装运前检验(PRE-SHIPMENT INSPECTION 简称PSI)，又叫装船前检验。是由专门检验机构对出口产品的数量、质量、价格、重量、唛头、安全、卫生、环保等项目在出口方境内进行的所有装运前的检验活动，同时还要实施价格核查和监视装载。

出口埃及、孟加拉等国家需要做装船前检验。在孟加拉的信用证LC中，都会规定如下PSI检验条款：
PRESHIPMENT INSPECTION FOR QUANTITY,QUALITY,DESCRIPTIONS,
CLASSIFICATIONS AND PRICE SHOULD BE CARRIED OUT BY BIVAC INTERNATIONAL SA. OR SGS
ONE ORIGINAL INVOICE AND ONE ORIGINAL PACKING LIST SHOULD BE ENDORSED BY
BIVAC INTERNATIONAL SA OR SGS WITH THE NUMBER AND DATE OF ISSUANCE OF CRF.
