Tare weight is the weight of the packaging or container in which products are packed. In commercial and industrial settings, tare weight is critically subtracted from the gross weight to ascertain the net weight of the goods, which represents the actual weight of the product without its container.
Calculation of Tare Weight
To determine the net weight:
Where:
- Gross Weight: Total weight of the container and its contents.
- Tare Weight: Weight of the empty container or packaging.
- Net Weight: Weight of the contents alone.
Types of Tare Weight
- Standard Tare: Predefined and universally accepted weight for a type of container.
- Controlled Tare: Specific to a consignment where the tare weight is measured and documented.
- Declared Tare: Stated by the manufacturer or packager, often found on labels.
Special Considerations and Examples
Example Calculation
Imagine you have a shipping container that weighs a total of 1,000 kilograms:
- Gross Weight: 1,000 kg
- Tare Weight of the container: 200 kg
The Net Weight of the goods would be:
