Military and aerospace items will need export licensing under International Traffic in Arms Regulations (ITAR) enforced by the U.S. government’s Directorate of Defense Trade Controls (DDTC). Dual-use goods, which can have both military and civilian applications, require an Export Control Classification Number (ECCN) according to the Bureau of Industry and Security (BIS) Export Administration Regulations (EAR). Even if your goods aren’t controlled under ITAR and don’t have a specific ECCN classification under the EAR, instead falling into the generic EAR99 category, all exports are still subject to Office of Foreign Assets Control (OFAC) regulations; these enforce export laws regarding various country-specific boycotts and embargoes, and regulate all international financial transactions, prohibiting dealings with certain specified entities, foreign nationals, governments, and other Specially Designated Nationals.
