Scientific, technical, or engineering information can include information for which a data type identifier, such as an export control classification, would indicate that the information should not be published freely and openly with broad distribution. The best source of an export control classification for an item is the originator (manufacturer, vendor, supplier, producer). If a document is unmarked, contact the originator to request the export control classification and ensure that the document is marked moving forward.
Typically, marking occurs in accordance with the U.S. Government’s CUI Marking Handbook. When a document may be published freely and openly with broad distribution, identify this by marking on a cover page, banner, header, or footer that the document does not include any controlled or proprietary information (e.g., unclassified unlimited release, approved for public release). Markings provide clarity and confidence when storing or sharing, and help to avoid needless re-reviews of the information in the future.
Considerations when Marking
- Does the item include any controlled or proprietary information?
- Does the item include any proprietary and non-public information provided by an external party?
- Does the item include any research results subject to a publication or dissemination restriction?
- Does the item include any information subject to an export control regulation?
- Does the item include any Controlled Unclassified Information?
- Does the item include any Covered Defense Information?
