PDO vs PGI vs Organic (BIO), Explained for Buyers

Three letters can add or destroy value on a shelf. This guide explains what PDO, PGI and Organic (BIO) legally mean under EU regulation, how a producer earns each mark, what documentation you should always request, and how the three interact with private-label projects.

The three schemes in one line each

  • PDO (Protected Designation of Origin): every production step, from raw material to finished product, happens in the defined geographic area, using traditional know-how.
  • PGI (Protected Geographical Indication): at least one step of production happens in the defined area; the link to origin is real but less strict than PDO.
  • Organic (BIO): a farming and processing standard, unrelated to geography; certified against EU Regulation 2018/848.

PDO in practice

For Greek food buyers, PDO is the strongest guarantee of authenticity. Feta PDO must be produced in mainland Greece and Lesvos, from at least 70% sheep's milk with the balance from goat, using traditional methods. Kalamata olive oil PDO must come from a defined zone in Messenia. If a supplier offers you "PDO feta produced in Bulgaria," it is not PDO feta, and cannot legally be sold as such in the EU.

Documentation to request: the producer's PDO certification, the batch code linking your shipment to a certified production run, and the control-body reference.

PGI in practice

PGI is a real quality mark, but the legal bar is lower. For PGI Crete olive oil, the olives must be grown and milled on Crete but bottling may happen elsewhere within defined rules. For buyers this usually means: strong geographic story, slightly more flexibility, generally lower price than PDO.

Organic (BIO) in practice

Organic is a process certification. The producer's fields, mill or dairy, packaging site and supply chain are audited annually by an accredited control body. In the EU, the finished pack must carry the green Euro-leaf logo and the code of the control body (for example EL-BIO-01 for a Greek producer).

Organic and PDO are compatible. Organic PDO Kalamata olive oil or organic PDO feta are both legitimate and commercially attractive positions.

Private-label implications

Under private label the certification belongs to the producer, not to the brand. You may use the PDO / PGI / BIO name and logo on your artwork provided:

  • The producer holds a live certification for the specific SKU you are packing.
  • The final artwork is approved by the producer and, for organic, by the control body.
  • Every finished pack carries the required legal information (control-body code, batch, product designation).
  • You keep on file the certificates covering every production run of your programme.

Common misconceptions

  • "Greek-style feta" is not feta. Feta is a legally protected name in the EU.
  • "Kalamata-type olives" grown outside the Kalamata PDO zone may be sold as "Kalamon" but not as "Kalamata PDO."
  • PGI does not mean lower quality; it means a different, still-enforceable link to origin.
  • Organic is not a taste or nutrition claim; it is a process claim.
