ECCN Explained: Classifying Items Under the EAR
An ECCN — Export Control Classification Number — is the five-character code on the Commerce Control List (CCL) that identifies where a dual-use item sits under the Export Administration Regulations, and it’s the starting point for deciding whether your export needs a license. If your item is subject to the EAR but isn’t described by any ECCN, it’s designated EAR99 — the catch-all that covers most ordinary commercial goods. Reading and determining the ECCN correctly is the single most important classification step for any exporter of commercial or dual-use products. This guide explains how the code is structured, how to find yours, and what it means for licensing.
It builds on the three export-control regimes: the ECCN is how you classify items that fall under the EAR specifically.

How to Read an ECCN
An ECCN is five characters — a digit, a letter, then three digits, like 4A001. Each part has meaning:
| Position | Meaning | Example (4A001) |
|---|---|---|
| 1st (digit) | CCL category (0–9) | 4 = Computers |
| 2nd (letter) | Product group (A–E) | A = Equipment, assemblies, components |
| Last 3 (digits) | The specific entry and reason for control | 001 |
The 10 CCL categories are: 0 Nuclear; 1 Materials, Chemicals, Microorganisms & Toxins; 2 Materials Processing; 3 Electronics; 4 Computers; 5 Telecommunications & Information Security; 6 Lasers & Sensors; 7 Navigation & Avionics; 8 Marine; 9 Aerospace & Propulsion. The 5 product groups are: A Equipment/components; B Test/inspection/production equipment; C Materials; D Software; E Technology.
EAR99: The Catch-All
If your item is subject to the EAR but isn’t listed under any ECCN, it’s EAR99. Most everyday commercial products are EAR99, and they generally ship without a license — but EAR99 is not a free pass. A license can still be required if the item is going to an embargoed country, a restricted party (on the Entity List, Denied Persons List, or OFAC SDN List), or for a prohibited end use such as weapons proliferation. Treating “EAR99” as “no rules apply” is a classic and costly compliance mistake.
How to Determine Your ECCN
There are three ways, in increasing order of reliability:
- Ask your manufacturer/supplier. They often already know the item’s ECCN.
- Self-classify against the CCL by working through the categories and the technical parameters of each entry.
- Request an official classification (CCATS) from BIS through the SNAP-R system when you need certainty. This is the authoritative answer.
Self-classification is acceptable but the legal responsibility for getting it right stays with you, so document your reasoning — and when the stakes or ambiguity are high, get BIS’s determination.
From ECCN to License Decision
The ECCN is the input to the license question, not the answer by itself. Each ECCN entry lists its reasons for control (national security, missile technology, anti-terrorism, etc.). You take those reasons to the Commerce Country Chart, cross-reference the destination country, and that intersection tells you whether a license is required for that shipment — unless a license exception applies. The full mechanics are in our guide to exporting with an export license.
Frequently Asked Questions
What is an ECCN?
An Export Control Classification Number is a five-character code on the Commerce Control List that identifies a dual-use item under the EAR. It encodes the item’s category, product group, and reason for control, and it drives whether an export license is required.
What does EAR99 mean?
EAR99 is the designation for items subject to the EAR that are not listed under any specific ECCN. Most commercial goods are EAR99 and usually ship without a license, but a license may still be required for sanctioned destinations, restricted parties, or prohibited end uses.
How do I find my product’s ECCN?
Ask your manufacturer or supplier, self-classify against the Commerce Control List using your item’s technical specifications, or request an official classification (CCATS) from BIS for certainty. The exporter remains responsible for the accuracy of the classification.
Does an ECCN mean I need a license?
Not by itself. The ECCN’s reasons for control are checked against the Commerce Country Chart for the destination to determine whether a license is required, and a license exception may still apply. Restricted parties or prohibited end uses can require a license regardless.
Correct ECCN classification is the foundation of EAR compliance — and the basis of every license decision. Reidel Law Firm helps exporters classify items, request BIS determinations, and build compliance programs on flat-fee terms. Get an export compliance memo.
