Tariff Concession Order 1134135 (made under s.269P of the Customs Act 1901) treats imported goods classified 9404.90.00 — pet beds with a textile cover and polyester filling — as subject to item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 11 Oct 2011 and continuing until revoked (ss.269SC/269SD). Mechanically, that changes the import duty treatment for that narrowly described product. Importers capture the tariff effect; the department controls continuation or revocation; accurate HS classification and composition proof are the key compliance points.
