How Tariffs Will Impact US Aircraft Manufacturing

‍DALLAS — The aerospace industry is about to enter a period of significant change. 

Record global air travel demand has increased the need for commercial aircraft, yet U.S. manufacturers are struggling with production bottlenecks and supply chain disruptions. The White House's sweeping new tariffs have introduced additional cost pressures and trade uncertainties. 

This article examines the current state of U.S. aircraft parts imports, the industry's manufacturing challenges, and how the new tariffs further complicate the outlook.

Commercial Aircraft Parts Imports to the USA

A Concentrated Import Market

According to the Commercial Aircraft Parts Imports Outlook report, the United States hosts 1,821 aviation parts importers sourcing components from 412 global suppliers, with 875 importers active from March 2023 to February 2024. Within this ecosystem, the market is highly concentrated. For example:

• COLLINS AEROSPACE (B/E AEROSPACE) leads with a 23% market share and accounts for 733 shipments.
• BOEING COMMERCIAL AIRPLANES SEATAC follows with 14% (441 shipments).
• ITP EXTERNALS S L U holds 13% (399 shipments).

Collectively, these three companies represent nearly 50% of total US aviation parts imports, underscoring the market’s concentrated nature.

Navigating the Regulatory Turbulence

Importing aerospace components into the USA involves strict regulatory requirements. The Federal Aviation Administration (FAA) mandates that specific aircraft equipment undergo rigorous safety and quality approval before import. 

Additionally, importers must comply with duties and taxes based on the value of the goods, along with detailed customs documentation and inspections—all of which add complexity and cost to procurement.

Challenges in US Commercial Aircraft Manufacturing

Production Bottlenecks, Growing Backlog

The US commercial aircraft manufacturing sector has faced increasing production challenges since 2019. Despite a record delivery of over 1,800 aircraft in 2018, fewer than 1,300 aircraft were delivered by the end of 2024—a 30% drop during surging global air travel. 

This production shortfall has led to an unprecedented backlog of over 17,000 aircraft orders, with current rates indicating that it could take up to 14 years to clear the backlog.

Boeing’s Ongoing Struggles

Boeing, a linchpin of US aerospace manufacturing, has encountered multiple challenges. A notable safety incident in January 2024—when a door plug detached mid-flight—triggered FAA interventions such as groundings and production caps. 

Furthermore, labor disruptions, including a machinists' strike affecting three out of four production lines, have compounded these issues, with forecasts predicting a 38% decline in Boeing deliveries for 2024.

On April 2, 2025, Boeing CEO Kelly Ortberg appeared before the Senate Commerce Committee today to address concerns about the aerospace giant’s manufacturing and safety record following a series of crises

Under the purview of the Department of Transportation (DOT) and the FAA—and with the help of honest and unhindered employee input, the CEO stated that safety and quality plan actions have been taken in the following work areas:

1. Reducing defects
2. Enhancing employee training
3. Simplifying processes and procedures
4. Elevating safety and quality culture

Impact of New US Import Tariffs

Immediate Tariff Measures

On April 2, 2025, the US government declared a national emergency and imposed tariffs to address trade imbalances. The White House’s National Emergancy Fact Sheet outlines several key measures:

• A 10% baseline tariff on all imported goods, effective April 5, 2025.
• Effective April 9, 2025, major trade-deficit partners, such as India, will be subject to higher reciprocal tariffs of up to 26%.
• The reinstatement of aluminum and steel duties impacts essential materials for aircraft manufacturing.

Supply Chain Disruptions and Additional Cost Pressures

These new tariffs exacerbate preexisting supply chain challenges:

• Cross-Border Integration Risks: With NAFTA-era exemptions expiring, the flow of parts between the USA, Canada, and Mexico is now at risk.
  
  
• Increased Component Costs: Critical components—including electronics (representing 20–30% of aircraft costs), engines, and landing gear—face higher costs as tariff expenses cascade through the supply chain.
  
  
• Boeing’s Export Vulnerability: With 80% of its deliveries destined for overseas markets, Boeing is particularly exposed to these trade barriers. In addition, approximately US$1.2 billion in annual sourcing from India now incurs a 26% tariff, further straining Boeing’s cost structure.
  
  
• Overall Supplier Uncertainty: A significant 94% of aerospace executives report that these disruptions moderately to severely impact parts shortages.
  
  

The 18-Month Outlook (April 2025 – October 2026)

The combined pressures of production shortfalls and new tariffs suggest a challenging near-term scenario:

• Cost Increases: The aerospace industry may face an estimated annual cost increase of around US$5 billion, with aircraft prices potentially rising by over 10%.
• Extended Delivery Delays: Existing production backlogs could widen if delays persist.
• Mitigation Strategies: In response, OEMs stockpile parts ahead of tariff increases, and there is a gradual push toward reshoring critical component production (e.g., electronics). Moreover, the industry is actively lobbying for political exemptions to alleviate some tariff burdens.

Bottom Line

US commercial aircraft manufacturing and parts imports are at a critical juncture. While the import market remains strong and concentrated, production challenges—intensified by Boeing’s operational setbacks—continue to strain manufacturing capacity. Introducing new tariffs further raises costs and disrupts supply chains, adding pressure to an industry grappling with significant production backlogs.

Industry stakeholders must prioritize strengthening supply chain resilience, speeding up digital transformation in supplier management, and advocating for specific tariff exemptions. These measures will ensure the US aerospace industry can navigate these interconnected challenges and remain competitive through 2026.
