DOVER, OH — Effective Jan. 15, 2021, or as contracts allow, Dover Chemical Corp. is increasing off-list prices for all grades of Doverphos® liquid alkyl and aryl organo-phosphite (esters), including tris-nonylphenol phosphite (TNPP, all grades) by $ 0.10 per pound.

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

All orders placed for shipment on or after Jan. 15, 2021 will be affected by this increase.

Standard lead-time for bulk orders is 8-10 calendar days, and lead-time for all packaged goods is 14 calendar days.
