Washington D.C. is facing a lawsuit after its City Council passed legislation that becomes effective Jan. 1 requiring companies make clear whether their products are safe to flush down the toilet.

In a lawsuit filed Sept. 15 against D.C. in U.S. District Court, Kimberly-Clark attorneys argue the law unfairly and unwisely limits consumers’ right to choose products that have been proven to effectively meet their needs without causing or contributing to clogs.

“In seeking this court intervention, Kimberly-Clark is fighting for our consumers and standing up for our brands,” company spokesman Bob Brand told the Washington Post. “The District of Columbia has unfortunately passed a law that will severely restrict, if not eliminate, consumers’ ability to purchase flushable wipes in Washington D.C.”

Kimberly-Clark approaches the argument there is no standard for what is flushable, referencing how its products “meet or exceed widely-accepted industry guidelines for flushability,” Kimberly-Clark’s deputy general counsel Kyle Kappes said in a YouTube video.

The company also set up a website to explain its position, called “Safe to Flush.”

D.C.’s law cites the definition of flushable based off international wastewater coalition standards. Without clear labeling, Cheh said, there is consumer confusion over what can and cannot go down the toilet.
