600 Series ECCNs Explained | Shipping Solutions

If your company manufactures, exports or brokers military-related or dual-use items, you’ve likely encountered the term 600 series ECCN.

A 600 series Export Control Classification Number (ECCN) is part of the Export Administration Regulations (EAR) and identifies defense-related items that were formerly controlled under the International Traffic in Arms Regulations (ITAR) on the United States Munitions List (USML). As part of the U.S. government’s Export Control Reform initiative, these items were transferred to the Commerce Control List (CCL) and are now administered by the Department of Commerce’s Bureau of Industry and Security (BIS).

Quick Definition

A 600 series ECCN is an Export Control Classification Number under the EAR identifying former USML military or defense-related items that are now controlled by the Commerce Department. These items typically require export licenses to most countries and are subject to stricter controls than standard dual-use ECCNs.

Although these items are no longer regulated under ITAR, that does not mean they are easy to export. In fact, many 600 series items remain tightly controlled and often require export licenses for most destinations.

Understanding whether a product falls into the 600 series—and what that classification means for licensing and compliance—is an important part of maintaining an effective export compliance program.

Why the 600 Series Exists

The first 600 series ECCNs were introduced in 2013 as part of the U.S. government’s Export Control Reform (ECR) initiative. The goal of this reform effort was to better distinguish between items that provide a critical military advantage and those that have legitimate commercial or dual-use applications.

Items that provide a uniquely military or intelligence advantage remain controlled under ITAR and the USML. However, many other defense-related products—particularly components, parts and related technology—were determined to be more appropriately controlled under the EAR.

Those items were transferred from the USML to the Commerce Control List and assigned new ECCNs within what became known as the 600 series. Many of these items also correspond to categories within the Wassenaar Arrangement Munitions List, which helps align U.S. export controls with international export control regimes.

Although the EAR generally offers more licensing flexibility than ITAR, 600 series items are still considered sensitive. As a result, they are often subject to stricter requirements than standard dual-use items on the CCL.

Why 600 Series ECCNs Still Create Confusion

More than a decade after their introduction, 600 series ECCNs continue to create confusion for many exporters. Companies in industries such as aerospace manufacturing, defense contracting, electronics production and engineering services frequently encounter these classifications when dealing with military-adjacent products or technical data.

Part of the challenge is that 600 series items sit between two regulatory frameworks. They are no longer ITAR-controlled defense articles, yet they are still more tightly regulated than most dual-use products under the EAR.

Because of this middle ground, exporters sometimes assume that items moved off the USML became easier to export. In reality, the compliance requirements remain significant. Many 600 series items require export licenses for most destinations outside Canada, and exporters must carefully evaluate licensing requirements, restricted party screening and documentation obligations before shipping.

How to Identify a 600 Series ECCN

Understanding whether your item falls into the 600 series starts with recognizing how Export Control Classification Numbers (ECCNs) are structured under the Export Administration Regulations (EAR).

600 Series ECCN Format

A 600 series ECCN follows this format:

xY6zz

Here’s what each part means:

Element What It Represents Example (5A611)
x CCL Category (0–9) 5 (Telecommunications & Information Security)
Y Product Group (A–E) A (Systems, Equipment & Components)
6 Indicates 600 Series classification 6
zz Specific entry identifier 11

So, 5A611 is a 600 series ECCN because the third character from the end is a “6.”

Licensing & Compliance Requirements for 600 Series Items

Although 600 series items are controlled under the EAR rather than ITAR, they remain subject to strict licensing requirements.

Most 600 series ECCNs are controlled for:

  • NS1 (National Security Column 1)
  • RS1 (Regional Stability Column 1)
  • AT1 (Anti-Terrorism Column 1)

Because NS1 controls trigger licensing requirements for most destinations on the Commerce Country Chart, licenses are typically required for exports outside Canada. Exporters must cross-reference the ECCN’s reasons for control with the Commerce Country Chart (EAR Part 738).

Military End-Use & End-User
In addition to Country Chart analysis, 600 series items are specifically identified in Part 744 military end-use and end-user restrictions. This means a license may be required based on the identity of the end user or the intended military application—even when traditional reasons-for-control analysis would not independently trigger one.

In addition to country-based licensing requirements, exporters must also evaluate end users and end uses. Certain military end-use or military end-user restrictions in EAR Part 744 may apply to 600 series items, potentially requiring a license even when the Commerce Country Chart would not otherwise trigger one.

Another important requirement involves export reporting. Unlike many dual-use exports, all shipments of 600 series items require Electronic Export Information (EEI) to be filed through the Automated Export System (AES), regardless of the value of the shipment or the destination country.

Exporters must also be aware that 600 series items may not be exported, reexported or transferred to countries subject to U.S. arms embargoes under EAR Part 746.

This video walks you through the procedures you need to follow to determine if your exports require a license:

Deemed Exports of 600 Series Technology

Compliance obligations extend beyond physical shipments.

A deemed export occurs when a U.S. company releases knowledge of controlled technology to a foreign national. Unlike exports of physical goods, a deemed export represents the transmission of information itself.

“Use” technology refers to specific information necessary for the use of a product subject to a technology-related ECCN.

Regarding deemed exports of 600 series items, a license is required for deemed exports of “Use” technology when the following conditions are met:

  1. Technology pertaining to one or more of the elements of “Use” listed in a 600 series ECCN will be released;
  2. The technology is not publicly available;
  3. The individual to whom it is released is a foreign national; AND
  4. A license is required to export the “Use” technology to the individual’s home country.

600 Series vs. 9x515 ECCNs

Another group of former ITAR items moved to the EAR is the 9x515 series, which covers certain spacecraft and related items formerly listed under USML Category XV.

Examples include:

  • 9A515: Spacecraft and related commodities
  • 9D515: Software
  • 9E515: Technology

All technology-related ECCNs use “and” language with the exception of 600 series ECCNs and 9x515 ECCNs, which use “or.”

For example, 9E915 (a 9x515 ECCN) reads as follows:

“Technology” “required” for the “development,” “production,” operation, installation, repair, overhaul, or refurbishing of “spacecraft” and related commodities, as follows (see List of Items Controlled).

Aside from these two groups, technology ECCNs use “and” instead of “or.” Thus 600 series and 9x515 technology ECCNs are broader in scope than other technology ECCNs, encompassing a much wider range of technologies. And just like 600 series ECCNs, exporters must maintain oversight on deemed exports of 9x515 technology.

Strengthening Your 600 Series Compliance Program

Managing 600 series ECCNs requires structured processes that address:

  • Product classification
  • License determination
  • AES filing
  • Restricted party screening
  • Documentation retention

Trying to manage these responsibilities with spreadsheets or disconnected systems can create unnecessary risk—especially when dealing with items that were once controlled under ITAR. Even small mistakes can lead to shipment delays, compliance violations or enforcement scrutiny.

Many exporters rely on compliance software to bring these processes together in a single system.
