What this does: Declares that "VALVES, ULTRA HIGH VACUUM (UHV)" (tariff 8481.80.90) are covered by Schedule 4, Part III item 50 of the Customs Tariff Act 1995, effective 10.05.05; the order was made by a delegate under s.269P and continues until revoked under ss.269SC or 269SD of the Customs Act 1901.
Who it affects and why it matters: Importers of these valves can access the Schedule 4 concession; importers benefit and the government forgoes tariff revenue. Eligibility depends on correct customs classification and paperwork; the agency may revoke the concession.
