Thanks for your reply.
To be frank, i do not know how much fee you will pay to the customs, but i can give you two suggestion.
If you purchase the goods less than 10000pcs, i suggest you ship the googs by express, such as DHL, UPS, TNT. they will help you customs clearance, you can save lots of customs clearance fee.
About tax, i can reduce the total value of goods on the document which you used for customs clearance, then you can pay less tax.
Would you mind tell me how much piece you need, then i can offer the shipping fee for you.
