ECCN (Export Control Classification Number)
An ECCN (Export Control Classification Number) is a five-character alphanumeric code the U.S. Commerce Department's Bureau of Industry and Security (BIS) uses to classify items on the Commerce Control List for export licensing purposes. It answers a different question than an HTS code: an HTS code sets the duty owed on import, while an ECCN determines whether an export license is required based on the item, the destination, the end use, and the end user. An item not described by any entry on the Commerce Control List is classified EAR99, the default catch-all that generally, but not always, ships without a license.
What an ECCN actually classifies
The Export Administration Regulations (EAR) govern the export of most U.S.-origin commercial and dual-use items — goods with both civilian and military or security applications, from industrial electronics to certain chemicals and software. BIS's Commerce Control List (CCL) is the reference table; an ECCN is the code that says where on that list a given item falls.
The code has a fixed structure: a category digit (0–9, broad technology area such as electronics or materials processing), a product group letter (A–E, covering equipment, test gear, materials, software, or technology), and three more digits identifying the specific reason for control and the entry within that group. Two items with the same category and group can still require very different licensing depending on the last three digits.
ECCN vs. HTS code: two agencies, two questions
These get confused because both are alphanumeric codes attached to the same SKU on the same compliance paperwork, but they answer unrelated questions.
| HTS code | ECCN | |
|---|---|---|
| Question answered | What duty is owed on import? | Is an export license required? |
| Governing regulation | Harmonized Tariff Schedule | Export Administration Regulations (EAR) |
| Administered by | U.S. International Trade Commission / CBP | Bureau of Industry and Security (BIS), Commerce Department |
| Applies to | Imports into the U.S. | Exports (and some re-exports and transfers) from the U.S. |
A product can have a straightforward HTS code and still require an export license under its ECCN, and the reverse: a controlled-sounding technical product can turn out to be EAR99 with no license required to most destinations.
Whether a license is actually required
The ECCN alone doesn't answer that — it has to be cross-referenced against the Commerce Country Chart along with the destination country, the end use, and the end user (including denied-party and restricted-entity screening). The same ECCN can mean no license required to one country and a required license to another.
Companies can self-classify against the CCL, which is legally acceptable and is how most classification gets done. For a documented, BIS-issued determination, a company can request a formal classification (a CCATS) through BIS's SNAP-R system, which creates a paper trail that self-classification alone doesn't produce.
Where it belongs in product data
For a manufacturer or distributor of electronics, industrial equipment, or specialty chemicals, ECCN is increasingly requested as a catalog attribute alongside the HTS code — international B2B buyers and procurement platforms want both on file before they'll transact. Missing or wrong ECCN data isn't just a data-quality gap; shipping a controlled item without a required license is a real compliance exposure, so this is one of the few attribute fields worth routing through a trade compliance review rather than filling automatically.
Frequently asked questions
What does EAR99 mean?
EAR99 is the classification for an item that's subject to the Export Administration Regulations but isn't specifically described by any entry on the Commerce Control List. It's not something an exporter picks directly — it's what remains after checking an item against every relevant CCL entry and finding no match. Most EAR99 items can ship to most destinations and end users without an individual license (a status BIS calls No License Required), though destination, end use, and end user can still trigger a requirement.
Is an ECCN the same as an HTS code?
No. An HTS code determines the duty owed when an item enters the United States. An ECCN determines whether a license is required to export an item out of the United States. They're issued under different regulations by different parts of the federal government, and a product needs to be evaluated separately under each.
Does every product need an ECCN?
Every item subject to the EAR falls somewhere in the classification scheme, but for most commercial products that resolves to EAR99 rather than a specific Commerce Control List entry. Products with more sensitive technical characteristics — encryption, certain sensors, specialized materials, dual-use industrial equipment — are more likely to land on an actual CCL entry and need closer review.
Can a company classify its own products, or does BIS have to do it?
Self-classification against the Commerce Control List is legally acceptable and is how most companies handle it. A company can alternatively request a formal classification from BIS (a Commodity Classification Automated Tracking System determination, or CCATS) through the SNAP-R system, which is slower but produces a documented, BIS-issued determination rather than an internal judgment call.
