Weightmaster Certificate

A weighmaster certificate also called a weight slip or weight ticket certifies the weight of a product like coal or rock sold in bulk in the trucking industry. It can also be an invoice but does not have to be. It's quite common in the coal industry where a dealer will have a certificate without the price marked and be providing their own separate invoice. This ticket must be given to the final customer.

When a truck first enters a coal yard or quarry they will first go on the scale to get the light or tare weight. Once the truck is loaded it will again be pulled on the scale to get the total or gross weight. The difference between these two weights is the net weight or the total weight of the product on the truck.

  • Gross Weight - Tare Weight = Net Weight

Within the coal delivery business since a truck may have many compartments the ticket for each compartment will have different tare and gross weights. For example if a truck with 2 compartments pulls on the scale empty with a tare weight of 15,000 lbs. and then proceeds to put 2 tons of product in one compartment the gross weight for that ticket will be 19,000 lbs. This gross weight will also act as the tare weight for the next ticket and second compartment.

Within the state of Pennsylvania by law all items sold in bulk via a truck need a certificate from a certified scale. This certificate is either mechanically printed or can be hand written. There are four copies. A white copy or the original that is for the Customer purchasing the coal. A blue Copy for the dealer, our example image is the blue dealer copy. Note the "Void-Customer Do not Accept" in the upper left. A pink copy that must be retained at the scale location for X amount of years and finally a yellow copy used for the office records of the original seller.

A certificate should contain the following items:

  • Full Address of the scale
  • Date of Weighing
  • Time of Weighing
  • License plate number on the truck/trailer
  • Size of coal
  • Dealers Name and Address
  • Name and Address of the Customer (does not have to be exact street address)
  • Weigtmasters signature and lic. number
  • Tare Weight
  • Net Weight
  • Gross Weight
