How Do We Calculate Warehouse Member Dues?

IARW Warehouse Members dues are based on company’s gross refrigerated space. Dues are billed on a sliding scale. Regardless of your company’s space, there are minimum dues for annual membership in IARW. Minimum dues differ by country or region. Members outside the United States receive regional discounts. Calculate Your Dues

Definition of Gross Refrigerated Space


Gross refrigerated space, on which dues are based, represents the total cubic refrigerated space, including freezers, coolers, and docks, from wall to wall, ceiling to floor, with no deduction for aisles, columns, coils, etc. This includes all space owned or operated by a member or an affiliate of a member. Not included are buildings used in their entirety for storage of product owned by the member or buildings leased in their entirety with no operating personnel supplied by the member company. However, any facility covered by the IARW Insurance Program must be included for dues purposes.
