the form of tubes or cylindrical solid forms (including forgings) with an outside diameter of more than 75 mm;
b. Titanium alloys having both of the following characteristics:
1. 'Capable of' an ultimate tensile strength of 900 MPa or more at 293 K (20°C); and
2. In the form of tubes or cylindrical solid forms (including forgings) with an outside diameter of more than 75 mm.
Technical Note:
The phrase alloys 'capable of' encompasses alloys before or after heat treatment.

1. C. 210. 'Fibrous or filamentary materials' or prepregs, other than those specified by 1C010.a., b. or e., as follows:
a. Carbon or aramid 'fibrous or filamentary materials' having either of the following characteristics:
1. A "specific modulus" of 12.7 x 106 m or greater; or
2. A "specific tensile strength" of 235 x 103 m or greater;
Note: 1C210.a. does not apply to aramid 'fibrous or filamentary materials' having 0.25 percent or more by weight of an ester based fibre surface modifier.
b. Glass 'fibrous or filamentary materials' having both of the following characteristics:
1. A "specific modulus" of 3.18 x 106 m or greater; and
2. A "specific tensile strength" of 76.2 x 103 m or greater;
c. Thermoset resin impregnated continuous "yarns", "rovings", "tows" or "tapes" with a width of 15 mm or less (prepregs), made from carbon or glass 'fibrous or filamentary materials' specified by 1C210.a. or b.
Technical Note:
The resin forms the matrix of the composite.
Note: In 1C210, 'fibrous or filamentary materials' is restricted to continuous "monofilaments", "yarns", "rovings", "tows" or "tapes".
1. C. 216. Maraging steel, other than that specified by 1C116, 'capable of' an ultimate tensile strength of 1,950 MPa or more, at 293 K (20oC).
Note: 1C216 does not apply to forms in which all linear dimensions are 75 mm or less.
Technical Note:
The phrase maraging steel 'capable of' encompasses maraging steel before or after heat treatment.
1. C. 225. Boron enriched in the boron‑10 (10B) isotope to greater than its natural isotopic abundance, as follows: elemental boron, compounds, mixtures containing boron, manufactures thereof, waste or scrap of any of the foregoing.
Note: In 1C225 mixtures containing boron include boron loaded materials.
Technical Note:
The natural isotopic abundance of boron‑10 is approximately 18.5 weight per cent (20 atom per cent).
1. C. 226. Tungsten, tungsten carbide, and alloys containing more than 90% tungsten by weight, having both of the following characteristics:
a. In forms with a hollow cylindrical symmetry (including cylinder segments) with an inside diameter between 100 mm and 300 mm; and
b. A mass greater than 20 kg.
Note: 1C226 does not apply to manufactures specially designed as weights or gamma‑ray collimators.
1. C. 227. Calcium having
