KMG-Bernuth, Inc. is the leader in utility pole and railroad crosstie wood preservation chemicals in North America.

Pentachlorophenol (penta) and Creosote wood-preserving chemicals have played a critical role in the development of the nation’s transportation, communications, maritime and construction infrastructures.

For more than a century, Creosote treatments have protected railway ties, construction timbers and marine pilings from insect infestation and decay. For nearly as long, Pentachlorophenol (Penta) has been used by power generation and telecommunications companies to protect their utility poles.


We purchase Creosote from domestic and international suppliers and are positioned as the single-largest source of Creosote for the U.S. wood treating market. We are proud of our role in providing a ready and reliable source of Creosote supply in the U.S.

We store creosote in bulk storage tanks along the Mississippi River near New Orleans at Avondale, Louisiana and near Savannah, Georgia. We lease a fleet of approximately 120 tank railcars for the distribution of Creosote to wood treaters throughout the U.S.

  • Product of choice for treating railroad crossties
  • Single-largest source of Creosote supply in the U.S.

KMG-Bernuth is the only manufacturer of Penta in North America. Our Penta products include Penta blocks and solutions. KMG de Mexico, our subsidiary in Mexico, manufactures technical Penta and also produces and sells hydrochloric acid, which is a byproduct of the Penta manufacturing process.

At our facility in Matamoros, Mexico, we manufacture solid Penta blocks, which we sell to our wood treating customers, or make it into a liquid solution of Penta concentrate at our Matamoros, Mexico facility and at our formulation facility in Tuscaloosa, Alabama.

Why choose Penta from KMG-Bernuth?

  • Highly effective against insect damage and weather decay
  • 60-plus year track record of environmental safety
  • End-of-life Penta-treated poles can be reused and recycled or burned for energy in combustion units and industrial boilers
  • Environmentally-friendly option relative to steel poles, which consume eight times more fossil fuel in the manufacturing process than wooden poles, according to the Swiss Federal Laboratories for Materials Testing and Research.
