This Tariff Concession Order declares that certain bifold-door fittings—carrier sets, drop bolts and handles, classified at 8302.41.00—are eligible for the Part III Schedule 4 concession (item 50), effective 18 November 2008 until revoked. Importers of those specific goods can claim the tariff concession; the decision is recorded by a delegate of the Chief Executive Officer. The practical effects are reduced or nil tariff on these imports, a revenue consequence for government, and an administrative compliance task for importers to claim and justify the classification.
