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 6A005

What does ECCN 6A005 cover?
ECCN 6A005 is an entry on the Commerce Control List (Sensors & Lasers). 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.
