Mechanically, this Tariff Concession Order (TCO 0609749) declares that certain plastic "blanks, seal" goods (materials: polyurethane, polyacetal, polyamide, PTFE, PAEK) classified at 3926.90.90 are subject to item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 7 June 2006. The declaration was made by a delegate under s.269P of the Customs Act 1901 and continues until revoked under ss.269SC/269SD.
Practically, importers of these specific seals must apply the specified tariff concession when importing these classified goods; the order creates an administrative entitlement to a Schedule 4 treatment (requiring correct classification and claiming) and leaves revocation and discretion to the customs delegate (s.269P; ss.269SC–269SD).
