The US placed a 25 percent tariff on imported medium and heavy duty trucks starting November 1, 2025, and it remains in effect. New truck prices on affected models rose by tens of thousands of dollars, which pushed buyers into the used market and lifted used prices too. Vehicles built under USMCA rules now face the tariff only on their non US content.
- The 25 percent Section 232 tariff covers Class 3 to Class 8 trucks and took effect November 1, 2025.
- Only about 8 percent of the Class 8 market pays the full tariff, but analysts estimate affected new tractors jumped from around 175,000 to around 250,000 dollars.
- Since February 2026, USMCA qualifying vehicles are taxed only on non US content, which softened the blow for compliant builds.
- Steel, aluminum, and copper duties at 50 percent are raising parts and upfit costs on top of the truck tariff.
If you priced a new heavy duty truck lately and felt your stomach drop, it is not just inflation. A 25 percent tariff landed on imported trucks and the market is still digesting it. Here is what happened, who it hits, and what it means if you are shopping.
What the tariff is
In late 2025 the US government imposed a 25 percent tariff on imported medium and heavy duty trucks under Section 232 of the Trade Expansion Act, citing national security. It covers Class 3 through Class 8 vehicles, which means everything from heavy duty pickups to delivery trucks to full Class 8 highway tractors. It took effect November 1, 2025 after a short delay, and as of this writing it is still in place.
The stated goal was to protect American truck manufacturing. The top exporters of these vehicles to the US are Mexico, Japan, Germany, Canada, and Finland, with Mexico alone accounting for the bulk of heavy truck imports.
Who actually pays it
Here is the nuance most headlines skip. Not every imported truck pays the full 25 percent on its full value.
Since February 2026, vehicles that qualify under the US Mexico Canada Agreement are taxed only on their non US content, not the whole vehicle. That change meaningfully reduced the hit on compliant builds. Analysts estimate only about 8 percent of the Class 8 market ends up carrying the full tariff, which is how an average new tractor price moved from around 175,000 dollars toward 250,000 dollars on the exposed slice rather than across the board.
There is also a 3.75 percent credit for manufacturers assembling medium and heavy duty vehicles in the US, running through 2030, meant to soften the blow of the parts tariffs.
The parts problem nobody talks about
The truck tariff is only half the story. Steel, aluminum, and copper duties sit at 50 percent, and those hit components. Bumpers, bodies, upfit equipment, and replacement parts all cost more to make. So even a truck assembled in the US with the assembly credit can carry higher costs from its imported parts content. When your replacement bumper costs 20 percent more than it did two years ago, this is why.
What it means for buyers
New trucks cost more. On affected models the increase is tens of thousands of dollars. Even unaffected models feel the pull as overall market pricing shifts upward.
The used market is hot. Fleets and private buyers priced out of new are buying used, which lifts used prices and moves good trucks fast. If you are selling a clean diesel, this is your market. If you are buying used, move decisively on the right truck and get an independent inspection every time.
Keep your current truck longer. With new prices where they are, the math on maintaining your existing truck looks better than ever. A 5,000 dollar repair on a truck you own beats a 90,000 dollar new truck payment all day. This is the market telling you to do your maintenance.
Should you buy now or wait
People ask me this constantly, so here is my honest answer. If you need a truck for work, buy the truck. Waiting for tariff policy to reverse has been a losing bet for over a year. Every policy change so far has rearranged who pays, not removed the cost. The February 2026 USMCA adjustment helped compliant builds, but nothing on the horizon suggests pricing will return to where it was before the tariffs.
If you do not need a truck urgently, the used market rewards patience differently. Watch for fleet turnover cycles. When large fleets finally cycle trucks they have been holding, clean high mileage units hit the market in waves. Those are often the best buys. Set up alerts, know your target models, and be ready to move with cash and a mechanic lined up to inspect it.
The Canadian angle
Canada is one of the top exporters of medium and heavy duty vehicles to the US, so Canadian built trucks bound for American buyers sit squarely in this fight. For Canadian shoppers, the direct tariff is American policy, but the effects cross the border. Cross border shopping got more complicated, parts cost more on both sides from the metals duties, and the North American used market moves as one. A hot used market in Texas lifts asking prices in Alberta too.
Bottom line
Buy used, buy on condition, and maintain what you have. The tariff era rewards the owner who keeps a truck for 400,000 km instead of trading at 150,000. That was always the smart play. Now the market agrees.
Frequently asked questions
Does the truck tariff affect pickup trucks or just semis?
It covers Class 3 through Class 8, which includes heavy duty pickups as well as delivery trucks, vocational trucks, and Class 8 tractors. Light duty half tons fall under separate auto tariff rules.
Should I buy a used diesel instead of new right now?
For most private buyers, yes. The tariff pushed fleet and private buyers toward used trucks, so used prices are strong, but a clean used diesel still costs far less than a new one carrying tariff inflated pricing. Get a pre purchase inspection and buy on maintenance history.
Will the tariff go away soon?
Nobody knows. The policy has already changed several times in a year, including the February 2026 shift to taxing only non US content on USMCA builds. Waiting for policy to settle has mostly cost buyers more in rising prices than it saved in timing.
