Best Siemens Product Companies in the United States

Quick Summary: Finding the perfect Siemens products for your company or project can be overwhelming at times. This guide will take you through five trusted and reputable companies in the U.S. that deliver Siemens equipment. From automation parts, electronic components, to industrial control systems, these suppliers have the experience and customer service to help provide you with a suitable product. This guide will help you understand what is different about each company, how each company fits your specific needs, and why it is very important to choose the correct supplier for your business to succeed.

Siemens is one of the largest industrial manufacturing companies in the world. They produce equipment that keeps factories operational, buildings at comfortable temperatures, and machines functioning properly. Their products range in scale from tiny electronic sensors to large industrial motors. 

Think of Siemens products as the brain and muscles of modern industry. Their programmable logic controllers (PLCs) tell machines what they need to do. Their motors and drives run conveyor belts in warehouses. Their building automation systems control heating and cooling in offices and hospitals. 

The United States industrial market uses Siemens technology extensively. Manufacturing plants, water treatment facilities, power stations, and commercial buildings all use Siemens equipment. Therefore, when this equipment has a need for replacement parts or an upgrade, businesses generally work with an authorized distributor and department vendor.

How the Siemens Supply Chain Works in America

Knowing how Siemens products are supplied to customers in the U.S. can help us grasp the importance of selecting the right supplier. Siemens does not typically sell directly to end-users; it works through a network of distributors, system integrators, and specialty suppliers. This arrangement creates advantages for customers by fostering competition among suppliers regarding pricing, service, and delivery speed. Corporations can select from a pool of suppliers, each based on their specific demands, rather than just a single source. 

Unfortunately, not all suppliers are qualified equally. Some suppliers carry large inventories, while other suppliers order their products only once they have an order to fill. Some suppliers are proficient in providing technical support, while other suppliers simply ship boxes. Some suppliers specialize in selling new product lines, while others suppliers excel in procuring obsolete parts. 

Top 5 Siemens Product Companies in the United States

1. Capitol Area Technology – The Technical Support Specialists

Capitol Area Technology is a customer-focused automation company. They serve customers who need more than products and typical vendor relationships. They focus on complete automation solutions, delivered with strong engineering support, and for the last decade have been building their reputation and engineering expertise in the mid-Atlantic region of the United States by solving complicated industrial automation problems.

What Makes Them Different:

Capitol Area Technology values relationships over transactional sales. Their employees are experienced automation engineers who know Siemens systems very well. When you call the company with a question or problem, you will always get to speak with people who have real-world experience with the same equipment and systems.

Capitol Area Technology is very good at custom panel building and system integration. They will design and install complete control systems, not just provide individual components. Their technicians can program Siemens PLCs, configure networks, and troubleshoot existing systems.

Best For:

• Companies upgrading old automation systems
• Projects requiring custom engineering work
• Businesses needing ongoing technical support
• Organizations seeking local partnerships with hands-on service

They focus their service model on education, helping customers to better understand their systems, instead of creating dependency that discourages learning. They recognize that long-term value will result even if they receive fewer service calls.

2. RS Americas – The Inventory Powerhouse

RS Americas is part of RS Group, a worldwide distributor with one of the largest selections of industrial products in North America. Their warehouse systems can quickly process orders and often ship same-day.

What Makes Them Different:

The RS Americas website allows users to search for hundreds of thousands of products and view an online catalog with detailed specifications, drawings, and compatibility information for those products. Engineers can even compare similar products side-by-side and technical documents without calling.

There are different shipping options for different levels of urgency. If you need a part for tomorrow, expedited shipping is available to most areas in the U.S. If you are working on a project for the future, standard shipping is still days, and is cheaper than expedited shipping.

Through volume purchasing power with Siemens, they can offer competitive pricing. Larger companies often negotiate contracts with RS Americas for company-wide supply agreements to simplify procurement and control costs.

Best For:

• Large corporations with standardized purchasing processes
• Projects requiring multiple products from different manufacturers
• Maintenance departments need reliable inventory access
• Companies prefer online ordering over phone calls

RS Americas serves customers who value efficiency and self-service capabilities. Their system works well for experienced buyers who know exactly what they need.

3. Control Parts – The Rare Parts Hunters

Control Parts has established itself as a leader in the industry. Their niche is helping find discontinued and hard-to-find Siemens parts. When suppliers claim a part is “no longer available”, Control Parts is often able to find it.

What Makes Them Different:

Industrial equipment can run for decades. A factory can have equipment that was built in the 1990s, and it may still work like it is brand new. When a component fails, however, the original manufacturer may have stopped making the component long ago. Purchasing a new machine could cost tens of thousands of dollars. So finding the rare discontinued part saves companies a tremendous amount of money.

Control Parts has relationships with repair shops, surplus dealers, and overseas suppliers. Their staff searches internationally for specific components. Most parts will be refurbished and tested to the original specifications.

They even perform repairs on some Siemens products. Sometimes, repairing an existing part is less than buying a new one. Their technicians rebuild drives, controllers, and operator panels.

Benefits of Using Control Parts:

• Extends the life of older equipment
• Reduces emergency replacement costs
• Provides alternatives when new parts aren’t available
• Offers expertise in legacy Siemens product lines

Best For:

• Facilities with older equipment still in production
• Companies facing discontinued part emergencies
• Maintenance teams supporting legacy systems
• Organizations seeking cost-effective repair options

Their customer base includes manufacturing plants, utilities, and process industries where equipment upgrades happen gradually over the years.

