ITAR is the International Traffic in Arms Regulations, the US regime controlling defense-related articles and technical data. ITAR registration restricts publication of controlled technical data, including on a manufacturer's own website.
ITAR governs articles and services on the United States Munitions List. A manufacturer working on covered items registers with the Directorate of Defense Trade Controls, and registration carries obligations about who may access technical data and where it may go. **Controlled technical data includes drawings, specifications, process detail, and software** related to a covered article. Publication is an export in the regulatory sense, so putting a controlled drawing on a public page can constitute an export to every country able to read it. **A deemed export** is the same principle applied to people rather than places: giving a foreign national access to controlled data inside the United States is treated as an export to that person's country. It reaches hiring, contractor access, and cloud storage, not only shipping. This is the one place where search work and compliance pull in opposite directions. The specification detail that makes a supplier findable is exactly the detail a controlled programme forbids publishing. The resolution is not to publish less generally, but to separate what is controlled from what is not: process capability, equipment, certifications, and general tolerance ranges are ordinarily publishable, while programme-specific data is not. **Access controls are the mechanism, and robots.txt is not one.** A disallow directive is a request that compliant crawlers honour voluntarily. Data that must not be published must not be on a public URL, and treating a robots file as protection converts a compliance obligation into an assumption about crawler behaviour. ITAR registration is also a supplier attribute in its own right. Stating registration alongside AS9100D certification tells a defense buyer the shop can hold the work at all, which is a filter applied before capability is considered. See [aerospace and defense manufacturing](/industries/aerospace) for how the restriction shapes those pages, and [AI crawler access](/ai-search/ai-crawler-access) for why the robots file is the wrong control. --- Source: https://manufacturingseo.ai/glossary/itar/ Last reviewed: 2026-08-08 Author: ManufacturingSEO.ai
