ECCN Lookup: How to Look Up an ECCN on the Commerce Control List

"ECCN lookup" means two different things, and mixing them up is the most common way to end up with the wrong export classification. Sometimes you have a code — say 5A992 — and want to know what it covers. Sometimes you have a product and want to know its code. The first is a lookup; the second is a classification. This guide covers both, and where each one stops.

Where the ECCNs live

Every ECCN is listed on the Commerce Control List (CCL), Supplement No. 1 to Part 774 of the Export Administration Regulations (EAR). The CCL is published free on the Electronic Code of Federal Regulations (eCFR) and on the Bureau of Industry and Security (BIS) website, one PDF per category. It is the only authoritative source: any lookup tool, including ours, is a way of reading it.

Looking up a known ECCN

If you already have a code — from a supplier, a previous shipment or a manufacturer's website — look it up like this:

1. Read the code. The first digit is the category (0–9), the letter is the product group (A–E), and the three digits identify the entry. ECCN number structure explained decodes every part, including sub-paragraphs such as .c or .b.5.
2. Open the entry in that category's part of the CCL.
3. Read the License Requirements — the reasons for control (NS, MT, AT, RS and so on) and the Country Chart columns they point to.
4. Read the Items paragraph — the technical parameters. The code is only right for your item if the item meets that paragraph.
5. Check the notes — exclusions and related controls often change the answer.

How to read an ECCN entry explains each block of an entry in detail.

Looking up an ECCN from a product

If you start from a product, there is no search box in the regulation that returns its code. The CCL is written in technical parameters — processing performance, frequency, accuracy, operating temperature — not in product names or part numbers. That is deliberate: two products with the same name can sit in different entries because of one parameter.

Three tools narrow the search:

• The CCL alphabetical index. BIS publishes an index of commodities with the entries they may fall under. It is a list of candidates, not an answer.
• A keyword search of the CCL text for the item's function or key parameter.
• The manufacturer's published ECCN. Many large manufacturers publish their classifications — see where manufacturers publish their ECCNs.

Each of these gives you candidate entries. Turning a candidate into a classification means reading the entry and matching the paragraph — the steps in how to find the ECCN for your product.

Why a lookup is not a classification

Consider three examples:

• An uncooled thermal camera may look up as "6A003 — cameras". Whether it is 6A003.b.4.b, falls under a note that excludes it, or drops to 6A993 depends on its focal plane array and frame rate.
• A Wi-Fi router with WPA3 uses encryption, which points to Category 5 Part 2 — but it is usually 5A992.c (mass market), not 5A002, because of the Cryptography Note.
• An accelerometer may be 7A001.a.1, 7A001.a.2 or not controlled at all, depending on its acceleration range and bias stability.

In each case the lookup finds the right neighbourhood; the paragraph decides the address. Using the heading alone is one of the most common classification mistakes.

What to record

Whether you look up or classify, keep a record: the entry and paragraph, the parameters you compared, the source (manufacturer, your own analysis or a BIS ruling), the date and the version of the regulation. Export records under Part 762 of the EAR are generally kept for five years.

Using the CCL alphabetical index well

• Search by function, not brand. "Oscilloscope", "focal plane array", "bearing", "encryption" — the index lists commodities, not products.
• Collect every candidate. The index often points to several entries for one term; review all of them.
• Follow the related controls. Entries you find this way point to others (the USML, 600 series) you must check first.
• Do not stop at the index. The index does not classify — the entry's paragraph does.

ECCN lookup checklist

1. Do you have a code, or only a product?
2. If a code: open the entry, read the reasons for control and the paragraph, and check the notes.
3. If a product: collect candidates from the index, keyword search and the manufacturer.
4. Confirm jurisdiction before relying on any ECCN.
5. Match the paragraph with the item's parameters, in the entry's units.
6. Record the entry, paragraph, source and date.

Common lookup questions

Is an HTS code the same as an ECCN? No. The Harmonized Tariff Schedule code is for customs duty and statistics; the ECCN is for export controls. They are decided separately and neither implies the other. Is there one ECCN per product? An item has one classification, but a product with separable software, technology or components may involve several, depending on what is exported. See CCL product groups A–E.

ECCN lookup and classification in ECCN.help

ECCN.help offers both. Quick Search looks up entries by code or keyword from the CCL index, free and without limit. The ECCN.help Classification Workflow then classifies: it settles ITAR vs. EAR, offers candidate entries from your description, asks only the parameters the entry turns on — reading figures such as "-60 °C" or "30 WT" straight from your description — and shows the rule that decided the result. It is rule-based, with no AI: the same item gets the same answer against the same version of the regulation.

ECCN.help provides research and assistance, not legal advice. Verify every result against the regulation.
