Caterpillar's Q1 2026 tariff bill was expected to land at $800 million before a single excavator shipped.
The company is running record backlogs on data center and infrastructure equipment, with demand as strong as it's ever been.
Its adjusted operating margins are still getting pushed toward the bottom of their target range because the input cost structure shifted underneath a business that changed nothing about how it operates.
👋🏻 I'm Leonardo Ubbiali. This week we're looking at why what's happening to Caterpillar is happening to manufacturers everywhere, and why supply chain AI is becoming the only lever that moves the cost line.
Section 232 tariffs on steel and aluminum hit 50% in June 2025, up from 25%. Hydraulic cylinders, transmission systems, and high-strength steel frames sourced from China face additional Section 301 duties on top of that.
US Hot-Rolled Coil steel now trades at $950 to $1,050 per short ton. Chinese mills are selling the same product at roughly $460.
50% of Caterpillar's Q1 2026 tariff exposure falls on Construction Industries, 30% on Energy and Transportation, and 20% on Resource Industries.
The machines selling fastest into the data center boom are carrying the heaviest import cost.
CEO Joseph Creed said the company is making limited dual-sourcing moves "where it's beneficial" and certifying products under USMCA to shift some flows.
On bigger decisions: "we intend to implement longer-term actions once there is sufficient certainty."
That's the constraint.
In 2025, Caterpillar faced $1.8 billion in gross tariff costs and managed to offset only around $100 million of it through actions that directly reduced what they paid.
Bonfield said that without the mitigation actions planned for 2026, the $2.6 billion bill would be around 20% higher.
You can't move a factory in six months, and committing to a new supplier network while tariff policy is still being litigated in the Supreme Court is a bet most CFOs won't approve.
64% of manufacturers have no plans to reshore. The other 36% are considering it, but not doing it.
Caterpillar is a good example of why. An excavator's hydraulic system contains precision-machined components and specialized alloys with no viable domestic alternative at the volumes they need.
A tariff doesn't create that supplier. It makes the existing one more expensive.
86% of manufacturers plan to pass at least some cost increases to customers.
Raw material prices are projected to rise another 4.4% in 2026.
What moves the cost line
Caterpillar is doing what's available: dual-sourcing where there's an alternative, USMCA certification where flows allow, holding bigger restructuring decisions until policy stabilizes.
But all of that takes months to set up, and tariff announcements don't wait.
The same problem applies to sourcing decisions.
The analysis a category manager needs takes days to pull together manually. By then, the window to act has usually narrowed.
The same logic applies to sourcing.
A system monitoring tariff exposure across a full bill of materials can flag when a component's landed cost crosses a threshold and surface pre-qualified alternatives before a category manager opens a spreadsheet.
Caterpillar is waiting for policy certainty before it makes its longer-term moves.
An AI system surfaces the decision the moment the numbers change.
The team is ready to act instead of starting the analysis.
70.6% of manufacturers cite trade uncertainty as their top concern.
The manufacturers absorbing this quarter's tariff hit started their exposure analysis after the announcement and the ones who will absorb less next quarter started before it.
Five things you can do this quarter
The problem: Your CFO wants to understand tariff exposure if rates increase another 10% in Q3. You don't have a clean answer ready.
The Prompt (copy this):
I'm a [YOUR ROLE] at a [PRODUCT TYPE] manufacturer. I need to build a tariff exposure model to present to our CFO by [DATE].
Top three product lines: [LIST] Primary imported materials and components: [LIST WITH COUNTRIES OF ORIGIN] Current tariff rates affecting us: [LIST]
For each major input:
Calculate total annual cost impact at current tariff rates
Model what happens if tariffs increase 10%, 20%, and 30%
Identify which components have qualified domestic or low-tariff alternatives
Flag which have no viable alternative at any price point
Then give me the top five decisions I should make now, before the next tariff change.
What you'll get back:
A working exposure model with decision triggers, so you can answer the CFO's question and be ready to act when policy shifts.

Caterpillar will absorb whatever Q2 brings and start planning for Q3. What does your tariff exposure look like going into Q2, and do you know the answer right now?
Hit reply. I read every email.
