Tariff Concession Order 0829416 declares that imported programmable logic‑controlled spray booths with powder recovery systems (classified at 8424.89.90) are subject to Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 from 03.09.2008 until revoked under sections 269SC/269SD. Mechanically, it makes those specific imports eligible to claim the Schedule 4 concession specified in Item 50. This affects importers (who may claim the concession) and the Commonwealth (which forgoes the tariff revenue); the CEO’s delegate decides under s269P, and importers must meet the goods description and classification to claim it.
