TNPP Price Increase Effective April 1, 2022

Effective April 1, 2022, Dover Chemical Corporation is increasing off-list prices for all grades of Doverphos® tris-nonylphenol phosphite (TNPP, all grades) by $ 0.25 per pound.

This increase is necessary due to 1) continued increases in raw materials; and 2) increases in freight costs on a global basis 3) higher operational costs due to energy and reduced availability of trucking and raw materials. 

All orders placed for shipment on or after April 1, 2022 will be affected by this increase.  Previously confirmed orders will be re-priced with the new increase.

Standard lead-time for bulk TNPP orders is 14 calendar days (2 weeks), and lead-time for all packaged TNPP goods is 42 calendar days (6 weeks).
