"Specially designed" is a defined term in § 772.1 of the Export Administration Regulations (EAR). It decides whether a bracket, a circuit board, a seal or a piece of software is controlled along with the item it is used in. Since export control reform the definition has had two steps: paragraph (a) catches an item, and paragraph (b) releases a caught item that meets any one of its criteria (the catch-and-release test).
Where the specially designed definition applies
The phrase appears hundreds of times in the Commerce Control List (CCL). Many entries control "parts, components, accessories and attachments specially designed" for a controlled item. Every 600 series entry has a .x paragraph built on it. Read too broadly, the term controls everyday hardware. Read too narrowly, it lets controlled parts out without a licence. The definition in § 772.1 gives a repeatable answer, and you apply it inside a specific entry once you know which paragraph uses the term (see how to read an ECCN entry).
Step 1: the catch in § 772.1 paragraph (a)
An item is caught if either of these is true:
- Under (a)(1), as a result of development, the item has properties peculiarly responsible for achieving or exceeding the controlled performance levels, characteristics or functions described in the relevant entry.
- Under (a)(2), the item is a part, component, accessory, attachment or software for use in or with a commodity or defense article enumerated or otherwise described on the CCL or the USML.
Paragraph (a)(2) is broad. Most parts made for a controlled item are caught at this step, which is why the release step decides so many classifications. Accessories and attachments are caught the same way: a mount or case made for one controlled camera is caught under (a)(2) unless a release applies.
Step 2: the release in paragraph (b)
A caught item is released if it meets any one of the criteria in paragraph (b). In outline, the item is released if:
- it has been identified as not specially designed in a formal classification or jurisdiction determination;
- it is, regardless of form or fit, a fastener, washer, spacer, insulator, grommet, bushing, spring, wire or solder;
- it has the same function, performance capabilities and form and fit as a part in production that is not controlled on the CCL, or only for anti-terrorism reasons, or is EAR99;
- it was or is being developed with knowledge that it would be for both controlled and uncontrolled items;
- it was developed as a general-purpose item;
- it was or is being developed with knowledge that it would be for items that are not controlled (with documentation to show it).
Paragraph (b) has conditions and notes of its own. The "in production" comparison, for example, has requirements about what counts as production, and it needs a real, comparable item that is in production. A hypothetical one does not qualify. Read paragraph (b) in full in the EAR on eCFR before relying on a release.
Records for releases based on development knowledge
Several releases turn on knowledge at the time of development. If a release is ever questioned, the support for it is the design records, specifications and requirement documents that show the item was developed for general or civil use. Attach that evidence (requirement documents, design reviews, customer specifications) to the classification record when you rely on one of these releases. A release without records behind it is hard to defend.
Worked examples of catch and release
| Item | Paragraph (a) | Paragraph (b) | Outcome |
|---|---|---|---|
| A standard stainless screw used in a military aircraft | Caught by (a)(2) | Released as a fastener | Not 9A610.x |
| A custom machined bracket made to a drawing for one military aircraft, with no civil counterpart | Caught by (a)(2) | No release applies | 9A610.x |
| A connector designed for a military radio, identical in form, fit, function and performance to a commercial connector in production that is EAR99 | Caught | Released by the production-equivalent criterion | Released |
| A cooling unit designed with knowledge it would be used in both a controlled infrared camera and a civil one | Caught | Released as developed for both | Released |
Released is not the same as uncontrolled. A released part leaves the entry that caught it and then needs its own classification, often a 9xx entry or EAR99.
How to apply the definition in a classification
- Find the candidate entry and the paragraph that uses "specially designed" for this item.
- Check whether the item is enumerated in a paragraph. If the paragraph only catches it as a part, component, accessory, attachment or software "specially designed" for something, go on to the next step.
- Decide whether the item is caught under (a)(1) or (a)(2).
- Work out which release in paragraph (b) could apply, and whether the facts support it.
- Where the release needs knowledge at the time of development, check that the documentation exists and is on file.
- Record which release, if any, you relied on.
- If the item is released, find its own classification.
Common mistakes with specially designed
These come up again and again in parts and components work:
- Stopping after the catch without testing the releases.
- Applying a release without the records to back it.
- Using the EAR definition for an ITAR analysis, or the reverse. The ITAR has its own definition in § 120.41, which follows the same structure adapted to defense articles. Use the definition of the regulation you are applying (the ITAR vs EAR jurisdiction guide covers which one that is).
- Forgetting that "specially designed" also applies to software. Software specially designed for controlled items is caught in the same way and can be released in the same way.

"Specially designed" in ECCN.help
When a candidate entry turns on "specially designed", the ECCN.help Classification Workflow asks the catch and release questions one at a time and records each answer. The result shows which paragraph of § 772.1 decided it. The workflow is rule-based, with no AI.
