The UK has had something similar since January 1st of this year.
VAT (and Duty if applicable) is taxed on the value of Goods and Shipping, unless the item is a Gift valued at £39 or less.
With Goods valued under £135 the seller is supposed to collect tax, and be registered for VAT with the UK so they can repay it.
With Goods worth more than £135 the VAT is payable by the customer to the delivery company either before the goods are delivered or when you collect them.
Customs Duty is charged on all goods sent from outside the UK if they're worth more than £135, and is applicable to the price paid for the goods and postage, packaging and insurance.
