A small appliance is defined by EPA as

Under EPA rules, a small appliance is defined by how it is built and charged: it must be manufactured, charged, and hermetically sealed in the factory, and it must contain 5 pounds of refrigerant or less. This precise combination distinguishes small appliances from larger systems that may be charged in the field or contain more refrigerant. That’s why the description stating it is an appliance manufactured, charged, and hermetically sealed in a factory with 5 pounds or less of refrigerant best fits the definition. The other statements miss key points: military use is irrelevant to the classification, any refrigerant charge ignores the 5-pound limit, and not being hermetically sealed contradicts the sealed, factory-made requirement. For context, a window air conditioner with about 4 pounds of refrigerant would be considered a small appliance, while a large commercial chiller with tens of pounds would not.
