Introduction: Tariffs, Material Costs, and the 2026 Reality for Carolinas Contractors
The construction industry across North and South Carolina is facing a stark financial reality in early 2026. According to analysis from Associated Builders and Contractors using Bureau of Labor Statistics data, nonresidential construction input prices rose at a 7.1% annualized rate in January 2026—a blistering pace driven by tariff-affected materials like structural steel, aluminum, and copper wire.
This article is designed for Carolinas commercial contractors, project managers, and construction business owners who need to understand how 2026 tariff costs directly impact their financial planning and project success. Staying informed about tariff-driven material costs is critical for maintaining profitability, managing risk, and ensuring project viability in a volatile market.
Recent analyses by the ABC chief economist and the AGC chief economist highlight how tariffs have significantly influenced construction material costs in 2026, providing authoritative insights into market trends and the broader impact on construction expenses. Contractors’ analysis shows that many firms are closely evaluating how tariffs affect project budgets and overall cost management. Notably, the earlier part of the recent period saw the sharpest increases in material prices due to tariff changes, followed by some stabilization.
Many ABC Carolinas members report at least one commercial or industrial project in the past year that was cancelled, rebid, or significantly scaled back after updated steel, aluminum, or switchgear quotes exceeded original budgets by 10-15%. This article focuses on financial and contractual strategies—escalation clauses, tariff-specific provisions, early procurement, alternative materials—that protect your margins rather than simply reporting price increases.
Key Definitions: Tariffs and Affected Materials
Tariff: A government-imposed tax on imported goods, designed to protect domestic industries or respond to trade disputes.
Section 232 Tariffs: U.S. federal tariffs applied to imported steel and aluminum for national security reasons. In 2025 and 2026, these tariffs expanded significantly, reaching up to 50% on many steel and aluminum products.
Most Affected Materials: Steel, aluminum, and copper products are among the materials most affected by tariffs in the construction industry. As of 2026, steel and aluminum face tariffs up to 50%, and copper products are subject to a 50% tariff.
National Context: 2026 Construction Material Tariffs
The 2026 construction material tariff environment is shaped by several major federal policies and global trade dynamics:
- Section 232 Tariffs Expansion: The federal government’s use of Section 232 tariffs on imported steel and aluminum expanded significantly in 2025 and into 2026, with rates reaching as high as 50% on many products.
- 10% Global Tariff and 50% Copper Tariff: A 10% global, time-limited tariff is in effect until July 2026, alongside a 50% tariff on copper products and derivatives.
- Concentration on Key Trading Partners: By early 2026, high tariff costs on construction materials will be concentrated on imports from China, Mexico, and Canada, with an effective tariff rate between 25% and 30%.
- Impact on Project Costs: These tariffs are driving up material costs, leading to a 4–6% increase in overall project expenses for U.S. construction firms.
Understanding this national context is essential for contractors in the Carolinas as they adapt their budgeting, procurement, and delivery strategies to manage the cost environment effectively.
The 2026 Tariff and Cost Landscape: What’s Driving Construction Material Prices
Current tariffs and trade policy are reshaping construction costs across the Carolinas:
- Steel and aluminum tariffs reached 50% as of June 2025.
- Copper products followed with a 50% tariff in August 2025.
- Structural steel, rebar, metal deck, and aluminum framing have seen the steepest price increases.
- Industrial controls, equipment, and switchgear continue to experience double-digit increases.
- Fabricated products (joists, metal panels, RTU housings) pass these tariff costs on to commercial, healthcare, manufacturing, and higher-ed projects.
Federal officials are being urged to renew key infrastructure measures, such as the surface transportation bill, to provide the certainty needed for domestic suppliers to boost production and help offset the upward pressure on construction material costs.
Owners in Charlotte, Raleigh, Greenville, Charleston, and the Triad are increasingly delaying NTPs, rebidding scopes, or value-engineering structural and MEP systems due to tariff-driven quotes. While energy prices remain tame, input prices for metals and electrical components remain elevated, creating a mismatch between owner expectations and contractor pricing.
How Tariff-Driven Costs Hit Project Budgets and Margins in the Carolinas
On a typical commercial project in the Carolinas:
- Metals and controls can represent 20-30% of hard costs.
- A 10-15% swing in these categories can add 3-5% to total project costs—often more than the contractor’s entire profit margin.
- Nonresidential input prices and costs have experienced significant escalation pressure due to tariffs.
- The gap between budget-phase assumptions (2024-2025 pricing) and actual procurement-phase quotes (late 2025 and early 2026) erodes fee and contingency rapidly.
- Absorbing tariff-driven increases stretches working capital, adds unpriced risk, and weakens your ability to invest in safety, workforce development, and equipment.
- The sustainable response is to move tariff risk into contracts, procurement strategy, and owner communication—not into your balance sheet.
- Some categories have remained virtually flat, with demand subdued in certain market segments.
Using Price Escalation Clauses to Share Tariff Risk
Traditional lump-sum contracts are risky in a tariff-heavy environment, especially for metal-intensive scopes. Price escalation clauses adjust the contract price if certain material costs rise beyond defined thresholds after the bid date.
Key recommendations:
- Tie escalation to objective third-party indexes (e.g., BLS Producer Price Index for steel, aluminum, copper).
- Set triggers at 5-10% price movements between bid submission and purchase order date.
- Focus escalation on tariff-sensitive categories: steel, aluminum, copper wire, and industrial controls.
