Notes
Radiation-hardened and certain RF components used in defence and space systems commonly fall under ITAR rather than the EAR.
Overview
ITAR, the International Traffic in Arms Regulations, are the US rules, administered by the State Department's Directorate of Defense Trade Controls (DDTC), that control the export and temporary import of defence articles and defence services and the related technical data listed on the United States Munitions List (USML). For chip companies, ITAR applies mainly to custom devices, designs and data developed for military systems, while most commercial chips fall under the Commerce Department's EAR instead. ITAR is generally stricter than the EAR: it has few exemptions and requires registration even before any export.
How it works
The regulations sit in Title 22 of the US Code of Federal Regulations and implement the Arms Export Control Act of 1976. Part 121 is the Munitions List, organised in categories such as military electronics, spacecraft and missiles. Any person in the United States who manufactures or exports defence articles, or furnishes defence services, must register with DDTC, and a single occasion is enough to trigger that duty. Exports, re-exports and transfers then need a licence or an approved agreement.
The definition of an export is broad. Showing ITAR technical data, such as schematics, layout or test procedures, to a foreign person inside the United States counts as an export, so chip teams working on defence programmes control access to files, labs and meetings by nationality as well as by job. For electronics, Category XI of the USML covers military electronics and, among its parts and components, application specific integrated circuits and programmable logic devices programmed for defence articles; ASICs and PLDs programmed for items in the EAR's 600 series move instead to the Commerce control list.
Because ITAR follows the item into any product that incorporates it, some foreign buyers prefer parts marketed as 'ITAR-free'. Compliance therefore often shapes sourcing and product decisions, not only shipping.
Examples
- An ASIC programmed for a missile guidance system, controlled as a component under USML Category XI.
- A US design centre restricting access to a defence programme's layout database to US persons, with licences for any foreign staff.
- A space electronics supplier marketing a product line as ITAR-free to sell to European satellite makers.
- A first-time manufacturer of a defence article registering with DDTC before starting work.
Why it matters
Export compliance managers, defence microelectronics programme managers, engineers on rad-hard and military products and the IT teams that run their design environments must all work within ITAR. Violations can bring heavy fines, debarment and criminal charges, and a single uncontrolled file share with a foreign colleague can be a breach, so ITAR shapes staffing, data systems and supplier choice on defence chip work.
