Tare is the weight of a vehicle or container when it is empty. This weight is used in calculations of net weight for tasks which range from properly charging customers for consumer goods to taxing laden trucks as they cross borders. To calculate the net weight of a load, the container is weighed to establish the tare weight and then weighed again for the gross weight, and the tare is subtracted from the gross to find out how heavy the load is.
Insert 52.232-9002, Tare Included or Excluded, in solicitations/contracts that discuss tare. For instance, IFBs, RFPs, and RFQs for fiber rope, cordage or twine when purchase is on a per pound basis and weight of tare is included would select the first paragraph while those that exclude tare would select the second paragraph.
52.232-9001, Invoice Confirmation - Commercial Manuals, may be used when the contractor will be required to distribute commercial manuals. DO NOT use if the requirement for commercial manuals is waived in the Purchase Order.
