The concordance of the North American Industry Classification System (NAICS) 2007 to the International Standard Industrial Classification of all Economic Activities Revision 4 (ISIC Rev. 4) is shown in the table below. The table shows the Canadian interpretation of the relationships between the two classifications.
The concordance is shown at the lowest level of both classifications, namely at the 6-digit level in NAICS and the 4-digit level in ISIC except in the case of three ISIC classes being linked to 3-digit ISIC codes, where more precise links to ISIC are not possible.
The relationships between the two classifications can be simple or complex. The following examples are presented to illustrate how the table should be read.
In the first example, a NAICS class links exactly to one ISIC class, their coverage of activities being the same. All of the activities in NAICS 212210 are found in ISIC B0710.
| NAICS 2007 | ISIC Rev. 4 | ||
|---|---|---|---|
| 212210 | Iron Ore Mining | B0710 | Mining of iron ores |
In the second example, each NAICS class links to a portion of the same ISIC class. Each of NAICS 311320, 311330 and 311340 is a subset of ISIC C1073.
An asterisk attached to the ISIC alpha-numeric code indicates that a NAICS class is equal to a portion of an ISIC class. The explanatory note provides a short description of the nature of the overlap between the NAICS and ISIC classes.

|---|---|---|---|---|
| 311320 | Chocolate and Confectionery Manufacturing from Cacao Beans | C1073 * | Manufacture of cocoa, chocolate and sugar confectionery | Chocolate and confectionery, manufacturing from cacao beans |
| 311330 | Confectionery Manufacturing from Purchased Chocolate | C1073 * | Manufacture of cocoa, chocolate and sugar confectionery | Confectionery, manufacturing from purchased chocolate |
| 311340 | Non-Chocolate Confectionery Manufacturing | C1073 * | Manufacture of cocoa, chocolate and sugar confectionery | Non-chocolate confectionery manufacturing (e.g., lozenges, chewing gum) |
In the third example, a NAICS class is equivalent to more than one ISIC class. NAICS 115210 is equal to ISIC A0162 plus a portion of ISIC M7500.
