This Tariff Concession Order applies item 50 in Part III of Schedule 4 of the Customs Tariff Act 1995 to a specified polyester, non‑woven, stitch‑bonded carpet‑backing fabric (tariff classification 6005.31.00), effective 12 November 2010 and continuing until revoked. Mechanically, it changes the customs tariff treatment for imports of that exact fabric. Importers (or their agents) must correctly classify goods and rely on the concession; the delegated officer (the CEO’s delegate) can revoke the order under the cited Act provisions.
