As the global economy continues to evolve, industries that depend on raw materials—particularly steel and aluminum—must keep a close eye on policy changes that impact sourcing, pricing, and supply chains. One of the most influential U.S. trade regulations in recent years has been Section 232 of the Trade Expansion Act of 1962. Introduced to protect national security interests, this provision has had far-reaching consequences for industries such as aerospace, construction, and manufacturing.
In this blog, we’ll explore what Section 232 is, how it affects metal buyers, and why companies are increasingly turning to domestic suppliers like Coastal Metals to navigate this complex trade environment efficiently and cost-effectively.
What Is Section 232?
Section 232 gives the President of the United States the authority to investigate and take action if imports of certain materials are determined to threaten national security. The idea is to ensure that the U.S. maintains a strong domestic industrial base capable of supporting defense and critical infrastructure needs.
Why Was It Enforced for Steel and Aluminum?
In 2018, following recommendations from the U.S. Department of Commerce, the federal government imposed a 25% tariff on steel imports and a 10% tariff on aluminum imports from a range of foreign countries. The reasoning was that global overproduction and dumping of cheap metals—particularly from China—were undercutting U.S. producers and jeopardizing the ability to manufacture defense and infrastructure materials domestically.
Since then, the impact of Section 232 tariffs has reshaped procurement strategies across multiple industries.
How Section 232 Affects Metal Buyers
Whether you’re in aerospace, heavy equipment, construction, or industrial manufacturing, you’ve likely experienced the ripple effects of Section 232—either directly through tariff costs or indirectly through material shortages, price volatility, and extended lead times.
Let’s break down how these changes have influenced different industries:
- Aerospace Industry
Aircraft components, engine casings, fasteners, landing gear, and structural supports are all reliant on specialty steel and aluminum alloys. Before Section 232, many aerospace companies sourced these metals from countries known for high-quality production at lower costs—like Germany, Japan, or Canada.
Post-tariff challenges include:
- Increased procurement costs due to import taxes
- Limited availability of specialty alloys domestically
- Regulatory compliance issues when switching suppliers or sources
As a result, aerospace manufacturers have had to reassess their supply chains, often prioritizing domestic materials that come without additional fees or international delays.
- Construction & Infrastructure
Large-scale construction projects depend on a wide range of steel products: I-beams, rebar, structural tubing, and plates. Margins in this industry are often tight, and material costs make up a significant portion of the overall budget.
Section 232 introduced:
- Price fluctuations that made it harder to lock in long-term bids
- Scheduling complications due to delayed shipments and port bottlenecks
- New emphasis on American-made steel, especially in government-funded projects
For civil engineering firms, contractors, and infrastructure developers, sourcing materials from U.S.-based suppliers like Coastal Metals has become an increasingly reliable and cost-effective strategy.
- Industrial & Manufacturing Sector
In the world of high-precision manufacturing—such as automotive components, power generation, and heavy equipment production—importing specialty bar stock or alloy plates was once standard. However, Section 232 has created new hurdles:
- Imported materials may now cost significantly more with the added tariffs
- Lead times have extended, particularly with global shipping disruptions
- Quality assurance becomes more difficult when switching to unfamiliar foreign suppliers
For these companies, domestic sourcing from suppliers that carry ASTM-, SAE-, and ISO-compliant metals is not just a workaround—it’s a strategic advantage.
Why Coastal Metals Is the Solution for Section 232 Challenges
With a broad range of large diameter bars, carbon steel, alloy steel, stainless steel, tool steel, and aluminum products, Coastal Metals provides tariff-free, U.S.-based solutions that mitigate the issues caused by Section 232.
Here’s how we help:
- Tariff-Free Metal Procurement
All of our inventory is sourced from within the United States or from approved trade partners with exemptions, meaning:

- Bronze bushings for marine use
We work with your engineering and procurement teams to ensure the right grade, size, and spec every time.
Planning for the Future: Staying Ahead of Trade Policy Shifts
Section 232 isn’t going away anytime soon, and the political landscape suggests trade policy will remain a powerful lever in global supply chain dynamics.
To future-proof your operations:
- Build relationships with domestic suppliers
- Standardize your specifications using U.S. and ISO certifications
- Request blanket or contract pricing to lock in costs amid volatility
- Audit your current supply chain for tariff exposure
By doing so, you’ll be better equipped to handle market fluctuations, minimize surprises, and stay competitive—even when policies change overnight.
Section 232 has redefined the way American industries source metal, elevating the importance of domestic suppliers who offer both compliance and cost stability. With tariffs still affecting imported steel and aluminum, working with U.S.-based providers like Coastal Metals gives you a crucial edge—ensuring materials are available, compliant, and competitively priced.
