A quick guide to ACC levy classifications
4 Nov 2021
A quick guide to classifying prefabricated building manufacturers and installers:
Based on the current levy classification definitions, if a business provides the service of manufacturing and installing/erecting a whole kitset building or dwelling; it must be classified under the relevant construction classification, e.g. – 41110 House construction, 41130 Non-
residential building construction.
If the business is only engaged in the manufacture of prefabricated buildings/dwellings in a factory setting, then the relevant manufacturing classification applies.
If the business is manufacturing and installing only the individual components of a building – again, the relevant manufacturing classification would be applicable.
Common levy classifications:
29190 Prefabricated wooden building manufacturing - includes manufacturing of wooden prefab houses / kitset dwellings, garages, wooden sheds. Excludes the manufacture of prefabricated buildings in conjunction with onsite erection / assembly of buildings.
29110 Prefabricated metal building manufacturing - includes manufacture of metal sheds, carports, bus shelters, kitset homes. Excludes the manufacture of prefabricated buildings in conjunction with onsite erection / assembly of buildings.

window frames, doors. Excludes fabrication and installation of joinery on a building site (which would fall under the classification: 42420 Carpentry services).
27490 Structural metal product manufacturing (not elsewhere classified) - includes manufacturing metal (except aluminium) balconies, balustrades, curtain walls, doors or door frames, fascias, prefabricated fire escapes, partitions, railings.
