贸易是根据品质(Quality),价格(Price),装船期(Shipping Time)或交货期(Time Ofdelivery)三要素,来决定是否成立,其重要性可想而知.其中品质决定交易的价值,因而被认为是最重要的交易因素.

    品质决定法:品质的决定有依据样品的买卖方法,称为凭样品买卖(Sale by Sample).其他有设定标准品质,以此标准品质为蕨来做的方法,称为凭标准品买卖(Sale by Standard). 另外,在工业制品方面,用数字等资料标明性能和重量而作成的规格书,依据此书来做买卖,称为凭规格书买卖(Sale by Specification). 又有一种指定世界著名品牌的买卖,称为凭品牌买卖(Sale by Brand).
