Any company based in Asia that outright refuses Paypal or a credit card payment which allows a chargeback in the event of non receipt of goods would be raising a red flag from the outset for me.

Having said that I have as a last resort used an international SWIFT transfer from my local bank (fee involved which varies from bank to bank) when there is no other option after thoroughly doing a background check on the business I intend to transact with.

The key point is to do due diligence before dealing directly with any company in that region regardless of payment method and by looking at who/what kind of business associations they have had in the last five years.

Company is sound.. ive been getting samples made and sent for free for a while now based on a finalised product and MOQ... well im at the finalised  product and all of a sudden my normal method of payment is no longer.
Im going with my bank in the end and have sent off for a USB token that allows me to transfer.. takes 6-9 working days though for some reason.. guess they are all union or council workers.
Just to add, not many Chinese companies will accept Paypal.. old matey selling his goods on Ebay will as he uses Ebay to enter the Western market.. but a big electronic company in Taipei? Nope.. I had to talk them into accepting WE only to find its all changed.
Also.. when I type FINALISED  I expect it to remain so and not have the S turned into a Z just because its sounds like that in the word... I can spell thank you dumb arse computer ( note: it also turns THAN into THEN.. completely different word).. anyone else find this friggin irritating?
