Extra virgin, virgin, lampante: the IOC/EU categories
ArticleIn brief. Olive oil is classified into commercial categories by the IOC/T.15/NC standard and EU regulation. The three key virgin categories: extra virgin (EVOO) — acidity ≤ 0.8%, no defect (Md = 0); virgin — acidity ≤ 2.0%, Md ≤ 3.5; lampante — acidity > 2.0% or Md > 3.5, not marketable as is in the EU (it goes to refining). Added to these are refined oil, olive oil (blend) and pomace oil. Classification rests on chemistry and the sensory panel, each parameter having to meet its threshold.
Extra virgin, virgin, lampante, refined, pomace: these categories are not marketing arguments, they are regulatory classes with precise thresholds. Knowing what distinguishes each means avoiding paying an extra virgin price for a downgraded oil. Here is the complete grid, for the B2B buyer.
What is olive oil classification based on?
An olive oil is classified according to several parameters simultaneously, defined by the commercial standard of the International Olive Council (IOC/T.15/NC) and European Union regulation:
- Free acidity (% oleic acid) — degradation of the fruit.
- Peroxide value (mEq O₂/kg) — primary oxidation, freshness.
- UV absorbances: K232, K270, ΔK — oxidation and traces of refining.
- IOC sensory panel: median of defects (Md) and of fruitiness (Mf).
A single parameter out of range downgrades the oil to the lower category. An oil is extra virgin only if all its parameters meet the EVOO limits at once.
The threshold table by category (IOC/EU)
Here are the thresholds per category set by the IOC standard and EU regulation. Reference data, to be verified against the texts in force.
| Category | Max free acidity | Max peroxide | Md (defects) | Mf (fruitiness) | Marketable as is |
|---|---|---|---|---|---|
| Extra virgin (EVOO) | ≤ 0.80% | ≤ 20 | = 0 | > 0 | Yes — premium category |
| Virgin | ≤ 2.0% | ≤ 20 | ≤ 3.5 | > 0 | Yes |
| Ordinary virgin (IOC only) | ≤ 3.3% | ≤ 20 | ≤ 6.0 | — | IOC yes, EU no |
| Lampante | > 2.0% (EU) | — | > 3.5 | may = 0 | No → refining |
| Refined | ≤ 0.3% | — | — | — | After industrial refining |
| Pomace | — | — | — | — | After industrial refining |
Peroxide expressed in mEq O₂/kg. Refined, olive and pomace oils require an industrial process and are never "virgin" oils.
Extra virgin, virgin, lampante: the difference made clear
Extra virgin (EVOO)
The premium category. Acidity ≤ 0.8%, peroxide ≤ 20, compliant UV indices (K232 ≤ 2.50, K270 ≤ 0.22, ΔK ≤ 0.01) and above all no sensory defect (Md = 0) with perceptible fruitiness (Mf > 0). It is the only one that combines flawless chemistry with an intact taste profile.
Virgin
A sound but less perfect oil. Acidity tolerated up to 2.0% and slight sensory defects accepted (Md ≤ 3.5). It remains edible and directly marketable, but cannot be sold as "extra virgin".
Lampante
A defective virgin oil: acidity > 2.0% (EU) or median of defects > 3.5. Its name comes from its historical use in oil lamps. It is not marketable as is in the EU and must go through refining before any placing on the market.
What changes on EU export
The European Union does not recognize the IOC "ordinary virgin" category. In practice: beyond 2.0% acidity (or Md > 3.5), a virgin oil is directly classified lampante on the EU side, where the IOC would still classify it "ordinary".
For an import into Europe, it is therefore the EU category that is authoritative. A serious exporter provides a COA that rules on the EU category of the lot, not only on the IOC category. Never confuse the two frameworks when contracting.
How to use categories when buying in bulk
- Set the category before the price. First determine the real class of the lot via the COA, then negotiate the price for a given category. A low price on a downgraded oil is not a good deal.
- Require chemistry + panel. An oil is officially extra virgin only if both chemistry and panel comply. A COA without a panel is incomplete.
- Beware of "borderline" oils. An acidity at 0.79% or a peroxide at 19 passes EVOO on paper but leaves little margin for drift during transport.
- Check the framework. Make sure the announced category is indeed the EU category if you import into Europe.
To automatically classify a lot from its figures, enter them in our COA quality classifier: it tells you the official category. The Tunisian oils Chemlali (South/Sfax) and Chetoui (North), cold-extracted, commonly reach the extra virgin thresholds.
FAQ — IOC/EU olive oil categories
What is the difference between extra virgin, virgin and lampante?
Extra virgin has acidity ≤ 0.8% and no defect (Md = 0). Virgin tolerates up to 2.0% acidity and slight defects (Md ≤ 3.5). Beyond 2.0% or Md > 3.5 (EU), the oil is lampante: not edible as is, it goes to refining.
What is extra virgin olive oil?
It is the premium category. It must combine: acidity ≤ 0.8%, peroxide ≤ 20 mEq O₂/kg, compliant UV indices (K232 ≤ 2.50, K270 ≤ 0.22, ΔK ≤ 0.01) and a defect-free sensory panel (Md = 0) with perceptible fruitiness (Mf > 0). All parameters must be met at once.
What are lampante oil and pomace oil?
Lampante oil is a defective virgin oil (acidity > 2.0% or Md > 3.5), not marketable as is: it must be refined. Pomace oil is extracted from the pressing residue (pomace) by solvent, then refined. Neither can be sold as virgin oil.
How many olive oil categories are there?
There are three virgin oils (extra virgin, virgin, lampante — plus "ordinary" under the IOC), refined oil, olive oil (blend of refined and virgin) and olive pomace oil. Only extra virgin and virgin can be sold directly to the consumer.
Is the IOC category the same as the EU category?
No. The EU does not recognize the IOC "ordinary virgin" category. Beyond 2.0% acidity (EU), a virgin oil is classified lampante, whereas the IOC would classify it "ordinary". For an import into Europe, it is the EU category that is authoritative.
How do you know which category an oil falls into?
By reading its COA (certificate of analysis) from an IOC-accredited laboratory: it indicates acidity, peroxide, UV indices and the panel. Each parameter must meet the threshold of the target category. A single figure out of range downgrades the oil.
