Amazon.com Inc. is being investigated by federal authorities for delivering approximately $24,700 worth of products to an Iranian embassy, "located in a country other than Iran," according to a filing the company made with the Securities and Exchange Commission on July 28.

The e-commerce giant said it delivered about $8,100 worth of products to "individuals who may have been acting for five Iranian embassies located in countries other than Iran," as well as approximately $600 to people who may have been working for entities controlled by the Iranian government. The company also noted that it sold about about $300 to an individual designated under "Executive Order 13224." The executive order, introduced by President George Bush in 2001, blocks transactions with "persons who commit, threaten to commit, or support terrorism."

The products Amazon sold to these individuals included books, apparel, jewelry, consumer electronics and musical instruments, according to the filing.

"We are unable accurately to calculate the net profit attributable to these transactions," the company said in the filing. "We do not plan to continue selling to these accounts in the future."
