i think the deal's off. There are just too many red flags with sending someone you don't know your name, address, account#, routing # and swift number. There is nothing stopping someone from selling your information and from then using it to steal money from your account. It can also be done via the information on your checks but the swift numbers gives additional electronic withdrawal options...One potential problem is customs. You know it's pau ferro but customs might not be so certain. Another could be the VAT, although that's the purchaser's concern.
As for payment, wait for your bank to provide assurance the money will remain yours.
What shipper will you use? Someone wanted me to send an inexpensive guitar to Malaysia and wanted a particular shipper. Researching the cost cancelled the deal.
