感谢!附件回答的非常详细!
另外,想请教一下在2007年及以前的表格中,部分hs码前有“ex”,请问这个ex ...
它第一个表是世界海关组织指定hs编码时提供的新旧对应关系表,根据WCO的阐述:The left-hand column of Table I refers to the HS 2007 code numbers whose scope has been changed compared with HS 2002, or which have been introduced as new entries. The centre column contains the corresponding HS 2002 code numbers, and may be preceded by .ex.. This prefix indicates that the corresponding HS 2007 entry contains only part of the referenced subheading. For example, new subheading 0301.94 contains a part of the HS 2002 code number 0301.99, which is, therefore, preceded by .ex.. The other part of HS 2002 code number 0301.99 is covered by new subheading 0301.95 or remains in subheading 0301.99. 应该是n:1的时候会多上这样一个前缀
