This Tariff Concession Order (made under s.269P of the Customs Act 1901) declares that wedge‑shaped, high‑density polyethylene door stoppers (tariff line 3926.90.90) are covered by Part III, Schedule 4 item 50 of the Customs Tariff Act 1995. It took effect 25 November 2009 and remains until revoked (ss.269SC/269SD). Importers gain the changed duty treatment; the delegate of the Chief Executive Officer decided the concession. Claiming it requires correct classification and paperwork, which alters import behaviour relative to local sourcing.
