The tariff classification of heat recovery ventilators from CanadaDear Mr. Steere:In your letter dated January 28, 1993 you requested a tariff classification ruling.You enclosed data sheets on three heat recovery ventilators: VA3A, VB5A and VC5A. Heat revoery ventilators are basically heat exchangers that transfer heat from warm, stale and humid air that is about to be expelled from a home to fresh, cold air being drawn from the outside to replace it. The heat recovery core is made of polypropylene. Within the core are two motor-driven fans that control the two air flows. A dehumidistat control allows the user to select the relative humidity level at which the unit would change speed for dehumidification in the winter months. A condensate tray with drain is positioned just below the heat recovery core. A filter installed on the incoming outdoor air stream removes large airborne particles from the intake air stream.The applicable subheading for the VA3A, VB5A and VC5A Heat Recovery
