What is a surplus consignment program?

Through our Consignment Program, SIGMA pays competitive rates for your used MRO components from a variety of categories including automation, electrical, and industrial parts. We will take all the work out of selling your inventory, from beginning to end.


Consignment is ideal for companies who may not have the time or resources to sell parts on their own. We'll handle the hard work and sell your parts for you, so you can put your energy into other important projects.


We make the process simple with an on-site inventory inspection and arranged product transportation back to SIGMA. Using our vast internal customer network, we'll list your spare parts and find a buyer as soon as possible.


SIGMA Surplus can sell your parts on consignment across all industries and major brands.
