Truck & Fleet Certificates of Conformity: What Dealers and Hauliers Need for Cross-Border Registration (Iveco, Scania, Volvo, MAN)
20 September 2026
By Loredana Zaharia, coc-auto.eu · Prices verified live 22 August 2026
A Certificate of Conformity is the manufacturer’s statement that one specific vehicle matches an approved EU type. When a truck or van is first registered in another Member State, the registration authority builds the file from that document. Without it, the unit goes down a national approval route — slower, more expensive, and priced per vehicle.
That is the whole mechanism, and it is why a missing certificate hurts a commercial fleet more than it hurts a private buyer. A car owner waits. A tractor unit on a yard does not earn, still carries its finance instalment, and blocks a transport contract that was priced on a start date. This article is written for the people who buy N-category stock in volume: truck dealers, importers, hauliers and fleet administrators moving units across DACH and Benelux borders.

Do N2 and N3 trucks need a Certificate of Conformity?
Yes. EU whole-vehicle type approval covers goods vehicles of every size, not only cars, and the Certificate of Conformity is the document that proves a given chassis belongs to an approved type. Registration authorities across the EU accept the technical data from it — masses, axle loads, emissions, dimensions — instead of re-measuring the vehicle.
The categories matter because they decide which approval file applies to your unit. Regulation (EU) 2018/858, Article 4, sets them out by maximum mass:
| Category | Definition (Reg. (EU) 2018/858, Art. 4) | Typical fleet unit | What it means for registration |
|---|---|---|---|
| N1 | Goods vehicle, maximum mass not exceeding 3.5 t | Sprinter, Transit, Daily, Master | Same registration logic as a car; the COC carries CO2 and mass data used for national taxes |
| N2 | Goods vehicle, exceeding 3.5 t but not exceeding 12 t | 7.5 t distribution truck, box body, tail-lift unit | Very often a multi-stage build: chassis approval plus bodybuilder stage |
| N3 | Goods vehicle, exceeding 12 t | Tractor unit, 26 t rigid, tipper | Multi-stage is the norm; the completed vehicle needs its own approval evidence |
| O1 | Trailer, maximum mass not exceeding 0.75 t | Small utility trailer | National rules differ on separate registration |
| O2 | Trailer, exceeding 0.75 t but not exceeding 3.5 t | Plant trailer, car transporter trailer | Usually registered in its own right |
| O3 | Trailer, exceeding 3.5 t but not exceeding 10 t | Drawbar trailer | Registered and plated separately in international traffic |
| O4 | Trailer, exceeding 10 t | Semi-trailer, curtainsider, tanker | Registered and plated separately; approval evidence per unit |
Two consequences follow from this table, and both cost money if you learn them at the counter.
First: multi-stage builds. Regulation (EU) 2018/858 provides for multi-stage type-approval of incomplete and completed vehicles (Article 22). A tipper or a refrigerated box is rarely one manufacturer’s work — the chassis manufacturer approves the incomplete vehicle, the bodybuilder completes it, and the file the authority wants is the one for the completed vehicle. A chassis certificate on its own describes a vehicle that no longer exists in that form. If you buy N2/N3 stock with bodies fitted after delivery, ask which entity signed off the final stage before you agree a registration date.
Second: age. EU whole-vehicle type approval was phased in by category between 2009 and 2014 under Directive 2007/46/EC, the predecessor of the current regulation. Vehicles first registered before their category’s cut-off may hold a national approval instead — in which case a manufacturer’s COC was never issued and cannot be issued retroactively. For N2/N3 the commonly cited dates are 29 October 2012 for new complete vehicles and 29 October 2014 for completed multi-stage vehicles (Annex XIX of Directive 2007/46/EC; the phase-in table is reproduced by type-approval publishers such as InterRegs, which lists 29/10/2010 for new types, 29/10/2012 for new registrations of complete and incomplete vehicles and 29/10/2014 for completed vehicles). Practical rule for a buyer: on pre-2015 heavy units, treat the certificate as something to confirm at purchase, not to assume.
If you want the underlying document explained field by field, our complete Certificate of Conformity guide covers the structure, and the piece on the vehicle type approval number explains how the approval reference on the certificate ties back to the type file.
What happens when a fleet unit arrives without its COC?
