The answer is NO, NOT ALWAYS... because your order value may be much higher than this and declaring that low value would not be feasible.

Provided the value of your order / type/ quantity of the items is suitable for a declaration under $50, we will do our best to help you with this. 

If you need advice about whether a particular declared value is deemed possible, before you pay, you can check out an order and contact customer service with your order number. We will then look at the contents of your order and your country and assess what declared value is sensible.
