Breaking: Steel, Wood Tariffs Trigger 40% Material Cost Increase

The construction industry faces a dramatic material cost increase as new steel and wood tariffs send shockwaves through the market. Building material costs have jumped 34% since December 2020. Industry experts predict current tariff rates will push construction material costs up by 9% compared to 2024's average costs. These changes will drive total project costs up by 4.6%, creating major hurdles for builders and consumers.

Recent construction industry trends highlight serious concerns about America's supply chain weakness. The residential construction sector used $204 billion worth of goods in 2024, with $14 billion coming from foreign sources. This means foreign nations supply 7% of all materials used in new home construction. Builders report these recent tariffs add $10,900 to each home's cost. Steel prices show the most dramatic increases. Four major rebar manufacturers raised their prices by $60/ton in June 2025. Construction-grade steel's average per-ton cost has surged more than 20% this year. Softwood lumber prices have decreased 4.8% this month, yet remain 12.2% higher than last year . These changes continue to drive raw material costs higher across the construction sector.

Tariffs Trigger Sudden 40% Spike in Material Costs

The construction sector struggles as new tariff policies have caused material costs to jump 40.5% since February 2020 ^[1]. This sharp increase represents the biggest yearly rise in construction input prices since early 2023.

Steel and wood prices surge across U.S. markets

Federal tariffs on steel and aluminum imports doubled to 50% in June 2024 ^[2]. Copper faced similar 50% tariffs starting August 2024 ^[2]. These changes hit the market hard - aluminum mill shapes saw a 5.5% increase last month and soared 22.8% over 12 months ^[2]. Steel mill products rose 1.5% in August and 13.1% year-on-year ^[2]. This allowed domestic producers to raise their selling prices ^[3]. Canadian lumber duties will jump from 14.5% to 34.5% ^[4]. This adds pressure since Canada supplies about 85% of all U.S. softwood lumber imports ^[4].

Builders report immediate cost overruns on active projects

Recent industry surveys show 43% of contractors have seen projects canceled, delayed, or reduced due to rising costs ^[2]. Two in five firms now charge more ^[2]. Many buy materials early to avoid future price increases ^[2], while 16% split costs with suppliers or absorb them ^[2]. Contractors can't get fixed subcontractor prices beyond 45 days ^[2]. This leads them to adjust schedules, use rolling scopes, and increase contingency allowances ^[2].

NAHB and ASCC confirm widespread impact on housing affordability

The National Association of Home Builders (NAHB) states these tariffs act as a "tax on American builders, home buyers and consumers" ^[5]. Market uncertainty and inflation keep driving housing costs up ^[5]. Domestic production can't match imported volumes without charging more ^[2]. The U.S. imports about 30% of its softwood lumber ^[2]. This highlights why tracking industry import trends matters. Builders now use pricing tools for quick updates and systems that help adjust prices as markets change.

Ken Simonson, AGC chief economist, explains that "Higher trade tariffs imposed on imports have enabled domestic producers to push up their selling prices" ^[2]. About 40% of contractors expect prices to rise in coming months ^[2]. This underscores their ongoing challenges.

How Do Tariffs on Steel and Wood Work?

Tariffs act as taxes on imported goods, and importers must pay extra costs to bring products from foreign countries into the United States ^[2]. The construction industry has felt the effects of these import duties, which have disrupted the supply of essential building materials.

Tariffs explained: import taxes and their economic intent

Tariffs play several economic roles - they protect domestic industries from overseas competition and help generate government revenue. A retailer who imports a $500 washing machine with a 25% tariff pays $125 to the U.S. government ^[2]. Importers then have several options:

• Negotiate with the exporting country to absorb some costs
• Reduce their profit margins
• Increase prices for consumers
• Use some combination of these strategies ^[2]

U.S. construction import tariff rates have jumped to 27.7%, compared to 19.2% in May and just 0.9% before policy changes ^[6]. This fundamental change sends immediate shockwaves through supply chains.

Why steel and lumber are targeted under Section 232

Section 232 of the Trade Expansion Act of 1962 lets the President limit imports that could threaten national security ^[7]. This authority, once used mainly for metals, now covers wood products due to concerns about domestic industry's vulnerability ^[7]. The White House defends these measures as needed "to protect against threats to the U.S.'s national security and to strengthen manufacturing" ^[8].

The Commerce Department's investigation found that wood products are vital for national defense, supporting military infrastructure and key sectors like communications, energy, and transportation ^[9]. These tariffs help counter foreign subsidies that weaken domestic competition ^[10].

How importers pass costs to builders and consumers

These expenses flow down the chain - from importers to distributors, contractors, and eventually to consumers through higher home prices ^[2]. The National Association of Home Builders (NAHB) points out that "consumers end up paying for the tariffs in the form of higher home prices" ^[2].

Builders need responsive pricing systems to handle these changes. Smart strategies include up-to-the-minute pricing tools, flexible contract clauses, stored material payment negotiations, and diverse supplier networks ^[11]. As markets change, systems that allow quick price adjustments - from single changes to complete updates through export-reimport processes - become crucial for project success.

