R.J. Reynolds is raising prices on Camel, Kool and other cigarette brands, joining competitor Philip Morris USA in continuing to boost prices to offset volume declines.

R.J. Reynolds is a unit of Reynolds American (RAI). The company is raising wholesale prices on brands such as Camel, Kool, Winston, Salem, Pall Mall and Doral by six cents a pack. Prices on some other brands such as Capri and Lucky Strike will go up by eight cents a pack.

Earlier this week, Altria Group Inc.'s (MO) Philip Morris USA unit announced price hikes on Marlboro and other cigarettes. For years, cigarette makers in the U.S. have faced falling volumes, hurt by smoking bans and higher taxes. They have sought to shore up profits by steadily hiking prices.
