Tariff Shock: How Construction Material Costs Will Shift in Q2 2026

The Policy Shift

On March 3, 2026, the administration announced a new round of tariffs targeting imported construction materials from China, Vietnam, and Brazil. Steel tariffs are jumping from 7.5% to 25%. Aluminum follows at 20%. And there's a new 15% duty on engineered wood products that caught the entire lumber industry off guard.

These aren't gradual phase-ins. They take effect April 15. That gives builders, developers, and procurement teams roughly 6 weeks to adjust strategies. We spoke to 8 industry insiders to map out what happens next.

Steel and Aluminum: First Impact Zone

Domestic steel producers are already signaling price increases of 12-18% by May. The market was tight before the tariff announcement. Now it's going to get tighter.

"We've already seen spot prices move 8% in two weeks. The full impact hasn't even hit yet. If you're bidding projects right now, you need to build in a 20% material cost buffer or you're going to lose money." - Sarah Torres, National Steel Supply Association

The aluminum story is similar but with an additional wrinkle: 40% of specialty aluminum products used in commercial construction come from a single region in China that's now subject to the highest tariff tier. There's no domestic substitute at scale. Lead times will extend from 6 weeks to 14 weeks minimum.

Lumber: The Indirect Squeeze

The 15% duty on engineered wood products is the surprise that's going to cause the most operational disruption. Cross-laminated timber (CLT), laminated veneer lumber (LVL), and glulam beams are increasingly used in mid-rise construction. 60% of CLT used in North America is imported.

Domestic CLT capacity can't fill the gap. There are only 4 CLT plants in the US, and they're already running at 85% capacity. The math doesn't work for a quick ramp-up.

  • CLT prices likely to increase 22-30% by June
  • Projects using mass timber should lock in supply contracts immediately
  • Developers may need to re-evaluate material choices for projects in early design phase
  • Insurance implications: some carriers are reassessing coverage terms for projects with extended material lead times

What Builders Should Do Now

The next 6 weeks are critical. Here's the playbook based on our conversations with procurement specialists and construction CFOs:

First, audit every active bid and project in pre-construction. Any material cost assumption made before March 3 is now wrong. Recalculate with 15-25% material buffers depending on steel/aluminum/wood exposure.

Second, accelerate purchase orders for any materials you can lock in at current prices. Pre-tariff inventory will sell out fast. If you have warehouse capacity, over-order now.

Third, open conversations with domestic suppliers you haven't used before. Relationships built in the next 30 days will determine who gets priority allocation when supply tightens further.

The Opportunity in the Chaos

Every disruption creates opportunity for operators who move first. Here's where the smart money is going:

Domestic steel producers will see margin expansion. If you're an investor, look at the mid-cap domestic steel ETFs. They're underpriced relative to the earnings bump coming in Q3.

Material brokers and logistics companies that specialize in construction supply chains will see massive demand. If you're an operator in this space, now is the time to expand capacity.

And for builders willing to explore alternative materials and construction methods, the tariff creates a forcing function for innovation. Modular construction, 3D-printed components, and recycled steel are all going to get a second look from developers who previously dismissed them as too experimental.

Frequently Asked Questions.

When do the new tariffs take effect?
April 15, 2026. Steel tariffs increase to 25%, aluminum to 20%, and a new 15% duty applies to engineered wood products from China, Vietnam, and Brazil.
How much will construction costs increase?
Based on our analysis, total construction costs for a typical commercial project will increase 6-10% due to material cost changes alone. Projects with heavy steel or CLT exposure could see higher impacts. Residential projects are less affected due to lower steel dependency.
Are there any exemptions or phase-in periods?
As of the March 3 announcement, there are no exemptions for construction materials. Industry groups are lobbying for a 90-day phase-in, but the administration has signaled these tariffs are firm. We'll update this analysis if the policy changes.
