签订书面合同应注意的问题
签订书面合同是一项具体、复杂而又特别重要的工作，在操作过程中要特别注意以下几个问题：
（1）要注意合同各条款之间的内在联系。合同是一个有机整体，各个条款之间要相互衔接，保持一致，不应出现相互矛盾的内容。例如，合同中规定采用CIF 术语，同时又规定出口方必须保证货物于×年×月前到达目的港，实际上已经否定CIF 术语的作用，增加了出口方的责任与风险。
（2）合同条款要完善和明确。首先，合同条款一定要订的具体、完善，防止错列和漏列主要事项。其次，合同的文字要简练、严谨、明确，切忌使用模棱两可或含糊不清的词句和文字。
（3）必须符合我国有关法律法规的规定。我国对外签订的任何国际货物买卖合同，都必须遵守我国的法律规定。不符合我国法律规定的合同将被视为无效，不能得到我国法律的承认和保护。
（4）必须贯彻我国的各项对外政策。目前，对外贸易已经成为各国对外关系中一个十分重要的方面，“政治问题贸易化”或“贸易问题政治化”的现象越来越普遍。我国奉行独立自主的对外政策，愿意在和平共处五项原则的基础上发展各国、各地区的经济和贸易关系。为此，对外签订合同必须符合和贯彻我国对外政策与方针。
（5）必须遵守有关国际公约与国际贸易惯例。国际贸易已经超出一国的国内行为，因此，必须接受有关国际公约的约束。目前，《联合国国际货物销售公约》已经成为国际货物买卖方面影响最大的国际公约。我国是《公约》的签字国，理应遵守各项规定，但除我国政府提出保留的意见外，我国对外签订的各项贸易协定、支付协定，以及有关的国际贸易惯例也是对外签订贸易合同应该遵守的规则。
