Tariff Concession Order 0912668 declares that specific parts — lifting yokes for crane/wind‑turbine towers with a Safe Working Load over 40 tonnes (classification 8431.49.90) — are goods to which the item in Part III of Schedule 4 to the Customs Tariff Act 1995 (item 50) applies, effective 16.04.09 (made under s.269P, Customs Act 1901). Mechanically, it changes the tariff treatment for importers of those parts; the CEO’s delegate lists the goods (s.269P) and the concession can be revoked under ss.269SC–269SD, shifting compliance and cost consequences to importers and customs administration.
