WASHINGTON (Reuters) - Luxury kitchenware company Williams-Sonoma Inc WSM.N and its Pottery Barn unit have agreed to stop making unsubstantiated "made in America" claims and to pay $1 million, the Federal Trade Commission said on Monday.

The FTC, which investigates companies that make deceptive claims, said Williams-Sonoma had said that its Goldtouch Bakeware, Rejuvenation products and some Pottery Barn Teen and Kids furniture were made entirely in the United States.

In fact, the FTC said, the products were made outside the United States or contained significant imported elements.

Williams-Sonoma will pay a $1 million fine, the FTC said.

The company did not immediately respond to a request for comment.
