In every AES filing for a United States Munitions List item, the DDTC Quantity and Unit of Measure fields have to match the approved export license exactly. The quantity is the numerical count or weight of the defense articles moving on that shipment; the unit of measure code tells Customs and Border Protection what you counted — pieces, kilograms, liters, or another value from the recognized list. Both are validated in real time against the license balance the moment you submit, and both are among the most common sources of rejected filings.
What the Two Fields Are
Every AES filing for a USML item requires eight defense-specific data elements on top of the standard export data.1U.S. Census Bureau. AES Mandatory Filing Frequently Asked Questions – USML Data Elements Two of them are the DDTC Quantity and the DDTC Unit of Measure Code. The Census Bureau defines the quantity simply as the “number of units that correspond to the DDTC measure reported for this commodity.” Together, the pair lets the government track how much of a licensed defense article has left the country and how much authorization remains.
These two fields are where most filing errors happen, because they force the exporter to reconcile the license against the shipment. The license controls; the packing list does not.
Entering the Quantity
The DDTC Quantity is a precise physical count or weight of what is in the container, and it cannot exceed the remaining balance on the license. Every application field must be completed with actual information — partial entries, “Not Applicable,” and “See Attached” are all rejected.2eCFR. 22 CFR 123.1 – Requirement for Export or Temporary Import Licenses
Each shipment against a license decrements the remaining authorized quantity automatically. If your license covers 500 units and you have shipped 480, a filing for 25 will bounce because it exceeds the 20 remaining. For temporary exports moving between authorized destinations, both the outbound and inbound temporary licenses are decremented so the system can track the hardware’s location.3eCFR. 22 CFR 123.22 – Filing, Retention, and Return of Export Licenses and Filing of Export Information There is no manual override at the port. A quantity that does not clear the check means the cargo sits until you correct and resubmit.
Intangible Exports
Technical data and software transfers still require a numerical entry in the quantity field. No published guidance sets a universal placeholder for intangibles. If your license states a quantity for the technical data package, use that. When it is not obvious, call DDTC at 202-663-2700 before filing rather than guessing.
Selecting the Right Unit of Measure Code
The DDTC Unit of Measure Code has to match the unit stated on your license. CBP publishes the recognized codes in ACE Appendix W, a downloadable reference from the CBP website.4U.S. Customs and Border Protection. ACE Appendix W – DDTC Unit of Measure Codes EA (each) covers individual items, KG covers kilograms, LT covers liters. When the commodity itself is the unit — four jet engines, eleven rifles — codes like “Items” or “Pieces” are appropriate.1U.S. Census Bureau. AES Mandatory Filing Frequently Asked Questions – USML Data Elements
Most mismatches come from commercial shipping documents using a different measurement than the license. A commercial invoice might list ammunition in rounds while the license specifies kilograms. A warehouse might measure a chemical in gallons while the license authorizes liters. Convert with the precise factor (1 U.S. gallon = 3.7854 liters), not a rounded estimate, and enter the license’s unit. Any discrepancy between the AES code and the license unit generates a fatal error.
Pull the unit of measure directly from the license before entering anything. If the license does not specify a unit because the item is a discrete commodity, pick the code that most naturally describes how you counted it. When the answer is not obvious, calling DDTC beats resubmitting after a rejection.
When the Filing Has to Be In
Defense articles all require predeparture filing; you cannot file after the shipment leaves.5eCFR. 15 CFR 30.4 – Electronic Export Information Filing Procedures The specific windows depend on the mode:3eCFR. 22 CFR 123.22 – Filing, Retention, and Return of Export Licenses and Filing of Export Information
- Air or truck: EEI filed and the Internal Transaction Number received at least 8 hours before departure.
- Sea or rail: EEI filed and the ITN received at least 24 hours before departure.
Quantity and unit of measure need to be settled well before cargo reaches the port. A rejected filing seven hours out on an air shipment leaves almost no time to diagnose the error and refile before the flight leaves.
Other Data to Have Ready
The two fields do not sit in isolation. Before opening AESDirect, pull together the full input set:
- DDTC export license number, assigned by the State Department when the license is approved.2eCFR. 22 CFR 123.1 – Requirement for Export or Temporary Import Licenses
- USML category and subcategory for the article.
