Customs tariff amendments withdraw nonactionable subsidy exemptions and revise schedules affecting tariff rates and export duties. Clause 108 removes the exemption for three categories of nonactionable subsidies from antisubsidy investigations under section 9(3)(c), expanding investigatory scope. Clauses 109 and 110 amend tariff schedules: Clause 109 revises First Schedule tariff rates and harmonises entries with the Harmonised System (including Chapter 98 amendments); Clause 110 amends the Second Schedule to impose a specified export duty on the tariff item for other aluminium ores and concentrates.
