Mechanically, this Tariff Concession Order (TCO 0716880), made under s.269P of the Customs Act 1901, designates “covers, balloon, radar reflective, silver metallised nylon mesh” (Tariff 5608.19.90) as goods to which Schedule 4 Item 50 of the Customs Tariff Act 1995 applies from 04.10.07 until revoked. The delegate of the Chief Executive Officer signed it. Effect: importers of that narrowly described product may claim the Schedule 4 tariff treatment; customs officials decide eligibility and verification. The measure concentrates a tariff concession on a single classified product and creates administrative compliance and revocation discretion.
