The GLC was supposed to be Alabama’s next big job. Mercedes has now moved the start of Tuscaloosa production from late 2027 to 2030 [link: Mercedes confirmation]. That leaves one of its highest-volume U.S. models on boats from Germany, paying import duty at every port of entry, for more than two extra years.
What Mercedes promised in the spring
In March, the Alabama Department of Commerce announced that Mercedes would put $4 billion into its Tuscaloosa County plant by 2030. Mercedes-Benz U.S. International employs about 5,800 people and exports around 60% of what it builds. The GLC, the state said, was “headed to the Tuscaloosa County assembly lines in the next few years.” That wording was vague enough to cover a delay like this one.
The plant currently builds the GLE, GLE Coupe, GLS, the AMG versions, the Maybach GLS, and the EQE SUV and EQS SUV. Adding the GLC was meant to fill capacity and avoid the tariff in one move.
Why the GLC matters this much
Mercedes won’t hand over a GLC unit count. It leaves hints. In the Q3 2026 release, MBUSA called the GLC and GLE “key pillars” of the lineup and said the GLC posted gains for the year so far. Mercedes sold 221,200 passenger cars in the U.S. through September, down 1%.

The Q1 release is more revealing: the GLC, GLE and GLS together accounted for 61% of passenger-car retail sales. The GLE and GLS are already built in Alabama. The GLC is the one in that group still coming from Germany. GLC sales also rose 20% in calendar 2025. So the model most exposed to tariffs is also one Mercedes depends on most.
How the 15% actually hits
Fifteen percent sounds simple. It isn’t. Under the Commerce Department and USTR Federal Register notice implementing the U.S.-EU framework, EU-built passenger cars face a combined duty of 15%. That figure replaces both the old most-favored-nation rate and the Section 232 auto tariff, so the two don’t stack.
Two catches.
- The duty applies to the import value, not the sticker price. Customs taxes what Mercedes USA pays the factory, which is well below MSRP. Our example: on a GLC with a $40,000 customs value, the duty is $6,000 per vehicle. Multiply that by every GLC that crosses the Atlantic and the bill climbs fast.
- Building in Alabama doesn’t make the tariff disappear. The same notice sets a 15% rate for EU-made auto parts. A U.S.-assembled GLC would still pay duty on any engines, transmissions or electronics shipped from Europe. Moving assembly reduces the bill but doesn’t eliminate it.
Why wait? Our read
Mercedes hasn’t given a public reason in its own materials. The timing points to the model cycle. The current GLC is already several years old. Setting up a body shop, paint line and supplier network for a vehicle that will be replaced soon after production starts means paying for tooling twice. Wait for the next generation and Alabama tools up once.

Every GLC sold in the U.S. between now and the 2030 start pays the 15% duty. Mercedes either raises prices or eats it. One more possibility, and it’s speculation: trade terms that were renegotiated once can be renegotiated again, and a lower EU rate before 2030 would make waiting look smart.
What it means if you’re shopping for a GLC
- Prices: A German-built GLC costs Mercedes more to land here than it did before the 2025 tariffs. Don’t count on deep discounts or fat lease deals the way you might on an Alabama-built GLE.
- Parts and repairs: Collision and service parts for a German-built model also come through European supply chains. Parts subject to the EU parts rate can raise repair costs, and over time that can feed into insurance premiums on newer luxury crossovers.
- Buying timeline: If you’ve been waiting for a “Made in USA” GLC hoping it will cost less, you’ll be waiting until at least 2030, and you’ll be buying a new generation, not the current model.
- Electric GLC: Mercedes says global sales of the new electric GLC more than tripled from Q2 to Q3. That’s a separate model on a different timeline, and this delay doesn’t change when you can buy one.
Would you pay the German-import price now, or hold out and bet the tariff gets renegotiated before 2030?
