ECCN 2B201
NPATMachine tools, and any combination thereof, other than those controlled by 2B001, for removing or cutting metals, ceramics or composites, which, according to manufacturer's technical specifications, can be equipped with electronic devices for simultaneous contouring control in two or more axes.
What This ECCN Covers
ECCN 2B201 controls certain machine tools for removing or cutting metals, ceramics, or composites that are not already captured by 2B001 but, per the manufacturer's specifications, can be equipped for simultaneous "contouring control" in two or more axes — including specified grinding and milling machines that meet positioning-accuracy thresholds. The entry is controlled for Nuclear Nonproliferation and Anti-Terrorism because precision multi-axis machining is a key capability for producing centrifuge and weapons components.
Who needs to check this?
Machine-tool builders and exporters of CNC grinding and milling equipment, and resellers shipping used industrial machinery abroad.
Compliance tip
2B201 is an NP/AT entry, so nuclear end-use and end-user red flags under EAR Part 744 apply even when a license exception otherwise seems available. Verify positioning accuracy against the entry thresholds — machines whose accuracy is worse (a larger value) than the stated limit may fall outside control — and confirm license-exception eligibility in the entry.
Items Covered
- a.Gears;
- b.Crank shafts or cam shafts;
- c.Tools or cutters;
- d.Extruder worms;
- a.Machine tools for turning, that have positioning accuracies according to ISO 230/2 (2006) with all compensations available better (less) than 4.5 µm along any linear axis (overall positioning) for machines capable of machining diameters greater than 35 mm;
- b.Machine tools for milling, having any of the following characteristics:
- 1. Positioning accuracies according to ISO 230/2 (2006) with "all compensations available" equal to or less (better) than 4.5 µm along any linear axis (overall positioning);
- 2. Two or more contouring rotary axes; or
- 3. Five or more axes which can be coordinated simultaneously for "contouring control."
- a.X-axis travel greater than 2 m; and
- b.Overall positioning accuracy according to ISO 230/2 (2006) on the x-axis more (worse) than 22.5 µm.
- c.Machine tools for grinding, having any of the following characteristics:
- 1. Positioning accuracies according to ISO 230/2 (2006) with "all compensations available" equal to or less (better) than 3 µm along any linear axis (overall positioning);
- 2. Two or more contouring rotary axes; or
- 3. Five or more axes which can be coordinated simultaneously for "contouring control."
- a.Cylindrical external, internal, and external-internal grinding machines having all of the following characteristics:
- b.Jig grinders that do not have a z-axis or a w-axis with an overall positioning accuracy less (better) than 3 microns. Positioning accuracy is according to ISO 230/2 (2006).
Control Reasons
Items controlled for nuclear nonproliferation reasons.
Items controlled for anti-terrorism reasons. Most items on the CCL have AT controls.
