Firstly, thanks very much for the review!
Huscarle,
In the UK it depends on the declared value of the goods plus postage and also where the goods come from. Below a certain level (about 70 pounds in the UK?) Customs don't charge anything (verify with a search of TMP topics). Above that threshold you become liable for both VAT and duty.
VAT is at 17.5% of the value (or whatever it is in the UK now). This is the major portion of the charge. Duty is much smaller, like a couple of percent (but verify that with a topic search).
The level of duty depends on the country of origin, what documents you have, and how customs feel on that day.
Bangladesh gets duty 100% remission (zero duty) for the EU, USA, Canada, Aus, NZ, etc. etc. But you have to have a GSP (Generalised System of Preferences) certificate with the package. It isn't normally worth doing this unless the value of goods is large as obtaining the certificate is a hassle.
If you are really interested I'll scan the GSP documents for you and let you have a copy. My email address is modartis at gmail dt com (so as to avoid spam I wrote it this way).
As I mentioned, there have been other threads on TMP discussing this for the UK. A search of topics will reveal the threshold for UK customs and more info on duty for painted minis.
Cheers
Neil
