About - Gremark Technologies Inc.

GTI is a Chicago-area 3PL specializing in consumer electronics — returns evaluation, grading, refurbishment, electronic repair, asset recovery, provisioning, and B2B fulfillment. Operating since 1994, GTI serves major brands including Walmart, Home Depot, Lenovo, HP, Dell, and IBM from a 54,000 sq ft facility in Romeoville, IL — strategically located 30 miles southwest of Chicago with direct access to I-55 and I-80. We handle the full post-sale device lifecycle: inbound returns, cosmetic and functional grading, repair, repackaging, imaging, and outbound deployment. GTI is a single-partner solution for brands that need more than a warehouse — we combine physical operations with the technical expertise to process, evaluate, and redeploy electronics at scale.
