Buick Century from the USA — 0% duty or 10%

US-assembled Buick Century cars usually reach us from the plant in Oklahoma City. If your car came off that line, duty is 0% instead of 10%; if it came from a plant in another country, the preference does not apply. The split runs by single VIN, not by model.

Where is the Buick Century assembled?

Century cars off American lines carry the VIN prefixes 1G4 in our database. A prefix shows the manufacturer and the country, but the 0% rate is decided by the final assembly plant read for the specific number. The table shows how many cars from each plant have passed through us.

How do you check a specific car?

The quickest filter is the first three characters of the number — on a Century with American assembly that is usually 1G4. A filter is not proof, though: we check the plant tied to the full VIN, because only that answers the condition. The check runs in seconds and costs nothing.

How much will you save?

The saving is a percentage, so it grows with the value of the car. A Buick Century 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

Three tax lines and one variable. Duty follows the assembly country of your Century: 0% for an American line, 10% for any other. Excise goes by engine size — 3.1% or 18.6%. VAT at 23% is worked out last, on customs value with duty and excise added.

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

Zero-duty paperwork — our job

You put nothing together yourself. We check the origin of the car by VIN, prepare the papers and run the clearance; if the production data points to assembly outside the USA, we declare it at 10% so the bill does not change when you come to collect.

What to watch for when buying at auction

Before you raise your bid, look at the damaged area. On a Century 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?

The comparison only means something after a VIN check. The same Buick Century bought in the States can come in at 0% or 10% depending on the assembly plant, so a car from the USA is not one cost category. On the European side clearance falls away, and usually so does the choice of versions.