The unit does not get registered on the standard route. It goes to a national procedure — individual vehicle approval or an equivalent engineer-verified data route — which is per vehicle, booked by appointment, and priced accordingly. That is the whole difference: type approval scales across a batch, individual approval does not scale at all.
What the fallback looks like depends on the destination market. In Germany the unit lands in a §21 StVZO (Straßenverkehrs-Zulassungs-Ordnung) route with a full expert report. In Austria it is an Einzelgenehmigung. In Spain the homologation office may accept an engineer-signed ficha reducida. In the Netherlands the Rijksdienst voor het Wegverkeer (RDW) will not proceed without the certificate, and the tax calculation itself depends on data that sits inside it. The names differ; the pattern does not. You swap a document that already exists for an inspection slot that has to be booked, and the slot is the bottleneck, not the paperwork.
Three failure modes we see repeatedly on commercial stock:
- The seller hands over a copy. Registration offices work from the manufacturer’s original or a manufacturer-issued duplicate. A scan inherited from a previous owner is not a substitute. Our breakdown of what authorities actually check in a COC lists the fields that get files rejected.
- The certificate describes the chassis, not the vehicle you bought. Classic on N2/N3 with a body fitted at stage two. Masses and dimensions on the paper do not match the unit at the weighbridge.
- The unit was auction stock and nobody asked. Ex-fleet and ex-leasing lots move fast and the document file moves slower. Our note on auction paperwork covers what to demand before the hammer, not after.
Where no COC exists at all — genuine pre-type-approval units, non-EU-market builds, heavy special conversions — the honest answer is that the national route is the route. Our comparison of COC vs national data sheet vs engineer report sets out what each document does and does not achieve across borders. We do not supply certificates for vehicles that were never built to an EU approved type, and neither does anyone else.
What does an immobilised unit actually cost per day?
A blocked registration is not a paperwork problem, it is a standing-cost problem. The asset is paid for, insured and parked, and it produces nothing while the file is open. Run the number before you decide whether a certificate is expensive.
The arithmetic below is illustrative — plug in your own contract figures. It is not a benchmark, it is a template:
| Cost line | Where your number comes from | Illustrative figure |
|---|---|---|
| Finance / lease instalment | Your contract, per unit per month | €1,350/month → €45/day |
| Insurance on a non-earning asset | Fleet policy, per unit | €150/month → €5/day |
| Yard, parking, admin handling | Site cost allocation | €150/month → €5/day |
| Standing cost, before lost revenue | ≈ €55/day |
Now apply it to the delay, at the illustrative €55/day:
| Registration delay | Standing cost | Compared with |
|---|---|---|
| 1 week | ≈ €385 | A Scania certificate at €234 net |
| 2 weeks | ≈ €770 | An Iveco certificate at €324 net |
| 4 weeks | ≈ €1,540 | Four MAN certificates at €284 net each |
| 6 weeks | ≈ €2,310 | Nine Volvo Truck certificates at €234 net each |
And that is before the revenue side. A haulier who has quoted a contract on a start date is not losing €55 a day, they are losing the margin on the loads the unit was booked for, plus whatever a subcontracted replacement costs. A dealer is losing a floor-plan turn on a unit that cannot be handed over.
The reason this matters at fleet scale is that the exposure multiplies while the certificate cost does not. Ten units missing paperwork is ten times the standing cost and roughly ten certificates. The ratio does not move in your favour by waiting.

Prices read from the live catalogue on 22 August 2026. Current figures are always the ones on the truck and van certificate category; the full catalogue across M1, L, N and motorhome categories sits at all COC certificates.
On timing, the honest version: processing depends on the brand and the issuing manufacturer department. Many certificates are ready within a few working days; some take up to two weeks. Physical originals then ship — free delivery runs 3–7 business days after processing, express 2–4 business days at €19.99, with the PDF released first. Our article on how long a COC takes and what influences the timeline explains which factors move the date.
The operational point for fleets: processing time runs in parallel with transport, not after it. A unit bought in Germany on Monday and trucked to Rotterdam over ten days has already absorbed the certificate lead time if the order goes in on the purchase day. Order it on arrival and you have added the lead time to the standstill instead.
What you need to start is the full 17-character VIN. Nothing else, in most cases — occasionally a copy of the current registration certificate or previous approval documents. If you want to check a VIN before committing to a purchase, use the VIN check.
How does a complete COC dossier become a negotiation lever?