- Employer Identification Number for the U.S. principal party in interest.6U.S. Customs and Border Protection. Exporters – Numbers That Can Be Used to Identify an Exporter, Carrier, Freight Forwarder When Filing Electronic Export Information via AES
- Foreign consignee and intermediate consignee names and addresses.
- Country of ultimate destination and port of export.
- License expiration date, plus confirmation that the license has enough remaining quantity and value for this shipment.
If the license has expired or is fully decremented, get a new authorization before filing. Submitting against an exhausted or expired license does not just bounce; it leaves a compliance record that can complicate future applications.
The 10 Percent Value Tolerance Does Not Cover Quantity
The license also carries a monetary cap, and CBP allows a shipment’s total value to run up to 10 percent over the license amount without a new authorization, since prices shift between license approval and shipment.7eCFR. 22 CFR 123.23 – Monetary Value of Shipments Two hard limits override the cushion: the tolerance does not apply if the overage would push the total contract value to $14 million or more for major defense equipment, or $50 million or more for defense articles or services generally.
This tolerance is for money only. If your license authorizes 100 units, shipping 101 is a violation regardless of value.
Submitting and Validating
Once the data is entered in AESDirect or DECCS, the system runs a real-time check against federal databases. If quantity, unit of measure, license number, and the rest all validate, it issues an Internal Transaction Number.8U.S. Census Bureau. Filing in AESDirect – How Do You Find Your Internal Transaction Number The ITN is proof the EEI was accepted; give it to the carrier and put it on the shipping documents. Without it the cargo does not clear.
A mismatch produces a rejection with a specific error code. Common triggers include a quantity above the remaining license balance, a unit code that does not match the license, or a reference to an expired license number. Read the error code before you resubmit. Guessing at the fix and firing off a second wrong value burns the time you need to correct the real problem before the filing window closes.
Fixing Errors After Filing
Mistakes discovered after departure have to be corrected electronically in AES as soon as you become aware of them. Federal regulations require the filer to transmit corrections, cancellations, or amendments as soon as possible, and failing to do so is itself a violation.9eCFR. 15 CFR 30.9 – Transmitting and Correcting Electronic Export Information
When the error rises to an actual ITAR violation, for example a shipment of more units than the license authorized, the recommended path is a voluntary self-disclosure to DDTC. The State Department encourages self-reporting, and a disclosure may be considered a mitigating factor at the penalty stage. The process runs in two stages: an initial written notification to DDTC as soon as the violation is discovered, then a full disclosure within 60 calendar days covering the details of the violation, the USML category and quantity involved, the license numbers at issue, and the corrective steps taken. A senior officer can request a written extension on the full disclosure if 60 days is not enough, but the initial notification still has to go out immediately.10eCFR. 22 CFR 127.12 – Voluntary Disclosures
Do not sit on a known error. DDTC treats self-reported problems very differently from problems it uncovers on its own.
Recordkeeping
Every record tied to a quantity and unit of measure filing — license copies, EEI submissions, shipping documents, correspondence — must be retained for five years from license expiration or from the transaction date, whichever applies.11eCFR. 22 CFR 122.5 – Maintenance of Records by Registrants Licenses that CBP decrements electronically do not need to be returned to DDTC, but a copy has to be kept for the full retention period.3eCFR. 22 CFR 123.22 – Filing, Retention, and Return of Export Licenses and Filing of Export Information DDTC can prescribe a longer or shorter period in individual cases, so specific direction from the agency overrides the default.
Penalties for Getting It Wrong
Civil penalties for each violation of the Arms Export Control Act can reach the greater of $1,271,078 or twice the value of the underlying transaction. Because each unauthorized shipment counts separately, a pattern of incorrect quantity reporting across multiple filings can compound quickly. Civil penalties can also be imposed as a condition for keeping or restoring export privileges.12eCFR. 22 CFR 127.10 – Civil Penalty
Willful violations carry criminal exposure: fines up to $1,000,000 and imprisonment up to 20 years per violation.13eCFR. 22 CFR Part 127 – Violations and Penalties The line between a careless mistake and a willful violation is thinner than many exporters realize. Repeatedly filing incorrect quantities after being warned, or knowingly using the wrong unit of measure to fit within a license balance, can move what began as an administrative error into criminal territory. The practical protection is a second set of eyes: build quantity and unit of measure verification into your compliance procedure so someone other than the filer reviews every entry before it hits AES.
