9A010Specially designed components, systems and structures, for launch vehicles, launch vehicle propulsion systems or "spacecraft", as follows:

N.B. SEE ALSO 1A002 AND 9A110.
a. Components and structures, each exceeding 10 kg and specially designed for launch vehicles manufactured using any of the following:
1. "Composite" materials consisting of "fibrous or filamentary materials" specified in 1C010.e. and resins specified in 1C008 or 1C009.b.;
2. Metal "matrix" "composites" reinforced by any of the following:
a. Materials specified in 1C007;
b. "Fibrous or filamentary materials" specified in 1C010; or
c. Aluminides specified in 1C002.a.; or
3. Ceramic "matrix" "composite" materials specified in 1C007;
Note:
The weight cut-off is not relevant for nose cones.
b. Components and structures, specially designed for launch vehicle propulsion systems specified in 9A005 to 9A009 manufactured using any of the following:
1. "Fibrous or filamentary materials" specified in 1C010.e. and resins specified in 1C008 or 1C009.b.;
2. Metal "matrix" "composites" reinforced by any of the following:
a. Materials specified in 1C007;
b. "Fibrous or filamentary materials" specified in 1C010; or
c. Aluminides specified in 1C002.a.; or
3. Ceramic "matrix" "composite" materials specified in 1C007;
c. Structural components and isolation systems, specially designed to control actively the dynamic response or distortion of "spacecraft" structures;
d. Pulsed liquid rocket engines with thrust-to-weight ratios equal to or more than 1 kN/kg and a 'response time' of less than 30 ms.
Technical Note:
For the purposes of 9A010.d., 'response time' is the time required to achieve 90 % of total rated thrust from start-up.
