on behalf of the petitioner is that, as the words “MDF boards” were inserted into Entry 17 of the VI Schedule with effect from 01.08.1996, and Entry 114 of the First Schedule remained unamended, it was evident that, prior to 01.08.1996, MDF Boards were taxable only as general goods under the VII Schedule, and not under Entry 114 of the First Schedule to the Act. As has been noted by the Tribunal, the process involved in manufacture of MDF Boards is to cut wood, in its natural form, into small chips/particles on a suitable chipping machine; these wood chips are steamed and defibrated in a suitable defibrating machine; the wood fibre, so produced, is dried in flash dryers, and is blended with resin and wax; the blended fibres are formed into mats by air felting; and are pressed into panels by passing them through a pressing machine under controlled heat, pressure and time conditions.

After the amendment of Entry 17 of the VI Schedule by Act 27 of 1996, MDF Boards are liable to be taxed thereunder, and not under Entry 114 of the First Schedule. However prior to Act 27 of 1996, as the MDF Boards manufactured by the petitioner were made out of wood
