ITAR Registered Defense Manufacturers in Greenville, SC

No, and conflating them is a common mistake. ITAR registration is a regulatory status with the State Department's Directorate of Defense Trade Controls that authorizes a company to manufacture or export defense articles and technical data on the United States Munitions List. It is not a facility security clearance, which is a separate Defense Department program for classified work, and it is not a quality certification like ISO 9001 or AS9100. A shop can be ITAR registered without holding any quality certification, and a high-quality AS9100 shop may not be ITAR registered if it does not handle controlled items. For a buyer sourcing defense work in Greenville, you typically need the supplier to carry several of these in combination: ITAR registration for the legal authority to handle controlled data, AS9100 for the aerospace quality system, and often NADCAP for special processes. Confirm each one separately rather than assuming that registration implies quality or that quality implies the legal authority to hold your controlled drawings.

Unlike ISO certificates, DDTC registration is not in a public database you can freely browse, so verification runs through the supplier and your own export-control function. Ask the supplier for confirmation of current registration and their DDTC registration code, then have your legal or compliance team validate it through appropriate channels. A genuinely registered supplier expects this request and will have a documented technology control plan showing how it restricts controlled technical data to U.S. persons and prevents unauthorized exports, including deemed exports to foreign nationals working on site. Probe their practices: how drawing access is controlled, how their IT systems keep technical data inside compliant boundaries, and how email and cloud storage are handled. A supplier that cannot articulate these controls is a compliance risk even with registration paperwork in hand. In Greenville's defense supply base, the credible ITAR shops also carry AS9100 and treat data handling as seriously as part quality, so weak answers on data control are a meaningful red flag.

Increasingly, yes, depending on the data and the contract. ITAR governs the export and handling of defense technical data, but when that data qualifies as controlled unclassified information under a Defense Department contract, the CMMC framework and the underlying NIST SP 800-171 security controls apply to how it is stored and transmitted. Many prime contractors and government buyers now expect their ITAR-registered suppliers to demonstrate this cybersecurity posture, particularly when drawings move electronically. When sourcing controlled work in Greenville, ask whether the supplier's data handling aligns with NIST 800-171 and where they stand on CMMC assessment, especially if you will transmit technical data by email or shared systems. The two requirements overlap but are distinct: ITAR is about who may lawfully access defense data, while CMMC and NIST 800-171 are about how that data is protected from a cybersecurity standpoint. A mature defense supplier treats both as part of the same obligation and can speak to its technology control plan and its IT security controls in the same conversation.

ITAR imposes recordkeeping obligations beyond the manufacturing paperwork. A registered supplier must retain records of controlled transactions and exports and be able to demonstrate compliance during a DDTC review or audit. For your specific job, that means the supplier should document the chain of custody for your technical data and hardware: who accessed the drawings, how access was restricted to authorized U.S. persons, and how the controlled items were stored and shipped. On the quality side, you should still receive the normal package appropriate to defense hardware, often AS9100-aligned, including first-article inspection, full material traceability, and certificates of conformance, plus NADCAP certificates for any special processes. The point for a buyer is that ITAR work carries a dual trail: the quality records proving the part is correct and the export-control records proving the data and hardware were handled lawfully. A Greenville supplier ready for controlled work will be comfortable producing both and will not treat the export-control documentation as an afterthought.
