Industrial & pharma EDI — Nestlé, Novartis, Roche, ABB, Lonza, Sika

Switzerland hosts world champions in food, pharma and industry. All have exchanged in EDI with their suppliers and distributors for decades. For the newcomer: behind a Roche medicine box or a Nestlé bar, an EDIFACT flow has already carried the order, the dispatch advice and the invoice — often enriched, in pharma, with unique serial numbers for traceability.

History — multinationals as EDI pioneers

Nestlé (Vevey), Novartis and Roche (Basel) are among the world's earliest adopters of EDIFACT EDI, from the 1990s. ABB (Zurich/Baden) and Sika (Baar) generalised EDI and OFTP2 over the ENX industrial network. Lonza (Basel/Visp), a pharma contract-manufacturing (CDMO) giant, structures its entire chain in EDI.

Pharma added a layer: serialisation — each box carries a unique serial number as a data matrix, to fight counterfeiting and enable targeted recalls. In Switzerland, the regime falls under Swissmedic, distinct from the EU system (FMD/EMVS) but aligned with the same spirit.

1990s      | Nestlé, Novartis (formed from the 1996 Ciba-Geigy + Sandoz
           | merger) and Roche roll out EDIFACT EDI with their global
           | suppliers and distributors.
           |
2000-2010  | ABB and Sika generalise EDI / OFTP2 over the ENX industrial
           | network; Lonza structures its pharma CDMO chain in EDI.

2011-2019  | GS1 Healthcare standardises pharma identification (GTIN, GLN,
           | SSCC) and item-level serialisation (unique serial numbers).

2019-2024  | Pharma serialisation: deployment of unique serial numbers and
           | data matrix on boxes, under the Swissmedic regime (aligned with
           | the spirit of the EU FMD without falling under it).

Governance — GS1, Swissmedic, ENX

Three authorities frame this landscape: GS1 Switzerland Healthcare (pharma identification and serialisation standards), Swissmedic (Swiss Agency for Therapeutic Products — authorisation and supervision), and the ENX Association (a secure cross-industry network for OFTP2 flows, mainly in automotive and heavy industry).

Schema — EDIFACT, pharma serialisation

The dispatch advice (DESADV) is central in industry: it carries the packaging hierarchy (SSCC), the product GTIN, the batch number and the expiry date — critical data for pharma traceability:

Pharma vs heavy industry vs retail

Adoption — verticals and transport

• Food: Nestlé drives global EDI flows, with a GS1 data pool for product quality.
• Pharma: Novartis, Roche and Lonza combine B2B EDIFACT with Swissmedic item serialisation.
• Heavy industry: ABB and Sika rely on OFTP2/ENX, inherited from automotive and electrotechnical chains.
• Cross-border: for the EU, EDIFACT flows coexist with structured e-invoicing (PEPPOL, Factur-X, FatturaPA) depending on the customer country.

Common pitfalls

• Forgetting batch and expiry. In pharma/food, a DESADV without batch number or expiry date is unusable for traceability.
• Confusing serialisation and EDI. Item serialisation is a registry distinct from the EDI logistics flow; the two must be consistent.
• Wrong transport network. OFTP2 over ENX (industry) ≠ AS2/VAN (retail/pharma); the wrong channel blocks the exchange.
• Ignoring the Swissmedic / EU gap. A Swiss exporter to the EU must handle both the Swissmedic regime and the destination market's FMD/EMVS requirements.
