AS IS条款是指卖方在出售货物时按照交付时货物的现状交付货物。AS IS条款常见于二手货物买卖合同（包括不动产、船舶等）以及商业财产租赁合同。在英美法系中，对AS IS条款的理解需把握三点：（一）如无特别约定，以交货时的货物现状为准，而非合同订立时的货物状态。（二）该条款属于典型的“脱责条款”（disclaimer clause），核心是卖方脱责，即卖方对其出售货物质量等不作任何保证，由买方对货物质量等承担所有风险。《美国统一商法典》明确规定，AS IS条款可以排除卖方的默示担保责任。（三）责任承担的例外。即便《美国统一商法典》规定可以排除卖方的默示担保责任，但这种排除也有一定限度。

另附上美国Uniform Commercial Code §2-316 Exclusion or Modification of Warranties (2) and (3)（《美国统一商法典》第2-316条 排除或修改担保 第（2）和（3）款）：

(2) Subject to subsection (3), to exclude or modify the implied warranty of merchantability or any part of it the language must mention merchantability and in case of a writing must be conspicuous, and to exclude or modify any implied warranty of fitness the exclusion must be by a writing and conspicuous. Language to exclude all implied warranties of fitness is sufficient if it states, for example, that “There are no warranties which extend beyond the description on the face hereof.”

在本条第（3）款的规限下，如排除或修改有关适销性的默示担保或其任何部分，用语必须提及适销性；如以书面形式作出，其书写必须醒目。如排除或修改有关适用性的任何默示担保，须以书面形式方得排除，且书写必须醒目。如完全排除有关适用性的默示担保，应采用“除商品外部描述外，无其他任何担保”之类的词句。

(3) Notwithstanding subsection (2)

尽管存在上述第（2）款的规定

(a) unless the circumstances indicate otherwise, all implied warranties are excluded by expressions like “as is”, “with all faults” or other language which in common understanding calls the buyer’s attention to the exclusion of warranties and makes plain that there is no implied warranty; and

除非情况另有表明，如明确表示“依现状”、“不保证商品无瑕疵”，或其他根据通常理解可使买方注意到卖方排除担保且表明无默示担保的用语，可排除所有默示担保；且

(b) when the buyer before entering into the contract has examined the goods or the sample or model as fully as he desired or has refused to examine the goods there is no implied warranty with regard to defects which an examination ought in the circumstances to have revealed to him; and

如果买方在签订合同之前已经完全按其自身的意愿检验过货物或样品或模型，或买方拒绝检验货物，则对于买方通过检验应该发现的瑕疵，卖方不作默示担保；且

(c) an implied warranty can also be excluded or modified by course of dealing or course of performance or usage of trade.

如有交易惯行或履约惯行或行业惯例，亦可排除或修改默示担保。
