I've already received some feedback that 8471503000 (which is an INTERNATIONAL harmonized code) is indeed zero rated for import duty, and only GST will be charged.

If anyone in Australia experiences anything to the contrary I'd be interested to hear of it.

Well, I'm currently having fun with Customs in Melbourne. The package got from empeg to Melbourne in 2 days, which is pretty damn good. For the past four days it's been sitting in Customs while they try and figure out what it is.

Ah well.

Richard.
