How to Obtain the O1 Category Caravan Type Approval Certificate (EU)

Obtaining a type approval certificate for O1 category caravans from European Union member states offers significant advantages, particularly for international sales opportunities. In this article, we will provide a detailed explanation of the process for obtaining a type approval certificate for caravans.

Starting the Type Approval Process

The first step is to ensure that your company fully complies with all legal requirements. The approval authority (competent body) requires commercial registration documents and quality system certifications related to the production processes.

We provide the necessary support during this phase. While the process may vary periodically, key requirements include the WMI code and the ISO 9001:2015 quality management system certificate.
These documents are essential to initiate the type approval process.

While administrative procedures are ongoing, you should also begin translating your prototype design into drawings. From this stage onward, the process enters a technical phase.

Technical Stages of the Caravan Type Approval Certificate

Those unfamiliar with the automotive sector may frequently encounter common pitfalls. Particularly in the case of molded caravan designs, costly and difficult-to-reverse errors can occur. To avoid these, it is essential to seek technical consultancy before creating a physical prototype.


Why is this important? Without adequate knowledge of technical regulations and legislation, design errors related to measurements or incorrect product selection (such as the caravan chassis) are likely.
These types of mistakes can negatively affect the entire design process.

When applying for an O1 category caravan type approval certificate, many details, such as the placement of lighting fixtures on the vehicle, must be precisely measured. Furthermore, components such as windows, brakes, axles, coupling, and fenders must comply with the relevant regulations. The automotive industry is required to adhere to the conditions set out in these regulations.


Therefore, your design should be created within the framework of these regulations. At this stage, we provide comprehensive technical support throughout the process.

Prototype Production

Once the technical drawings are verified, your design can be turned into a physical test prototype. At this stage, product selections will have also been made according to regulatory requirements.
The produced caravan must meet both general safety standards and user comfort requirements. User comfort, too, is determined by specific regulations.

The caravan test prototype, prepared in compliance with minimum requirements, is subject to detailed inspections.

After test experts have conducted their inspections, if no discrepancies are found between the prototype and the technical information documents we have prepared, the technical reporting process is completed.

Certification and Approval Process

The relevant approval authority in the European Union member state reviews the submitted documents.
The information document, test reports, and administrative documents are presented to the approval authority, and if the application is successful, the type approval certificate is issued.

Chassis Number and Certificate of Conformity (COC) Creation

The first step for an O1 certified caravan is to assign a chassis number. Following that, a Certificate of Conformity (COC) document containing the technical details of the vehicle is prepared.
We also offer training on these documents after the certification process is completed. (Acc. to EU 2020/683)

Where to Obtain a Caravan Type Approval Certificate and Its Validity

Our consultancy services are fully online, meaning there is no need for us to be in the same country. All procedures are legally recorded and can be conducted remotely.


The trailer caravan type approval certificate is generally obtained from European Union member states and is valid internationally. However, some countries (such as the USA, Russia, and China) have their own standards, and separate certifications are required for those markets.

CoP (Conformity of Production) Procedures

Before applying for a type approval certificate, your company’s quality management system must be approved. This approval is granted through your ISO 9001:2015 certificate. In the following years, as a manufacturer, you will undergo regular audits.
These audits are conducted by approval bodies and authorized organizations and are quite thorough. They examine whether your production complies with legal requirements, as well as your production records and quality control system. Administrative and financial penalties may be imposed during this process.
Therefore, maintaining consistency between the certificate and the produced products, as well as keeping accurate records, should be among your company’s top priorities.

O1 Category Certificate Costs

Caravans also fall under the trailer category. Since each manufacturer has different designs and processes, we can determine the exact cost after analyzing your company’s current situation.
Considering that external payments fluctuate constantly, approximate costs range between €7,000 and €10,000. However, these figures can change depending on the scope of the administrative processes. We recommend requesting a quote for an accurate cost assessment.

Type Approval Certificate Acquisition Timeline

The time required to obtain a type approval certificate is typically 6-8 weeks, provided that the file is complete and the application is submitted promptly. However, when factoring in the vehicle preparation stage, the entire process can take 3-4 months.
Public holidays and heavy workloads in the European Union region may affect these timelines.

Importance of the Caravan Type Approval Certificate

Without adherence to specific standards, it is impossible to ensure proper quality control in production.
Even beyond legal obligations, obtaining a type approval certificate is essential to demonstrate the quality of your products. Therefore, it is highly recommended to obtain a comprehensive type approval certificate for your production.

I have been acquainted with homologation in the automotive sector for over 10 years now. We have accomplished great things in many projects within various teams. Adapting to the recently updated homologation processes has been particularly exciting. Integrating past experiences with new procedures fosters a fertile ground for innovation and productivity. Having a special interest and expertise in both automotive and technology,

I am thrilled by the prospect of these fields converging in the future. It is a privilege to be a part of the journey in automotive and technology!

For this reason, I have decided to launch a blog project that I have long envisioned, where I can share my experiences and assess developments in the industry.

Previously, in the early years of my career, I managed a well-loved project named Homologasyon.xyz, which offered content in Turkish. I had decided to discontinue this project for various reasons.

Now, I am excited to engage with an international audience through a new blog project, sharing knowledge and insights. I hope my efforts will contribute positively to the industry.

Please feel free to contact me with your views and suggestions.
