In the U.S., many items are controlled, meaning the national government has an interest in where they go, to whom and for what purpose. Just because they are controlled does not mean that an export license is required. Controlled items are assigned an export control number. You can visit this website, https://www.bis.doc.gov/index.php/licensing/commerce-control-list-classification enter information about your product and search for the control number. Generally, products used in making chemical or nuclear weapons require special permission from the government before they can be exported, and there may be other restrictions as well, such as avionics used in weapons systems. But avionics can be used in non-military products too, so the “who” question becomes important.