- Maintain transparent documentation: dated supplier quotes and contemporaneous records.
ABC Carolinas provides members with sample escalation clause language and educational sessions on risk shifting through its committees focused on contracts, safety, and education.
Tariff-Specific Contract Provisions: Naming the Risk Directly
In 2026, many contractors in the Carolinas are moving beyond generic escalation language to clauses that specifically reference tariffs and government-imposed duties.
Essential elements:
- Define “tariff event” and affected materials.
- Specify mechanisms for cost recovery: change orders, unit price adjustments, or shared-cost formulas.
- Integrate with force majeure and changes-in-law provisions.
- Coordinate with attorneys and surety partners for bondability.
ABC Carolinas offers legal education programs and contract language tools to craft enforceable tariff clauses, backed by its national advocacy efforts that protect merit shop contractors.
Early Procurement and Material Lock-In Strategies
Buyout timing is critical in 2026. Early procurement tactics include:
- Pre-purchasing structural steel or major electrical gear once the contract award is likely.
- Negotiating early-release packages with owners and design teams.
- Using letters of intent to lock supplier pricing before design completion.
- Building internal purchasing calendars and approval workflows.
This approach requires increased working capital and storage considerations but secures fabrication slots and reduces critical-path delays. ABC Carolinas networking and educational events help members build relationships with mills and distributors offering forward-pricing arrangements.
Strengthening Supplier Relationships in a Tariff-Driven Market
In 2026, supply reliability and risk-sharing are as important as price. Construction firms should:
- Build longer-term agreements with steel fabricators and electrical suppliers.
- Hold periodic strategy meetings to review upcoming projects and tariff movements.
- Design pricing mechanisms like quarterly resets or indexed adjustments.
- Maintain at least two qualified suppliers for critical scopes.
ABC Carolinas serves as a connector through chapter meetings, trade shows, member roundtables, and safety summits focused on supply chain risk.
Evaluating Alternative Materials and Construction Methods
New tariffs on imported metals and materials are pushing owners and general contractors to explore alternatives. While metals have seen significant tariff impacts, commodities like softwood lumber have experienced only modest gains or dips, making them a less volatile alternative:
- Structural alternatives: Use concrete systems, engineered wood (where code allows), domestically produced metal systems, or softwood lumber.
- Panelized systems: Structural insulated panels (SIPs) and insulated metal panels reduce steel tonnage and labor hours.
- Modular construction: Factory environments enable bulk material purchases and more predictable cost control.
Contractors should proactively bring VE options to owners before DD or 50% CDs. ABC Carolinas’ education programs, apprenticeships, and craft education initiatives highlight successful Carolinas projects using these approaches.
Communicating Cost Increases to Owners and Developers Without Losing the Bid
The tension in 2026 is real: owners want fixed prices based on pre-2025 expectations while contractors face real-time volatility. Effective communication strategies include:
- Present bids with transparent line items for tariff-exposed scopes.
- Include clearly explained escalation provisions with simple examples.
- Offer options: a lower base price with an escalation clause, or a higher “locked” price.
- Use visual tools—ENR or BLS graphs, regional price history—to build understanding.
Frame these conversations around project viability, not contractor protection. ABC Carolinas provides members with talking points, market briefings, and expert construction safety training resources.
Risk Management, Not Cost Absorption: The Contractors Who Will Survive 2026
Simply absorbing rising costs is unsustainable—especially for small and mid-sized construction firms. The key levers are:
- Smarter contracts with escalation and tariff clauses.
- Earlier procurement and material lock-in.
- Stronger supplier partnerships.
- Strategic use of alternative building materials and methods.
Financial resilience enables firms to continue investing in safety training, apprenticeship programs, and workforce development, including healthcare captive solutions that help stabilize benefit costs. ABC Carolinas serves as a strategic ally providing economic intelligence and advocacy.

Frequently Asked Questions
Which construction materials are most exposed to the 2026 tariffs in the Carolinas?
Structural steel, rebar, metal deck, aluminum storefront and curtain wall, metal roofing, copper wire and cable, industrial controls, switchgear, and certain HVAC equipment housings are most exposed. Even domestically produced items often rise because domestic suppliers follow tariff-driven increases in import prices.
How can smaller contractors compete when they lack the buying power of larger firms?
- Focus on strong supplier relationships.
- Join buying groups or team with larger GCs for certain packages.
- Use well-drafted escalation clauses to prevent absorption of price spikes.
- Leverage associations like ABC Carolinas for market intelligence, contract tools, introductions to reliable regional suppliers, and direct support via the ABC Carolinas contact team.
Are owners in the Carolinas actually accepting escalation and tariff clauses in 2026?
- Acceptance varies by owner type.
- Institutional and repeat private developers are more likely to engage in risk-sharing.
- As more projects face rebids or delays due to blown material budgets, owners increasingly accept clearly defined, narrowly scoped provisions when supported by data.
What if tariffs go down—do escalation clauses only protect contractors?
- Well-drafted mechanisms can be symmetrical, adjusting prices up or down based on independent indices.
- Balanced clauses build trust with owners and position contractors as long-term partners.
How can my firm start implementing these strategies without overwhelming our team?
- Start with two or three changes: add a tariff/escalation addendum to standard subcontracts, hold quarterly pricing reviews with key suppliers, and pilot early procurement on one major project.
- ABC Carolinas workshops, peer roundtables, and EIC program events offer practical, step-by-step guidance.
