The export-control warning on technical data: what it says and where it comes from

The wording of the DoD export-control warning, the instruction that requires it, the two export regimes it points to, and how it travels with a distribution statement.

Why it matters

The warning marks technical data whose export is restricted by law, and it always travels with a distribution statement B, C, D, or E.

The short version

  1. 1The 2023 warning names the Export Control Reform Act of 2018 as its second statute; the 2012 wording named the Export Administration Act of 1979.
  2. 2Information found to contain export-controlled technical information gets the warning plus Statement B, C, D, or E, with export control as a reason.
  3. 3Statement C or D export-controlled information is not distributed outside the Government or to contractors without verifying a current DD Form 2345.

A Department of Defense (DoD) technical document that carries the export-control warning is stating that it contains technical data whose export is restricted by law. A program office, a contractor, or a maintainer who holds such a document reads the warning as the marking that points to the rules for disseminating it. DoD Instruction (DoDI) 5230.24, reissued on January 10, 2023, requires the warning, and the warning points to two statutes: the Arms Export Control Act and the Export Control Reform Act of 2018.

The warning, as the current instruction prints it
WARNING - This document contains technical data whose export is restricted by the Arms Export Control Act (Section 2751 of Title 22, United States Code) or the Export Control Reform Act of 2018 (Chapter 58 Sections 4801-4852 of Title 50, United States Code). Violations of these export laws are subject to severe criminal penalties. Disseminate in accordance with provisions of DoD Directive 5230.25 and DoD Instruction 2040.02.

What the warning says

The instruction prints the warning as Figure 3. It makes three statements:

  1. The document contains technical data whose export is restricted by the Arms Export Control Act (Section 2751 of Title 22, United States Code) or the Export Control Reform Act of 2018 (Sections 4801-4852 of Title 50).
  2. Violations of these export laws are subject to severe criminal penalties.
  3. The document is to be disseminated in accordance with DoD Directive 5230.25 and DoD Instruction 2040.02.

Paragraph 4.3.e.(2) sets the scope. All printed and electronic technical information, including information in digital form, that is determined to contain export-controlled technical information is marked this way. When using the entire statement is technically impractical, an abbreviated marking may be used, with the full statement added to the notice that accompanies release of export-controlled technical information.

The 2012 wording is still in circulation

The 2023 instruction replaced a version dated August 23, 2012. The earlier warning named a different second statute. The Defense Logistics Agency's ASSIST help page, which still describes the 2012 version, gives it as the Export Administration Act of 1979 and names only DoD Directive 5230.25 for dissemination.

A document library built up over years will therefore hold both forms. A warning that cites the 1979 Act is the earlier form of the same marking, applied under the instruction in force when the document was marked.

How the warning travels with a distribution statement

The warning never stands alone. Under paragraph 3.4, information found to contain export-controlled technical information is marked with the warning and must also be assigned Distribution Statement B, C, D, or E, with "Export Controlled" given as a reason. It must also carry the notice to accompany release of export-controlled data described in DoD Directive 5230.25, and it is released only to entities qualified to receive it.

Three related rules sit beside that one:

  • Statement A is excluded. The instruction says the public release statement will not be used on information containing export-controlled technical information.
  • Statement X is gone. The instruction cancels the former Distribution Statement X and says information that carried it is now shown with Distribution Statement C, with export control as the stated reason.
  • Recipients are verified. Export-controlled technical information marked with Statement C or D is not distributed outside the U.S. Government, or to government contractors, without first verifying that the recipient holds a current DD Form 2345, the Militarily Critical Technical Data Agreement.

The instruction places the decision with the controlling DoD office. For new, revised, or previously unmarked technical information, that office determines whether export-controlled technical information is present, using DoD Directive 5230.25 and the two export regimes as guidance.

The two regimes behind the warning

The instruction defines export control in terms of two sets of regulations. Defense articles, defense services, and related technical data are subject to the International Traffic in Arms Regulations (ITAR), Parts 120 through 130 of Title 22 of the Code of Federal Regulations (CFR). Commodities, software, and technology are subject to the Export Administration Regulations (EAR), Parts 730 through 774 of Title 15.

The ITAR. Under 22 CFR 120.1, Section 38 of the Arms Export Control Act authorizes the President to control the export and import of defense articles and defense services. That authority is delegated to the Secretary of State, and the regulations are administered by the Directorate of Defense Trade Controls.

The EAR. 15 CFR Part 730 says the EAR govern certain exports, reexports, and related activities, and that the Department of Commerce's Bureau of Industry and Security issues and administers them. The part's authority citation begins with Sections 4801-4852 of Title 50, the same range the warning cites for the Export Control Reform Act of 2018.

DoD contracts name both regimes. Defense Federal Acquisition Regulation Supplement (DFARS) clause 252.225-7048 defines export-controlled items as items subject to the EAR or the ITAR. Paragraph (b) requires the contractor to comply with all applicable laws and regulations on export-controlled items, including the requirement to register with the Department of State in accordance with the ITAR. The clause refers questions about ITAR compliance to the Department of State and questions about EAR compliance to the Department of Commerce.

What to check

  • Does the warning cite the Arms Export Control Act and the Export Control Reform Act of 2018, or the Export Administration Act of 1979? The first marks the 2023 instruction, the second the 2012 version.
  • Is Distribution Statement B, C, D, or E on the document, with export control given as a reason?
  • Is Statement A on a document that contains export-controlled technical information? The instruction says it will not be used.
  • If the warning is abbreviated, does the notice that accompanies release carry the full statement?
  • For Statement C or D, has the recipient's current DD Form 2345 been verified before the information goes outside the Government or to contractors?

Azcuna's TRACE is one offline viewer for S1000D, MIL-STD-3001 XML, and PDF technical manuals. It keeps the source location and the markings of everything it shows and never modifies the source. It was proposed to NAVAIR under Navy SBIR Phase I topic DON26BZ05-NV078, and the proposal was submitted on September 23, 2026.
