Classification of an actual article is the exporter's responsibility and can require a commodity jurisdiction request or a written determination. It is not legal advice. Entries inside each category change by rule, so read the current text of 22 CFR 121.1. ## Content **Intro:** Anyone in defense electronics hears USML category numbers daily: Category XI, Category XII, Category VIII. This reference lists all 21 categories by title and the main regulation names, so purchasing, contracts and shop floor staff can speak the same language as the export compliance office. **Sections:** #### How to use the reference **Body:** Search for a word such as electronics, aircraft or spacecraft to see the categories that mention it. Use the Type column to isolate categories, regulations and agencies. Export the table to attach to a supplier onboarding pack or a training slide. The category is only the start of classification. Each category has paragraphs (a), (b), (c) and so on, and the specific paragraph, plus any notes and technical parameters, decide whether your item is covered. #### ITAR versus EAR **Body:** ITAR controls items on the USML, which are specially designed for military use, and is run by the State Department. EAR controls dual-use items and items moved off the USML, and is run by Commerce. Moved items sit in the 600 series of ECCNs. Defense electronics suppliers often handle both: a ruggedized board may be ITAR while a commercial FPGA on it is EAR. Marking, storage, foreign person access and technical data handling differ, so classify at the part and the assembly level. **Bullets:** - Keep a classification record for each part and assembly - Treat technical data and software as controlled, not only hardware - Check foreign person access to shared drives and ERP screens - Review classification when a design changes #### Common mistakes **Body:** A common error is classifying by the customer's name rather than by the article. Another is assuming that a purchased commercial part stays commercial after it is built into a USML assembly. The assembly takes its own classification, and supplier flowdown clauses may require the same handling for the parts. Also avoid emailing technical data through uncontrolled tools. Keep the classification, the license or exemption reference and the end-use details on the order record so audits are quick. **Cta:** Netray designs private, on-prem AI so controlled data stays inside your environment. We can discuss how classification fields could surface in your ERP. **Faq:** #### How many USML categories are there? **Answer:** There are 21 categories, numbered I to XXI. Each category lists the covered articles, technical data and defense services in paragraphs. The official list is in 22 CFR 121.1 and is amended by rule from time to time. #### Which USML category covers military electronics? **Answer:** Category XI is titled Military Electronics, including items such as certain radar and electronic warfare equipment. Imaging and fire control items are in XII, and avionics specially designed for aircraft may be in VIII. The exact paragraph decides. #### Does this tool classify my product? **Answer:** No. It lists the categories for orientation. Classification needs analysis of the specific design against the current regulation, and sometimes a government determination. Work with your export compliance lead or counsel for decisions. #### What is a 600 series ECCN? **Answer:** These are Commerce Control List entries for military items that were moved from the USML to EAR control. They are numbered with a 6 in the position that identifies the group, for example 3A611 for certain military electronics. ## Search terms usml categories list, usml category xi military electronics, itar usml category list, usml category xii fire control, itar vs ear difference, usml 21 categories, export control reference table --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
