How Is Domestic Sea Freight Priced? Billing Methods and Key Factors

How is domestic shipping priced?

"How much does domestic shipping cost per ton?" is a common question when shippers inquire about rates, but the freight rate is not a fixed number. The pricing method for domestic shipping differs from international shipping, and it usually takes the form of a packaged quote denominated in RMB. The specific cost is determined by the billing unit, container type, route, and market conditions. This article introduces the billing methods and influencing factors of domestic shipping to help you budget for transportation and make accurate inquiries to logistics companies.

1. Billing Units for Domestic Sea Freight

Domestic sea freight is mainly billed in two ways:

• By weight ton (ton): applicable to heavy cargo with higher density, such as steel, building materials, mechanical equipment, etc.;
• By volume (CBM): applicable to bulky light cargo, such as home appliances, furniture, textiles, etc.

LCL (less than container load) cargo is usually billed by "the greater of weight ton and volume ton," i.e., whichever value is larger is charged; FCL (full container load) cargo is billed directly per container, with relatively fixed costs.

2. Billing Differences Between Full Container Load and Less than Container Load

Full Container Load (FCL) Transportation: When the cargo volume is sufficient to fill a container, it is priced per container (e.g., 20GP, 40GP, 40HQ), and the cost is relatively fixed, suitable for large-volume cargo.

Less than Container Load (LCL) Transportation: When the cargo volume is not enough to fill a full container, it is consolidated with other shippers' cargo in the same container, and billed by ton or by volume (whichever is greater), suitable for small- and medium-volume cargo.

3. Main Factors Affecting Freight Rates

• Route distance: The longer the route, the higher the freight rate; north-south trunk routes along the coast are usually higher than routes between adjacent port areas;
• Cargo type: Ordinary dry bulk cargo has lower freight rates; oversized or special cargo (such as chemicals and steel coils) requires special container types or qualifications, resulting in higher costs;
• Market conditions and season: During peak seasons (around holidays and end of year), space is tight and freight rates rise; during off-seasons, shipping companies may lower rates to attract cargo;
• Surcharges: In addition to the basic ocean freight, quotes may also include terminal handling charges (THC), port charges, trailer fees, etc. When inquiring, you should confirm which items are included in the quote.

4. How to Get an Accurate Quote

Domestic sea freight rates are affected by multiple variables, so a unified unit price cannot be provided. When inquiring with a logistics company, it is recommended to provide the following information to get an accurate quote: cargo name (dangerous goods and chemicals must be stated in advance), total weight, total volume, port of origin and destination port, container type preference, and estimated shipping time. The more complete the information, the closer the quote will be to the actual cost.

FAQ on Domestic Sea Freight Billing

Q: Is domestic sea freight priced by weight or by volume?

A: LCL cargo is usually charged based on the greater of weight ton and volume ton; that is, heavy cargo is billed by weight and light bulky cargo by volume. FCL cargo is charged per container. Different carriers may use different billing units, so you should confirm the charging method with the logistics company when requesting a quote.

Q: What information should be provided when requesting a quote to get a more accurate price?

A: Provide the cargo name (dangerous goods/chemicals must be declared in advance), total weight, total volume, port of loading/port of destination, container type preference, and estimated shipping time. The more complete the information, the more accurate the quote, and the less back-and-forth communication needed.