4. BDi Express – The Speed Specialists

BDi Express has an extensive distribution network across North America, dedicated to quick delivery. They store inventory in select locations across North America to ensure the shipment arrives sooner. Their logistics systems are designed to get the parts to the customer as fast as possible.

What Makes Them Different:

Every hour that a customer is shut down due to a broken part costs money, so BDi Express knows urgency is everything. Their computerized inventory and ordering system flags and processes orders for urgent deliveries when they arrive. They also partner with regional carriers to ensure their customers get the product faster.

Their inventory strategy is both wide and deep. BDi Express does not carry all products, but it carries frequently turned Siemens products that are only replaced periodically. This gives BDi Express the ability to stock the most frequently requested items on the shelf to ship them right away.

In addition to simply the shipping confirmation on your order, BDi also has a customer-ordered product tracking database. The customer will get updates on exactly where their product is located, with the expected time of arrival when available. Having a clear view of the shipping progress allows customers’ maintenance teams to prepare and plan for a product’s arrival.

Features for Time-Sensitive Situations:

• Same-day shipping for orders placed by the cutoff times
• Weekend and after-hours emergency services available
• Strategic warehouse locations reduce transit times
• Dedicated account managers for priority customers

Best For:

• Manufacturing facilities where downtime is extremely costly
• Maintenance departments managing emergency repairs
• Companies in remote locations need fast delivery
• Industries with just-in-time maintenance programs

BDi Express appeals to operations managers who understand that faster delivery often justifies slightly higher costs compared to the expense of extended downtime.

5. TME Electronic Components – The International Connector

TME Electronic Components specializes in the European look in the USA. Originating from Poland, TME has grown globally with a reasonable price point internationally; sourcing is their specialty, whether it be on the electronic components side or the smaller product offerings from Siemens.

What Makes Them Different:

TME has a full range of stock from Siemens in sensors, switches, contactors, and various control devices to choose from, alongside thousands of additional electronic components that other manufacturers make. Such coverage makes it easy for engineers to apply components to their projects with just one source.

The TME website also has beneficial search and technical/documentation capabilities to select items. Any product has specifications, certifications, and compatibilities to assess. They are also available in multiple languages and currencies since it is an international source.

TME serves its USA customers in an efficient manner because it utilizes a global distribution model. Products ship from distribution points that are most favorable to the needs of their customers and added capabilities of sourcing manufacturers. Often, they deliver boats to customer locations sooner than the anticipated delivery time from an international supplier.

Benefits for Different Customers:

• Small to medium businesses appreciate their accessible pricing
• International companies value familiar European products
• Design engineers like their comprehensive component selection
• Research facilities find unique sensors and measurement devices

Best For:

• Electronic design projects requiring diverse components
• Companies sourcing products for international equipment
• Small businesses seeking competitive pricing without contracts
• Organizations need both Siemens and other European brands

TME serves customers who think globally and appreciate suppliers who understand international standards and specifications.

Benefits of Working With Authorized Siemens Suppliers

All five companies on this list are trustworthy sources with good standing with Siemens. This means they provide the following guarantees: 

1. Product Authenticity – You’re getting ‘real’ Siemens products and not counterfeit or knockoff products. Counterfeit industrial parts pose safety risks and reliability concerns.
2. Warranty Coverage – Real products come with manufacturer warranties. If something fails prematurely, you have warranty recourse. 
3. Technical Accuracy – Product specifications are the same as those of Siemens. You know the parts will fit and function as intended. 
4. Compatibility – Real Siemens controllers and devices are guaranteed to work with Siemens programming their networks. 
5. Safety Certifications – Real Siemens products have the proper UL, CE, and other safety certifications as required by law.

In the end, while saving a few dollars by ordering from an unknown supplier seems appealing, it will cost you a lot more when there is a problem. It’s better to order from established suppliers who stand behind their products.

Final Thoughts

Siemens products power key parts of the American industry. Selecting the right supplier can make all the difference in how easy and efficient accessing these products is, regardless of ultimate priority. Whether you are seeking technical support, depth of inventory, expertise for hard-to-find parts, speed of delivery, or international ties, at least one of these five suppliers will likely provide what you are looking for. 

Just remember that the cheapest supplier is not necessarily the most cost-effective. Take a moment to consider the total cost. The total cost should not only include the purchase price of products, but also consider shipping, potential downtime, and whatever level of technical support is needed. The peace of mind received is worth whatever the price.

Creating dependable relationships with wholesalers, all next-level supplier engagement creates value over time. Your immediate purchase price is hardly the entire picture of value creation.

That said, it’s certainly worth the time and effort to check out their websites, phone their customer service, and test their ordering process. The supplier that ultimately settles into your organization seamlessly might surprise you. Your specific needs, wants, and priorities will matter more than whatever someone popular recommends.

What’s most important is that you determine your own best supplier as you secure quality suppliers to support your equipment needs, and beyond, you can start to focus on what you do well- running your operations effectively and serving your customers well. Ultimately, this is what good suppliers deliver- confidence, focus on what you do best, while they work with you to deliver the right products at the right time.
