Based In The Midwest.
Trusted Around The World.
We bring expertise and peace-of-mind to global component supply.
With more than 40 years in the ag and industrial markets, Concentric International understands how much can depend on a single part—and the pressure that comes with specifying or purchasing it. We combine our long-standing global manufacturer relationships with disciplined inventory planning to help OEMs and industrial buyers move forward with confidence, not compromise.
What Drives Us
Enhanced Operational Efficiency
Every volume customer has a single point of contact and multiple ways to contact that person. Concentric also believes in the power of face-to-face communication. Our sales representatives frequently consult in person with all our volume clients.
Advanced Inventory Management
We operate our warehouses on First In First Out (FIFO) principles, using the latest technology to create a virtual warehouse to make things more efficient. Our virtual warehouse system knows the location and age of every piece of inventory and creates pick lists that maximize efficiency of product and work flow through each facility.
Rapid Nationwide Distribution
Through careful management and integration into our customers’ sales forecasting processes, Concentric anticipates demand and keeps our warehouses stocked adequately to provide Just In Time (JIT) supply to our customers.
Fast & Efficient Product Distribution
Delivery capabilities are also enhanced by state-of-the-art Enterprise Resource Procurement (ERP) and Electronic Data Interchange (EDI) systems. Concentric’s electronic delivery and distribution tracking systems are integrated into many of our customers’ information technology systems, giving them instant access to detailed shipping information.
Tailored Solutions
We work with our long-standing global manufacturing partners to bring customers exceptional quality, value and tailored solutions. Concentric takes responsibility for every piece and part being manufactured at the highest quality and to each wholesale and OEM customer’s exacting standards. Your satisfaction is always guaranteed. No excuses.
Custom-Made Products
Concentric works directly with wholesale and OEM customers to develop variations of existing products and entirely new components to meet their unique needs. Need a new component? We’re happy to work with you and get the exact part you need to get the job done.
Our History
Founded as Iowa Export-Import
Concentric International began in 1983 as Iowa Export-Import, founded by Des Moines businessman John Ruan. Long before global trade became commonplace, Ruan saw the opportunity to connect American companies with international markets and products. The company initially focused on navigating the complex regulatory, cultural, and logistical challenges of international trade.
First Globally Sourced Product
In 1986, the company began manufacturing and marketing its first globally sourced product: rubber-to-metal molded agricultural teeth made in South Korea. Today, Concentric is the world’s leading provider of these high-performance teeth used in baling, forage harvesting, raking and vegetable harvesting applications.
Expansion into Power Transmission
As global supply became more accessible, Iowa Export-Import evolved from trade facilitator to global product supplier. The addition of power transmission components in 1990 marked a strategic shift toward building a long-term product portfolio for OEM and industrial customers.
Electrical & Control Solutions
In 2003, Concentric expanded again by launching its line of electrical products. Linear actuators, the primary product in this category, are now used in countless commercial and custom applications worldwide.
In 2012, Iowa Export-Import rebranded as Concentric to reflect its evolution into a fully integrated global supply partner. The new name signaled a deeper focus on engineering collaboration, product integration, and long-term supply partnerships.
Today, Concentric International operates as a sales, warehousing, and distribution partner for global manufacturers. With more than 40 years of experience, we help OEMs and industrial buyers access dependable, competitively priced components backed by forecasting, warehousing, and application expertise.

Frequently
Asked Questions
When was Concentric International founded?
Concentric International was founded in 1983. For more than four decades, we have served OEMs and industrial manufacturers with dependable component sourcing, warehousing, and distribution support. Our longevity reflects consistent performance, long-term partnerships, and disciplined supply planning.
What does “Concentric” mean?
The name reflects alignment. We operate at the center of a supply network that connects global manufacturers, domestic warehousing, and OEM production teams. Our role is to ensure every moving part works in coordination—so your production stays on track.
Is Concentric International a manufacturer?
No. We are a sales, warehousing, and distribution partner for global manufacturers. We carefully select and represent proven factory partners, then support customers with domestic inventory, forecasting, and application expertise.
How large is your operation?
We manage millions of dollars in inventory and support customers across the United States and internationally. Backed by the resources of the Ruan Group, we have the financial strength and operational infrastructure to support long-term supply programs.
Where is Concentric International located?
We are rooted in the Midwest, positioning us close to many agricultural and industrial manufacturers. While our relationships extend globally, our operations and warehousing are structured to support domestic delivery reliability.
What type of companies typically work with you?
Our customers include:
- Agricultural OEMs
- Industrial OEMs
- Aftermarket Distributors
Many of the professionals we work with are engineers specifying components or buyers responsible for maintaining production continuity.
Do you support new product development?
Yes. We frequently assist during the design phase of new equipment and product lines. Our team evaluates performance requirements, compatibility, and long-term availability to ensure the selected component can scale with production.
What does a long-term partnership look like with Concentric?
A long-term partnership includes collaborative forecasting, aligned inventory planning, consistent communication, and proactive supply management. We plan months—and often quarters—ahead to reduce surprises and maintain continuity.
How do you approach supply chain risk?
We reduce supply chain risk through:
- Vetted global factory partnerships
- Forward-looking forecasting
- Domestic warehousing
- Clear communication around lead times
- Inventory programs aligned to real demand
Rather than reacting to shortages, we plan for stability.
What kind of support can customers expect after the first order?
Ongoing support is central to our model. We monitor demand patterns, adjust forecasts as needed, communicate proactively about market changes, and maintain consistent inventory availability. Our goal is sustained reliability, not a one-time shipment.
What role does warehousing play in your model?
Warehousing allows us to bridge global production and domestic manufacturing schedules. By stocking inventory locally, we reduce lead time variability and support just-in-time delivery programs.
Why has Concentric International remained successful for over 40 years?
Our success is rooted in disciplined planning, trusted relationships, and consistent execution. We focus on products that matter, serve markets we understand, and operate with long-term perspective rather than short-term transactions.
How do you decide which product lines to represent?
We evaluate product lines based on performance, durability, consistency, and long-term manufacturer reliability. We only represent products that meet the real-world demands of agricultural and industrial applications.
What is the first step in working with Concentric International?
The first step is to contact a sales representative and share your application requirements, specifications, or sourcing goals. From there, we assess fit, recommend solutions, and outline a supply plan that aligns with your timeline and production needs.
