This Tariff Concession Order (TC 0913956) declares that certain copolymers (tariff classification 3903.90.00) with at least 58% methylstyrene acrylate are goods to which Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, effective 24 April 2009 (made under s.269P of the Customs Act 1901 and revocable under ss.269SC/269SD).
Mechanically, the Order changes which tariff treatment importers of these copolymers receive; the CEO’s delegate made the decision and importers must meet the chemical description to qualify.
