Why this situation is different from a normal car import
Most car import guides assume you have a European Certificate of Conformity (CoC) — the manufacturer's document proving your car matches an EU-approved type. If you're bringing a car from the US, Japan, the UAE, Brazil, or anywhere else outside the EU's type-approval system, you almost certainly don't have one, and the standard "get your CoC, fill in Modelo 9" process doesn't apply cleanly to you.
Vehicles from extra-EU markets such as the United States, Japan, or the United Arab Emirates don't have a European Certificate of Conformity and don't have EC type-approval. That's a completely normal situation — it doesn't mean the car can't be legalised. It means you need individual approval (homologação individual), a more involved but well-established route through the IMT. The absence of a CoC doesn't necessarily prevent legalisation, but the IMT also provides procedures for vehicles without a CoC.
If you're still deciding whether to ship a car at all versus buying locally, our broader living in Portugal guide covers the trade-offs. This piece assumes you've already committed to importing.
The core distinction: national homologation vs. individual approval
There are really two paths once a car is in Portugal:
- National homologation exists for that exact model — someone has already homologated the identical make, model, and spec in Portugal. If the car has already been homologated in Portugal — it has to be an exactly identical model — it will have a National Homologation Registration Number you can use without needing the CoC. You request that number from the IMT using your foreign registration documents.
- No matching homologation exists — typical for US-spec, Japanese-market, or heavily customised vehicles. If you don't have either of these (common with cars manufactured for sale outside the EU), the process is more complicated. This is the individual approval track this guide is about.
For imports of a single vehicle for private use, you need to apply for an individual homologation. That homologation may be exempt from some procedures, but it remains a bureaucratic and complex task for an ordinary person.
What the IMT actually asks for
The individual approval dossier is heavier than a standard CoC-based file. Based on IMT practice, expect to submit:
- A formal homologation request addressed to the IMT
- Proof of ownership (foreign title, registration certificate, or equivalent)
- A detailed technical data sheet covering the vehicle's characteristics
- Origin documentation — import title, customs declaration, purchase invoice
- Technical drawings or schematics if the vehicle has been modified
- A report from an accredited test laboratory, where applicable
- Proof of payment of the homologation fees
The required documents vary by vehicle type and reason for homologation, but the base list includes a request for individual homologation addressed to the IMT, proof of ownership, a detailed technical data sheet, origin documentation, technical drawings for modifications, an accredited lab report where applicable, and proof of payment.
For US-origin cars specifically, a certified translation of documents such as the state title and the American certificate of conformity (if one exists) is frequently needed, along with a manufacturer or national importer declaration.
Depending on the vehicle, the IMT can require specific laboratory tests: emissions measurement and verification of the applicable EURO standard, braking tests, weight and dimension checks, headlight positioning tests, and — for structural changes — strength calculations and weld verification. A prior technical inspection at an authorised Vehicle Inspection Centre (CITV) is usually the starting point of the process.
Step-by-step: what actually happens
- Before the car arrives, or right after — start compiling the technical dossier. You may need to contact the manufacturer or a national importer for a data sheet if one doesn't exist locally.
- Homologation request to the IMT. If the vehicle doesn't correspond to an existing approval, you must request homologation from the Regional and District Services of the IMT covering your area of residence, and once it's done, you can proceed with regularisation at Customs.
- CITV inspection. Once homologation is granted (or a national number assigned), the car goes to a Category B inspection centre. If everything is in order, a Modelo 112 inspection certificate is issued, valid for 90 working days, which must then be presented to the IMT to request the registration certificate.
- DAV and ISV. The DAV (Declaração Aduaneira de Veículo) must be submitted within 20 working days of the car entering Portuguese territory. A DUC (Documento Único de Cobrança) is generated automatically, and the tax must be paid within 10 working days of the DAV submission.
- Registration. After paying the ISV, you have 60 days to pay the registration fee at the IMT and request the registration certificate.
Fees differ depending on whether you already hold homologation: the fee is €45 when you have a CoC or national homologation, paid at the counter in cash, Multibanco, or cheque. Without national homologation, expect a materially higher registration fee — IMT fees run around €45 with national homologation versus €165 without it, on top of the roughly €76 (plus VAT) inspection cost, in 2026.
