While Aptamil is little known in the United States, it is a major brand in Europe, where Danone is a dominant force in the market. The move to introduce Aptamil to American parents could give Danone, a relatively small U.S. player, the opportunity to grab share from market leaders Reckitt and Abbott Laboratories.

The additional 550,000 Aptamil cans that are en route from New Zealand will likely be available starting August, while the initial shipments are already on shelves and online at Walgreens, Safeway and some other stores.

Danone also said it had imported more than 500,000 cans of Neocate, a specialized medical baby formula.

Abbott recalled dozens of brands of baby formula in February, sparking one of the biggest food shortages in recent American history. Since then, the U.S. government and Food and Drug Administration have made it easier for manufacturers to get shipments into the country, and appealed to companies from Nestle to Reckitt to step up production.
