This Tariff Concession Order makes imported goods described as “parts, oil and/or gas well, being lubricated fishings sub‑assemblies” (tariff heading 8431.43.00) eligible for concession item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 17 December 2009. It reduces tariff costs for importers and shifts administration to the Customs delegate who issued the order under s.269P; the order stays in force until revoked under ss.269SC or 269SD, so importers must ensure correct classification and watch for revocation.
