This Order declares that certain heat‑pump parts (condensers; tariff heading 8418.99.00) are to which Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, effective 15 March 2010 — i.e. it changes how those imported goods are treated under the tariff schedule. The declaration was made by a delegate under s269P of the Customs Act 1901 (Paul Mercer) and remains until revoked under ss269SC–269SD. Importers must correctly classify and document goods to rely on this treatment; revocation and administrative discretion are governed by the cited sections.
