I would send the buyer an email restating the terms of the sale and ask them to respond whether if they agree or not so you can have as a reference if they complain or what not.
If you're still not totally sure and you are still confused about what you should do, you need to contact eBay Customer Service and they can advise you on what should be done.
I did that already. this was our correspondence:
I think you do not understand what I am trying to explain to you.
I cannot charge you a tax. However, your country's Customs
Agency will inspect the item once imported into your country.
They may also charge taxes and fees for the imported item. Now
before I send you an invoice, do you understand that 1) I (the
seller) will NOT mark the item as "gift" at exportation 2) the item
MAY be subject to inspection upon importation into your country
3) you MAY be charged additional Custom's fees and taxes which
I (the seller) am NOT responsible for 4) the item MAY remain in
possession of your country's Customs Agency for an undisclosed
amount of time (they might hold the item until it passes
inspection). If you do not understand or agree to any of these
terms. I will be forced to terminate the transaction.
and her response.....
Thanks for your help and concern. For the tax fees i have totally understand your question, coz i have already check through my local custom tax fess information of the amount that i have to pay. the only different is that the invoice of the goods have to pasted outside of the parcel that will be easy for me to collect from my door step, you can also chose not to show out the invoice by puting inside the parcel, then i need to go down to my local post personal to collect it.
pls let me know will you provide me the original receipt,dustbag,box a upon delivery
... all I ask of her is that she writes "yes I understand that I (the buyer) am responsible" but for some reason, I don't convey that message from her response.... And as for the "invoice" I think she thinks that if I put the invoice on the package, it will not go through customs, and If I place it inside the box, it will be inspected. So that's why I don't think she understands that all items imported into a country must pass through customs. A few e-mails followed this one. In the last one i sent her, I plain out asked her if she is confusing "invoice" (business invoice) with "customs forms/invoice" No response as of yet.....