Because the document gap is priced by whoever discovers it last. If you identify at the negotiation table that eight units in a fifteen-unit lot have no certificate, the cost of fixing that is a line item in your offer. If you discover it at the registration desk, it is your cost, alone, under time pressure.
A workable process for stock acquisition, in the order that keeps you in control:
- Collect the VIN list before price agreement, not at collection. Fifteen VINs on a spreadsheet is a two-minute request that most sellers grant without thinking about why you want it.
- Check each VIN against the document file. Certificate present, original or manufacturer duplicate, and — for N2/N3 — does it describe the completed vehicle or only the chassis?
- Price the gaps. Missing certificates at €234–€324 net each, plus the standing-cost days you calculated above for anything that would go down a national route. That number belongs in your bid, not in your P&L three weeks later.
- Order the gaps on the day of purchase. Processing runs while the units are on transporters or in preparation.
- Book registration appointments last. An appointment booked before the file is complete is an appointment you will lose, and the replacement slot is weeks out in most DACH registration offices.
Two things this discipline buys a dealer. It converts a vague “the paperwork is somewhere” from the seller into a quantified deduction. And it lets you quote a delivery date to your own buyer that you can actually hold, which is the part fleet customers remember.
For dealers running this monthly rather than occasionally, the certificate order stops being a one-off transaction and becomes a standing volume process against a VIN list — brand-by-brand lead times planned at purchase, not at registration. That is the point at which per-unit pricing and a single point of contact are worth discussing.
One current development to keep on the radar. Under Regulation (EU) 2018/858 and Implementing Regulation (EU) 2021/133, the Certificate of Conformity is moving to structured electronic data — an XML format exchanged between authorities — and from 5 July 2026 Member States are to make it accessible by VIN through the common secure electronic exchange system. As of August 2026 this is a rollout, not a finished state. Until your destination authority confirms it can retrieve the data by VIN for the brand and build in front of you, plan your fleet registrations on the document you hold in the file.
FAQ: truck and fleet Certificates of Conformity
Do N2 and N3 trucks need a Certificate of Conformity to be registered in another EU country?
Yes. EU type approval covers goods vehicles of all masses. The certificate is the standard evidence a registration authority uses to accept the technical data at first registration in the destination Member State.
Can a truck be registered without a COC?
Yes, but not on the standard route. The unit goes to national individual vehicle approval or an equivalent engineer-verified procedure, which is booked per vehicle, inspected per vehicle and priced per vehicle.
Is a chassis certificate enough for a truck with a body fitted later?
Usually not. N2/N3 units are frequently built in multiple stages, and the authority wants approval evidence for the completed vehicle. Masses and dimensions on a chassis-only document will not match the finished unit.
Do semi-trailers and drawbar trailers need their own certificate?
O-category trailers are separately approved vehicle categories under Regulation (EU) 2018/858, and O3/O4 units used in international haulage are registered and plated in their own right. Confirm the specific requirement with the destination registration authority, since national rules differ on the smaller categories.
How much does a truck COC cost?
As of August 2026, between €234 and €324 net (excl. VAT) per unit for the PDF in our catalogue, depending on brand, with the printed original €10 higher. Scania, Volvo Truck and Mercedes-Benz sit at the lower end; Iveco, DAF and Maxus at the upper end.
How long does it take?
Brand-dependent. Many certificates are issued within a few working days, some take up to two weeks, and physical originals ship afterwards. The only reliable way to keep it off your critical path is to order on the purchase day rather than on arrival.
What do you need from us to start?
The full 17-character VIN. In some cases a copy of the current registration certificate or previous approval documents. For multi-unit orders, a VIN list is enough to get lead times per brand.
Do you supply certificates for every commercial vehicle?
No. Certificates exist only for vehicles built to an EU approved type. Very old units, heavy special conversions and vehicles built for non-EU markets fall outside that, and for those the national approval route is the route.
Ordering for a fleet or a stock purchase?
We supply Certificates of Conformity in volume for truck dealers, importers and fleet operators across the EU — Iveco, Scania, Volvo Truck, MAN, DAF, Renault Trucks, Mercedes-Benz and the rest of the N1/N2/N3 catalogue.
Send us the VIN list and the destination market. You get lead times per brand, per-unit pricing for the volume, and a single dossier owner instead of ten separate order confirmations. All quotes net, excl. VAT, invoiced under reverse charge for EU-registered businesses.
