Definition: 

A Classification Item represents a Category at a certain Level within a Statistical Classification.

Explanatory Notes: 

A Classification Item defines the content and the borders of the Category. A Unit can be classified to one and only one item at each Level of a Statistical Classification. As such a Classification Item is a placeholder for a position in a StatisitcalClassification. It contains a Designation, for which Code is a kind; a Category; and other things.

This differentiates it from Code which is a kind of Designation, in particular it is an alphanumeric string assigned to stand in place of a category. For example, the letter M might stand for the category Male in the CodeList called Gender.

Example: 
In the 2012 NAICS (North American Industry Classification System) one Classification Item has the Code 23 and the Category construction.
