Industrial EDI — HELLENiQ, Motor Oil, TITAN, Metlen

Beyond retail, Greek heavy industry has exchanged its commercial documents by EDI for a long time. The players are the champions of the economy: HELLENiQ ENERGY (ex-Hellenic Petroleum) and Motor Oil Hellas in refining, TITAN Cement in cement, Metlen (ex-Mytilineos) in aluminium and energy, Coca-Cola HBC in beverages, Viohalco in metals. Typical protocols: EDIFACT (orders, invoices) over OFTP2 / AS2. Since 2021, all also report to myDATA.

History — heavy industry and EDI

The big Greek industrial groups adopted ERPs (SAP, Oracle) and EDI exchanges early, pushed by their international customers and suppliers. Refining (Hellenic Petroleum, Motor Oil) and cement (TITAN) have demanding supply chains — fuels, clinker, raw materials — that justify automating orders and invoices. The recent rebrandings — Hellenic Petroleum → HELLENiQ ENERGY, Mytilineos → Metlen Energy & Metals — did not change the underlying EDI flows.

2000s       | The big Greek groups (refining, cement, metallurgy) deploy ERPs
            | (SAP, Oracle) and B2B EDI exchanges with international industrial
            | suppliers and customers.
            |
2010s       | Energy: Hellenic Petroleum and Motor Oil structure their logistics
            | flows (fuel orders, delivery notes, invoices). Cement: TITAN exports
            | and standardises its exchanges. EDIFACT + OFTP2 dominant.
            |
2017-2021   | Mytilineos consolidates energy + metals (Aluminium of Greece).
            | Coca-Cola HBC (Swiss-listed, Greek roots) runs large-scale
            | retail/industrial EDI. Viohalco (metals) in Belgium.
            |
2020-2021   | myDATA: all these entities must transmit their invoices to AADE.
            | The industrial EDI flows are doubled by a tax report.
            |
2022-2024   | Hellenic Petroleum becomes HELLENiQ ENERGY; Mytilineos becomes
            | Metlen Energy & Metals. Rebranding + listing, but continuity of
            | the underlying EDI flows.
            |
2025-2026   | B2B mandate: structured industrial invoices via accredited providers
            | are added to the existing logistics EDI.

Governance — standards and operators

Unlike retail (framed by GS1 Hellas), industrial EDI is less centralised: each large account imposes its specifications on its partner ecosystem. The reference standards remain the EDIFACT messages (UN/CEFACT) for content, and the OFTP2 protocols (Odette, inherited from automotive) or AS2 for secure transport. International EDI operators / VANs connect these groups to their European counterparts. Since 2021, the common layer imposed by the state is myDATA.

Schema — verticals and protocols

Each sector has its specifics, but the EDIFACT + OFTP2/AS2 + myDATA reporting base is shared. Overview:

Greek industrial verticals and typical protocols
================================================
Energy / refining
  HELLENiQ ENERGY (ex-Hellenic Petroleum) — Aspropyrgos, Elefsina,
    Thessaloniki refineries; fuel, logistics, B2B flows.
  Motor Oil Hellas — Corinth refinery; export + distribution.
    -> EDIFACT (ORDERS/DESADV/INVOIC) + OFTP2/AS2

Construction materials
  TITAN Cement — cement, multinational (USA, Balkans, Egypt).
    -> EDIFACT export + supplier portals

Energy & metals
  Metlen (ex-Mytilineos) — aluminium (Aluminium of Greece), energy,
    EPC. Heavy industrial flows, long-term contracts.
    -> EDIFACT + OFTP2 over secure networks

Beverages
  Coca-Cola HBC — bottler (listed on SIX Switzerland, Greek roots),
    very high-volume retail + industrial EDI.
    -> EANCOM + EDIFACT, distribution-centre integration

Metallurgy
  Viohalco — copper, aluminium, steel, cables (Belgian holding,
    Greek origin). Intra-EU export flows.
    -> EDIFACT + OFTP2

Common layer (since 2021)
  All these entities: myDATA reporting (AFM, MARK) on their invoices.

Industrial EDI vs retail vs myDATA

Adoption — the big Greek accounts

• HELLENiQ ENERGY — Aspropyrgos, Elefsina, Thessaloniki refineries; intensive fuel and logistics B2B flows.
• Motor Oil Hellas — Corinth refinery, strong export and distribution component.
• TITAN Cement and Metlen — materials and metals, long-term contracts, EDIFACT export exchanges.
• Coca-Cola HBC and Viohalco — high volumes, international standards, Greek entities under myDATA.

Common pitfalls

• Believing industrial EDI exempts you from myDATA. OFTP2/AS2 flows between partners do not replace tax transmission to AADE.
• Heterogeneous EDIFACT profiles. Each large account has its own segments and versions; a generic connector often fails — wire to the partner's profile.
• VAT prefix GR instead of EL. Same trap as everywhere in Greece: the VAT is EL + AFM.
• Confusing legal name and invoicing entity. Multinational groups have several entities; the Greek invoice must carry the AFM of the relevant Greek entity.
• Neglecting evidential archiving. Long-term industrial flows require compliant archiving; the myDATA proof (MARK) must be retained.
