This Order (TCO 1130352) declares that silyl‑terminated polyether resins classified at 3907.20.00 are to which item 50 in Part III of Schedule 4 of the Customs Tariff Act 1995 applies, effective 7 Sept 2011. It was made by a delegate of the Chief Executive Officer under s.269P of the Customs Act 1901 (revocation under ss.269SC/269SD). Mechanically, it changes the tariff treatment applied at import, so importers' customs charges and import choices are affected; compliance requires correct classification and monitoring for any revocation.
