Industrial Materials Exchange (IMEX)

The Industrial Materials Exchange (IMEX) is a free listing service that helps your business locate useful materials and give away or sell surplus materials and hazardous products. Use IMEX to save on disposal and purchase costs, while helping the community conserve energy, resources, and landfill space.

What happens after I submit a listing?

This is what to expect after you send in your listing:

Listings on our website expire in 30, 60 or 90 day periods. You should receive an email three (3) days before your listing is set to expire asking if you would like to extend your listing for another 30, 60 or 90 days. If you do not respond to that email by the time your listing expires, your listing will be removed from the IMEX listings page.

How do I delete or change my listing?

For more information, contact IMEX at 206-296-4692 or imex@kingcounty.gov.
