GST classification change: omission of Schedule entry for prepared wool used in wigs alters tax treatment. Schedule entry 6703, describing wool or other animal hair prepared for use in making wigs, has been omitted, removing that item from the Schedule and altering its statutory tariff positioning; the omission was effected by notification amending the Schedule, with the prior text identifying wool or other animal hair prepared for wig-making preserved as the antecedent description.
