Report by the Chair of the Technical Experts Meeting: Update of MTCR Annex

The MTCR Technical Experts Meeting recently conducted a regular revision of the MTCR Equipment, Software, and Technology Annex. This revision has ultimately led to several changes in control text, including the introduction of controls on the propellant substance hydroxylammonium nitrate (HAN) in a new Item 4.C.3.b. and a clarification of the term ‘combined cycle’ engines in the Technical Note to Item 3.A.2. The most recent version of the MTCR Annex is now available on the MTCR website. The MTCR Annex cover page identifies allamended sections and these are further illustrated in the MTCR Annex track changes document.
