ECCN 3B992
Equipment not controlled by 3B002, 3B993, or 3B994, for the inspection or testing of electronic "components" and materials, and "specially designed" "parts," "components" and "accessories" therefor.
Test, inspection and production equipment. Reasons for control: AT (Anti-terrorism).
Does 3B992 need a license to your country?
Enter the full classification (for example 3B992.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
Items in 3B992
The controls often apply to some paragraphs only, so check the full paragraph, for example 3B992.a.
