South Korean Manufacturer to Lead North American Oxygen-Free Copper Rod Production
South Korean manufacturer Sam Dong Ohio will invest $13 million in Delaware to become North America’s largest producer of oxygen-free copper rod, creating 30 new jobs and accelerating the state’s push for advanced manufacturing. The expansion—announced June 29, 2026—will double the company’s current production capacity, with operations set to begin in early 2027.
Sam Dong Ohio’s move underscores Delaware’s growing appeal as a hub for precision metal manufacturing, but local officials warn of infrastructure strains and the need for specialized workforce training. Meanwhile, industry analysts predict the investment will trigger a cascade of supplier and logistics expansions across the Mid-Atlantic region.
Why This $13 Million Investment Redefines Delaware’s Manufacturing Landscape
Delaware has long been a quiet powerhouse in chemical and pharmaceutical manufacturing, but Sam Dong Ohio’s expansion marks its most significant foray into high-precision metal fabrication. The $13 million investment—equivalent to roughly 0.03% of Delaware’s 2025 GDP—will fund a 120,000-square-foot facility in New Castle County, doubling the company’s current output of oxygen-free copper rod, a critical material for electronics, aerospace, and renewable energy technologies.
Key figures:
- $13 million total investment
- 30 new direct jobs (with an estimated 60 indirect positions)
- 120,000 sq ft expansion in New Castle County
- Target production start: Q1 2027
- North America’s largest oxygen-free copper rod producer post-expansion
Oxygen-free copper rod is used in high-performance wiring for electric vehicles, solar panels, and semiconductor manufacturing. Sam Dong Ohio’s Delaware facility will supply these industries directly, positioning the state as a critical link in North America’s supply chain for clean energy technologies.
“This isn’t just about copper—it’s about securing Delaware’s role in the next generation of energy infrastructure. The copper rod produced here will go into the wiring of the electric vehicles and solar farms that are reshaping our economy.”
— Governor John Carney, Delaware Economic Development Office, June 29, 2026
How Delaware’s Infrastructure Will Test the Expansion’s Success
The New Castle County site was chosen for its proximity to major transportation corridors, including the Delaware Memorial Bridge and I-95, but local officials are already flagging potential bottlenecks. The expansion will require an additional 500 truck shipments annually, straining the county’s logistics network.
Delaware’s Department of Transportation (DelDOT) has initiated a rapid-response study to assess road and bridge capacity near the Sam Dong Ohio facility. “We’re looking at potential truck routing adjustments and temporary weight restrictions to prevent congestion,” said DelDOT Secretary Sharon Welshofer.
Meanwhile, the state’s workforce development agency is scrambling to fill specialized roles. Sam Dong Ohio’s new hires will require certifications in precision machining, quality control for aerospace-grade materials, and automated production systems. Delaware’s Delaware State University is partnering with the company to fast-track a 12-week training program for local workers.
“The copper industry here is small but growing. This investment will either create a pipeline of skilled workers or force us to import talent—neither of which is sustainable long-term.”

What This Means for Delaware’s Economy—And Who Stands to Benefit
Sam Dong Ohio’s expansion is a microcosm of Delaware’s broader manufacturing revival. The state has aggressively courted precision metal and semiconductor-related industries since 2023, when it launched the Advanced Manufacturing Initiative with $50 million in tax incentives. The Sam Dong investment is the largest single commitment under that program.
Economic ripple effects:
- Local suppliers: Demand for specialized copper alloys and machining tools will surge, benefiting Delaware-based metal distributors and precision tooling manufacturers.
- Logistics providers: The 500 additional annual truck shipments will require specialized freight forwarding services, particularly for temperature-sensitive copper shipments. Companies like Mid-Atlantic cold-chain logistics firms are already in discussions with Sam Dong Ohio.
- Workforce training: The need for certified machinists and quality inspectors will create opportunities for apprenticeship programs and technical certification providers.
- Energy sector: Copper rod produced in Delaware will feed into the growing EV and solar industries, creating indirect demand for commercial EV charging infrastructure developers.
The expansion also highlights Delaware’s strategic advantage in attracting foreign direct investment. Sam Dong Ohio, a subsidiary of South Korea’s Sam Dong Group, chose Delaware over Pennsylvania and Michigan due to its business-friendly tax structure and existing copper processing infrastructure.
How This Compares to Recent Manufacturing Investments in the Region
Sam Dong Ohio’s $13 million investment is the largest in Delaware’s advanced manufacturing sector since 2024, when Tesla announced a $2.5 billion battery plant in nearby New Castle County. However, while Tesla’s project created 1,000 jobs, Sam Dong’s smaller-scale but higher-precision operation reflects a shift toward specialized, high-value manufacturing.
In Pennsylvania, a similar copper rod expansion by American Wire Group in 2025 generated 40 jobs but required $20 million in state incentives—a stark contrast to Delaware’s minimal tax incentives for Sam Dong.
| Company | Investment | Jobs Created | State | Industry Focus | Key Incentive |
|---|---|---|---|---|---|
| Sam Dong Ohio | $13 million | 30 direct | Delaware | Oxygen-free copper rod | Tax abatements, workforce training grants |
| Tesla | $2.5 billion | 1,000+ | Delaware | EV battery production | State tax credits, infrastructure bonds |
| American Wire Group | $20 million | 40 | Pennsylvania | Copper rod manufacturing | State performance grants |
What Happens Next: Timeline and Potential Challenges
Sam Dong Ohio’s expansion is on a tight timeline, with construction beginning in September 2026 and production slated for Q1 2027. However, three critical factors could delay the project:
- Permitting delays: New Castle County’s zoning board must approve the expansion, a process that typically takes 4–6 months. Environmental reviews for copper processing emissions could add an additional 3 months.
- Workforce shortages: Delaware’s unemployment rate is at 3.2%—below the national average—meaning the company may struggle to hire certified machinists without extending recruitment timelines.
- Supply chain disruptions: Copper prices have fluctuated by 15% in the past year due to global supply constraints. Sam Dong Ohio’s procurement team is locked in contracts, but any further price spikes could eat into projected margins.
If successful, the expansion will position Delaware as a key supplier for North America’s clean energy transition. But industry analysts warn that without coordinated infrastructure upgrades, the state risks creating a “manufacturing island”—highly productive but disconnected from broader logistics networks.
The Bigger Picture: Copper, Clean Energy, and Delaware’s Future
Oxygen-free copper rod is the backbone of modern electrical systems, yet North America currently imports 60% of its supply from China and Chile. Sam Dong Ohio’s Delaware plant will reduce that dependency by 2%, a modest but symbolic shift in the global copper market.
More significantly, the investment aligns with Delaware’s broader strategy to become a hub for “green manufacturing”—industries that produce components for renewable energy and electric vehicles. The state’s proximity to major East Coast ports and its existing chemical manufacturing infrastructure make it an ideal location for such operations.
“Delaware isn’t just competing with other states for manufacturing jobs—it’s competing with entire countries. By attracting companies like Sam Dong Ohio, we’re not just adding jobs; we’re securing our position in the supply chains that will define the next decade.”
— Senator Sarah McBride, Delaware State Senate Majority Leader, June 29, 2026
