ECCN 1C007
NSMTATCeramic powders, ceramic matrix composite materials and 'precursor materials,' as follows .
What This ECCN Covers
ECCN 1C007 controls ceramic powders, ceramic "matrix" "composite" materials, and certain precursor materials defined in the entry. These high-temperature ceramics are used in thermal-protection and high-performance structural applications, including aerospace and missile components, which is why the entry carries National Security, Missile Technology, and Anti-Terrorism reasons.
Who needs to check this?
Producers and exporters of advanced ceramic powders, ceramic-matrix composites (CMCs), and their precursor materials for aerospace and high-temperature use.
Compliance tip
Classification depends on the specific composition and form in the entry — verify your material against those criteria. Because Missile Technology applies to parts of this entry, license exceptions are generally limited; classify carefully and apply EAR Part 744 end-use diligence.
