The ECCN is a five-character code, and each character carries meaning. The first digit is the category, from 0 to 9: 0 is nuclear, 1 is materials and chemicals, 2 is materials processing, 3 is electronics, 4 is computers, 5 is telecommunications and information security, 6 is lasers and sensors, 7 is navigation and avionics, 8 is marine, and 9 is aerospace and propulsion.
The letter is the group: A is equipment, assemblies, and components, B is test, inspection, and production equipment, C is materials, D is software, and E is technology. The last three digits are the reason for control: 000 to 099 is national security, 100 to 199 is missile technology, 200 to 299 is nuclear nonproliferation, 300 to 399 is chemical and biological, and 900 to 999 is anti-terrorism or regional stability.
The list lives in Supplement No. 1 to Part 774 of the Export Administration Regulations, and it is administered by the Bureau of Industry and Security under the Export Control Reform Act of 2018. The ECCN is the classification, and the licence decision follows from it, the destination, and the end user.
The first path is to ask the manufacturer. The manufacturer knows the item's design and its intended use, and the manufacturer is the one who classified it when it was built. A manufacturer who will not give the ECCN is a manufacturer who has not classified the item, and that is a reason to ask twice.
The second path is to self-classify. The exporter reads the Commerce Control List, finds the entry that describes the item, and assigns the ECCN. The self-classification has to be documented, because the exporter is the one who stands behind it, and the documentation is the evidence that the classification was reasoned, not guessed.
The third path is to ask BIS for a classification. The Bureau will issue a formal classification on request, and the request is the safest route for an item that sits on the line between two entries. The request takes time, and the shipment waits, but a wrong self-classification costs more than the wait.
EAR99 is the designation for an item that is subject to the Export Administration Regulations but has no entry on the Commerce Control List. Most commercial goods are EAR99, and most EAR99 shipments need no licence. The designation is not a free pass. It is a classification that says the item is controlled by the regulations but not by a list entry, and the licence requirement is decided by the destination and the end use, not by the absence of a code.
The narrow cases that need a licence for EAR99 are the ones the regulations name: a sanctioned destination, a prohibited end user, a prohibited end use such as a weapons program, and a destination under an embargo. A shipment of EAR99 goods to a listed entity needs a licence, and the licence is refused more often than it is granted.
ITAR items are a different system entirely. Items on the US Munitions List are controlled under the International Traffic in Arms Regulations, not the EAR, and they get no ECCN. An item that is ITAR-controlled and shipped as EAR99 is a violation, and the violation is discovered at the border or in the audit. The certificate of origin is the document that says where the goods were made, and the ECCN is the code that says what they are, and the two are asked for on different forms for different reasons.
A five-character code on the Commerce Control List that classifies an item for export control. The first digit is the category, the letter is the group, and the last three digits are the reason for control.
It means the item is subject to the Export Administration Regulations but has no entry on the Commerce Control List. Most commercial goods are EAR99, and most EAR99 shipments need no licence, except for sanctioned destinations, prohibited end users, and prohibited end uses.
Ask the manufacturer, self-classify from the Commerce Control List and document the reasoning, or ask BIS for a formal classification. The manufacturer is the fastest route, and the BIS request is the safest for an item on the line between two entries.
No. Items on the US Munitions List are controlled under the International Traffic in Arms Regulations, not the EAR, and they get no ECCN. Shipping an ITAR item as EAR99 is a violation.
