PMPA’s Carli Kistler-Miller and David Wynn are joined by Tracy Nichols for a conversation about the International Traffic in Arms Regulations (ITAR) and what they mean for precision machining businesses. They deep dive on how export controls can apply not only to parts, but also to drawings, technical data, documentation, and interactions with foreign affiliates or personnel. This episode shows why ITAR compliance is often more complex than many shops expect and where common misunderstandings can create risk.
