This Order (under s269P of the Customs Act 1901) declares that goods described as INTENSIFIERS, JAR, OIL AND GAS WELL with tariff code 8431.43.00 are covered by Part III Schedule 4 item 50 of the Customs Tariff Act 1995, effective 27 October 2008 and continuing until revoked (ss269SC/269SD).
Mechanically, it changes tariff treatment for importers of those goods; the decision is made by a delegate of the CEO (Damien Beaumont). The stated effect is a Schedule 4 concession; costs include foregone tariff revenue and importers' compliance burdens, and revocation follows the statutory process (ss269SC/269SD).
