WASHINGTOn — Dow Chemical Co. will raise its prices by up to 20% almost immediately to offset the soaring cost of energy, and the CEO of the chemical giant lashed out at Washington today for failing to develop a sound energy policy.

Dow supplies a broad swath of industries, from agriculture to health care, and any sizable price jump would likely affect almost all of them.

The price increases will take effect Sunday and will be based on a product’s exposure to rising costs. Dow said it spent $8 billion on energy and hydrocarbon-based feedstock, or raw materials, in 2002 and that could climb fourfold to $32 billion this year.

“For years, Washington has failed to address the issue of rising energy costs and, as a result, the country now faces a true energy crisis, one that is causing serious harm to America’s manufacturing sector and all consumers of energy,” the Chairman and Chief Executive Officer, Andrew Liveris, said in a statement.

“The government’s failure to develop a comprehensive energy policy is causing U.S. industry to lose ground when it comes to global competitiveness, and our own domestic markets are now starting to see demand destruction throughout the U.S.”

Mr. Liveris said soaring costs for Dow are “forcing difficult discussions with customers.”

Midland, Mich.-based Dow Chemical makes everything from the propylene glycols used in antifreeze, coolants, solvents, cosmetics, and pharmaceuticals, to acrylic, acid-based products used in detergents, wastewater-treatment, and disposable diapers.

It makes key ingredients used in paints, textiles, glass, packaging, and cars.

Its products are sold in 160 countries.

The company last month reported a 3% drop in quarterly earnings, despite a 42% jump in feedstock and energy costs.

Dow shares rose 30 cents to $40.53 in early trading.