Comparison: CoC route vs. no-CoC individual approval
| Has CoC / national homologation | No CoC — individual approval | |
|---|---|---|
| Starting document | Manufacturer's CoC or existing national number | Technical dossier, origin docs, lab reports |
| IMT fee (2026) | ~€45 | ~€165 |
| Extra steps | Modelo 9 + Modelo 112 inspection | Homologation dossier + possible lab tests (emissions, braking, dimensions) before Modelo 112 |
| Typical timeline | Weeks | Often months, depending on IMT workload and test requirements |
| Common bottleneck | Ordering the CoC (1–4 weeks) | Sourcing technical data / arranging accredited lab tests |
Duty, ISV and VAT — what you'll actually owe
Homologation is a technical/legal hurdle; it doesn't replace the tax bill. Three separate charges can apply on a non-EU import:
- Customs duty: clearing a car through customs from outside the EU means paying import duty, usually around 10 percent, plus Portuguese VAT (23 percent) and ISV.
- VAT (IVA): Portugal applies 23% VAT on the comprehensive import value, including the vehicle cost, ISV, and customs duties — creating a compounding effect.
- ISV (the vehicle registration tax, based on engine size and CO₂): typically up to around 10–15% depending on the vehicle, calculated separately via the DAV process described in our full car import guide for CoC-based imports.
The one major relief valve is the change-of-residence exemption. New residents may import one vehicle they've owned for at least six months, within twelve months of moving, and pay zero ISV, VAT, and duty — only inspection and paperwork fees. This exemption is available regardless of nationality, but you'll need to document your prior residence abroad and the vehicle's ownership history. It doesn't remove the homologation requirement if your car has no CoC — you'll still need individual approval — but it can eliminate the tax bill entirely, which is often the bigger number.
Electric vehicles get separate treatment: battery-electric cars are exempt from both ISV and the annual road tax (IUC).
Common mistakes people make
- Assuming "no CoC" means "impossible." It doesn't. It means more paperwork and longer timelines, not a dead end.
- Missing the 20-working-day DAV deadline while still sorting out homologation. The clock starts the moment the car enters Portugal, regardless of whether your dossier is ready.
- Letting the Modelo 112 inspection certificate expire. It's valid 90 working days — if IMT registration drags past that, you'll need to re-inspect.
- Underestimating US-spec paperwork. Certified translations of state titles and manufacturer declarations take time to arrange; start early.
- Forgetting the change-of-residence exemption even applies to non-EU nationals moving to Portugal for the first time, not just returning Portuguese citizens.
Given the complexity, many people bringing a non-EU-spec vehicle choose to have a specialist handle the homologation dossier and IMT liaison directly rather than navigating it solo — worth weighing against the time cost if your move already involves a visa application or residence permit process running in parallel.
Frequently Asked Questions
You generally cannot register or permanently plate the car until homologation and inspection are complete, though some processes allow limited use while ISV eligibility is being assessed. Check current rules with the IMT before assuming you can drive on foreign plates for an extended period, as temporary admission rules differ for residents versus visitors.
There's no fixed statutory timeline — it depends on IMT workload, whether lab tests are required, and how complete your dossier is on first submission. Budget for months rather than weeks if your car requires structural or emissions testing.
Yes, in fees alone the no-homologation IMT registration charge has been roughly €165 versus about €45 with an existing CoC or homologation, plus any accredited lab testing costs. The bigger cost driver is usually time and, potentially, a specialist to compile the technical dossier.
Homologation and tax are separate processes. Unless you qualify for the change-of-residence exemption, standard non-EU import charges — customs duty, VAT, and ISV — still apply on top of the homologation and inspection fees.
Yes for the CoC specifically — cars manufactured before 1996 are not required to have a CoC — but you'll typically still need a national homologation number or an individual approval process, and CO₂ figures may need to be established via inspection since older cars weren't originally tested for it.
Bringing in a car without a CoC is one of the more paperwork-heavy corners of relocating to Portugal — and it's easy to blow the 20-day DAV deadline while still chasing homologation documents. If you'd rather have someone handle the IMT dossier, inspection scheduling, and ISV filing while you focus on the move itself, our car import assistance service can take it off your hands.
