COC for BYD, MG & NIO: Can You Register Chinese Cars?
Buying a BYD, MG, or NIO in Europe? Find out whether Chinese car brands offer a COC for EU registration and what to do if the document is hard to get.
What you'll read:
he European car market looks considerably different today than it did five years ago. Chinese automotive brands have moved from a curiosity at motor shows to a genuine commercial presence on European roads, with BYD, MG, NIO, Ora, Omoda, Jaecoo, and a growing list of others actively selling new vehicles across EU member states. For buyers purchasing these cars new from authorised dealers, the registration process is generally straightforward.
For buyers purchasing second-hand Chinese brand vehicles, increasingly common as the first wave of these cars enters the used market, the COC question is more complicated, and the answers vary significantly from one brand to another.
Why Chinese Brand COCs Are a New Challenge for European Buyers
European registration authorities, dealer networks, and COC retrieval services have spent decades building infrastructure around the established brands. When a Romanian buyer needs a COC for a Volkswagen or a BMW, there are well-worn pathways: established dealer networks, manufacturer databases with decades of records, and service providers who handle these requests routinely.
Chinese brands in Europe are operating on much shorter timelines. Most of them entered the EU market in meaningful volumes only within the last three to five years. Their dealer networks are still being built. Their administrative infrastructure for handling document requests from foreign buyers is, in many cases, still being established. This does not mean a COC for Chinese cars is unobtainable — but it does mean the process requires more research and occasionally more patience than a comparable request for a German or French vehicle.
MG: The Most Established Chinese Brand for COC Purposes
MG is technically a British brand heritage operated by SAIC Motor, a Chinese state-owned manufacturer. It has been selling vehicles in Europe longer than most other Chinese brands and has a more established dealer and distribution network across EU member states, including Romania.
For COC purposes, MG is among the more accessible Chinese brands. The vehicles sold in Europe are type-approved under EU regulations, and MG’s European operations — managed through MG Motor Europe — maintain records sufficient for COC retrieval requests. If you have purchased an MG second-hand from another EU country and need a COC, contacting MG Motor’s national importer for your country is a reasonable first step.
For faster resolution, specialist platforms like auto-coc.eu can handle MG COC requests across a growing range of models. The most popular MG models in Europe – the MG ZS, MG4, and MG5 – are well-represented in the second-hand market now and their COC availability is generally solid.
BYD: Rapid Growth and Evolving Document Infrastructure
BYD is the world’s largest electric vehicle manufacturer by sales volume and has been expanding aggressively across Europe since 2022. The brand sells through a mix of authorised dealer groups and, in some markets, direct sales channels. Its European headquarters operates out of the Netherlands, and its type approvals for the European market are processed through standard EU channels.
For new BYD vehicles purchased from authorised European dealers, the COC should be included in the standard documentation package. The challenge arises for second-hand BYDs, particularly those that were first registered in one EU country and are now being re-registered in another.
BYD’s European customer service infrastructure is improving rapidly but remains uneven across markets. In countries where BYD has strong dealer representation — Germany, Norway, the Netherlands, Belgium — COC retrieval is relatively manageable. In markets where the brand is newer and dealer networks thinner, response times for document requests can be longer. Platforms like auto-coc.eu are increasingly able to handle BYD COC requests as the brand’s European presence matures and database access expands.
NIO: Premium Positioning and a Different Business Model
NIO takes a fundamentally different approach to the European market than most of its Chinese competitors. Rather than selling through traditional dealerships, NIO operates through a direct-to-consumer model centred on its own showrooms and service centres, known as NIO Houses and NIO Spaces. The brand also introduced its battery-as-a-service model to Europe, under which buyers own the car but subscribe to the battery separately — a setup with specific implications for COC documentation.
Under battery-as-a-service, the battery pack is effectively a leased component. This means the COC for a NIO vehicle may reflect specifications that are technically contingent on the battery subscription remaining active. For registration authorities in countries unfamiliar with this model, this can create questions about whether the vehicle’s documentation accurately reflects its configuration.
NIO’s European operations are centred on Norway, Germany, the Netherlands, Denmark, and Sweden. In these countries, the brand’s administrative infrastructure is reasonably developed. In markets further from NIO’s European footprint, obtaining a COC for a second-hand NIO can require direct engagement with NIO’s European headquarters rather than a local contact.
Other Chinese Brands: Ora, Omoda, Jaecoo, and Chery
Beyond the three most prominent names, a broader ecosystem of Chinese brands has entered or is entering the European market. Ora (a sub-brand of Great Wall Motor) sells the Ora Funky Cat in several EU markets. Omoda and Jaecoo are relatively new entrants backed by Chery Automobile, one of China’s largest manufacturers. SAIC also sells vehicles under the Maxus commercial vehicle brand alongside MG.
For these brands, the COC situation is more variable. Ora vehicles sold through authorised Great Wall Motor dealers in Europe have standard EU type approvals and the COC should be available through established channels. For Omoda and Jaecoo, which are newer to the market, the administrative infrastructure for COC retrieval is still maturing, and direct contact with the brand’s European importer may be the most reliable route for second-hand purchases.
The practical advice for any Chinese brand not covered by a specialist platform’s standard offering is to start with the European headquarters or national importer and request the COC retrieval in writing, with the VIN clearly stated. Follow up consistently and document all communication.

What to Do When the COC Is Hard to Get
For any Chinese brand vehicle where standard retrieval channels are slow or unresponsive, there are several practical escalation steps. First, identify the correct European legal entity responsible for type approval — this is the organisation named on the vehicle’s EU type approval certificate, which is distinct from the selling dealer. Second, contact that entity directly, in writing, referencing the EU type approval number and the vehicle’s VIN. Third, if the brand has a customer service escalation process, use it and keep records of every interaction.
For brands and models covered by auto-coc.eu, using the platform’s retrieval service is the most efficient route. As Chinese brands become more established in Europe and their database records become more comprehensive, the platform’s ability to service these requests continues to expand. Check availability for your specific make and model before pursuing manufacturer channels independently.
