Walmart is opening its doors to more than 450 entrepreneurs today, June 28, during the company’s Made in the U.S.A. open call event for products made, assembled or grown in the U.S.

The open call is part of Walmart’s fourth annual U.S. Manufacturing Summit, hosted at the company’s headquarters in Bentonville, AR.

The retailer said that hundreds of potential and current suppliers are pitching everything from food to toys to apparel, and meeting with buyers for the chance to sell their U.S.-made products at Walmart. In addition, the retailer said it is putting every shelf-stable item pitched at open call today on Walmart.com.

“We are thrilled to put hundreds of new Made in the U.S.A. products on Walmart.com,” said Michelle Gloeckler, evp/consumables, health and wellness, U.S. manufacturing lead. “Walmart’s $250 billion commitment to buy products supporting American jobs is having a tangible impact on communities across the country as factories expand or open to make products for Walmart stores, Walmart.com and Sam’s Club.”
