TNPP Price Increase Effective September 15, 2021

Effective September 15, 2021, or as contracts allow, Dover Chemical Corporation is increasing off-list prices for all grades of Doverphos® tris-nonylphenol phosphite (TNPP, all grades) by $ 0.12 per pound.

This increase is necessary due to 1) continued increases in raw materials; and 2) increases in freight costs on a global basis due to higher operational costs and reduced availability. 

In addition, please provide three weeks lead time for all orders. All orders placed for shipment on or after September 15, 2021 will be affected by this increase.
