@xxCDxx,
The customs issue is always there. It depends on the policy in your local customs. Some time the customs will inspect the goods very strictly. They will charger you the money if they find that the value declared is much lower than the real value of the goods. But sometimes everything is going through very well from the customs. So no body can gerantee this.
The usual doing is to select a shipping like register air mail- Singapore or Hongkong register air mail. Parcels via post get less rate being inspected by the customs. In this way, you may avoid the customs fee.
For shipping like DHL/ EMS/ UPS and other Express way, it is high rate by checking by your local customs. The customs will charge you the taxes according to the price that written on the DHL shipping bill. But it changed sometimes if they consider the real value is more than the price that written on the bill. In this case, they will require you to pay more money if you want to get it.
What Willgoo will do is that we will declare a low price for every parcel and send as gifts. This is a good way to avoid detecting by the customs. Or we will declare the price like our customers require. But we will not suggest to declare a very low price when we send expensive goods like JXD S7800B, JXD S7300 ect.
No one know what the customs will do. What we do is try our best to help the customs avid high taxes.
