Class 2431 - Casting of iron and steel

Class 2431 sits in the PSIC 2019 hierarchy under C Manufacturing > 24 MANUFACTURE OF BASIC METALS 'This division includes the activities of smelting and/or refining ferrous and non- ferrous metals from ore, pig or scrap, using electrometallurgic and other process metallurgic techniques. This division also includes the manufacture of metal alloys and super-alloys by introducing other chemical elements to pure metals. The output of smelting and refining, usually in ingot form, is used in rolling, drawing and extruding operations to make products, such as plate, sheet, strip, bars, rods, wire, tubes, pipes and hollow profiles, and in molten form to make castings and other basic metal products. > 243 Casting of metals. This class usually fans out into more specific subclasses such as Casting/foundry of Iron and Casting/foundry of Steel. It is the level people use when they already know the activity family but still need the exact five-digit match.

This class is used when a business can already narrow the activity family and only needs to compare the final subclasses such as Casting/foundry of Iron and Casting/foundry of Steel. It is the level most often checked before a five-digit decision is finalized.

Use this class to choose between its final subclasses such as Casting/foundry of Iron and Casting/foundry of Steel. If two options look close, compare the exact activity, the outputs and the way the business actually earns revenue.
