Aluminum Sulfate Antitrust Case

Summary

On December 1, Lockridge Grindal Nauen filed an antitrust class action on behalf of the City of Rochester, Minnesota, alleging price-fixing and bid-rigging involving liquid aluminum sulfate (aka “Alum”). Alum is used by municipalities to treat drinking and waste water, and by paper companies in the paper manufacturing process. On October 27, 2015, the United States Department of Justice and the FBI announced that a former executive of General Chemical Corporation pled guilty to rigging bids, allocating customers and fixing prices of alum over a 13-year period with other as-yet unidentified companies.

If you purchased alum between 1997 and today from General Chemical, Chemtrade Logistics, Gentek, Hawkins, C&S Chemical, GEO Specialty, USALCO, Kemira, Thatcher, or other suppliers of alum, you may have overpaid.

LGN Partner Joe Bruckner explains the case in the Duluth News Tribune.
