# 请问PI里面的M/S是什么意思？

## 问题

 我刚入行，给客户做形式发票(PI)时，看到有个M/S栏目，客户也问我要M/S信息。请问这个M/S到底是什么意思？该怎么填？ 

## 回答
                            
### 回答 1 — 最佳答案

M/S在贸易单证中通常指唛头（Marks and Numbers），是海关监管和货物识别的重要依据。从合规角度看，您必须确保PI上的M/S信息与后续报关单、提单、装箱单完全一致，否则可能面临海关查验延误、改单罚款甚至影响退税。如果货物无唛头，应明确填写“N/M”（No Marks），切勿留空。特别提醒，若涉及品牌货物，唛头中的品牌标识必须与知识产权备案一致，避免侵权风险。

M/S就是唛头，直接决定了货物在仓库和运输过程中的识别效率。实操中，您需要把M/S信息同步给货代，用于制作提单和舱单。如果是整柜，唛头可以简单些；如果是拼箱，唛头必须清晰准确，否则目的港拆柜会出问题。建议格式：收货人简称+目的港+件数编号。另外，现在很多船公司要求M/S信息在订舱时就提供，晚了可能产生改单费，一个字母错了改单就是几百块。

M/S是向客户展示您专业度的细节点。在PI里，您可以把唛头信息单独列明，并邮件告知客户：“附件PI中M/S栏已按贵司要求填写，请确认唛头格式是否符合目的港清关要求”。这样既显得专业，又把责任明确化。如果客户没指定唛头，您要主动提供方案供其确认，避免后续纠纷。记住，M/S信息一旦确认，所有单据必须保持一致，这是客户评估您操作专业性的关键指标，直接影响后续付款意愿。
