The DDTC conducts enforcement proceedings for violations of the Arms Export Control Act (AECA) and the International Traffic in Arms Regulations (ITAR). The DDTC maintains, technically, two separate lists of debarred individuals: a statutory debarrment list, and an administrative debarrment list. If you get convicted of violating AECA, you end up on the first list. If the enforcement action doesn't get to a conviction (e.g. you agree to a settlement, much like OFAC's enforcement actions generally do), you end up on the 2nd list. The administrative debarrment list is currently tiny – 3 listings. If you are statutorily debarred, you have to apply to be reinstated. Debarrments and reinstatements are listed in the Federal Register.
So, what does debarrment mean? From the DDTC website:
these persons are prohibited from participating directly or indirectly in the export of defense articles (including technical data) and defense services.
Also on the DDTC website are the list of restrictions by country, a list of consent agreements (there were 3 in 2013, including one with Raytheon), and a summary of enforcement actions over the last 6 years. A quick perusal of that second document shows that violators go to jail – in stark contrast with OFAC and other sanctions regimes.
