英语翻译谢谢你提供的信息.我的订单已到达中国.由于此次使用UPS航运,UPS为主动报关,此订单被中国海关查验,现需缴纳约100美元进口关税.若使用USPS航运,则不会被海关查验.我认为此订单所产生的关税需由你们支付.

Thanks for the information you provide.
My order has arrived in China.
Due to the use of UPS shipping, they declarate initiatively, this order has inspected by the Chinese customs , and required to pay approximately $ 100 import tariffs now. If you use the USPS shipping, you need to be inspected.
I think that the tariff in this order should be paid by you.

Thank you for the information.

Due to the use of UPS shipping, UPS to active the customs declaration, this order by the Chinese customs inspection, it now needs to pay about $100 to import duties. If use USPS shipping, it won't be customs inspection.
I think this order is generated by you to pay duties.

My order has arrived in China.
As we konw,this order was delivered by UPS shipping.Due to UPS' active customs clearance,this order was inspected by Chinese Customs.We now need to pay USD 100 as importing duty.
Clearly,it won't be inspected by the Customs if shipped by USPS.
Due to your mistake,i think you should be responsible for the 100$ duty.
其实翻译大同小异,只要让对方明白个中缘由才行,赔偿了您这100美金才是正事儿.强调他们的错误,把责任退给他们.必要时电话打过去!
希望您顺利解决此事儿!

Thanks for your information.

But we were required pay nearly 100 USD for import tax. Because this goods deliveried by way of UPS shippment, and UPS declared actively, so the goods was checked by Chinese custome. If use the way of UPS freight, we can aovid this kind inspection.
In view of above reason, the tax for this goods should be paid by your side.
