of 3 'effective grams' or less when contained in a sensing component in instruments.
                Technical Note:
                For the purposes of 1C012. Note, 'effective grams' for plutonium isotope is defined as the isotope weight in grams.
b. 'Previously separated' neptunium‑237 in any form.
Note: 1C012.b. does not apply to shipments with a neptunium‑237 content of 1 g or less.
Technical Note:
For the purposes of 1C012.b., 'previously separated' is the application of any process intended to increase the concentration of the controlled isotope.
1. C. 101. Materials and devices for reduced observables such as radar reflectivity, ultraviolet/infrared signatures and acoustic signatures, other than those specified by 1C001, usable in 'missiles', 'missile' subsystems or unmanned aerial vehicles specified by 9A012 or 9A112.a.
Note 1: 1C101 includes:
a. Structural materials and coatings specially designed for reduced radar reflectivity;
b. Coatings, including paints, specially designed for reduced or tailored reflectivity or emissivity in the microwave, infrared or ultraviolet regions of the electromagnetic spectrum.
Note 2: 1C101 does not include coatings when specially used for the thermal control of satellites.
Technical Note:
In 1C101 'missile' means complete rocket systems and unmanned aerial vehicle systems capable of a range exceeding 300 km.
