8549 31 00: Containing primary cells, primary batteries, electric accumulators, mercury-switches, glass from cathode-ray tubes or other activated glass, or electrical or electronic components containing cadmium, mercury, lead or polychlorinated biphenyls (PCBs)

1. Subheading 852581 covers only high-speed television cameras, digital cameras and video camera recorders having one or more of the following characteristics:

- writing speed exceeding 0,5 mm per microsecond;

- time resolution 50 nanoseconds or less;

- frame rate exceeding 225000 frames per second.

2. In respect of subheading 852582, radiation-hardened or radiation-tolerant television cameras, digital cameras and video camera recorders are designed or shielded to enable operation in a high-radiation environment. These cameras are designed to withstand a total radiation dose of at least 50 × 10³ Gy(silicon) (5 × 10⁶ RAD (silicon)), without operational degradation.

3. Subheading 852583 covers night vision television cameras, digital cameras and video camera recorders which use a photocathode to convert available light to electrons, which can be amplified and converted to yield a visible image. This subheading excludes thermal imaging cameras (generally subheading 852589).

4. Subheading 852712 covers only cassette-players with built-in amplifier, without built-in loudspeaker, capable of operating without an external source of electric power and the dimensions of which do not exceed 170 mm × 100 mm × 45 mm.

5. For the purposes of subheadings 854911 to 854919, ‘spent primary cells, spent primary batteries and spent electric accumulators’ are those which are neither usable as such because of breakage, cutting-up, wear or other reasons, nor capable of being recharged.
