ECCN Classification for Tech and Dual-Use Exports

The ECCN is the code that tells you whether your tech hardware needs an export license, where it can go, and who can receive it. For OEMs, distributors, resellers, data center operators, and AI teams that ship across borders, it is the first compliance decision for every shipment.

TL;DR

  • An ECCN is a five-character code on the US Commerce Control List (CCL) that identifies items controlled for export.
  • A combination of the ECCN, destination, end user, and end use determines whether you need a license.
  • Most IT hardware is controlled due to encryption or computing performance.
  • US rules follow US-origin items and technology abroad, so non-US companies are often in scope.
  • Destination countries add their own export, import, and encryption rules on top.

Each piece of hardware or software built that leaves the United States, or contains US-origin technology, carries an export classification. While the Export Control Classification Number (ECCN) is a US code, it is not only for US exports. It also concerns products of US origin for re-export, or any foreign product that contains sufficient US IP.

 

The EU, the UK, China, and India run their own dual-use control lists, so non-US shippers often need to check both. Get that classification wrong, and the problem is not a paperwork correction. It can mean an unlicensed export, a shipment held at the border, and penalties that often exceed the value of the hardware.

What is an ECCN?

An Export Control Classification Number (ECCN) is a five-character alphanumeric code on the US Commerce Control List (CCL) that identifies commodities, software, and technology subject to export controls. It is part of the Export Administration Regulations (EAR), administered by the Bureau of Industry and Security (BIS), and it determines whether an export, reexport, or in-country transfer needs a license.

 

ECCNs describe products technically, not commercially. Two products that look alike in a catalog can carry different ECCNs due to differences in processing performance, encryption functionality, frequency range, or other measurable parameters.

 

If an item is subject to the Export Administration Regulations (EAR) but not described in any ECCN, it is designated EAR99. EAR99 items usually ship without a license, but they can still need one for a restricted end user, end use, or destination.

How an ECCN is Structured

ECCN structure

The ten categories are:

  • 0 Nuclear and miscellaneous
  • 1 Materials and chemicals
  • 2 Materials processing
  • 3 Electronics
  • 4 Computers
  • 5 Telecommunications (Part 1) and information security (Part 2)
  • 6 Sensors and lasers
  • 7 Navigation and avionics
  • 8 Marine
  • 9 Aerospace and propulsion

 

The five product groups are:

  • A Systems, equipment, and components
  • B Test, inspection, and production equipment
  • C Materials
  • D Software
  • E Technology.

 

The last three digits also signal why the item is controlled. Entries in the 0xx to 3xx range are generally multilateral controls, while 9xx entries, such as 5A992, are mostly controlled for anti-terrorism reasons only.

Why Getting the ECCN Right Matters for Tech Exports

A wrong ECCN can make a licensed export look license-free, apply a license exception that does not fit, or file inaccurate export data. Each of those can be a separate violation. Penalties are assessed per violation, and each shipment can be a separate violation, so risk exposure scales with volume.

 

The consequences can vary from:

Civil penalties

Criminal penalties

Denial of export privileges

Operational impact

ECCNs That Apply To IT, AI, and Dual-Use Hardware

Most tech hardware is controlled for two reasons: the encryption it uses or the computing performance it delivers. Some common ECCNs include:

Hardware TypeECCNs to checkWhat drives the classification
AI accelerators, data center GPUs, and advanced logic chips3A090 (.a, .b, .c)Computing performance thresholds. Most GPUs fall under 3A090 or 3A991
Servers, systems, and assemblies containing 3A090 chips4A090Whether the system contains 3A090 integrated circuits
Network infrastructure: routers, switches, firewalls, VPN gateways5A002 / 5D002Network infrastructure items under 740.17(b)(2) are not eligible for mass market treatment
Items not described on the CCLEAR99Still licensable for embargoed destinations and restricted parties

The above information has been collated from: Greenberg Traurig, Wilson Sonsini, and BIS.

ECCNs and Advanced Computing

Advanced computing controls have changed repeatedly since 2022, and they are the area where outdated guidance causes the most risk. In May 2025, BIS announced it would not enforce the January 2025 AI Diffusion Rule and would issue a replacement. On May 31, 2026, BIS clarified that a license is still required for 3A090 and 4A090 items destined to entities headquartered in Country Group D:5 (which includes China) or Macau, or whose ultimate parent is located elsewhere (Holland & Knight).

 

In practice, this means the ownership of your customer matters as much as their address. A data center buyer in a third country whose parent is headquartered in China may trigger a licensing requirement.

 

The same ECCN can be license-free to one destination and license-required to another. That is why classification and destination planning must happen together before the hardware ships.

ECCN vs HS, HTS, Schedule B, EAR99, and ITAR

An ECCN is distinct from and unrelated to Schedule B and HTS codes. Most cross-border tech shipments need several of these codes at once, each for a different authority.

CodePurposeWho maintains itUsed on
ECCNExport control: Is a license required?BIS, US Department of CommerceExport licensing, EEI filings, commercial documents
EAR99Designation for items subject to the EAR but not on the CCLBISSame as ECCN
HS CodeInternational tariff classification (6 digits)World Customs OrganizationCustoms declarations worldwide; drives duties and many import permits
HTS CodeUS import tariff classification (10 digits)US International Trade CommissionUS import entries and duty calculation
Schedule BUS export statistics (10 digits)US Census BureauEEI filings in AES

A common error is using the HS code to decide export control status. HS codes tell you duties and import requirements; they never tell you whether a US export license is needed. Read more in our guide to the Export Administration Regulations.

How TecEx Assists with ECCN Classifications

ECCN classification is not just a paperwork requirement. It determines where you can ship, whether you need a license, and whether your company is exposed to civil or criminal liability. Whether you are a manufacturer, distributor, software developer, or integrator, understanding your ECCN is foundational to lawful international trade.

 

If your organization exports products, software, or technology from (or containing content from) the United States, ECCN classification is not optional. It is a core compliance obligation. Let TecEx guide you through these complexities and help your business scale across borders without challenges.
