Export Control and Machined Parts: ECCN, EAR99 and Deemed Export
A purchase order arrives with a note in the drawing block: "Export controlled — do not release technical data to foreign nationals." Or the RFQ asks, innocently, "Please confirm the ECCN for this part." Both put a machine shop in a position it is not naturally equipped for: making a legal determination about a product it did not design, for a destination it may not know.
There is a correct way to handle it, and it mostly involves knowing what you can say, what you must not say, and who owns the decision. This is written from the supplier's side and is deliberately cautious: classification is fact-specific, and nothing here substitutes for advice on your own item.
The ECCN in five characters
The Export Administration Regulations maintain the Commerce Control List. Each entry has an Export Control Classification Number built from three parts:
- Category (first digit, 0-9). For example 2 is materials processing, which is where machine tools sit.
- Product group (letter). A for systems and equipment, B for test and production equipment, C for materials, D for software, E for technology. A machined component is usually a material or a part, not a machine.
- Three digits. Sequential within the category and group.
So 2B001 is a machine tool entry. The number tells you where to look, not whether your item is caught. The entry contains technical parameters — accuracy, axes, control resolution — and your item is controlled only if it meets them.
Two points matter for machined parts. The CCL controls items by their own characteristics, and a plain metal bracket is rarely described by any entry. But the concept of "specially designed" pulls in parts designed for a controlled item even when the part looks ordinary — and that analysis depends on the end item, which the shop usually cannot see.
What EAR99 actually means
EAR99 is not a classification of "harmless". It means the item is subject to the EAR but is not described by any ECCN on the Commerce Control List.
An EAR99 item can still require a licence. End-use and end-user controls apply regardless of the ECCN: if the item is destined for a prohibited end use, a restricted party or an embargoed destination, EAR99 status does not help.
EAR99 is the answer most commercial machined parts would receive, and it is also one a shop is poorly placed to give, because it requires knowing the full specification and the end item. A supplier who writes "EAR99" on a shipping document without a basis has made a consequential statement about someone else's export.

Deemed export, and why the drawing matters more than the part
A deemed export is the release of controlled technology or source code to a foreign national inside your own country. It is treated as an export to that person's country of nationality or permanent residence.
For a machine shop this is the most immediate risk, and it is invisible in the shipping paperwork: if a customer sends a package marked as controlled technology and a foreign national programmer reads it, a deemed export may have occurred.
Three consequences follow:
- Access control on technical data has to be real. A shared network folder is not access control.
- Marking matters. If a customer sends controlled data unmarked, you cannot manage what you do not know about — ask in writing for the classification at RFQ stage.
- ITAR is a separate regime. A shop not registered with the US State Department should not accept ITAR technical data at all, and should say so before the file is opened.
If a customer will not state the classification, treat that as unresolved rather than an invitation to assume.
Scenarios and likely treatment
The table below is illustrative only. Each row depends on facts the shop does not control, and the classification belongs to the item's designer or exporter.
| Scenario | Likely treatment | Why it depends on classification |
|---|---|---|
| Standard aluminium bracket, no controlled features | Probably not on the CCL; EAR99 likely | Only the designer knows the end item and whether "specially designed" applies |
| Part for a machine tool with sub-10 µm positioning accuracy | Part itself usually uncontrolled; the machine is controlled | Controls sit on the machine's parameters, not on a bracket bolted to it |
| Component designed solely for a controlled radar or UAV system | May be caught as specially designed | Requires knowledge of the end item and the design intent |
| Part with a customer drawing marked "ITAR" | Do not accept without a compliant process | ITAR technical data requires registration and access controls most shops lack |
| Drawing package accessed by a foreign national employee | Possible deemed export | Depends on the controlled status of the technical data and the person's status |
| Item destined for a restricted party or prohibited end use | Licence required regardless of ECCN | End-use and end-user controls apply to EAR99 items too |
| Shop asked to sign "ECCN: EAR99" on a commercial invoice | Only if the shop is the exporter of record and has a basis | Otherwise the exporter of record owns the determination |
The last row is where disputes start. A supplier is often asked to state a classification on documentation it signs, for a shipment it does not control. Clarify who the exporter of record is before signing anything.
What a shop should and should not answer
A machine shop can reasonably provide:
- A factual description of the part: material, dimensions, tolerances, finish, function as drawn.
- Confirmation that it holds no technical data beyond the drawing supplied.
- The manufacturing process and equipment used, where that equipment is not itself controlled.
- Where the part was manufactured.
A machine shop should not:
- Assign an ECCN to a customer's design.
- Confirm EAR99 status without a documented basis and the customer's classification.
- Opine on whether a licence is required for a destination it was not told about.
- Accept controlled technical data without the required access controls.
- Answer end-use questions on the customer's behalf.
The useful response to "what is the ECCN?" is a polite redirect: the classification belongs to the item's designer or exporter of record, and you can confirm the manufacturing facts. Most compliance teams accept that, because they know it is true.
Where the shop exports directly rather than selling to a domestic distributor, the shop may be the exporter of record — get proper advice. Our shipments go to the US, Canada, Germany, the Netherlands, UK and Sweden, and we confirm the manufacturing facts while the customer owns the classification.
For how we receive and handle drawings, see how we work — drawing handling, access control and retention are described there, which is usually what a compliance team wants before releasing a package. The EAR generally requires export records to be kept for five years from the date of export; your own retention should not be shorter.
Frequently asked questions
Does a machined part need an ECCN?
Most commercial machined parts are not described by any ECCN and are therefore EAR99, but that is a conclusion about a specific item, not a default. Parts designed for a controlled end item can be caught through the specially designed rules, and some materials are themselves controlled.
Can we just say EAR99 on our paperwork to keep things moving?
Only if you are the exporter of record and have a documented basis. Putting EAR99 on a document you sign shifts responsibility onto you if the item turns out to be controlled.
What should we do if a customer sends ITAR-marked drawings?
Stop before opening them and check with your compliance lead. ITAR technical data handling generally requires registration and specific access controls, and the consequences of unauthorised access are severe. Many shops outside the US decline ITAR work for this reason, and it is reasonable to say so early.
Is deemed export relevant if all our staff are local nationals?
It depends on nationality and immigration status; a permanent resident and a citizen are treated differently from a foreign national. If you handle controlled technical data, keep an access list by person and review it at each staffing change.
