Assembling your own car from disparate components and body parts is not just a hobby, but a complex engineering process that in Russia requires a strict legal procedure. Many enthusiasts who collect constructors from Japan or Europe are faced with the impossibility of legally operating their creation on public roads. The problem lies in the lack of factory documents confirming the safety and compliance of the design with the technical regulations of the Customs Union.
The process of turning a set of spare parts into a full-fledged vehicle with numbers and a title is called SBCTS (Vehicle Design Safety Certificate). Without this document, as well as a valid EPTS, any attempts to register the car are doomed to failure. In 2026, the requirements for homemade vehicles became even stricter, and the workarounds that worked several years ago ceased to function.
In this article we will analyze the current algorithm of actions that will allow you to avoid fines and confiscation of equipment. You will learn which laboratories have the right to issue conclusions, how the examination is carried out at NAMI, and why simple “customs clearance” of spare parts no longer gives the right to registration. The key point is that the assembly must be done in a certified facility and not in a garage by an individual.
Legal basis and changes in legislation
The main document regulating the safety of wheeled vehicles is the Technical Regulations of the Customs Union TR CU 018/2011. It is this regulation that determines the requirements for construction, braking systems, lighting and environmental class. It is important for owners of constructors to understand that the concept of “car made from spare parts” is interpreted in the law as single vehicle, made in a single copy.
On July 1, 2021, and in subsequent years, amendments came into force that effectively closed the “garage assembly” loophole. Now, if you import the body, engine and chassis separately, customs considers it a set of spare parts. To obtain vehicle status, a certification procedure is required. US (Scientific Automotive Institute) acts as the lead organization coordinating testing and issuing permits for work.
It is important to note that the legislation clearly distinguishes between repairs and design changes. Replacing units with similar ones as part of a repair does not require approval, but assembling a car from different donors is already creating a new object.
⚠️ Attention: An attempt to register a car assembled independently without prior permission from US and the SBCTS protocol will lead to refusal to issue license plates and possible confiscation of the equipment for disposal.
Below is a table showing the main differences between the international import of a finished car and a designer one:
| Parameter | Finished car (used) | Constructor (Spare parts) | Homemade vehicle (Assembly) |
|---|---|---|---|
| Import status | Vehicle | Accessories | Not applicable (within the Russian Federation) |
| Customs duty | 54% of cost (or by volume) | Depends on the HS code (usually lower) | - |
| The need for SBCTS | Required (simplified) | Required (full cycle) | Required (full cycle) |
| Ecological class | Not lower than Euro-4/5 | Laboratory confirmed | Laboratory confirmed |
Stage one: Import and customs clearance
The legalization process begins long before the visit to the traffic police, even at the stage of crossing the border. If you import a car disassembled, customs authorities classify the cargo based on the degree of disassembly. There is the concept of “incomplete configuration”, when the car is disassembled for convenient transportation, but retains the characteristics of the vehicle. In this case, a high duty rate is applied as for a finished car.
However, if the body is separated from the frame, the engine is removed and the wheels are packaged separately, the load is classified as parts. This allows you to save on customs duties, but creates difficulties with further registration. To receive SBCTS you will need to prove that the imported components comply with the declared characteristics and are not on sanctions lists or lists of stolen vehicles.
During customs clearance, it is necessary to provide invoices, contracts and technical documentation for the units. Particular attention is paid to identification numbers (VIN, engine and body numbers). They must be legible and free from signs of corrosion or interruption.
⚠️ Attention: If the unit numbers do not match the documents or have signs of artisanal restoration, customs has the right to initiate a criminal inspection procedure, which will delay the process for months.
After passing through customs, you will receive a package of documents, which will become the basis for further steps. Without a correctly completed customs declaration (CCD) with the correct HS codes, the laboratory simply will not accept an application for testing. It is important to keep all original papers, since in 2026 the principle of electronic document management applies, but paper copies are often required for reconciliation.
Keep all receipts and documents for the purchase of spare parts, even small ones. In some cases, the laboratory may request confirmation of the origin of critical safety components such as airbags or seat belts.
Obtaining permission from US
The next critical step is to obtain prior approval from an accredited testing laboratory authorized US. This is an organization that gives the go-ahead for the creation of a single copy of a car. Without this permit, building a car is considered illegal, even if you are doing it for yourself.
The procedure for submitting an application to a laboratory requires careful preparation. You must provide a detailed description of the design, drawings, electrical connection diagrams and a list of units used. Experts are assessing how safe it will be to operate this combination of nodes. For example, mounting a powerful engine on a lightweight frame may be considered dangerous.
