This Tariff Concession Order designates a specific class of reverse‑cycle air conditioners as eligible for a tariff concession by applying Schedule 4 item 50 to goods that meet listed technical thresholds (cooling 1,910–2,900 W; heating ≥1,800 W; airflow ≥84 L/s; moisture removal ≥0.7 L/hr), effective 23 Nov 2010 until revoked. Importers of qualifying goods may claim the concession but must prove compliance; the Chief Executive Officer’s delegate administers the order and may revoke it under ss.269SC–269SD, which affects import costs and sourcing choices.
