This Tariff Concession Order (TCO 0903794) declares that thermoplastic‑encapsulated subsea umbilicals for chemical injection and hydraulic fluid, of continuous length at least 500 m (customs classification 7304.41.00), fall under item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, with effect from 05.02.2009.
That makes those imported goods eligible for the Schedule 4 concession; it principally affects importers and their suppliers, requires accurate product description and tariff classification, and remains in force until formally revoked.
