Is a VIN prefix enough to establish the rate?

No. The first three characters point to the manufacturer and the country, but one prefix can cover several plants. The rate needs the country of final assembly tied to the full number, and that is exactly the reading you get after entering a VIN.

What if the Sierra 2500 came off a line in Canada?

Then the car does not use the preference and enters the EU at 10% duty. Canada and Mexico are the most common source of confusion, because cars from there reach sales in the States on equal terms with cars of American production.

Does zero duty also lower VAT?

Indirectly. VAT at 23% is charged on customs value with duty added, so 0% instead of 10% shrinks the tax base. Excise is worked out separately by engine size and comes to 3.1% or 18.6% either way.

Since when has the customs preference applied?

Since 2026-07-01, under the EU–US Agreement on Reciprocal Trade. It covers passenger cars finally assembled in the United States. Cars from plants in other countries keep clearing at 10%, whatever the market they were bought on and whoever sold them.

Does the model year change the assembly country?

Sometimes it does. Manufacturers move production between plants partway through a generation, so a Sierra 2500 from two different model years can carry a different assembly country. That is why the rate is set for a VIN and not for a model name.

GMC Sierra 2500: where the car was built and what it pays

Zero duty is a property of one car, not of the GMC Sierra 2500 as such. An American line means 0% duty and a lower 23% VAT base; a line outside the States means 10%. Manufacturers run parallel production on several continents, so two cars from one model year can clear differently.

Where is the GMC Sierra 2500 assembled?

Production of the GMC Sierra 2500 is often spread across continents, which is why the question of where it is built has several answers at once. For duty, only the country of the plant your car came off matters: the States mean 0%, any other country 10%. Model history and target market change nothing.

How do you check a specific car?

The quickest filter is the first three characters of the number — on a Sierra 2500 with American assembly that is usually 1GC. 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 zero rate works in two places at once: 10% of duty disappears and the base for 23% VAT falls with it. That is why the difference across the whole bill on a US-assembled Sierra 2500 is larger than duty alone. The result follows customs value, so put yours into the calculator.

Work out the import cost

What the import cost is made of

The structure is the same for every car and only the first line differs. A Sierra 2500 off an American line comes in at 0% duty, a car outside the preference at 10%; after that comes excise by engine size (3.1% or 18.6%) and 23% VAT. Customs value follows the hammer price and transport.

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

Proof of origin and clearance are on us. For a Sierra 2500 that the VIN places on an American line, we assemble the plant documentation and declare the car at the 0% rate. What we need from you is the car you picked and its VIN.

What to watch for when buying at auction

An auction description talks about damage, not about origin, and the other way round. A Sierra 2500 with a wrecked front can be assembled in the USA and come in at 0%, while an untouched car from the same sale comes from Mexico and pays 10%. Check both separately.

Side	75

From the USA or from Europe?

The difference comes down to what you add and what you get back. Buying a Sierra 2500 in Europe, you skip the ocean crossing and the clearance; buying in the States you add both, but on a car from an American line duty is 0% instead of 10%. Your choice depends on how much paperwork and repair you take on.