During the application review process, specialists may request additional data or require changes to the project.
What documents are needed to contact the laboratory?
To submit an application you will need: the applicant’s passport, documents for the units (customary declaration, invoices), color photographs of components, a brief description of the design and technical characteristics of the future vehicle. A notarized copy of the manufacturer's release may also be required if a vintage car is being recreated.
After successfully passing the examination, you receive a “Permission to make changes to the design of the vehicle” or permission to manufacture a single copy. This document has a validity period and is the basis for starting physical assembly or continuing work if the car is already partially assembled.
Assembly and technical expertise
With the permit in hand, you can begin the final assembly. It is important to understand that the assembly must be carried out in compliance with the technological maps. If you are not qualified, it is better to entrust this stage to a specialized service that can provide certificates of completed work. This will prove that the car was professionally assembled.
After assembly, the car is sent to a testing laboratory to undergo a full cycle of checks. Engineers check the brake system, steering, lighting, noise and emissions. Particular attention is paid to compliance with the environmental class specified in the documents. For older Japanese engines, this often becomes a stumbling block, requiring the installation of additional neutralization systems.
☑️ Checklist before going to the laboratory
If the car successfully passes all tests, the laboratory issues SBCTS protocol. This is the main document that confirms that your “constructor” is safe and complies with the requirements of TR CU 018/2011. From this moment on, the car legally ceases to be a set of spare parts and becomes a vehicle ready for registration.
Registration of EPTS and registration with the traffic police
With a ready-made SBCTS protocol and a package of customs documents, you contact an organization that has the status of an EPTS registration point (Electronic Vehicle Passport). Based on the provided papers, an electronic passport is issued, in which an individual (owner) or an assembly plant can be indicated in the “Manufacturer” column.
The final stage is a visit to the registration and examination department of the traffic police. You provide the car for inspection, where the inspector checks the unit numbers with the data in the EPTS and SBCTS. If there are no questions, you will be issued state registration plates and a vehicle registration certificate (VRC).
It is worth noting that the cost of the legalization procedure can be comparable to the cost of the car itself.
⚠️ Attention: The validity period of the SBCTS Protocol is limited. If you do not have time to issue an EPTS and register the car with the traffic police during the validity period of the protocol, you will have to go through the test procedure again.
Without a valid SBCTS Protocol and a completed EPTS, registration of a home-made car with the traffic police is impossible under any circumstances.
Typical mistakes and risks during legalization
Many owners of construction kits try to save money by turning to dubious intermediaries who promise “documents without a car.” In 2026, the traffic police and customs databases are combined, and a fake SBCTS or EPTS can be identified in a few minutes. The use of such documents leads to cancellation of registration and criminal liability for forgery of documents.
Another common mistake is incorrect classification of spare parts upon import. An attempt to underestimate the customs value or change the HS code may lead to additional charges and fines, which completely eliminates the benefits of purchasing a designer item. In addition, “gray” import schemes often block the possibility of obtaining legal SBCTS.
It is also risky to make changes to the design after receiving the documents. Installing a non-standard turbo compressor, changing the disc offset or replacing the engine without re-approval in the laboratory makes the SBCTS invalid. At the first check on the road, such a car will be sent to the impound lot.
Frequently asked questions (FAQ)
Is it possible to register a construction kit if it was built before 2021?
If the car was built and owned before the new rules came into force, the procedure may be simplified, but you will still need to obtain a SBCTS. The fact of a long-standing assembly will need to be proven documented or through court, which is a complex process.
How long does the entire registration procedure take?
On average, the process takes from 2 to 4 months. This includes time for customs clearance, obtaining a NAMI permit, testing in the laboratory and issuing an EPTS. The timing may vary depending on the workload of the laboratories and the complexity of the design.
What to do if the laboratory refuses to issue an SBCTS?
Failure is usually motivated by failure of the design to meet safety requirements. You will be provided with a list of comments. It is necessary to eliminate these shortcomings (replace units, modify components) and undergo the examination again. In some cases, it is easier to sell the car as a set of spare parts.
Do I need to pay a recycling fee for a designer?
Yes, a recycling fee is paid when importing a chassis or body with an engine. The rate depends on the engine size, the age of the car and the status of the owner (individual or legal entity). For commercial shipments or in case of violation of import conditions, the rate may be significantly higher than the preferential rate.
Where can I find a list of accredited laboratories?
The list of testing laboratories authorized to issue SBCTS is posted on the official website of the Russian Accreditation Service. Look for organizations that have accreditation code OK 031 (EAEU) for the “Vehicles” category.
