Bringing things to donate

The publication that you referenced also includes language that says "Air and sea travelers may bring additional items not exceeding the US$300.00 worth of goods -or its equivalent in other currencies per member of the family".

Seems easier to buy them in Z, but if you have to bring them from the US, you could limit the total value to $300 per person. Just remember to bring receipts to substantiate the total cost. We have done that with household items before and we have never even been asked to show a receipt, even after getting the red light and having our bags searched.

Would they really confiscate them anyway? Instead, wouldn't they just assess you with the apppropriate fees/taxes?
