International logistics freight calculation methods can be quite complex, often determined by multiple factors. Here are some common calculation methods and considerations:

By weight

Actual Weight: When the actual weight of the goods is heavier, the shipping cost is usually calculated based on the actual gross weight, with the unit generally being kilograms (kg). For instance, for items with high density, such as metal products, machinery, and equipment, the shipping cost is determined by the weight obtained from actual weighing.

Volume Weight: For goods that are large in volume but light in weight, such as plush toys and foam products, logistics providers typically calculate shipping costs based on volume weight. The formula for calculating volume weight is generally: Volume Weight (kg) = Length (cm) × Width (cm) × Height (cm) ÷ 5000 (or 6000, etc., depending on the logistics provider's standards). This is because such goods take up more transportation space, so they are converted to an equivalent weight based on volume for shipping cost calculation.

In actual calculations, freight forwarders compare the actual weight with the volumetric weight, and use the higher of the two as the billing weight for calculating shipping costs.

As the distance calculates

Transport distance is a key factor affecting freight costs. Generally, the greater the distance, the higher the freight cost. Different logistics providers have their own pricing standards for various transportation routes, such as the varying cost tiers for shipping from China to different regions in the U.S., depending on the distance.

By commodity type

Freight rates vary depending on the type of goods. Special items, such as flammable and explosive materials, fragile goods, valuable items, and perishable foods, incur higher costs due to the need for specialized packaging, handling, or transportation conditions. For instance, shipping flammable and explosive chemical raw materials requires dedicated hazardous materials transport vehicles and qualifications, which significantly increases the freight cost compared to regular goods.

By mode of transport

Shipping: Freight is typically calculated based on the type and quantity of containers, with common sizes including 20-foot containers and 40-foot containers. The billing methods for Full Container Load (FCL) and Less than Container Load (LCL) shipments also differ; FCL is charged per container, while LCL is based on the volume or weight proportion of the goods within the container. Additionally, there may be additional charges for shipping, such as port handling fees, fuel surcharges, and peak season surcharges.

Air Freight: Mainly calculated based on the weight or volumetric weight of the goods, with adjustments made according to various factors such as routes, flights, and the urgency of the cargo. Air freight rates are relatively high, but offer fast delivery, making it suitable for time-sensitive shipments.

In international land transportation, such as by rail or road, freight charges are typically calculated based on the weight, volume, and distance of the shipment. For large-scale cargo transport, special transportation equipment and handling fees may also be involved.

Other Charges

Customs brokerage fee: This refers to the charges incurred when declaring goods for import or export, typically based on the value of the goods or the complexity of the declaration.

Customs Clearance Fees: Include the costs for customs inspection, taxation, and a series of other clearance procedures, with varying standards across different countries and regions.

Fuel Surcharge: Due to fluctuations in fuel prices, logistics providers may charge a fuel surcharge to balance costs, which is typically adjusted in line with the rise or fall of fuel prices.

Insurance Fees: While not mandatory, many shippers opt for cargo insurance to ensure the safety of their goods during transit. The insurance fee is calculated based on the value of the goods and the insurance terms.

The calculation of international logistics shipping costs is a comprehensive process considering various factors. When selecting logistics services, shippers need to thoroughly understand the calculation methods and standards of various fees with the logistics provider to accurately calculate transportation costs.
