Freight refers to any shipments of goods, items or commodities weighing more than 150 lbs that are transported via air, surface or ocean transport.In order to standardize the pricing classifications of shipping industry, freight classes are used, establishing similar parameters between multiple stakeholders i.e., brokers, warehouses, carriers etc.

Following table correlates the type of freight, its density and freight class code. It can be used to calculate freight class based on type of material being shipped and their density.

Freight class code |
Type of freight |
Weight per ft^{3} |

50 | Durable freight that fits on a standard 4′ × 4′ pallet | 50+ lbs. |

55 | Bricks, cement, hardwood flooring, construction materials | 35–50 lbs. |

60 | Car accessories, car parts | 30–35 lbs. |

65 | Car accessories and parts, boxed books, bottled drinks | 22.5–30 lbs. |

70 | Car accessories and parts, auto engines, food items | 15–22.5 lbs. |

77.5 | Tires, bathroom fixtures | 13.5–15 lbs. |

Following steps can be used to manually calculate the Freight Density of the shipment. If shipment consists of multiple packages, following steps need to be repeated for each piece.

Measure the length, width and height of the freight pallet using a simple measuring tape.

Measure weight of the shipment using a weighing balance.

Multiply the 3 above mentioned dimensions of the freight pallet to find the volume of the shipment by using the following formula:

Formula

$$Volume = Length \times Width \times Height$$

Compute the density of the shipment by dividing the already measured weight of the pallet with the calculated volume as per the following formula:

Formula

$$Density = \dfrac{Weight}{Volume}$$

This interactive shipping class calculator accommodates a wide range of measurement units i.e. inches, feet, centimeter, meter, yard, mile, lbs, kg, stone etc.

**Inputs:**

**Dimensions**: Insert length, width & height of the pallet in the input fields.**Number of Pallets**: Enter the quantity of pallets in the “Pallet Quantity” input field and hit “Calculate” button.**Freight Rate**(Optional): If you know the freight rate charged by your shipper, enter it into this field.

**Outputs:**

Following outputs are generated instantly and the process could be repeated by hitting “Recalculate”:

- Freight Class: This class freight calculator calculates the class of a shipment based on the density of the consignment.
- Shipping Cost: It also estimates the cost of the shipment if the user inputs the freight rate in the relevant field.

Following are the factors which play a pivotal role in the freight classification:

- Density:
- Stow-Ability:
- Handling:
- Liability:

The purpose of freight class is to standardize the classification of commodities transported by LTL shipping. This classification system makes sure that customers receive unbiased price when shipping freight because carriers use this classification for pricing of freight rates and formulating the cost to ship your freight.

Freight class and shipping costs are directly related i.e., higher the freight class, higher will be the shipping charges. In terms of shipping costs, freight class 500 is the most expensive freight class.

Books fall under the Freight class 65 whereas food items are covered in Freight Class 70.
