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 Optima 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 Optima 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.

Kia Optima 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 Kia Optima 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 Kia Optima assembled?

Optima cars off American lines carry the VIN prefixes 5XX 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.

Plant	Country	VIN prefix	Cars in our database	Duty
—	United States	5XX	49,111	0% duty
Hwasung	South Korea	KNA	13,635	10%
Whasung	South Korea	KNA	938	10%

Made in USA • Tax 0%

How do you check a specific car?

The VIN settles the matter in seconds. Optima cars from plants in the USA carry the prefixes 5XX 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 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 Optima 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

Three tax lines and one variable. Duty follows the assembly country of your Optima: 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.

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 Optima 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 Optima 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.

Damage	Cars in our database
Front end	23,380
Rear end	7,251
Side	5,501

From the USA or from Europe?

The comparison only means something after a VIN check. The same Kia Optima 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.
