| Building rules | Must be designed and built to the National Construction Code[6] |
Australia imported US$163.3 million of prefabricated buildings in 2024, 70.1% of it from China.[1] An imported home pays customs duty at 5% unless it qualifies for a free trade agreement rate, then 10% GST, and any asbestos in it makes it a prohibited import.[2][3][4] Once landed, it still has to be designed and built to the National Construction Code to get building approval.[6]
Importing a home involves four separate questions, each answered by a different set of rules and agencies. This page summarises each one and links to the guide that covers it in full.
What is imported, and from where §
Prefabricated buildings are classified under customs heading 9406. In 2024 Australia imported US$163.3 million of them, and China supplied 70.1%.[1] The figures include commercial and industrial buildings as well as homes, so they do not show how many imported homes are bought. Full figures and sources: what Australia imports in prefabricated buildings.
At the border §
Customs duty on prefabricated buildings is 5%, or free where the goods qualify as originating under a free trade agreement.[2] GST of 10% is charged on the customs value plus duty, transport and insurance.[3] Between 1 September and 30 April, stink bug biosecurity measures can apply depending on what is shipped and from where.[7] Asbestos is prohibited, and Border Force accepts a laboratory test certificate, not a declaration, as evidence.[4][5] Full detail: customs duty, GST and biosecurity on an imported prefab home, and on asbestos, Border Force finds asbestos in an imported prefabricated building.
Getting it approved §
An imported home has to be designed and built to the National Construction Code to get approval. One council warns that many small imported buildings do not meet the requirements for building approval, and asks buyers to get proof of compliance from the supplier before buying.[6] Individual components carry their own requirements: plumbing and drainage products on the WaterMark schedule, for example, must be certified before a licensed plumber can install them.[8] Full detail: imported prefab kits — what compliance requires.
Your position as the buyer §
Consumer guarantees apply when an overseas business sells directly into Australia, but the ACCC says getting a remedy from an overseas business can be difficult.[9] Buying direct can also make you the importer, with the border obligations that come with it. Full detail: buying an imported prefab home from an overseas supplier.

What is not covered here §
This overview does not add anything beyond the guides it summarises; each guide sets out what it does not cover. In particular, none of the series measures how many imported homes are bought in Australia, gives prices for imported homes, or covers state stamp duty, which is in stamp duty on a modular, transportable or kit home. None of this is legal, tax or customs advice.
