Subject to Note 1 above, parts and accessories for machines, apparatus, instruments or articles of this Chapter are to be classified according to the following rules: a. Parts and accessories which are goods included in any of the headings of this Chapter or of Chapter 84, Chapter 85 or Chapter 91 (other than 8487, 8548 or 9033.00.00) are in all cases to be classified in their respective headings; b. Other parts and accessories, if suitable for use solely or principally with a particular kind of machine, instrument or apparatus, or with a number of machines, instruments or apparatus of the same heading (including a machine, instrument or apparatus of 9010, 9013 or 9031) are to be classified with the machines, instruments or apparatus of that kind; c. All other parts and accessories are to be classified in 9033.00.00. 3. The provisions of Notes 3 and 4 to Section XVI apply also to this Chapter. 4. 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 9013. 5. Measuring or checking optical instruments, appliances or machines which, but for this Note, could be classified both in 9013 and in 9031 are to be classified in 9031. 6. For the purposes of 9021, “orthopaedic appliances” means appliances for: - Preventing or correcting bodily deformities; or- Supporting or holding parts of the body following an illness, operation or injury.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. 7. 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. This Chapter does not cover gas pressure regulators (so called) of the piston or diaphragm type, of a kind used with compressed gas cylinders or reticulated gas pipeline systems, incorporating a pressure reducing valve or the like, whether or not combined with a pressure gauge (8481). 2. For the purposes of 9021.10.42 and 9021.10.49, parts does not include pegs, protectors, eyelets, hooks, buckles, ornaments, braid, laces, pompons or other trimmings (which are to be classified in their appropriate headings) or buttons or other goods of 9606.
