Check the packaging. While it's permissible to bring in some types of frozen food from certain countries, if the food isn't completely frozen and there is liquid present in the container when it arrives in the U.S., it will likely be denied at customs.
Fill in the customs declaration properly. Put an X in the "Yes" box under bullet 11. Mark "a" if your frozen food contains fruits, plants, food, or insects, "b" if it contains meats, animals, or animal/wildlife products, and "c" if it contains snails. Sign the form.
Approach the U.S. Customs officer. These officers are generally located after passport control in most major airports and receive customs declarations from travelers.
Present the customs declaration. Notify the customs officer that you are bringing in frozen foods.
Follow the customs officer to the inspection desk, if required.
Open the container and present the frozen food when requested by the customs officer. If requested, show proof of origin.
Receive permission to bring the frozen food into the U.S.
