What Landed Cost Includes
Landed cost is the cost of getting sellable baking supplies from the supplier invoice to arrival in Australia. It starts with the product cost, then adds international freight, cargo insurance, customs duty, broker or clearance charges, port and import fees, and any applicable tax. If an import tax is recoverable by your business, record it separately rather than treating it as a permanent product cost; a non-recoverable amount belongs in landed cost.
This is different from the supplier invoice total and from the cost of selling the item. Landed cost excludes warehouse storage, handling after arrival, Shopify or payment fees, advertising, staff, fulfilment, returns, selling expenses and your margin. Those belong in later profitability calculations.
Tax treatment needs care. Business.gov.au states that GST is 10% on most goods, services and other items sold or consumed in Australia, and that a business must register when its GST turnover reaches $75,000 or more. For low-value physical goods sold to Australian consumers, GST generally applies at A$1,000 or less, based on customs value excluding transport and insurance, according to business.gov.au. Apply the rule relevant to the transaction rather than adding GST automatically (Source: business.gov.au (Australian Government)).
Build the Cost Stack in Separate Lines
Keep the cost stack as separate lines before dividing anything by units. This makes it clear whether a change came from the supplier invoice, import charges, transport or tax. Record every line in the same currency and retain the shipment total alongside the per-unit result.
Use two outputs: landed cost before GST for product-margin analysis, and total cash paid including GST for cash planning. GST is 10% on most goods and services in Australia, according to business.gov.au (Australian Government). Its treatment should remain visible rather than being silently added to product cost (Source: business.gov.au (Australian Government)).
- Product cost: supplier invoice total, converted to your trading currency.
- Duty: shipment duty amount, kept separate from the product value.
- Freight and other arrival costs: international freight, insurance, handling, brokerage and local delivery where applicable.
- Subtotal before GST: product cost + duty + freight and other arrival costs.
- GST: record the applicable GST amount as its own line.
- Landed cost per unit: subtotal before GST ÷ sellable units received. Total cash cost per unit: (subtotal before GST + GST) ÷ sellable units.
| Measure | Use it when |
|---|---|
| Landed cost before GST | Setting margins and comparing supplier or freight options |
| Total cash cost including GST | Planning the payment required for the shipment |
Worked example with sample numbers
This example is illustrative. It uses sample numbers for a baking supplies store selling in Australia. They are made up to show the method, they are not a benchmark, and your own figures will differ.
Formula: Landed unit cost = (supplier cost + freight + duty + fees) / units.
| Line | Shipment | Per unit |
|---|---|---|
| Supplier cost | A$21303.06 | A$25.98 |
| Freight | A$2167.08 | A$2.64 |
| Duty | A$761.49 | A$0.93 |
| Broker and handling | A$142.50 | A$0.17 |
| Landed cost | A$24374.13 | A$29.72 |

Duty and Classification Basics
Customs duty is determined by tariff classification, not by a store’s internal product category or a supplier’s generic invoice label. The classification can affect whether duty applies, the applicable rate, and whether a concession or other treatment is available. Do not assume a rate for “baking supplies” as a group: a piping bag, aluminium tray, decorating tool and food-contact container may require different classifications.
Before approving the landed-cost model, verify the customs description against the product’s material, construction, function, packaging and intended use. Check the country of manufacture, not only the dispatch country, and retain any origin statement or supporting documentation required for a preferential claim. Ask the broker to confirm the tariff classification and origin treatment for the exact SKU. Record that decision beside the SKU so a later supplier or packaging change triggers a review. The Australian seller guides provide context, but the classification decision should come from the customs documentation for your shipment.
Allocating Freight to Units
Allocate freight according to what actually consumes the carrier’s capacity. Unit allocation is simple: if a shipment contains 1,000 identical cupcake boxes, A$1,000 of freight assigns A$1.00 per box. It becomes misleading when one stock-keeping unit is a light whisk and another is a heavy stand mixer.
For mixed shipments, use the carrier’s chargeable measure where available, then apply the same basis consistently to each product line. A shipment can be allocated in stages: assign shared freight by weight or volume, then divide each line’s share by its units. Keep the allocation basis visible in your product cost model so margin changes are explainable.
- Units: suitable for similar-sized, similar-weight products packed in comparable quantities.
- Weight: appropriate when freight is priced by kilograms, such as metal tools, bulk ingredients or dense packaging.
- Volume: appropriate when cartons fill vehicle or container space before reaching a weight limit, such as cake boxes, moulds or bulky displays.
- Shipment value: useful when freight or insurance is calculated as a percentage of declared value. It is not a proxy for physical capacity: a high-value, lightweight item should not absorb freight merely because its invoice value is high.
| Basis | Use it when | Main risk |
|---|---|---|
| Units | Products are materially alike | Overcharges bulky or heavy lines |
| Weight | The carrier charges by weight | Ignores unused carton space |
| Volume | Space is the constraint | Needs reliable packed dimensions |
| Shipment value | The charge follows declared value | Can distort freight for high-value goods |
Rules to Confirm Before Importing to Australia
Before booking freight, check the shipment against the Australian Border Force import requirements: product description, tariff classification, customs value, origin documents and any permit or prohibition. Confirm conditions in the Department of Agriculture, Fisheries and Forestry’s BICON system, especially for timber, plant-based materials, natural fibres or goods carrying soil, seeds or other biosecurity risk. Packaging may also need treatment or inspection.
For tax, the Australian Government says GST is 10% on most goods and services. GST-registered businesses collect one-eleventh of the sale price, and registration is required at $75,000 GST turnover. Separately, GST applies to most retail sales of low-value physical goods imported by Australian consumers, goods with a customs value of A$1,000 or less, excluding transport and insurance from that threshold (business.gov.au). Confirm the treatment of your import with the Australian Taxation Office (Source: business.gov.au (Australian Government)).
If a product will touch food, check FSANZ Food Standards Code Standard 1.4.3 and supplier evidence for food-contact suitability. Check ACCC rules for product claims, warnings and country-of-origin labelling where applicable. For packaging, review any mandatory product-specific requirements and biosecurity conditions rather than assuming supplier packaging is acceptable.
How to Read the Worked Landed-Cost Example
Read the worked example from the source document to the final per-unit figure. Trace the product amount to the supplier’s commercial invoice: confirm the description, quantity, unit price, currency and line extension. Trace freight, insurance, brokerage and border charges to the relevant carrier, customs or agent documents. Each input should have a document, not an assumption.
Keep shipment totals separate from unit amounts. A supplier invoice may show a per-unit price, while the freight invoice shows one charge for the entire consignment. First reconcile the shipment-level stack; only then divide the applicable total by the units received and included in the allocation. Test the arithmetic in both directions: quantity × invoice unit price should equal the invoice line total, and allocated freight across all products should equal the freight document’s charge. Also check that the denominator is sellable units, the currency is consistent, and tax has not been included twice. If the result differs from the supplier or freight paperwork, find the missing quantity, charge, conversion or allocation before using it for pricing.
A useful landed-cost model leaves product cost, freight, duty and tax auditable on separate lines before producing the unit figure. Recheck classification and import requirements for each product and shipment, then use the same allocation method consistently when comparing supplier or freight options.
