How to Calculate Landed Cost When Importing from China to Australia

The landed cost of a China order is the total cost of getting usable stock to the point where your business can sell or deploy it. It is not the supplier's unit price plus a rough freight percentage.

For an Australian importer, a workable model should produce three different answers:

1. Customs assessment inputs: customs value, any duty, and the value used to calculate import GST.
2. Landed cash requirement: how much cash must leave the business to get the shipment to the nominated warehouse.
3. Economic landed cost per saleable unit: the cost used for margin decisions after considering GST treatment and units that will not be saleable.

Mix those answers into one number and the spreadsheet becomes difficult to audit. You may count freight twice, apply duty to the wrong base, treat potentially creditable GST as permanent cost, or spread fixed charges across stock that cannot be sold.

This guide shows the method with an invented 1,000-unit sea-freight example. It is not a customs ruling or freight quote. Classification, origin, valuation, anti-dumping exposure, biosecurity requirements and GST credit eligibility must be checked for the actual product and importer.

Start by fixing the calculation boundary

Write the endpoint at the top of the sheet. Landed at Port Botany is not the same cost boundary as available in our Western Sydney warehouse after inspection.

A useful boundary for an SME is:

Goods available at the nominated Australian warehouse, including order preparation, international transport, border charges, clearance and local delivery, but excluding costs triggered only when an individual unit sells.

The Incoterms® rule and named place in the supplier quote determine where one party's cost responsibility stops and the other's begins. A price quoted FOB Yantian, Incoterms® 2020 includes a different scope from EXW supplier factory address, Incoterms® 2020.

Do not add a standard origin-freight line simply because the template contains one. If that cost is already inside the supplier's price, adding it again double counts it. Record the source document and status beside every input: quoted, confirmed, estimated, conditional or excluded.

If supplier offers are not on the same basis, first use the Chinese supplier quotation comparison method. A landed-cost model cannot repair an undefined product or shipment scope.

Build the input sheet in cost buckets

The model should be detailed enough to reconcile against invoices after arrival. These buckets separate costs that have different evidence and allocation rules.

Tooling, samples and compliance testing need an explicit policy. If they benefit only this order, include them. If a mould supports many reorders, show the cash outlay but allocate its economic cost over a documented expected volume. Do not hide the choice in a formula.

Selling expenses are outside landed cost. Marketplace commission, payment processing, pick-and-pack, outbound delivery, customer returns and advertising belong in contribution-margin analysis. EVG-017 uses those costs to calculate the order's break-even quantity.

Calculate customs value before duty

The Australian Border Force says customs value is usually based on the transaction value—the price paid or payable—subject to adjustments. Australia generally values goods at the place-of-export level. Overseas freight and insurance from that place to Australia are generally excluded from customs value.

That means the common internet shorthand duty on CIF is not a safe Australian rule. The customs value may include costs such as packing, production assists, certain commissions or royalties, and foreign inland freight incurred before the goods leave the place of export. A CIF or DDP invoice may require supported deductions or adjustments rather than being copied into the customs-value cell.

Use this calculation structure:

Estimated duty = customs value in AUD × applicable duty rate

The applicable rate depends on tariff classification and any concession or preferential claim. ChAFTA does not make every Chinese-origin shipment automatically duty-free: the goods must meet the relevant origin rule and evidence requirements. Anti-dumping or countervailing measures can also change the result.

For a material commitment, ask a licensed customs broker to confirm classification, valuation, origin and trade-remedy exposure. The Australian import taxes overview explains the surrounding tax concepts.

Calculate import GST on the right base

For a taxable importation, ABF says GST is 10% of the value of the taxable importation. In the ordinary case used here, that value consists of:

• customs value;
• customs duty;
• international transport and insurance to the place of consignment in Australia; and
• Wine Equalisation Tax, if applicable.

The simplified model is:

Import GST = 10% × (customs value + duty + international transport and insurance + applicable WET)

Destination cartage beyond the place of consignment, broker fees and warehouse receival are commercial landed costs, but they are not automatically added to this particular ABF formula. Keep them in the landed-cash layer.

Import GST can still be a major cash requirement. However, the ATO says a GST-registered entity importing goods for a creditable business purpose may be entitled to an input tax credit. If that applies, the GST may be recoverable through the BAS rather than a permanent economic cost.

Model both treatments:

• Cash view: include import GST when it must be paid or funded.
• Economic view: exclude only the amount your accountant confirms is creditable; retain non-creditable GST as cost.

Do not remove GST from the cash-flow forecast merely because it may later be claimed.

Add current declaration charges and shipment-specific costs

At the 2026-08-10 retrieval date, ABF lists an electronic import-processing charge of $50 for a consignment over $1,000 and under $10,000, and $152 for a consignment valued at $10,000 or more. It also lists full-import-declaration biosecurity charges from 1 July 2026 of $48 for air and $71 for sea.

