Why should I trust Thomas' resources?

As the leading North American sourcing platform, we have prided ourselves on providing reliable and actionable information that helps industry professionals get the job done since 1898.

Companies from small businesses to Fortune 500 organizations source using our platform, and our catalog libraries are supplemented with products directly from top manufacturers. Thomas is also a trusted data resource for major media outlets such as CNN and the Wall Street Journal

We are a company of engineers, analysts, researchers, and experienced experts in the industrial marketplace working to help the North American manufacturing industry grow. We’ll be going over the processes behind our most popular services that ensure we offer the best and most reliable intel and services for industry, from our 500,000+ detailed supplier profiles to our industrial surveys and reports. 

How We Validate Supplier Profiles

Supplier Profiles

As our most major offering, there are over 500,000 North American supplier profiles across Thomasnet.com, and every one of them has been added and updated by one of our 100+ expert supplier analysts and engineers. How trusted are our listings? 93% of Fortune 1000 companies use Thomas to source, and our platform has over 1.1 million registered users, with another 20,000 new users added every month. 

Each supplier is vetted by an analyst, who uses the data submitted by the company, including its products and services, website, and certifications, to build up a listing for it and place it in the most relevant categories. Additional vetting and verification is done for companies with a Thomas Registered or Thomas Verified badge. Thomas Registered suppliers get special verification for their primary offerings to ensure buyers can easily find them in categories they specialize in, while Thomas Verified Suppliers receive additional vetting for all of their products and services to provide a complete picture of their offerings. We break down the verification processes for these badges in more detail in our article on supplier badging

Special vetting and validation are also offered for suppliers with a special badge, such as the COVID-19 Supplier badge, which marks companies that have stepped up to offer crucial products and services to combat the 2020 pandemic. Our analysts validate the pandemic-related offerings of each COVID-19 supplier before awarding them a badge, as many have pivoted so quickly the offerings may not yet appear on their websites. If your company has readily available materials or supplies, join the 5,000+ who have already volunteered to help overcome the pandemic.

Our experts do their best to ensure listings have the most up-to-date information, but since the industrial landscape constantly changes, our content is subjected to updates in real-time and we cannot guarantee 100% accuracy. If you notice outdated listing information, please help us out by letting us know. You can do that by clicking on the feedback box on the right side of the page. 

How We Curate Product and Service Categories

Product and Service Categories

Thomasnet.com has a constantly evolving selection of over 75,000 categories of products and services to source from, arranged in a branching system carefully curated by our taxonomy team. As opposed to generic search engines, which use algorithms based on keywords, our categories all correspond and are deep-linked to actual products and services by our Content Analyst team. Our experts constantly research and add over 400 new sourcing categories a year to keep up with current trends and all of the products coming into the market. 

To keep our product and service categories accurate and up to date, our taxonomy specialists also update, clarify, and remove dozens of outdated categories every year. Because of this work, Thomas is able to ensure users are able to find the products and services they need whether it was invented six months ago or 100 years ago. 

How We Build Catalogs 


Our product and CAD catalogs are built from information provided directly from hundreds of the top suppliers in industry, such as Oriental Motor, Parker Hannifin, and Baldor Electric. Our team of in-house certified engineers works directly with suppliers to build custom product catalogs using supplier source documents such as PDFs, excel files, and sales drawings. Engineers at Thomas then create a complete taxonomy and structure in each catalog allowing buyers to easily navigate a supplier’s offerings and send RFQs. 

For custom manufacturers, our engineers build special catalogs to showcase each manufacturer’s unique capabilities. These catalogs also display portfolio examples that allow customers to get a gauge on the supplier’s expertise before sending an RFI.

How We Create our CAD Catalogs 

CAD Catalogs

We understand the importance of on-demand product files and information in our highly-competitive industrial marketplace. One of our main features to help in your research and decision making process is our completely digital 2D/3D CAD and BIM services. Using Thomas’ CAD catalogs you can gain access and download part number specific models and data to use in your projects instantly.

Thomas’ in-house engineering team draws virtually all of our CAD models from scratch to create parametric models to provide your end users with the information needed to simplify their jobs. We have assisted dozens of leading companies to bring these files to you, including Timken, and Swagelok. We provide buyers with access to over 10 million 2D and 3D CAD drawings.
