Entries differ in detail. The actual license requirement comes from the Commerce Country Chart and the ECCN entry, not from this table. ## Content **Intro:** An ECCN is the Export Control Classification Number that places an item on the Commerce Control List. This decoder explains each part of the number and the reason for control codes you will see on the ECCN entry and the Commerce Country Chart. **Sections:** #### How to read an ECCN **Body:** Take the example 3A001. The first digit is the CCL category, here Electronics. The letter is the product group, here A for equipment, assemblies and components. The last three digits identify the specific entry. Look up the entry in Supplement No. 1 to Part 774 of the EAR and read the License Requirements section, which lists the reasons for control. Then use the Country Chart in Supplement No. 1 to Part 738 to see whether a license is needed for the destination. #### Reasons for control drive the answer **Body:** A reason for control such as NS or RS only creates a license requirement for destinations marked on the Country Chart for that reason. AT applies to a small group of destinations. An ECCN with only AT control will often ship without a license to most countries, though sanctions and end-use rules still apply. That is why classification alone is not the license decision. You also need destination, end user and end use. **Bullets:** - Find the ECCN entry and its reasons for control - Check the destination on the Country Chart - Screen the party and the end use - Look for a license exception only after confirming a license is needed #### 600 series, 9x515 and EAR99 **Body:** Export reform moved many military items from the USML to the CCL as 600 series and 9x515 entries. These carry stricter policies than usual dual-use items, including control for most destinations and limits on license exceptions. EAR99 is the catch-all for items subject to the EAR but not listed. It is not a free pass, since embargoes, denied party lists and end-use restrictions apply to EAR99 shipments. #### Common mistakes **Body:** Teams copy the ECCN from a supplier or datasheet without checking it, use the wrong item such as the machine instead of its software, or classify a finished system by its commercial purpose when a component drives the control. Do not mix up ECCN with the Schedule B or HTS number, which are tariff codes. Keep the classification rationale on file and review it when the product changes. **Cta:** If your item master lacks ECCN data or you want automatic holds when a controlled item is ordered for a foreign ship-to, we can build that on your own ERP data. The decoder works without it. **Faq:** #### What is the difference between an ECCN and an HTS code? **Answer:** An ECCN is the export control classification from the Commerce Control List and determines licensing. An HTS or Schedule B number is a tariff code used for customs duties and trade statistics. Both may be needed on an export, but they answer different questions. #### What does EAR99 mean? **Answer:** EAR99 covers items that are subject to the EAR but not specifically listed on the Commerce Control List. They generally do not need a license for most destinations, but embargoed countries, restricted parties and prohibited end uses still require authorization. #### What is a 600 series ECCN? **Answer:** A 600 series ECCN, such as 9A610 or 3A611, covers military items moved from the USML to the CCL during export control reform. They are treated more strictly than ordinary dual-use items and have limited license exception availability. #### Can I rely on the manufacturer's ECCN? **Answer:** It is a useful input, but you are responsible for your own export decisions. A manufacturer ECCN may refer to a different configuration or version. Confirm that it matches your product and keep a copy of the statement with your records. ## Search terms eccn structure explained, commerce control list categories, eccn reasons for control ns rs at, how to read an eccn 3a001, ear99 vs eccn, 600 series eccn meaning, ccl product groups a b c d e, eccn lookup table --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
