  • 3. The provisions of notes 3 and 4 to Section XVI apply also to this chapter.
  • 4. Heading 9005 does not apply to telescopic sights for fitting to arms, periscopic telescopes for fitting to submarines or tanks, or to telescopes for machines, appliances, instruments or apparatus of this chapter or Section XVI; such telescopic sights and telescopes are to be classified in heading 9013.
  • 5. Measuring or checking optical instruments, appliances or machines which, but for this note, could be classified both in heading 9013 and in heading 9031 are to be classified in heading 9031.
  • 6. For the purposes of heading 9021, the expression "orthopaedic appliances" means appliances for: Orthopaedic appliances include footwear and special insoles designed to correct orthopaedic conditions, provided that they are either (1) made to measure or (2) mass-produced, presented singly and not in pairs and designed to fit either foot equally.
    • - preventing or correcting bodily deformities; or
    • - supporting or holding parts of the body following an illness, operation or injury.
  • 7. Heading 9032 applies only to:
    • (a) instruments and apparatus for automatically controlling the flow, level, pressure or other variables of liquids or gases, or for automatically controlling temperature, whether or not their operation depends on an electrical phenomenon which varies according to the factor to be automatically controlled, which are designed to bring this factor to, and maintain it at, a desired value, stabilised against disturbances, by constantly or periodically measuring its actual value; and
    • (b) automatic regulators of electrical quantities, and instruments or apparatus for automatically controlling non-electrical quantities the operation of which depends on an electrical phenomenon varying according to the factor to be controlled, which are designed to bring this factor to, and maintain it at, a desired value, stabilised against disturbances, by constantly or periodically measuring its actual value.

Additional notes

  • 1. For the purposes of subheadings 90153010, 90258040, 90261021, 90261029, 90262020, 90268020, 90271010 and 90321020, the expression "electronic" means instruments and apparatus which incorporate one or more articles of heading 8540, 8541 or 8542 but for the purposes of the foregoing, no account shall be taken of articles of heading 8540, 8541 or 8542 which have solely the function of rectifying current or which are included in the power pack of instruments or apparatus.
  • 2. For the purposes of subheading 90211010, the expression "orthopaedic appliances" means appliances which are specially designed for a particular orthopaedic purpose, in distinction to products that might be used for various purposes (for example, products for overstrained joints, ligaments or tendons caused by sporting activities, type writing, and products which simply alleviate pain in the defective or disabled part of the body, for example, caused by inflammation). The "orthopaedic appliances" must completely prevent a specific movement of the defective or disabled part of the body (for example, joints, ligaments, tendons) in order to exclude further injuries or bodily deformities or an aggravation of such injuries or deformities, as distinct from other products that cannot prevent specific movements, yet prevent reflex movements (movements carried out subconsciously) through the relative inflexibility of those products due to, for example, flexible splints, pressure pads, non-elastic textile material, restrictions through "Velcro-type" straps".
