Refrigerating or Freezing Equipment, N.E.S.; Heat Pumps

This heading captures refrigerating and freezing equipment that does not fit the more specific SITC categories for household refrigerators, commercial display furniture, or air conditioners. Examples include industrial process chillers, blast freezers for food manufacturing, and heat pumps used for space heating or industrial heat recovery — provided they are not classifiable under a more specific heading.

Heat pumps that primarily function as refrigerating or freezing equipment with a secondary heating output generally classify here. However, units designed primarily as air conditioners with a heat-pump mode may fall under the air conditioning machines heading instead. The principal function and design intent, supported by manufacturer technical specifications, should guide the classification decision.
