Australian biosecurity
Australian Biosecurity Requirements for Importers
Australia has some of the strictest biosecurity controls in the world. Here is what triggers an inspection, what treatment costs you in time and money, and how to plan for it before the vessel sails.
In short
Australian biosecurity controls exist to keep pests and diseases out, and they apply to the goods, the packaging and the container itself. Timber packaging, food and organic material, used machinery, soil contamination and seasonal pest measures are the most common triggers. Requirements are managed by the Department of Agriculture, Fisheries and Forestry and are separate from customs clearance — although both must be satisfied before your cargo is released. Planning for them is a core part of international logistics management.
Key takeaways
- Biosecurity is a separate clearance to customs — passing one does not release the other.
- Timber packaging must generally be ISPM 15 treated and marked, or it will be treated at your cost in Australia.
- A packing declaration is one of the cheapest documents you can supply and one of the most expensive to omit.
- Inspection and treatment take time, and the container keeps accruing demurrage and detention while it waits.
- Seasonal measures for brown marmorated stink bug apply to certain goods shipped from target countries between September and April.
What triggers a biosecurity intervention?
| Trigger | Typical goods | Usual outcome |
|---|---|---|
| Timber packaging | Pallets, crates, dunnage, bracing | ISPM 15 mark accepted, or fumigation on arrival |
| Organic or plant material | Food, seeds, straw, bamboo, rattan, cotton | Permit and inspection, sometimes treatment |
| Animal products | Leather, wool, feathers, bone, dairy | Import permit and documentation review |
| Soil or plant residue | Used machinery, mining plant, vehicles | Cleaning to a standard before release |
| Container contamination | Any FCL from certain origins | Random or targeted external and internal inspection |
| Seasonal pest measures | Vehicles, machinery, steel, tyres from target countries | Offshore treatment or on-arrival treatment |
The documents that keep cargo moving
Packing declaration
States what packaging material was used, whether timber is present, and confirms the container is free of contamination. A missing or incorrect declaration usually means a mandatory inspection.
Treatment certificates
Fumigation or heat treatment certificates must match the container, the treatment date, the dose and the provider. Certificates that do not reconcile are rejected and treatment is repeated in Australia.
Import permits
Some commodities require a permit issued before the goods arrive. Applying after arrival is the single most expensive sequencing error in Australian importing.
Manufacturer or cleanliness declarations
For used plant and machinery, evidence of cleaning to Australian standards before shipping avoids an expensive on-shore wash-down and a delayed release.

What an inspection actually costs you
The inspection fee is rarely the problem. The cost sits in the days. A container directed for inspection has to be moved to an approved facility, queued, inspected, possibly treated, then released and re-delivered. During that period the terminal may charge storage and the shipping line will usually charge detention, because your free time keeps counting.
- Transport to and from an approved arrangement site
- Inspection and, if required, treatment or fumigation
- Terminal storage while the container waits
- Container detention charged by the carrier
- The commercial cost of stock arriving late
This is why we plan the biosecurity position before the vessel sails rather than reacting at the wharf. See container shipping for how demurrage and detention interact with delays.
Seven habits that keep biosecurity cheap
- Ask suppliers for ISPM 15 treated and marked timber, or specify plastic or plywood packaging instead.
- Require a packing declaration with every shipment as a standing instruction, not a request.
- Check permit requirements at the quoting stage, before the purchase order is placed.
- Photograph container interiors and packaging at origin so contamination can be disputed with evidence.
- Have used machinery cleaned and certified offshore, where labour is cheaper and there is no clock running.
- Build inspection time into the delivery promise you give your own customer.
- Know your free time by carrier and terminal so you can prioritise the containers most at risk.
Practical prevention
Preventing a biosecurity hold: what to change at the supplier
Biosecurity intervention is not random bad luck. It is a response to identifiable risk factors, most of which are created at the packing bench overseas. Fixing them at the supplier is permanent; paying for treatment in Australia is not.
Container cleanliness
Containers are inspected externally and internally for soil, plant material, seeds, insects, egg masses and animal residue. A container that arrives contaminated may be directed for cleaning before it can leave the terminal, with your cargo waiting inside it. Ask your supplier to reject a dirty container at loading rather than accept it to save an hour.
Timber packaging and dunnage
Timber cases, crates, pallets, bracing and dunnage must be treated and marked to the recognised international standard, with the treatment evidenced. Untreated or unmarked timber is one of the most common reasons Australian-bound cargo is held. Where possible, specify plastic, metal or engineered board packaging and remove the risk entirely.
Packing declarations that match reality
A packing declaration stating there is no timber, on a consignment containing timber bracing, converts a paper assessment into a physical inspection and damages your compliance record. An accurate declaration disclosing timber is always better than a convenient one that is wrong.
Seasonal measures and shipment timing
Australia applies seasonal measures to certain goods from certain countries during the Northern Hemisphere warmer months, requiring offshore treatment for targeted risk categories. Because eligibility usually turns on the date the vessel loaded, a shipment planned close to a cut-off needs deliberate timing. We check this at booking, not on arrival.
High-risk commodity categories
- Used machinery, vehicles and agricultural equipment — soil, seed and plant residue
- Timber, cane, bamboo and unfinished wood products — pests and bark
- Animal-derived goods, hides, feathers, shells and wool
- Plant-based handicrafts, dried arrangements and seed products
- Food, stockfeed and anything intended for consumption
- Goods stored outdoors before packing — any category
What a hold actually costs
The treatment fee is rarely the largest number. The container accrues detention, the terminal charges storage, your delivery is missed and the goods may need re-handling. A single avoidable hold routinely costs more than a year of doing the prevention properly. See demurrage and detention explained.
How we manage it
We assess biosecurity risk at quoting stage, brief suppliers before packing, lodge accurate declarations, and where treatment is genuinely required we arrange it offshore where it is cheaper. That is the difference between a booking and managed international logistics.

Biosecurity questions
Is biosecurity the same as customs clearance?
No. Customs clearance deals with classification, valuation, duty and GST and is lodged with the Australian Border Force. Biosecurity deals with pest and disease risk and is administered by the Department of Agriculture, Fisheries and Forestry. Both must be satisfied before goods are released.
What is ISPM 15?
ISPM 15 is the international standard for treating solid timber packaging so it cannot carry pests. Compliant timber carries a stamped mark showing the country, facility and treatment method. Untreated or unmarked timber will generally be treated on arrival at the importer’s cost.
How long does a biosecurity inspection take?
It varies with the port, the season and the direction issued. Plan for several days rather than hours, and considerably longer if treatment or a wash-down is required.
What is the brown marmorated stink bug season?
Seasonal measures apply to certain goods shipped from target countries during the northern hemisphere autumn and winter, broadly September to April. Affected cargo generally needs approved treatment, and treating offshore before shipping is usually faster and cheaper than treating on arrival.
Do I need an import permit?
It depends entirely on the commodity. Food, plant and animal products, seeds, soil and certain used equipment commonly require one. We check the requirement at quoting stage so the permit exists before the goods move.
