Exhibit Space Wait List

Thank you for your interest in exhibiting with us in Philadelphia!

Our 2026 Expo Hall is officially SOLD OUT.

We do occasionally receive cancellations. If you’d like to join the 2026 waitlist, please select “Start” and complete the form.

Vendors on the waitlist will be contacted in the order they joined as space becomes available. You will have 24 hours to accept or decline the space and to secure MSA Vendor Membership if you are not already a member.

After May 1, only current MSA vendor members will be contacted, in the order their waitlist submissions were received.

NOTE: All vendors must be current members of MSA. Learn more about MSA Vendor Membership HERE.
