Items prohibited from entry into the United States include the following:
- Liquor-filled candy (where prohibited by state law)
- Lottery tickets
- Narcotics and dangerous drugs,
- Obscene articles and publications
- Seditious and treasonable materials
- Hazardous articles (such as fireworks, dangerous toys, and toxic or poisonous substances)
- Switchblade knives (with the exception of those carried by one-armed persons for personal use)
People attempting to import any prohibited items into the U.S. will be subject to a personal penalty, and the items will be seized.
The U.S. also prohibits the importation of certain wildlife products, including ivory products (except antiques at least 100 years old), sea turtle products (including tortoiseshell items), and items made from endangered or threatened animals such as cheetahs, jaguars, and tigers.
Other wildlife products, including those from various marine mammals, may not be imported in most instances except by special permit from either the U.S. Fish and Wildlife Service or the National Marine Fisheries Service.
The U.S. and more than 130 other countries have signed CITES, a comprehensive wildlife treaty regulating the import or export of endangered and threatened plant and animal species. It is important that you determine any U.S. guidelines governing the importation of products made from endangered or threatened wildlife well in advance of your departure. Although items made from these animals might be on sale in many countries, they may not be permitted into the U.S.
Further, individual U.S. states may have further restrictions or prohibitions. Therefore, you should contact the department governing wildlife in your destination state, also. Items that may be allowed under federal law could be prohibited by your destination state.
Other items are not prohibited outright, but they may be subject to restrictions. Restricted items include the following.
Any type of organism used for education or research must be accompanied by an import permit, typically issued by the U.S. Department of Agriculture.
Latin American cultural property
Some Latin American countries require that an export certificate accompany any pre-Columbian artifacts shipped directly or indirectly to the United States. The U.S. Customs Service enforces this requirement.
“Pirated" copies of copyrighted books
This restriction includes any unauthorized copies of American books. The practice of producing photo-offset copies and selling the books at enormously reduced rates is common in the Far East.
Merchandise originating in certain countries
This restriction includes items from the following countries: Angola, Cuba, Iran, Iraq, Libya, Myanmar (formerly Burma), North Korea, Sudan, the territory of Afghanistan controlled by the Taliban, and the former Yugoslavia.
A U.S. Treasury license issued under the Foreign Assets Control Regulations might be required in order to import certain or all goods (including motor vehicles) from any of the above-mentioned countries, with the exception of informational materials. However, such licenses rarely are granted.

People entering the United States are permitted to bring only a certain number of trademarked items, as set by the trademark holders, into the country every 30 days.
