This Tariff Concession Order (TCO 0604028) declares that specific moisture‑protection sacks — with circular or oval bases, tape‑sealed seams and roll‑top closures — are goods to which item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies from 17 February 2006 until revoked. It affects importers (who receive the tariff treatment) and the Commonwealth (which forgoes tariff revenue); it is declared by a CEO delegate under s269P and requires import documentation matching the classification.
