This Order (made under s.269P of the Customs Act 1901) applies a Schedule 4 tariff concession (Part III, item 50) to imports classified as 3920.10.00: high‑density polyethylene (HDPE) geomembranes at least 6.5 metres wide. It took effect on 30 August 2006 and continues until revoked under the Act. Mechanically, it changes customs duty treatment for importers of those large HDPE geomembranes, creating administrative discretion to revoke and potential effects on import costs and government receipts.
