Sulphur World Symposium (SWS) 2020 - CANCELED

After closely monitoring the risk and impact of COVID-19, and speaking at length with delegates and members of the community, the Sulphur World Symposium (SWS) 2020 in Chicago has been cancelled.

The health and safety of our delegates, guests, and our staff is of the utmost importance to us.

We appreciate your ongoing loyalty to TSI and thank you in advance for your understanding.

Refunds will be issued to all paid registrants.
