Size and weight are the most crucial factors when getting a freight quote. Be sure to include the weight and dimensions of the packaging you are using to ship your item. If you fail to include those the carrier hired to handle your freight will issue you a billing adjustment for the adjusted weight and size.
Freight class is a way of classifying freight shipments. Freight classes are set up by National Motor Freight Classification. They determine an items freight class based on stowability, size and weight, and commodity type. Be sure you select the right freight class when shipping to avoid complications later on.
Lanes can also factor into shipping cost. Your pickup and drop off location determine what lane your shipment will travel, and each lane has its own set of fuel charges that go with it.
By having all of these factors in mind, you can plan smarter and ship easier.
