What Does a 25% Tariff Mean for Your Construction Budget?

Material costs could increase 10-25% on imported steel, aluminum, and lumber due to tariffs—potentially cutting contractor margins in half unless contracts include protective language.

What Does a 25% Tariff Mean for Your Construction Budget?

A 25% tariff on imported steel and aluminum has direct, measurable consequences for every contractor managing material-intensive projects.

Understanding the Math

On a $300,000 commercial project with $90,000 in steel and aluminum components, a 25% tariff adds $22,500 to your material costs. If your original profit margin was $45,000 (15%), that tariff just cut your profit in half.

How to Calculate Your Exposure

  1. Identify all imported material categories in your scope
  2. Determine the tariff percentage applicable to each category
  3. Apply the tariff increase to your estimated material costs
  4. Compare the resulting total against your profit margin

Protective Strategies

  • Include material escalation clauses with specific tariff language
  • Request longer price-lock periods from suppliers
  • Build tiered contingencies based on material risk categories
  • Consider domestic sourcing alternatives where cost-effective
  • Shorten bid validity windows to 30 days

The Bottom Line

A 25% tariff does not have to mean a 25% hit to your budget—but only if you have systems to track, plan, and protect your margins in real time.
