Chapter notes
- This Chapter does not cover: (a) Millstones, grindstones or other articles of Chapter 68; (b) Machinery or appliances (for example, pumps) of ceramic material and ceramic parts of machinery or appliances of any material (Chapter 69); (c) Laboratory glassware (heading 70.17); machinery, appliances or other articles for technical uses or parts thereof, of glass (heading 70.19 or 70.20); (d) Articles of heading 73.21 or 73.22 or similar articles of other base metals (Chapters 74 to 76 or 78 to 81); (e) Vacuum cleaners of heading 85.08; (f) Electro-mechanical domestic appliances of heading 85.09; digital cameras of heading 85.25; (g) Radiators for the articles of Section XVII; or (h) Hand-operated mechanical floor sweepers, not motorised (heading 96.03).
- A machine or appliance which answers to a description in one or more of the headings 84.01 to 84.24 (or heading 84.86) and at the same time to a description in headings 84.25 to 84.80 is to be classified under the appropriate heading of the former group (84.01-84.24 or 84.86), not the latter. Exceptions: 84.19 does not cover germination plant/incubators (84.36), grain dampening machines (84.37), diffusing apparatus for sugar juice (84.38), machinery for heat-treatment of textiles (84.51), or machinery where temperature change is subsidiary. 84.22 does not cover sewing machines for closing bags (84.52) or office machinery (84.72). 84.24 does not cover ink-jet printing machines (84.43) or water-jet cutting machines (84.56).
- For the purposes of heading 84.71, 'automatic data processing machines' means machines capable of: (i) storing the processing program and data immediately necessary; (ii) being freely programmed by the user; (iii) performing arithmetical computations specified by the user; and (iv) executing, without human intervention, a processing program which requires modification by logical decision during processing. Units are part of ADP systems if solely/principally used in such systems, connectable to the CPU, and able to accept/deliver data in system-usable form. Separately presented units classified in 84.71. 84.71 does not cover (when presented separately): printers, copying/facsimile machines; transmission/reception apparatus; loudspeakers and microphones; television/digital cameras and video recorders; monitors and projectors not incorporating television reception apparatus.
- Heading 84.82 applies, inter alia, to polished steel balls, the maximum and minimum diameters of which do not differ from the nominal diameter by more than 1% or by more than 0.05 mm, whichever is less. Other steel balls are to be classified in heading 73.26.
