AES Filing and the ITN, Explained for U.S. Exporters

If you're exporting from the United States, you'll eventually run into three acronyms: AES, EEI, and ITN. They're related parts of the same process — the electronic reporting of export shipments to the U.S. government. Here's a plain-English overview, kept general and conservative, plus how Conveyco coordinates the filing as part of your shipment.

A note on specifics: export reporting rules, thresholds, and exemptions are set by federal regulation and change over time. This article stays general on purpose. For the requirements that apply to your specific shipment, we'll confirm the current rules with you and our customs broker partner before filing.

The short answer

When certain U.S. export shipments move, the exporter (or an authorized agent) must electronically file Electronic Export Information (EEI) through the Automated Export System (AES). Once accepted, the system returns an Internal Transaction Number (ITN) — a confirmation that the filing was made. The ITN typically needs to travel with the shipment's documentation.

What is AES?

The Automated Export System (AES) is the U.S. government's electronic platform for collecting export shipment data. It's the channel through which export information is reported to the relevant federal agencies. Filing "through AES" is how the required export data gets submitted electronically.

What is EEI?

Electronic Export Information (EEI) is the data set that gets filed in AES — details about the exporter, the goods (including their classification), the destination, value, and parties involved. It's the modern electronic replacement for what older exporters may remember as the paper "Shipper's Export Declaration."

What is the ITN?

The Internal Transaction Number (ITN) is the proof of filing. After EEI is submitted and accepted in AES, the system issues this unique number. It generally needs to be referenced on shipping documentation so the carrier and authorities can confirm the export was reported.

When is a filing required?

This is where we stay deliberately general. Whether EEI must be filed depends on factors set by federal regulation — things like the value of the goods by classification, the destination, and whether the commodity requires an export license. There are thresholds and exemptions, and they're updated periodically.

We won't state specific dollar thresholds or exemption rules here, because they change and the details matter. The safe approach is to treat every export as potentially reportable and confirm the actual requirement before the shipment moves. That confirmation is part of what we coordinate.

How Conveyco coordinates the filing

Conveyco supports U.S. exporters with export documentation and booking, and we coordinate the AES/EEI filing as part of your shipment. In practice that means:

• Gathering the data needed for the filing (parties, commodity classification, destination, value).
• Coordinating the EEI submission through AES — working with our licensed customs broker partner where the filing is handled by the broker.
• Making sure the resulting ITN is reflected on the shipping documentation so it travels with the cargo.
• Lining the filing up with the rest of the move — booking, drayage, and vessel cutoffs — so documentation timing doesn't hold up the sailing.

Bottom line

AES is the system, EEI is the data you file, and the ITN is your proof of filing. The exact rules on when a filing is required are governed by federal regulation and shift over time, so the right move is to confirm the current requirements for your specific shipment. Conveyco coordinates that filing alongside the rest of your export.
