1. For the purposes of heading 9001, the expression 'optical fibres, optical fibre bundles and cables' means optical fibres, optical fibre bundles and cables of glass or plastics, consisting of individually sheathed fibres, whether or not assembled with electrical conductors or fitted with connectors. 2. For the purposes of subheading 9013 20 00, 'lasers' includes laser diodes but does not include laser diode assemblies of heading 8541. 3. For the purposes of heading 9025, 'hydrometers and similar floating instruments, thermometers, pyrometers, barometers, hygrometers and psychrometers' include those combined with recording devices but do not include those combined with any other instrument (for example: thermo-hygrographs combining a thermometer and hygrometer). 4. For the purposes of heading 9031, 'profile projectors' means instruments which project a magnified silhouette of a workpiece on to a screen so that the accuracy of the profile may be verified. This term does not include other optical projectors (heading 9008 or 9010).
This chapter does not cover: articles for general technical purposes (e.g. pumps of heading 8413, metal or graphite packings of heading 8484), parts of general use as defined in Note 2 to Section XV (base metal) or similar parts of plastics (Chapter 39), transfer pumps of heading 8413, or weighing machinery of heading 8423. Note 2 (Parts and accessories): Parts and accessories which are goods included in any heading of this chapter or of Chapter 84, 85 or 91 are classified in their respective headings. Other parts and accessories solely or principally used with instruments of this chapter are classified in heading 9033. The chapter covers a very broad range from lenses and prisms (heading 9001) through microscopes, telescopes, lasers, navigational instruments, drawing instruments, measuring instruments, medical instruments, to X-ray apparatus and physical/chemical analysis instruments.
1. This Section does not cover: (a) articles of a kind used in machines, appliances or for other technical uses, of vulcanised rubber other than hard rubber (heading 4016), of leather or of composition leather (heading 4205) or of textile material (heading 5911); (b) supporting belts or other support articles of textile material whose intended effect on the organ to be supported or held derives solely from their elasticity (for example, maternity belts, thoracic support bandages, abdominal support bandages, supports for joints or muscles) (Section XI); (c) refractory goods of heading 6903; ceramics for laboratory, chemical or other technical uses of heading 6909; (d) glass mirrors, not optically worked, of heading 7009, or mirrors of base metal or of precious metal, not being optical elements (heading 8306 or Chapter 71); (e) goods of heading 7007, 7008, 7011, 7014, 7015 or 7017; (f) parts of general use, as defined in Note 2 to Section XV, of base metal (Section XV) or similar goods of plastics (Chapter 39); however, articles specially designed for use exclusively as parts of specific instruments or apparatus are excluded from this category; (g) pumps, compressors and fans (heading 8413, 8414 or 8421); (h) weighing machinery (heading 8423); lifting machinery (headings 8425 to 8428); (ij) paper- or paperboard-cutting machines (heading 8441); fittings for adjusting work or tools on machine tools or water-jet cutting machines, of heading 8466, including fittings with optical devices for reading scales (e.g. 'optical' dividing heads) but not those which are in themselves essentially optical instruments (e.g. alignment telescopes); (k) articles of Chapter 95. 2. Subject to Note 1 above, parts and accessories for machines, apparatus, instruments or articles of this Section are to be classified according to the following rules: (a) parts and accessories which are goods included in any of the headings of this Section or of Section XV, XVI or XVII 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, are to be classified with the machines, instruments or apparatus of that kind; (c) all other parts and accessories are to be classified in heading 9033.
