Can I calculate customs duties for Australia?

The customs calculator includes Australian import assumptions. Check the country-specific guidance shown in the tool and confirm applicable charges for your shipment.

How do I optimise container loading?

Use our Container Load Optimiser to calculate the best container type (20ft, 40ft, 40HC) for your cargo. Enter your cargo dimensions and quantities to see optimal loading configurations and cost comparisons.

How do I estimate transit time for my route?

Use the transit calculator for supported routes. Timing depends on origin, destination, transport mode and provider schedules; confirm the expected milestones and any excluded delays with the provider.

How do I calculate demurrage and detention charges?

Our Demurrage & Detention Calculator helps you estimate daily charges when containers are held beyond free time. Demurrage applies at the port/terminal, detention applies when you have the container. Rates vary by shipping line and container type.

Can I calculate carbon emissions for my shipments?

Yes, our Carbon Footprint Calculator estimates CO2 emissions based on shipping method, distance, and cargo weight. Sea freight produces 10-50g CO2/ton-km while air freight produces 500-1500g CO2/ton-km. Track your environmental impact for ESG reporting.

What insurance premium should I expect?

Cargo insurance typically costs 0.2-0.5% of the cargo value (CIF + 10%). Use our Insurance Premium Calculator to estimate costs based on your cargo type, value, and shipping route. Higher-risk goods may have premium rates.

Container loading: inputs, method and limitations

Use this calculator to organise a planning scenario and understand how its inputs affect the result. It is most useful when you keep a record of the units, dates and service assumptions. For container loading, the information you enter should describe the actual requirement rather than an idealised example.

Prepare the inputs

Collect container type, packed cargo dimensions, weights, quantities and handling constraints. Check that the measurements and quantities use consistent units. If a value is unknown, label it as an assumption and revisit the result when confirmed information becomes available.

Interpret the result

Review both usable volume and payload. Check whether the goods can pass through the doors and be arranged in a practical loading sequence. Keep a separate record for cargo that cannot be stacked.

Check before relying on the estimate

Space lost to packaging, securing, irregular shapes and access can reduce practical utilisation. Confirm equipment specifications and a workable loading plan before relying on an estimate to select a container.

Questions before you proceed

Can I use the result as a confirmed offer?

No. A calculator explains the scenario entered. Ask the responsible provider to confirm the applicable service, method, terms and final commercial offer.

How should I compare two scenarios?

Change one assumption at a time, keep the units and calculation boundaries consistent, and record why the input changed. Confirm the preferred scenario against the actual goods and service requirements.
