b. Heat shields and components therefor, fabricated of ceramic or ablative materials;

c. Heat sinks and components therefor, fabricated of light‑weight, high heat capacity materials;

d. Electronic equipment specially designed for re-entry vehicles.
9. A. 117. Staging mechanisms, separation mechanisms, and interstages, usable in "missiles".
N.B.: SEE ALSO 9A121.
9. A. 118. Devices to regulate combustion, usable in engines, which are usable in "missiles" or "unmanned aerial vehicles" specified by 9A012, 9A011 or 9A111.
9. A. 119. Individual rocket stages, usable in complete rocket systems or "unmanned aerial vehicles", capable of a range of 300 km, other than those specified by 9A005, 9A007, 9A009, 9A105, 9A107 and 9A109.
Note: Certain items specified in 9A119 may be subject to the MTCR Guidelines for Sensitive Missile‑Relevant Transfers.
9. A. 120. Liquid or gel propellant tanks, other than those specified by 9A006, specially designed for propellants specified by 1C111 or 'other liquid or gel propellants', used in rocket systems capable of delivering at least a 500 kg payload to a range of at least 300 km.
Note: In 9A120 'other liquid or gel propellants' includes, but is not limited to, propellants specified in the Munitions List.
9. A. 121. Umbilical and interstage electrical connectors specially designed for "missiles".
Technical Note:
Interstage connectors in 9A121 also include electrical connectors installed between a "missile" and its payload.
9. A. 350. Spraying or fogging systems, specially designed or modified for fitting to aircraft, "lighter‑than‑air vehicles" or "unmanned aerial vehicles", and specially designed components therefor, as follows:
a. Complete spraying or fogging systems capable of delivering, from a liquid suspension, an initial droplet 'VMD' of less than 50 µm at a flow rate of greater than two litres per minute;
b. Spray booms or arrays of aerosol generating units capable of delivering, from a liquid suspension, an initial droplet 'VMD' of less than 50 µm at a flow rate of greater than two litres per minute;
c. Aerosol generating units specially designed for fitting to systems specified by 9A350.a. and b.
Note: Aerosol generating units are devices specially designed or modified for fitting to aircraft such as nozzles, rotary drum atomisers and similar devices.
Note: 9A350 does not apply to spraying or fogging systems and components that are demonstrated not to be capable of delivering biological agents in the form of infectious aerosols.
Technical Notes:
1. Droplet size for spray equipment or nozzles specially designed for use on aircraft, "lighter‑than‑air vehicles" or unmanned aerial vehicles should be measured using either of the following:
a. Doppler laser method;
b. Forward laser diffraction method.
2. In 9A350 'VMD' means Volume Median Diameter and for water‑based systems this equates to Mass Median Diameter (MMD).
9. B.  Test, Inspection and Production
