Does mechanical condition affect duty?

No. A damaged CT4 clears at the same rate as an intact car from the same plant, because what counts is the country of final assembly. Condition does affect the purchase price, and through it the customs value and the taxes charged on it.

How long does a VIN check take?

A matter of seconds. You enter the number and get the country and city of the assembly plant plus the answer to whether that CT4 meets the condition for the customs preference. The check is free, needs no account and can be repeated for every lot you consider.

Does a sale in the USA mean assembly in the USA?

No. American sales also move cars built in Canada, Mexico, Europe and Asia. Where a car was auctioned has nothing to do with the origin condition, which is why the assembly plant of a CT4 is checked separately, on the VIN.

Who deals with customs clearance?

We do. We put together the proof of origin, prepare the customs declaration and keep contact with the agency. For a CT4 that qualifies on its VIN we apply for the 0% rate, and the customs office decides on the documents.

What about models built in two countries at once?

That is a common case, and it is exactly where the VIN becomes essential. Two CT4 cars from the same model year can carry different rates, 0% and 10%, because they came off lines on different continents.

Cadillac CT4 off an American line — what it changes in duty

EU–US Agreement on Reciprocal Trade has applied since 2026-07-01 and cuts duty to 0% for cars finally assembled in the States. The Cadillac CT4 meets that condition only in the cars genuinely built at an American plant; the rest clear at 10%. Verification runs on the VIN, not on the version name.

Where is the Cadillac CT4 assembled?

The Cadillac CT4 comes out of plants that do not always sit in the same country, and those plants set the rate. A car from an American line enters the EU at 0%, a car from a plant elsewhere at 10%. Every row here is built from real cars in our database, not from a manufacturer's plan.

How do you check a specific car?

The VIN settles the matter in seconds. CT4 cars from plants in the USA carry the prefixes 1G6 here, but we look deeper — at the final assembly plant tied to the whole number. Only that answers the question of 0% or 10%.

How much will you save?

The saving is a percentage, so it grows with the value of the car. A Cadillac CT4 from an American plant comes in at 0% instead of 10%, and lower duty shrinks the 23% VAT base. Excise stays: 3.1% on smaller engines, 18.6% on larger ones. The calculator does the rest.

Work out the import cost

What the import cost is made of

The bill is made of a few fixed percentages and one variable, which is the customs value of the car. Duty is 0% on a CT4 assembled in the USA and 10% on the rest, excise is 3.1% or 18.6% by engine size, and 23% VAT is charged on the value with duty and excise added.

Component	Rate
Duty — car assembled in the USA	0%
Duty — everything else	10%
Excise	3.1% up to 2.0 l, 18.6% above 3.5 l
VAT	23%

Rates, not amounts — the calculator works the sum out on current data.

Zero-duty paperwork — our job

Our customs agency handles the formalities. We gather the assembly data for the Cadillac CT4, prepare the declaration and see the clearance through. The rate finally granted is the customs office's decision, taken on the documents submitted.

What to watch for when buying at auction

Before you raise your bid, look at the damaged area. On a CT4 it is most often features.lots.characteristics.damage_type.front_end, and then the key question is whether the body structure was disturbed. Origin is a separate check, run on the VIN — the two things are independent of each other.

From the USA or from Europe?

Europe hands you a car ready to register; the States hand you a wider choice of versions and of damaged cars. On a CT4 origin joins the list: a car assembled in the USA clears at 0%, one from outside the preference at 10%. That is the first thing to check when you compare offers.
