We pay competitive rates for automation, electrical, and industrial parts.



Sigma Surplus offers you three ways to sell your spare parts:

Crate Program

SIGMA Surplus makes it easy to sell your surplus parts and components. We send you a crate to fill with your items, arrange pickup, inventory all items and send you an offer.

Lot Purchase

Companies often overlook the value in their spare parts inventories. Whether you are consolidating operation sites, closing a plant, extracting a production line, or looking to reduce MRO carrying costs, SIGMA Surplus pays competitive rates for your unused parts.

On-Site Visit

SIGMA Surplus will visit your location, take inventory of your parts for sale, and make an offer. Our flexible options include removal and shipping to free up your space and maximize value quickly.
