Ten shipments were confiscated at the ports of Chicago, Dallas, Los Angeles, Norfolk, Virginia, Memphis, Tennessee, Newark, New Jersey, Portland, Oregon, and Savannah, Georgia.
The shipments were targeted beginning in April when it was found that the dolls contained high levels of phthalates, a group of banned chemical compounds.
Authorities say the shipments were seized since they presented a safety threat to the American public, particularly children, and contained items prohibited in the United States.
