NIC 812901 - Cleaning of trains, buses, aeroplanes etc.

Use this code only when cleaning of trains, buses, aeroplanes etc. is the closest description of the actual business activity. If revenue comes from trading, processing, support services or a different output, compare the relevant sibling or downstream Division.

Avoid this code if the business merely supplies, transports, sells or supports this activity without performing the core business activity. In that case, choose the trade, transport, service or manufacturing code that describes what the business actually does.

Check the parent hierarchy, compare 812902 Cleaning of industrial machinery, 812999 Other cleaning activities n.e.c. such as swimming pool cleaning and maintenance, exterior cleaning of buildings of all types, specialised cleaning for buildings (windows, chimneys, exhausts, etc.), disinfecting activities, street sweeping and snow and ice removal, steam cleaning, sand blasting and similar activities for building exteriors, and confirm that the official title matches the main revenue activity. For regulated or filing-critical decisions, verify the source row in the MoSPI dataset.

A wrong code can cause mismatched business descriptions, follow-up questions or later compliance cleanup. It is better to compare nearby codes before filing than to correct a weak classification later.