Steel and Wood Tariffs Disrupt Construction Supply Chains

Recent tariff expansions have created chaos in construction supply chains. The industry must adapt as material prices continue to rise.

Canadian lumber tariffs rise to 34.5%

The Department of Commerce's regulatory review has pushed Canadian softwood lumber duties from 14.5% to 34.5% ^[4]. Canada supplies about 85% of U.S. softwood lumber imports and nearly a quarter of America's total supply ^[12]. These changes create major challenges for framing, millwork, and cabinet fabrication ^[13]. The new duties could add more than $9,000 to new home prices ^[14]. This increase will affect residential construction projects that are still in their planning phases.

Steel import tariffs reach 50% under new policy

Steel and aluminum tariffs doubled to 50% on June 4, 2025 ^[15]. The policy now includes 407 more product categories ^[16]. The expanded list covers fire extinguishers, auto parts, construction materials, and specialty chemicals ^[17]. These changes have pushed the tariff's effect on imports from $190 billion to at least $320 billion ^[17].

Formwork, rebar, and aluminum components face delays

Material availability has become a serious concern. The shortages of rebar, structural steel, and aluminum components ^[5] remind us of pandemic-era supply problems. Tariff-related costs have forced almost 25% of contractors to delay or cancel their projects ^[18]. Companies try to alleviate risks through warehouse storage strategies and early procurement packages ^[5].

Industry import trends show change toward domestic sourcing

The industry's procurement strategies are changing faster than ever. Builders now add material escalation clauses to protect themselves from tariff-driven price swings ^[13]. Some companies broaden their supplier base, look into alternatives like mass timber ^[5], or use systems for quick price adjustments during market changes ^[19]. In spite of that, America's workforce limitations make it impossible to replace imported construction materials quickly ^[5].

How Can Builders Adapt to the Raw Material Cost Increase?

Builders must adapt their strategies to handle material costs that remain 39.7% higher than pre-pandemic levels due to rising tariffs ^[20].

Use pricing tools that allow real-time updates

Modern construction management software links material catalogs and labor estimates to local market conditions ^[21]. Builders who use real-time cost tracking experience 30% fewer material-related delays ^[1] and reduce project overruns by 20% ^[1]. These digital tools help contractors monitor price changes, access cost databases, and compare ongoing expenses with budgets ^[1].

Quote proactively with flexible contract clauses

Smart builders add price escalation provisions that address tariffs directly ^[22]. Their contracts include language about schedule adjustments, material substitutions, and scope revisions ^[23]. Time and materials (T&M) contracts have proven valuable because they let builders adjust billing based on actual costs throughout the project ^[24]. This approach reduces time investments and project expenses ^[24].

Negotiate stored material payments and change orders

About 16% of companies share costs with suppliers or absorb them completely ^[3]. Teams can reduce supply disruptions through early procurement packages and stored material payments ^[3]. Change order management has become crucial since 43% of contractors face project cancelations or delays due to rising costs ^[3].

Export, update, and reimport prices to reflect market shifts

Software that allows price refreshes helps builders avoid quoting outdated figures when material costs spike overnight ^[21]. Systems with bulk price update capabilities through export-reimport functions keep estimates accurate up to 30 days after the original quotes ^[21].

Vary suppliers and explore alternative materials

Material costs have jumped 40%, making alternative material substitution provisions crucial ^[22]. Contractors can suggest substitutes that maintain quality standards when prices cross certain thresholds ^[22]. The analytics features help teams learn about spending patterns and find affordable sourcing options. One contractor saved 10% on drywall costs each year by changing suppliers ^[1].

Conclusion

Construction companies now face their biggest challenges ever. Tariffs have pushed material costs 40% above pre-pandemic levels. Steel and wood prices have shot up, and these costs get passed down to consumers just like taxes.

Trade policies make the industry vulnerable. American builders feel the pain when 7% of residential construction materials come from overseas. Canadian lumber duties have jumped to 34.5%, which hits particularly hard because domestic producers can't match these volumes without raising prices.

Builders need technology and flexible contracts to stay ahead. Immediate pricing tools help track changing markets, and quick-update systems prevent outdated quotes. Contract clauses that deal with tariffs protect everyone from sudden price changes.

Working with different suppliers has become vital as materials become scarce. Buying early and paying to store materials helps reduce supply problems, but this needs careful money management. Looking at alternative materials is another way to keep projects viable despite rising costs.

These tariff challenges will stick around through 2025. Builders who create detailed strategies to adapt will pull ahead of competitors. Knowing how to adjust prices quickly—through single changes or complete updates—is vital to stay profitable.

The construction industry has reached a turning point. While tariffs create obstacles, they push companies to improve their practices. Companies that become skilled at responsive pricing, develop adaptable contracts, and keep good relationships with many suppliers will do well despite higher material costs. Success in this unpredictable market needs alertness, flexibility, and smart planning.
