• CW (Chemical Weapons Convention): CW applies to 1C351.d.15 and .d.16 and a license is required for CW reasons for all destinations, including Australia, Canada, and the United Kingdom, as follows: CW applies to 1C351.d.15 for ricin in the form of (1) Ricinus communis AgglutininII (RCA_(II)), also known as ricin D or Ricinus Communis LectinIII (RCL_(III)) and (2) Ricinus communis LectinIV (RCL_(IV)), also known as ricin E. CW applies to 1C351.d.16 for saxitoxin identified by C.A.S. #35523-89-8. See § 742.18 of the EAR for licensing information pertaining to chemicals subject to restriction pursuant to the Chemical Weapons Convention (CWC). The Commerce Country Chart is not designed to determine licensing requirements for items controlled for CW reasons. CW applies to 1C351.d.15 and .d.16 and a license is required for CW reasons for all destinations, including Australia, Canada, and the United Kingdom, as follows: CW applies to 1C351.d.15 for ricin in the form of (1) Ricinus communis AgglutininII (RCA_(II)), also known as ricin D or Ricinus Communis LectinIII (RCL_(III)) and (2) Ricinus communis LectinIV (RCL_(IV)), also known as ricin E.

See § 742.18 of the EAR for licensing information pertaining to chemicals subject to restriction pursuant to the Chemical Weapons Convention (CWC). The Commerce Country Chart is not designed to determine licensing requirements for items controlled for CW reasons.

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 1C351

The controls often apply to some paragraphs only, so check the full paragraph, for example 1C351.a.
