |
| Extraneous vegetable matter | Stalk, leaf, calyx, stone fragments | Aspiration, optical sort, manual belt |
| Colour defects | Under-ripe, over-ripe, oxidised | Colour sorter |
| Structural defects | Split, crushed, fines, undersize | Sieve separation, size grading |
| Internal defects | Core browning, cavity, internal rot | Intake sampling only |
The last row is the one that matters most and the one most often omitted. Internal defects cannot be sorted out downstream. They are controlled by raw material selection and by intake sampling, which means the tolerance has to be set against a sampling plan, not against a sorting capability.
What is actually checked at the border
Official controls under Regulation (EU) 2017/625 are risk based. For most frozen and processed fruit from Ukraine entering the EU, the routine checks are documentary and identity checks, with physical checks and sampling applied according to the risk profile for the commodity and origin. Certain commodity and origin combinations carry an increased frequency of controls set out in the temporary-increase regulation, which is amended periodically; a buyer should check the version in force rather than rely on last year’s position.
What is not checked at the border is your grade. No official inspector will measure your dice size distribution or your drip loss. If those matter, they are verified on arrival at your own intake, against your own specification, and the commercial remedy is in your contract, not in food law. This is why the import process guide treats intake inspection as a separate discipline from customs clearance.
Where organic and other schemes sit
Organic status under Regulation (EU) 2018/848 is a production and control claim, not a grade. Organic fruit is graded exactly the same way as conventional fruit and an organic certificate says nothing about defect levels. The two are often conflated in enquiries, with buyers assuming organic implies a higher physical quality. It does not, and on some crops the visible defect rate is higher.
Private food safety schemes – BRCGS, IFS Food, FSSC 22000 – certify the management system at the processing site. They tell you the supplier has documented control, traceability and a functioning HACCP plan. They do not certify any individual consignment and they are not a substitute for a specification.
A certified supplier with a vague specification will reliably deliver a lot that is safe, traceable and wrong for your process. Certification and specification solve different problems.
A practical sequence for a new origin
- Define your process-critical properties and attach a test method to each one.
- Write the defect table by removal class, with internal defects sampled at intake.
- Agree the sampling plan and the retention sample protocol before the first order.
- Verify the food safety certificate scope covers the actual processing site and the actual product category, not a related one.
- Run a paid trial pallet through your own line and grade it yourself before committing programme volume.
- Only then negotiate tolerances, because you now know which ones cost the supplier money and which are free.
That sequence takes a season. Skipping it costs more. The most expensive fruit in the market is a cheap lot that has to be reworked or rejected after it has already been paid for and shipped in a reefer.
