This Tariff Concession Order (under s.269P of the Customs Act 1901) declares that plastic novelty glasses with coloured shapes on the lenses (classified 9503.00.99) are covered by Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 10 November 2011. Mechanically, that changes the tariff treatment of those imports until the Order is revoked (ss.269SC/269SD). Importers receive the concession; the Commonwealth foregoes corresponding tariff receipts and importers must correctly classify goods to rely on it.
