ECCN 9D004

Other "software" as follows

Software. Reasons for control: NS (National security), AT (Anti-terrorism).

Does 9D004 need a license to your country?

Enter the full classification (for example 9D004.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 requirement check

Item classification and destination. No account needed.

An ECCN (such as 5A992.c) is an exact match and works best. Word search matches the official CCL wording and a reviewed list of everyday names as you write them; it does not guess what you mean or fix spelling. Don’t know the ECCN? Use Find the ECCN.

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.

  • NS (National security): NS applies to entire entry, except 9D004.e for 9A012.a.1 items.
    Country Chart column NS1: a license is needed to 193 countries with an X

  • 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.

  • TSR: N/A.
  • Special Conditions for STA
  • STA: License Exception STA may not be used to ship or transmit software in 9D004.a and 9D004.c to any of the destinations listed in Country Group A:6 (See supplement no.1 to part 740 of the EAR)

Items in 9D004

The controls often apply to some paragraphs only, so check the full paragraph, for example 9D004.a.
