Thank you so much for the quick reply.

Using EUB, Can i ship products which are not being sold on Ebay?

Is the 7-10 working days guaranteed using EUB to USA?

1. If you are a seller, you can ship what ever product you would like but what guarantee are you giving the buyer's. You need also to take care of the following:

China Post Forbidden Item List

2. Also using EUB if I'm not mistaken it's the term use for Europe. For USA they call that E Packet. E Packet delivery time should be around 6 to 12 working days. Sometimes it's faster and sometimes it's slower, it all depends in which Inbound warehouse it land in USA.

3. Here is a reference about E Packet:

format 4: the number starts with “L” and ends with “CN”, i.e. LK123456789CN, LN987654321CN,LM123456789CN,
This is China Post ePacket parcel. It is almost as faster as EMS and only a little bit more expensive than airmail.
However, ePacket service is only available to limited countries such as USA, Canada, Australia,UK etc.

Hope this help.
