Processes, Warranties, and Shipping

How It Works

SIGMA Surplus employs trained technicians and mechanics to remove valuable and functional parts off of manufacturing equipment. These items, which can include components like electronics, servos, pneumatics, and much more.

These parts are then processed, photographed, and listed for sale on our website by SIGMA’s e-commerce team. Each and every item sold by SIGMA Surplus offers identical performance compared to their brand-new counterparts, all at a fraction of the price. Why pay more when you don’t have to?

From the moment your order is placed, you can enjoy peace of mind with expedited and international shipping options, as well partnering with a door-to-door courier service. We stand behind our products with a standard 30-day warranty on all parts, as well as a two-year warranty for each component we test. 


We Buy Spare Parts, Too

Another major component of SIGMA Surplus is our ability to purchase customers’ spare parts at a competitive rate. We offer a variety of programs designed to accommodate a wide variety of needs and budgets, including contactless and bulk item arrangements. We offer four main programs in which customers can sell us their automation components:

  • Crate Program - SIGMA Surplus will ship a crate to your business along with packing materials. You’ll fill the crate with components you wish to sell and ship back to us. From there, we’ll make an offer and purchase your spare parts.

  • Consignment - Our team will visit your facility and examine the spare parts you wish to sell. From there, we arrange shipping to our facility, where we will examine and catalog your inventory. Lastly, we photograph, list, and market your parts on our online SIGMA Surplus store.

  • Inventory Evaluation - With our Inventory Evaluation Program, our team evaluates your inventory of the spare MRO components you wish to sell. All you need to do is send an itemized list and pictures of the spare parts and we will do the rest.

  • On-Site - Our team will visit your facility, assess your spare parts, and make a competitive offer.

These programs are perfect for companies that may not have the time or manpower to assess and sell their own inventory. Whether you’re in a time crunch to clear production facility space or looking for additional revenue, SIGMA Surplus is here to make it easy.
