A few I know of:

Luxury cars 100%
Motorcycles 30% (But likely nearer 70% in the end, and new bikes only)
Bicycles and bicycle parts 20%
Most things 10%

Can I ask a few questions or try to pool some more knowledge on this? Are paying import taxes on things a lottery? I've had maybe 25 cartons delivered, 10 commercial and 15 from friends and family. However I've only ever paid import tax on a bicycle frame that was sent in commercially at 20% tax. This came in via EMS earlier this month. Now I've got a friend being hit for tax on a games console this time coming in via DHL. Should tax be paid on everything new? Are they just pulling random cartons that look commercial and letting the rest slide? Is this going to be a continuing more regular problem?
