Stepan Announces Increase on Rigid Polyester Polyols

May 14, 2021

Dear Valued Customer:

Effective July 1, 2021, or as contracts allow, Stepan will increase the price for STEPANPOL® and
TERATE® Rigid Polyester Polyols used in the Americas by $0.12 per pound. This increase is
necessary due to the continued rapid rise in raw material and transportation costs.
Due to the magnitude of cost increases in flame retardants, all STEPANPOL® and TERATE®
products containing flame retardant will increase by an additional $.03 per pound for a total of $.15
per pound.

We appreciate your support and value your continued business. Your Stepan sales representative
will be in contact with you to address any questions or concerns.