Those scheduled charges are only part of clearance cost. Broker service fees, port or airline charges, deconsolidation, inspections, treatments, storage and local cartage depend on the shipment. Obtain itemised quotes instead of turning one previous invoice into a universal allowance.

Reddit discussions repeatedly ask how a product-plus-freight estimate became a much larger invoice after brokerage, documentation, terminal or storage charges. These reports are anecdotal and often concern other jurisdictions. The useful editorial signal is the question: which party will invoice each remaining step, and is it confirmed before the purchase order?

For every uncertain line, record:

• owner of the quote;
• quoted scope and exclusions;
• currency and conversion assumption;
• quote validity date;
• low, base and high amount;
• trigger that would create the charge;
• date and person responsible for refreshing it.

Worked example: 1,000 units to an Australian warehouse

Assume an Australian business is modelling 1,000 units moving by sea. All figures below are invented Australian-dollar inputs. The 5% duty rate is a demonstration assumption, not a statement about the product.

The landed cash requirement is:

$12,000 + $2,400 + $600 + $1,500 + $152 + $71 + $250 + $850 + $550 + $350 + $180 + $800 = $19,703

If all 1,000 units are saleable, the cash landed cost is $19.70 per unit after rounding.

If the full $1,500 import GST is creditable, the illustrative economic cost is $18,203, or $18.20 per ordered unit. If the importer cannot claim that credit, retain the GST in economic cost.

The model still needs a denominator decision. Suppose inspection history and product characteristics justify planning for 980 saleable units—not as a universal defect rate, but as this buyer's documented scenario. Economic landed cost becomes:

$18,203 ÷ 980 = $18.57 per saleable unit

The spreadsheet should show both $18.20 per ordered unit and $18.57 per modelled saleable unit. The difference is not a customs charge; it is a commercial yield assumption that must be monitored against actual receipt and quality data.

Replace a magic contingency with scenarios

A flat add 10% cell is easy but hard to defend. It can overstate known costs while still missing the risk that matters.

Create low, base and high cases for uncertain lines:

• freight quote expires before cargo readiness;
• exchange rate moves between quotation, deposit and balance payment;
• customs classification or origin evidence does not support the assumed rate;
• biosecurity inspection or treatment is directed;
• storage arises because documents or delivery slots are late;
• saleable quantity is below the order quantity;
• launch testing or corrective work is required.

Give each scenario a basis and owner. The output should show which variable changes cost per unit enough to breach the target margin. That is more useful than pretending every risk can be represented by one arbitrary percentage.

Foreign-exchange sensitivity belongs in the commercial model even though ABF uses its own exchange rate on the day of export for customs purposes. Your bank's rate, spread and transfer fee determine the actual cash paid to the supplier. Keep those two exchange-rate purposes in separate cells.

Common landed-cost model failures

Counting the same freight twice

The supplier price includes an origin or international charge, but the template adds it again. Tie each input to the Incoterms® boundary and invoice.

Treating customs value as CIF

ABF generally uses place-of-export valuation and separates overseas freight/insurance for the taxable-importation calculation. Do not copy a third-party formula without checking Australian rules.

Assuming China origin means zero duty

Classification, origin rules, supporting evidence, concessions and trade remedies still matter. Use a conditional cell until verified.

Omitting fixed destination charges from a small order

Broker, declaration, handling and local-delivery charges can be material when spread across a low quantity. Ask for itemisation and allocate consistently.

Treating recoverable GST as either irrelevant or permanent

GST can create a real funding requirement even if later creditable. Show the cash and economic views separately.

Dividing by the wrong units

Ordered, received and saleable units may differ. Show the reconciliation and do not invent a standard loss factor.

Stopping at the warehouse

Landed cost is not full unit economics. Selling commissions, fulfilment, returns, outbound freight and acquisition cost still have to be covered.

Questions to answer before approving the order

• What exact location does the landed boundary use?
• Which Incoterms® rule and named place govern the supplier price?
• Has the customs value and tariff classification been reviewed for this product?
• Is the assumed duty rate supported by origin evidence and a trade-remedy check?
• Which freight, destination and clearance amounts are confirmed, provisional or excluded?
• What is the low/base/high freight and exchange-rate case?
• Can import GST be claimed, and when will the cash effect reverse?
• How many units are expected to be received and saleable?
• Which one-time costs should be expensed to this order or amortised over later orders?
• What invoice or source will replace each estimate after shipment?

Use landed cost as an input, not the final decision

A precise landed cost does not prove an order is viable. It proves the business has a controlled cost input.

Fix the boundary. Reconcile supplier and logistics scope. Apply Australian customs and GST rules on their proper bases. Show cash and economic treatment separately. Allocate the result to a defensible unit denominator, then stress-test the assumptions that could move the decision.

The next question is how many units must sell before those costs are covered and the initial cash commitment is recovered. The import order break-even calculator applies the landed-cost inputs without mixing them into a false single margin.
