ECCN 2B001
NSNPATMachine tools and any combination thereof, for removing (or cutting) metals, ceramics or composites, which, according to the manufacturer's technical specifications, can be equipped with electronic devices for numerical control; as follows .
What This ECCN Covers
ECCN 2B001 covers numerically controlled (CNC) machine tools for removing or cutting metals, ceramics, or composites. This includes turning machines, milling machines, grinding machines, and combinations thereof that can be equipped with electronic controls for numerical control. These are controlled because precision machining is essential for manufacturing weapons components — particularly nuclear weapon implosion lenses, missile guidance housings, centrifuge rotors for uranium enrichment, and precision military components.
Who needs to check this?
Machine tool manufacturers, CNC equipment distributors, and companies exporting precision metalworking equipment — especially 5-axis machines or those with positioning accuracy better than the thresholds specified in the entry.
Compliance tip
NP (Nuclear Nonproliferation) controls apply to most sub-entries but with specific exceptions: turning machines limited to ≤35mm diameter, Swissturn bar machines limited to ≤42mm bar diameter, and milling machines with x-axis travel >2m and positioning accuracy worse than 22.5µm are excluded from NP. Check whether your machine meets any exclusion before assuming NP controls apply.
