If additional risks are to be covered, the extra premium is for buyer’s ________.

执事先生：

我们按时收到了由“东风”号运来的货。对于你方迅速执行定单，深表谢意。

经检查第3号箱子内所装货物完全不对。我们猜想是货物错装了，箱子内的货物属于别的定单。

由于需用所定货物来完成对我们客户的交货，务请更换，立即发运。随函附上第3号箱货物清单一份，请与我方定单核对。

盼复。

此致

我们已经在“海河”号货船上定了货仓。

货物短交1,540公斤。

如果没有你们的明确指示，我们将按惯例投保水渍险和战争险。

这些货花了我们一百万美元。

该定单以我们获得进口许可证为条件。

Our offer is based on reasonable profit margin.

We shall appreciate it very much if you can accept Documents against Payment terms.

Please make sure the terms in the L/C are exactly the same as those in our contract so that there is no need for amendment, which is costly and time consuming.

If you insist on your price, we will have no way but to turn to other sources for supply.
