About this level

Practical summary

Class 2811 sits in the PSIC 2019 hierarchy under C Manufacturing > 28 Manufacture of Machinery and Equipment, n.e.c. > 281 Manufacture of general purpose machinery. This class usually fans out into more specific subclasses such as Manufacture of Internal Combustion Engines (gas and Diesel), Manufacture of Engines and Turbines for Marine Propulsion, and Manufacture of Parts of Engines and Turbines, except for Aircraft, Vehicle and Cycle Engines. It is the level people use when they already know the activity family but still need the exact five-digit match.
