Statistical classification only
Statistical classification only. This guide does not determine any reader's code. Confirm a code with the national statistical institute or the business register that holds the record. This is general information, not advice on any reader's registration.
Manufacturing changes in NACE Rev. 2.1 are listed in the manual passage on Section C, covering divisions 14, 16, 20, 22, 25, 26, 28, 30 and 31. The changes include rearrangements of groups, splits of classes, mergers of classes, restructurings of groups, and creations of new classes. Minor changes, such as heading changes at group and class level, renumbering, recoding and partial transfers, are not listed there. This guide therefore covers only the major changes listed for manufacturing, and it does not present the list as a complete record of every manufacturing change.
Which groups were rearranged or restructured?
Division 14 for manufacture of wearing apparel was rearranged. Groups 14.1, 14.2 and 14.3 in NACE Rev. 2 were rearranged into two new groups in NACE Rev. 2.1: 14.1 for manufacture of knitted and crocheted apparel, and 14.2 for manufacture of other wearing apparel and accessories. Group 25.6 for treatment and coating of metals and machining was restructured, and group 26.8 for manufacture of magnetic and optical media was integrated into group 26.7 for manufacture of optical instruments, magnetic and optical media and photographic equipment. Group 31.0 for manufacture of furniture was restructured by merging four classes into one new class, 31.00 for manufacture of furniture. Those rearrangements change the group structure inside the divisions, and the correspondence table must be checked for the classes inside each affected group.
The rearrangements share a pattern: fewer, broader groups in some places, with the detail carried at class level, and integration of a small group into a neighbouring group where the activities are closely related. The manual does not state a single reason for every rearrangement, and this guide does not add one. Each rearrangement is stated in the manual passage with its old and new group numbers and headings, and the reader must use those numbers and headings, together with the correspondence table, to trace a class through the change.
| Division | Change stated in the manual |
|---|---|
14 | Groups 14.1 to 14.3 rearranged into new groups 14.1 and 14.2 |
25 | Group 25.6 restructured |
26 | Group 26.8 integrated into group 26.7 |
31 | Group 31.0 restructured, four classes merged into class 31.00 |
Which classes split, and which merged?
Several manufacturing classes split. Group 16.1 split into classes 16.11 and 16.12. Class 16.29 split into three new classes: 16.26, 16.27 and 16.28. Class 16.23 split into two new classes: 16.23 and 16.25. Class 20.59 split into 20.51 and 20.59, with the content of former classes 20.51, 20.52 and 20.53 moved into the new class 20.59. Class 22.23 split into three new classes: 22.23, 22.24 and 22.25. The manual gives the full headings for each new class in the passage, and the headings must be read there, because a split class that keeps an old number, such as 16.23 or 20.59, may have a different scope in the new version from the scope it had in the old version.
Several manufacturing classes merged. Classes 25.21 and 25.30 merged into a new class 25.21 for manufacture of central heating radiators, steam generators and boilers. Classes 31.01, 31.02, 31.03 and 31.09 merged into class 31.00 for manufacture of furniture. A merger in the correspondence table is a many to one relationship, where the joint scope of the old classes is the scope of the new class, subject to the notes. A split is a one to many relationship, where the old scope is divided among the new classes, and the notes for each new class state which part of the old scope it covers. Neither relationship, on its own, picks a new class for a specific activity. The notes must be read, and the entry must be confirmed with the institute or register.
Which new manufacturing classes were created?
The manual also notes a change of a different kind in manufacturing: the content of classes can move without a split or merger being listed as the headline change. The passage on class 20.59 shows the pattern, where former classes for explosives, glues and essential oils were moved into the new class 20.59, while liquid biofuels were separated into class 20.51. A reader who follows only the split headline would miss the moves into the residual class. The full passage, the correspondence table, and the notes for both classes must be read together.
What does the manufacturing changelog not show?
The manufacturing changelog in the manual does not show minor changes, and it does not show the full correspondence for every class. It lists major changes, as defined in the manual, and it states that minor changes include heading changes, renumbering, recoding and partial transfers of content. A manufacturing class that is not listed in the major changes passage may still have changed in a minor way, and its note in the new version must be compared with its note in the old version before a comparison over time is made. The changelog also does not show the effect of the changes on statistics. Backcasting and double reporting plans, mentioned on the Eurostat overview page, are the tools for managing breaks in series, and the correspondence table is the starting point for those tools, not a finished converted series.
Read the Section C passage in the manual for the major manufacturing changes, check the correspondence table for the class concerned, and confirm any entry with the national statistical institute or the business register that holds the record.
