What is Tare Weight? Understanding it Correctly to Avoid Confusion
Tare Weight is a critical term in the container transport industry, directly impacting transportation costs and cargo management. Understanding Tare Weight enables businesses to optimize logistics processes, avoid errors in declarations, and accurately calculate load weights. Join Tân Thanh Container as we explore what Tare Weight is, its importance, precise calculation methods, and a comparison of Tare Weight for common container types in this detailed article!
What Is Tare Weight?
Tare Weight refers to the weight of an empty container, excluding any cargo. This weight includes all components of the container, such as the floor, walls, ceiling, doors, chassis, and other fixed parts. Tare Weight is clearly indicated on the door of each container and plays a vital role in determining the actual weight of the cargo inside.
What Is Gross Tare Weight?
The term Gross Tare Weight combines two concepts:
- Gross Weight: The total weight (container + cargo).
- Tare Weight: The weight of the empty container.
The key formula to remember is: Gross Weight = Tare Weight + Net Weight (cargo weight).
Example: If a container’s Tare Weight is 3 tons and the Net Weight of the cargo is 25 tons, then Gross Weight = 28 tons.
Significance of Tare Weight in Container Transport
Tare Weight is more than just a number on a container; it holds significant importance in transport operations:
- Calculating Cargo Weight (Net Weight): Tare Weight is essential for determining Net Weight. By subtracting Tare Weight from Gross Weight, businesses can accurately calculate the weight of the cargo inside the container.
- Ensuring Transport Safety: Knowing Tare Weight and Gross Weight prevents overloading, ensuring safety during transport, loading/unloading, and storage. Overloading can pose risks to vehicles, roads, ports, and personnel.
- Complying with Customs Regulations: Tare Weight is a critical parameter in customs procedures. Accurate declaration of Tare Weight facilitates smooth customs clearance and avoids legal issues.
Tare Weight of 20ft and 40ft Containers
According to ISO 668:1995 standards, technical specifications for container dimensions and weights used in maritime transport are clearly defined. Containers are categorized by size and assigned codes for easy identification. Common container types include:
- 20ft Container:
- Tare Weight: Approximately 2.2 tons.
- Maximum Allowable Load: 24,000 kg.
- 40ft Container:
- Tare Weight: Approximately 4 tons.
- Maximum Allowable Load: 30,480 kg.
How to Calculate Tare Weight Accurately and Easily
Step 1: Identify Technical Specifications
- Check the container code (e.g., COSU 1234567).
- Review the specifications printed on the container: MAX GROSS, TARE, NET.
Step 2: Apply the Formula
- Net Weight (cargo) = Gross Weight - Tare Weight.
Real-World Example:
- A 40HC container has a Tare Weight of 3.9 tons.
- After loading, the total weight (Gross Weight) is 28 tons.
- Net Weight = 28 - 3.9 = 24.1 tons.
Step 3: Cross-Check with Contract
- Compare the calculated Net Weight with the cargo weight listed on the invoice to identify any discrepancies.
