Question

请大家帮我翻译下下面这段话 ，用英语，不要机器，可以让客户明白意思。我是做油画的。，很急 拜托大家了

（客人的画到达他们公司，产生了额外的关税费用，只有他们交了关税的费用才能拿到画）
亲爱的朋友：
我们已经和快递公司联系了，TNT不是要多收两次费用，而是画到达贵国的时候产生了额外关税费用，TNT公司已经帮你们把关税交了，所以他们要收取您关税的费用。

Answer 1

Dear XXX,

We have checked with TNT, and the extra cost is not charged by TNT. The cost is for the import tax of the Custom of your country. The TNT paid the tax first during the import process, then TNT has to charge this tax on you. Thanks for understanding.

Answer 2

Dear friends,
We have already contacted the express company to find out what happened. And the fact is that the customs duties when entering your country took extra costs. TNT has paid for it for you, so you should give it money accordingly.
