Items Covered
- a.Computer controlled or "numerically controlled" Coordinate Measuring Machines (CMM), having a three dimensional length (volumetric) maximum permissible error of length measurement (E0,MPE) at any point within the operating range of the machine (i.e., within the length of axes) equal to or less (better) than (1.7 + L/1,000) µm (L is the measured length in mm) according to ISO 10360-2 (2009);
- b.Linear displacement measuring instruments or systems, linear position feedback units, and "electronic assemblies", as follows:
- 1. 'Non-contact type measuring systems' with a 'resolution' equal to or less (better) than 0.2 µm within 0 to 0.2 mm of the 'measuring range';
- 2. Linear position feedback units "specially designed" for machine tools and having an overall "accuracy" less (better) than (800 + (600 × L/1,000)) nm (L equals effective length in mm);
- 3. Measuring systems having all of the following:
- 3.a. Containing a "laser";
- 3.b. A 'resolution' over their full scale of 0.200 nm or less (better); and
- 3.c. Capable of achieving a "measurement uncertainty" equal to or less (better) than (1.6 + L/2,000) nm (L is the measured length in mm) at any point within a measuring range, when compensated for the refractive index of air and measured over a period of 30 seconds at a temperature of 20±0.01 °C;
- 4. "Electronic assemblies" "specially designed" to provide feedback capability in systems controlled by 2B006.b.3;
- c.Rotary position feedback units "specially designed" for machine tools or angular displacement measuring instruments, having an angular position "accuracy" equal to or less (better) than 0.9 second of arc;
- d.Equipment for measuring surface roughness (including surface defects), by measuring optical scatter with a sensitivity of 0.5 nm or less (better).
Control Reasons Explained
This ECCN is controlled for the following reasons. Each reason maps to a column on the Commerce Country Chart, which determines whether a license is required for a given destination.
- NSNational Security
- Items that could contribute to the military potential of countries of concern. Check the Commerce Country Chart column for NS to determine license requirements.
- NPNuclear Nonproliferation
- Items relevant to nuclear weapons development or delivery systems. Additional scrutiny applies under 10 CFR Part 810 and NRC regulations.
- ATAnti-Terrorism
- Basic anti-terrorism controls that apply to most items on the CCL. A license is required for exports to countries designated as state sponsors of terrorism.
Common Questions About 2B006
What does ECCN 2B006 cover?
ECCN 2B006 is an entry on the Commerce Control List (Materials Processing). The List of Items Controlled below describes the products, software, or technology captured by this classification. Compare your item against those parameters when self-classifying.
How do license requirements work for this ECCN?
License need depends on the control reasons shown for this code (for example NS, RS, MT, AT), the destination country, and how your transaction maps against the Commerce Country Chart, de minimis, and other EAR provisions. This page is a research aid only. Confirm against the current rule text and your specific facts before exporting.
Where is the official text for this ECCN?
The legal text appears in Supplement No. 1 to part 774 of the Export Administration Regulations (15 CFR Part 774). Use the official BIS link on this page to open the current supplement entry for this ECCN.
What if my product matches more than one ECCN?
When several ECCNs appear to fit, the controlling entry is usually the one that is most specific to your item's form, function, or technical limits. Cross-references in the List of Items Controlled and related ECCNs listed on this page are common starting points for narrowing the choice.
How often should I re-check this classification?
The Commerce Control List changes when BIS publishes new or amended rules. Revisit the official entry when regulations update, when the product's technical parameters change, or when the destination, end-user, or end-use of a transaction changes.
What do the control reason codes mean?
Each control reason (NS, RS, MT, AT, etc.) maps to a column on the Commerce Country Chart in Supplement No. 1 to part 738 of the EAR. When a control reason applies to your ECCN and the destination country has an X in that column, a license is generally required unless an exception applies. See the Control Reasons Explained section on this page for details on each code.
