ECCN 4A994
Computers, "electronic assemblies" and related equipment, not controlled by 4A001 or 4A003, and "specially designed" "parts" and "components" therefor
Systems, equipment and components. Reasons for control: AT (Anti-terrorism).
Does 4A994 need a license to your country?
Enter the full classification (for example 4A994.a) and a destination. The check reads the Country Chart, the end-use and embargo rules, and shows the rule and source behind the answer.
License requirements
Each control below comes from the entry’s License Requirements table. Where it names a Country Chart column, the countries with an X in that column need a license for the items the control covers, unless a License Exception applies.
- AT (Anti-terrorism): AT applies to entire entry. No Country Chart country has an X in column AT1; the destinations this control targets are under “Not decided by the Country Chart” below.
Not decided by the Country Chart: Covered Donetsk region of Ukraine (DNR), Covered Luhansk region of Ukraine (LNR), Crimea region of Ukraine, Cuba, Iran, Korea, North, Syria. These destinations are under embargoes or other special controls in 15 CFR Part 746, which require a license for most items whatever the chart shows. Russia and Belarus also have broad Part 746 controls in addition to the chart.
A blank on the Country Chart is not permission to ship. End-use and end-user rules (15 CFR Part 744), embargoes and sanctions (Part 746), and the parties to the transaction still apply. Use the check above for your item and country.
List-based License Exceptions
As the entry lists them. Each exception has its own conditions in 15 CFR Part 740, and § 740.2 bars or limits most of them for Russia, Belarus, Country Group D:5 and embargoed destinations, so an entry’s “Yes” does not mean it is available everywhere.
- LVS: N/A
- GBS: N/A
