FIBC cost per tonne: use the actual planned fill quantity

The purchasing question

A bulk bag price does not directly express packaging cost per tonne shipped. The allocated cost depends on the actual product quantity packed in each bag and whether a liner is included. A nominal capacity should not be used as an assumed payload without checking the approved application.

Calculation method

Cost per metric tonne packed = complete bag-and-liner cost ÷ entered fill mass in kilograms × 1,000. This is an allocation of price over user-entered mass. It does not determine a safe working load, lifting arrangement or suitability for a particular product.

Worked example

A bag at €8 plus a €1 liner costs €9 per pack. At an entered fill of 1,000 kg, allocation is €9 per tonne. At 750 kg, the same set costs €12 per tonne. Packing 15 tonnes at 750 kg per bag requires 20 bags and a €180 component subtotal.

A lower cost per tonne at a higher fill is not authorization to increase loading. Use the fill quantity already approved for the bag, product and operation. Compare transport and handling separately, and do not add a liner price if it is included in the quoted bag price.

Checks before using the result

• Use the approved planned product fill mass.
• Include the liner only if separately purchased.
• Round required bag count up for a complete order.
