Category 1 - Special Materials and Related Equipment

Category 1 under the Export Administration Regulations covers special materials and related equipment, such as certain chemicals, biological agents, and specialized manufacturing tools, that are controlled due to their potential dual-use applications. Export of these items requires a license from the U.S. Department of Commerce unless an exception applies, and they are listed in the Commerce Control List with specific ECCNs. This category aims to prevent the proliferation of technologies that could threaten national security.
