If you want to find out the duty and vat rates for things you want to import then go
here ... once there click on the link in the main text that starts
find commodity codes ....
The lower search box on the page that takes you to will allow you to search for just about anything and find out its duty and vat rates (but the results can take some thinking about to work out which is the right thing).
Notes:
- if the value including shipping is < £18 then vat will not be charged
- if the item is marked as a gift that figure rises to £36 (people sometimes claim that doing this means that you don't pay it at all ... this is wrong)
- if the figure for duty comes to < £7 then you probably won't be charged it
- there will likely be an admin fee from what ever company is doing the shipping.
Note if the item is shipped by a courier company, e.g. Fedex, always check the breakdown before paying anything. I've just spent several days sorting out an invoice where an extra £61 charge for shipping had been included during the customs calculation in error, (the shipping had been included in the original total figure) ... I wasn't charged this but it mucked up the vat and duty calculations. I challenged this and have had it removed and the extra vat and duty charges (along with the admin fee) credited back against the invoice
You may be lucky and have the package go through with no charges but you should be prepared to have to pay.
