As we don’t know China’s law , so sometimes we wonder to purchase all of components together from China, as same time to choice China factory help us to assemble them as whole products ,then ship out to our local place to sell, in that case we can save many time and money , but we really dont choice RMB is good for us or choice USD is good for us.
If this condition , we suggest you can choice RMB make business with China, although you need to pay for tax to China , but it doesn’t matter, once your whole products leaving China, you can contact China customs workers to apply return tax to you. In that case you will not meet many trouble for shipping question .
