SIGMA Surplus Trade-In Program

Turn old automation parts into equipment you need

As part of our mission to empower customers and fulfill their automation needs, SIGMA Surplus is proud to introduce the all-new Trade-In Program. This initiative allows anyone to trade in their spare automation components to SIGMA Surplus for store credit, which they can use to purchase any of the 100,000+ products we sell. This program allows you to turn your unused parts into new, reliable components from the brands you know and trust.


Why should I trade in parts?

It’s simple! The answer is value. Each and every item traded into SIGMA Surplus is worth 15% more in store credit compared to cash. This program is designed to stretch your dollar even further and maximize your value when trading spare components.

As production equipment ages and needs new parts, you can turn that store credit into essential replacements that get your production back online, all without dipping into your business’s maintenance fund.

Here at SIGMA Surplus, we’ve built a marketplace of used, open-box and new automation solutions. We buy and sell parts reliably sourced from organizations like yours. This program is the latest way in which we add value for our customers, beyond selling spare parts.


How it works

To take advantage of the SIGMA Surplus Trade-In Program, all you need to do is sell us your parts as you normally would. We offer multiple flexible options designed to clear production floor space and earn you maximum revenue. Just let your purchasing agent know you’d like store credit, and we’ll assign it to your SIGMA Surplus account.

That’s it - no hoops to jump through or any extra steps needed. We strive to make the process of selling your surplus as simple as possible so you can get back to business.
