Nevertheless, the parties' agreement to use a particular Incoterm would necessarily have implications for the other contracts.

然而， 各方的协议使用一个特定的国贸条规将必然地为其它合同有含意。

Added wording? It is possible, and in many cases desirable, that the seller and buyer agree to additional wording to an Incoterm.

附加措辞—买卖双方有可能同意在国际贸易术语上附加一些措辞，这在许多情况下是比较理想的。

Unless otherwise agreed, the Seller must provide the documents (if any) indicated in the applicable Incoterm or, if no Incoterm is applicable, according to any previous course of dealing.

除非另有约定，卖方必须提供适用的国际贸易术语中要求的单证(如有的话)，或者如果没有适用的国际贸易术语，则按照先前交易过程确定。
