This Order (TCO 1008091) treats “styrene acrylate polymers, in powder or granule form” (tariff classification 3906.90.00) as goods covered by Schedule 4 Item 50 of the Customs Tariff Act 1995 from 15 February 2010 until revoked (made under s.269P of the Customs Act 1901; revocation via ss.269SC/269SD). Mechanically, importers can claim the Schedule 4 concession at import to alter duty treatment; Customs (via delegated officers) decides eligibility and may revoke, so correct classification and import documentation are required to obtain or keep the benefit.
