This Tariff Concession Order, made under s.269P of the Customs Act 1901, applies item 50 of Part III of Schedule 4 to the Customs Tariff Act 1995 to goods classified at tariff heading 9508.90.00 — “water slides and/or chutes, amusement park” — effective 22 February 2010 and continuing until revoked under ss.269SC or 269SD or an expiry date in Column 2. Mechanically, importers of those water slides can rely on the Schedule 4 concession (affecting customs duty), which lowers import costs and changes competitive incentives for suppliers and park operators.
