For the purposes of heading (/headings/9406), the expression 'prefabricated buildings' means buildings which are finished in the factory or put up as elements, presented together, to be assembled on site, such as housing or worksite accommodation, offices, schools, shops, sheds, garages or similar buildings.

Such modular building units are normally designed to be assembled together to form permanent buildings. ### Additional chapter notes 1.
