This order declares that weld test rings (Tariff classification 7304.41.00) that comply with the DNV‑OS‑F101 standard are covered by item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 8 Dec 2005 and continuing until revoked under ss 269SC/269SD. Mechanically, it applies the Schedule 4 tariff concession to those imports; importers therefore receive the Schedule 4 treatment (affecting duty payable), qualification depends on meeting the stated technical standard, and the decision was made under s 269P by a CEO delegate.
