Australia operates the strictest biosecurity regime of any major stone market, and it is the most common cause of unexpected cost and delay on an Indian stone import.
The stone itself is not the issue. The container, the timber and the dirt are.
Why Australia is different
Australia is an island continent with agricultural industries and ecosystems that have no natural defence against introduced pests. Its biosecurity system is built on the assumption that anything arriving might carry something, and it applies that assumption to cargo that has no biological content at all.
A container of granite is, from a biosecurity perspective, a large steel box that has been sitting in a yard, driven on roads, and packed with timber. All three of those are the risk.
The four things that get checked
1. Container cleanliness
The exterior and interior of the container must be free of biosecurity risk material: soil, mud, plant material, seeds, leaves, insects, egg masses, spiders, snails, and animal remains.
This is where stone shipments fail most often, because stone yards are dusty, open, and frequently unpaved. A container that has been standing in a yard for a week, loaded by forklifts that have been driving across bare ground, arrives carrying soil in the corrugations and in the door channels.
What to require of your supplier:
- Container inspected and swept clean before loading, inside and out
- Loading on a hard standing, not on bare earth
- Door channels, corrugations and the underside checked
- Photographs of the clean empty container before loading begins
That last point is worth insisting on. It is one extra photograph in the loading set and it is the evidence that the container was clean when the stone went in.
2. Timber packaging — ISPM 15
All wood packaging material must be ISPM 15 compliant: heat treated or fumigated, and marked with the IPPC stamp showing the country code, the treatment facility code and the treatment type (HT for heat treatment, MB for methyl bromide).
Applies to crates, pallets, dunnage, bracing and blocking — everything wooden in the container, not just the crates.
What fails:
- No stamp
- An illegible or partially covered stamp
- Compliant crates with non-compliant dunnage — a very common failure, because the crates get attention and the loose bracing timber does not
- Timber showing bark, insect holes or live insects, even with a valid stamp
Monument and cut-to-size shipments are the most exposed, because they use the most timber. See Granite Headstones for Australia.
3. Khapra beetle
**Khapra beetle (Trogoderma granarium) is one of Australia's highest-priority plant pests**, and India is a target risk country for it.
Australia applies specific urgent measures to goods and sea containers arriving from target risk countries. The measures have been expanded and adjusted over time and cover both high-risk plant products and, in defined circumstances, sea containers regardless of contents.
What this means practically: confirm what applies to your specific consignment, from your specific origin, at the time you book. The requirements have changed more than once and a supplier working from an old understanding will get it wrong.
The pest hides in packaging, in container crevices, and in residues from previous cargo. A container that previously carried grain or plant material is a container to reject.
4. Documentation
The packing declaration must accurately describe the packaging used. An inaccurate declaration is worse than a difficult one — it converts a routine inspection into a compliance problem.
Also required as applicable: treatment certificates, fumigation certificates, and any specific certification the measures for your commodity call for.
Check BICON first
BICON is Australia's Biosecurity Import Conditions database, and it is the authoritative source for what applies to a given commodity from a given country.
Check it before you book, not after the container has sailed. Conditions change, and the version your freight forwarder remembers from last year may not be current.
Your customs broker should do this. Ask them to show you the BICON case for your commodity rather than telling you it is fine.
What a hold actually costs
This is the part importers underestimate.
If a container is held for inspection, or fails inspection and requires treatment:
- Inspection scheduling takes time. It is not same-day.
- Treatment — fumigation, cleaning, or in bad cases re-export — takes more time.
- Demurrage runs the whole time, at the terminal, on your account.
- Detention runs on the container as well.
- Costs are charged to the importer, not to the overseas supplier.
A hold is measured in weeks, not days. For a memorial order tied to a family's date, or a benchtop order tied to a kitchen installation, that is not a cost problem — it is a failed job.
The prevention checklist
Give this to your Indian supplier as part of the order.
Before loading:
- Inspect the container inside and out. Reject it if it shows soil, plant material, live insects, or residue from previous cargo.
- Sweep and clean the interior. Check corrugations, door channels and the floor.
- Photograph the clean empty container, doors open, before loading.
Packaging:
- All timber ISPM 15 compliant, heat treated or fumigated, stamped legibly.
- Including dunnage, bracing and blocking, not only crates.
- No bark, no insect holes, no live insects.
- Timber dry — wet timber also causes staining on light stone.
Loading:
- Load on hard standing, not bare earth.
- Keep forklift tyres off soil before entering the container.
- No plant material, packing straw, or organic void fill of any kind.
- Photograph the loading progressively.
Documentation:
- Accurate packing declaration.
- Treatment certificates where required.
- BICON case checked for the current requirements at time of booking.
Two things that are not biosecurity but are also Australian
The engineered-stone prohibition of 1 July 2024 removed engineered benchtops, panels and slabs from the market. Natural stone is unaffected — but from 1 September 2024, duties covering all crystalline silica substances apply to processing, and granite is one. See Australia's Engineered-Stone Ban → Natural Granite Benchtops.
ECTA — the India–Australia Economic Cooperation and Trade Agreement, in force since 29 December 2022 — governs your duty position, and requires proof of origin plus evidence of direct consignment where the cargo tranships. Indian cargo to Australia usually does. See Certificate of Origin for Stone Imports.
The question to ask any Indian supplier
"Have you shipped stone to Australia before, and what did you do about biosecurity?"
A supplier who has will answer immediately and in detail — container inspection, ISPM 15 dunnage, hard-standing loading, packing declaration. A supplier who has not will say "no problem", which is the wrong answer.
What Gemarix does differently
We photograph the clean empty container before loading as part of our standard loading photograph set. That single image is the evidence that the container was clean when the stone went in, and it is the one most exporters do not take.
We use ISPM 15 timber throughout — crates, pallets and dunnage — because the dunnage is what fails, and we check the BICON case at booking rather than at sailing.
Frequently Asked Questions
What does Australian biosecurity check on a stone container?
Four things: container cleanliness inside and out, covering soil, plant material, seeds and insects; ISPM 15 compliant timber packaging with a legible IPPC stamp; khapra beetle measures, for which India is a target risk country; and an accurate packing declaration.
Does ISPM 15 apply to dunnage as well as crates?
Yes, and this is the most common failure. It applies to all wood packaging material — crates, pallets, dunnage, bracing and blocking. Compliant crates with non-compliant loose bracing timber will still cause a problem, because the crates get attention and the dunnage does not.
How long does an Australian biosecurity hold take?
Weeks rather than days. Inspection has to be scheduled, treatment or cleaning takes longer, demurrage runs at the terminal throughout, detention runs on the container, and every cost falls on the importer rather than the overseas supplier.
What is BICON?
Australia's Biosecurity Import Conditions database, and the authoritative source for what applies to a given commodity from a given country. Check it before you book rather than after the container sails, because conditions change.
Is natural granite affected by Australia's engineered stone ban?
No. The 1 July 2024 prohibition covers engineered stone benchtops, panels and slabs. Natural stone is unaffected. However, since 1 September 2024 duties covering all crystalline silica substances apply to processing, and granite is one, so fabrication still needs controls and monitoring.
