2,4,6‑tris(2‑ethyl‑1‑aziridinyl)‑1,3,5‑triazine (HX‑874) (CAS 18924‑91‑9); and
(c) 1,1′‑trimethyladipoylbis(2‑ethylaziridine) (HX‑877) (CAS 71463‑62‑2).
 (g) Precursors, as follows:
 (1) BCMO (3‑3‑bis(chloromethyl)oxetane) (CAS 78–71–7);
 (2) DADN (1,5‑diacetyl‑3,7‑dinitro‑1, 3, 5, 7‑tetraazacyclooctane);
 (3) dinitroazetidine‑t‑butyl salt (CAS 125735–38–8);
 (4) CL‑20 precursors (any molecule containing hexaazaisowurtzitane) (for example, HBIW (hexabenzylhexaazaisowurtzitane), TAIW (tetraacetyldibenzylhexa‑azaisowurtzitane));
 (5) TAT (1, 3, 5, 7‑tetraacetyl‑1, 3, 5, 7‑tetraaza‑cyclooctane) (CAS 41378–98–7);
 (6) tetraazadecalin (CAS 5409–42–7);
 (7) 1,3,5‑trichorobenzene (CAS 108–70–3);
 (8) 1,2,4‑trihydroxybutane (1,2,4‑butanetriol) (CAS 3068–00–6).
 (h) Any explosive, propellant, pyrotechnic, fuel, oxidiser, binder, additive, or precursor that (MT for articles designated as such):
 (1) is classified; or
 (2) is being developed using classified information.
 (i) Developmental explosives, propellants, pyrotechnics, fuels, oxidisers, binders, additives, or precursors therefor funded by the United States Government via contract or other funding authorisation.
Note 1: This paragraph does not control explosives, propellants, pyrotechnics, fuels, oxidisers, binders, additives, or precursors therefor:
(a) in production; or
(b) identified in the relevant United States Government contract or other funding authorisation as being developed for both civil and military applications.
Note 2: Note 1 does not apply to defence articles enumerated on this list, whether in production or development.
Note 3: This paragraph applies only to those contracts and funding authorisations that are dated 5 January 2015, or later.
 (j) Technical data and defence services directly related to the defence articles described in paragraphs (a) to (i) (MT for articles designated as such).
 (k) The following interpretations explain and amplify the terms used in this category and elsewhere in this list:
 (1) Category V contains explosives, energetic materials, propellants and pyrotechnics and specially formulated fuels for aircraft, missile and naval applications. Explosives are solid, liquid or gaseous substances or mixtures of substances, which, in their primary, booster or main charges in warheads, demolition or other military applications, are required to detonate;
 (2) the resulting product of the combination or conversion of any substance controlled by this category into an item not controlled will no longer be controlled by this category provided the controlled item cannot easily be recovered through dissolution, melting, sieving, etc. As an example, beryllium converted to a near net shape using hot isostatic processes will result in an uncontrolled part. A cured thermoset containing beryllium powder is not controlled unless meeting an explosive or propellant control. The mixture of beryllium powder in a cured thermoset shape is not controlled by this category. The mixture of controlled beryllium powder mixed with a typical propellant binder will remain controlled by this category. The addition of dry silica powder to dry beryllium powder will remain controlled;
 (3) subparagraph (c)(4)(ii)(A) does not apply to boron and boron carbide enriched with boron‑10 (20% or more of total boron‑10 content;
 (4) theoretical specific impulse (Isp) is calculated using standard conditions
