Spain's Paper Transport Document Just Disappeared: What the DeCA Deadline Means for Domestic Runs and Cabotage

From 5 October 2026, Spain requires every domestic road freight shipment, including cabotage, to carry a digitally native control document called the DeCA. Here is what actually changed, who it hits, and how to stay off the roadside fine list.

A document Spain has required for years just changed format, not substance

Spain has required a control document for domestic road freight since 2012, under Orden FOM/2861/2012. Nothing about that obligation disappeared this autumn. What changed is the format: from 5 October 2026, that document must exist as a digitally native file called the DeCA, the Documento electrónico de Control Administrativo, and paper is no longer a valid substitute. As one industry summary put it, this requirement "está regulado en la Orden FOM/2861/2012, de 13 de diciembre" and simply moves to electronic form.

The legal basis is Spain's Ley 9/2025 de Movilidad Sostenible, which entered into force on 5 December 2025 and gave the sector a ten month transition window. The technical detail arrived later: a Resolution dated 5 June 2026 from the Dirección General de Transporte por Carretera y Ferrocarril, published in the BOE on 12 June, which sets out exactly what the digital document must look like and how it must be handled.

What the DeCA actually requires

The technical bar is specific and not optional. The document must be generated before the service starts, delivered as a PDF of no more than 5 MB, and it has to be "nativa digital", meaning a company cannot simply scan a paper form and call it compliant. It must carry an embedded QR code linking to a unique URL over HTTPS, downloadable on request during a roadside inspection, and records have to be kept for at least one year.

Crucially, the content itself has not changed. The data fields required are still the ones set out in Article 6 of Orden FOM/2861/2012: goods details, origin and destination, shipper and carrier identity, vehicle and service conditions. What changes is how that data gets generated, handed over, made available at the roadside and archived, not what gets collected.

Who is actually caught by this, and who is not

The obligation applies to public road freight transport with both origin and destination inside Spain, and it explicitly includes cabotage operations carried out in Spanish territory, regardless of where the carrier is established. International transport that only passes partly through Spain stays outside the DeCA regime and continues to rely on the control documents set out in the relevant international conventions, typically the CMR consignment note.

That carve-out excludes more than through-traffic. Guidance circulating among Spanish transport lawyers also lists private own-account transport, removals, parcel delivery and the recovery of accident-damaged vehicles as outside the DeCA's scope. For everyone else running loads that start and end inside Spain, paper is finished as of 5 October.

Why this matters for fleets based outside Spain

The cabotage inclusion is the part non-Spanish operators tend to miss. A foreign-registered truck that delivers an international load into Spain and then picks up a second, purely domestic leg, for example loading in Zaragoza for delivery to Seville, is doing cabotage and from 5 October that second leg needs a DeCA. The same vehicle can legally need two different document regimes in the same week: a CMR for the international leg and a DeCA for the cabotage leg that follows it.

The Ministry of Transport has been explicit that there is no grace period attached to the deadline, and enforcement under Spain's Ley de Ordenación de los Transportes Terrestres treats missing or incomplete documentation as a serious infringement, with fines generally running from 401 to 600 euros per shipment and liability potentially falling on both the shipper and the carrier. Running without the DeCA, or with incomplete data on it, is penalised per trip, not per inspection, so a fleet doing multiple domestic or cabotage legs a day without the right paperwork can rack up multiple infringements in a single shift.

Getting ready before the next roadside check

Spanish operators and lawyers advising on the rollout have been consistent on one point: companies did not need to wait for the deadline to start testing. Generating DeCA documents on real loads ahead of time lets administrative staff get comfortable with the format, lets drivers get used to how the document reaches them, usually as a QR code on a phone or printed with the QR visible, and surfaces process gaps before an inspector does.

For carriers running mixed international and domestic schedules, the practical risk is not understanding the rule, it is a driver or back-office team mixing up which document applies to which leg, or a dispatcher forgetting that a cabotage pickup needs its own DeCA generated before the wheels turn. Building that check into route planning, rather than treating it as a separate compliance task, is what keeps it from becoming a roadside problem.

Where this fits with how FleetlySolutions works

This is exactly the kind of regulatory friction that document automation exists to remove. FleetlySolutions already pulls structured data out of freight paperwork through OCR, which is the same kind of structured, auditable data the DeCA technical rules are built around: shipper and carrier identity, origin and destination, vehicle details and service conditions, all generated natively rather than typed in after the fact. For hauliers running Spanish domestic routes or cabotage legs alongside international work, having that data flow cleanly from route and load planning into the right document format, with the right retention, is the difference between a five minute admin task and a 401 euro problem at a roadside check.
