Depending on the specific needs of the customer, moving companies have some flexibility in determining their charges. Most moving companies determine charges by the actual costs and market conditions, however tariffs are still determined by an industry organization called the Household Goods Carriers Bureau. With a local move, cost will more than likely be based on an hourly rate and the amount of labor time, rather than by the distance of your move. For an interstate move, however, cost is usually determined by the weight of the shipment and the distance to your final destination. A local moving company can give you more information on exactly how moving charges are determined.
