Importing goods into Australia involves more than paying the supplier and arranging delivery. Customs duty, Goods and Services Tax (GST) and tariff classification can all affect the amount you pay and how smoothly your shipment clears customs. Getting these details wrong may result in delays, additional charges or compliance action.
Every imported product needs to be classified under Australia’s customs tariff. International Harmonised System (HS) codes provide the starting point, but Australian tariff classifications contain additional detail. The correct classification helps establish the applicable rate of customs duty and whether particular import requirements apply.
Classification depends on the characteristics of the goods, including their materials, purpose and construction. Two products that appear similar may fall under different tariff headings. The country of origin may affect the duty treatment, including whether a preferential rate is available, but does not by itself determine the product’s tariff classification.
Importers are responsible for providing accurate information. Check the Australian Border Force Working Tariff or ask a licensed customs broker to assess the goods before the import declaration is lodged.
Customs duty and import GST are related, but they are not calculated in exactly the same way.
For goods subject to an ad valorem duty rate, customs duty is generally calculated using the customs value of the goods and the applicable tariff rate. Customs value is determined under Australian valuation rules, commonly starting with the price paid or payable and making adjustments where required. International freight and insurance are generally not included in customs value.
The rate can vary according to tariff classification, origin and any applicable concession or free trade agreement. Certain products may also attract anti-dumping or countervailing duties, so a standard tariff rate does not always tell the full story.
GST on a taxable importation is generally 10% of the value of the taxable importation (VoTI), not simply 10% of customs value. The VoTI includes customs value, applicable customs duty, international transport and insurance not already included in customs value, and Wine Equalisation Tax where applicable.
Assume a shipment has a customs value of A$10,000, an applicable customs duty rate of 5%, and A$1,000 in international freight and insurance, with no Wine Equalisation Tax or other additional duties.
Customs duty: A$10,000 × 5% = A$500
Value of taxable importation: A$10,000 + A$500 + A$1,000 = A$11,500
Import GST: A$11,500 × 10% = A$1,150
In this example, duty and GST total A$1,650, excluding import processing charges, biosecurity charges or any other applicable costs. Actual amounts depend on the goods and circumstances of importation.
Australia has free trade agreements with a range of trading partners. Eligible goods may qualify for reduced or zero customs duty, but eligibility is not automatic just because the goods were shipped from a partner country.
The goods must satisfy the relevant agreement’s rules of origin, and the importer must meet the applicable claim and evidence requirements. A licensed customs broker can help check whether preferential duty treatment applies before a declaration is submitted.
Incorrect tariff classification. Using an unsuitable tariff code can lead to the wrong duty rate being declared and may result in additional amounts payable, amendments or penalties.
Incorrect customs value. The invoice price is not always the final customs value. Missing valuation adjustments or declaring inaccurate amounts can create compliance problems.
Incomplete documents. Missing or inconsistent commercial invoices, origin information and other supporting documents can delay clearance or make a concession difficult to substantiate.
Confusing duty-free with GST-free. A zero customs duty rate does not automatically mean an importation is exempt from GST. Different legal tests apply.
Not planning for payment. Customs duty and GST are generally payable as part of the import clearance process. Eligible businesses approved for the Deferred GST Scheme may defer import GST to their Business Activity Statement, but this does not defer customs duty.
Australia has different import clearance arrangements for many goods with a customs value of A$1,000 or less. Depending on the purchase and seller, GST may be collected at checkout under the low-value imported goods rules. Other import requirements and exceptions can still apply. For a fuller explanation, see ACC’s guide to the A$1,000 import threshold and clearance declarations.

Often, yes. Duty-free treatment does not automatically make an importation GST-free. Whether GST is payable depends on the rules for that importation.
International freight and insurance are generally excluded from customs value, although customs valuation rules may require other adjustments. These transport and insurance costs generally form part of the value used to calculate import GST, to the extent not already included.
Yes. A licensed customs broker can review the tariff classification, origin information and any relevant concessions or trade agreement provisions to help determine the duty treatment.
