The BMSB risk season will apply to targeted goods manufactured in or shipped from target risk countries as sea cargo and vessels that berth at, load, or tranship, from target risk countries from 1 September 2022 and 30 April 2023 (inclusive).
Firstly, what is BMSB?
The brown marmorated stink bug (Halyomorpha halys) is an insect in the family Pentatomidae, native to China, Japan, Korea and other Asian regions. In September 1998 it was collected in Allentown, Pennsylvania, where it is believed to have been accidentally introduced. The nymphs and adults of the brown marmorated stink bug feed on over 100 species of plants, including many agricultural crops, and by 2010–11 had become a season-long pest in orchards in the Eastern United States. In 2010, in the Mid-Atlantic United States, $37 million in apple crops were lost, and some stone fruit growers lost more than 90% of their crops. It is now established in many parts of North America and has recently become established in Europe and South America. You can read up more on BMSB here.
What import measures are in place?
Whilst most measures remain consistent with the 2021-22 BMSB season, there are some important changes that will apply for the forthcoming season.
- China and the United Kingdom are identified as emerging risk countries
- Goods falling under HS tariff chapters 94 and 95 from emerging risk countries will be subject to random onshore inspections
- The 120 hours policy has been amended for goods that have been rolled (with evidence)
- Inspect/Unpack inspections will replace Secure Seals Intact inspections at Approved Arrangements
It’s important to note the shipped-on board date, as indicated on the Ocean Bill of lading, is the date used to determine when goods have been shipped. “Gate in” dates and times will not be accepted to determine when goods are shipped.
DAFF will continue to review the measures throughout the season based on detections of BMSB and the risk pathways and make any necessary adjustments to ensure the risk to Australia is effectively managed.
BMSB Measures for goods
- If your goods are classed as target high risk, they will require mandatory treatment.
- If your goods are classed as target risk, they will be subject to random inspection.
- If your goods are not found in either category, they are not subject to BMSB measures, however, will be subject to the measures if packed with target high-risk or risk goods.
Goods shipped in iso-tanks and as bulk-in-holds of cargo vessels are not subject to the measures.

Treatment of target high-risk goods
- Target high-risk goods treated in target risk countries must be treated by a registered offshore BMSB treatment provider approved under the Offshore BMSB Treatment Providers Scheme.
- Treatments conducted by an unapproved treatment provider in a target risk country will be deemed as invalid.
- Containerised goods will be directed for onshore treatment.
- Break bulk will be directed for export.
- Break bulk goods
- Break bulk includes those goods shipped on flat racks and in open-top containers.
- All target high-risk goods shipped as break bulk must be treated offshore prior to arrival in Australia.
- Untreated break bulk will be directed for export.
- Onshore treatment is not permitted.
- FCL containers that have been modified, such as those used to house in-built power generators, etc. are no longer sealed six hard sided containers are considered to be break bulk cargo
- Automated Entry Processing for Commodity (AEPCOMM) arrangements for BMSB is permitted for break bulk goods. See relevant BICON commodities for assessment and outcomes.
Containerised goods (FCL, FCX)
- Containerised cargo arriving in sealed six hard-sided containers with target high-risk goods can be treated offshore, or onshore at the container level.
- Refrigerated containers (operating and non-operating) and hard-top sealed containers (ISO22U6/ISO22UP, ISO42U6/ISO42UP and ISO45U6/ISO45UP) are deemed to be the same as six hard-sided sealed containers.
- Onshore treatment of goods is to occur at the container level. Deconsolidation or removal of goods from the container will not be permitted prior to treatment.
- Ensure containers are packed in a manner that will enable effective onshore treatment at the container level to avoid possible export of the container.
- AEPCOMM arrangements for BMSB are permitted for containerised goods shipped as FCL (Full Container Load) and FCX (Full Container Consolidated). See relevant BICON commodities for assessment and outcomes.
- To demonstrate goods were sealed inside a container prior to 1 September or after treatment, a BMSB sealing declaration must be provided with the lodgement. This document is required where:
- Goods were containerised prior to 1 September, but shipped after this date, or
- The bill of lading does not state the shipped-on board date, or
- Goods were sealed inside the container within 120 hours of treatment occurring offshore (for treatments conducted prior to 1 December)
- Sealing declarations must be completed and signed by either the exporter, freight forwarder, or shipping company at the port of origin.
Container tracking information may be used as supplementary means of confirming shipped on board date. It cannot be used as the primary form of evidence. Container tracking information is insufficient for demonstrating when goods were sealed in a container.
Containerised goods shipped as Less than Container Load (LCL) consignments and Freight of all Kinds (FAK) containers
LCL and FAK containers with target high-risk goods will be managed at the container level for BMSB risk prior to deconsolidation. Once BMSB risk has been managed, the consignments within these containers will be processed at the Full Import Declaration (FID) level for all other biosecurity intervention (if applicable).
See the DAFF Management of LCL/FAK containers web page for more details.
Known risk pathways and supply chains
- Goods from known risk pathways and supply chains that have had previous detections of BMSB may be subject to BMSB intervention including treatment and/or inspections.
- These risk pathways and supply chains will be reviewed throughout the season and adjusted to manage the risk of BMSB as required.
Treatment of BMSB goods in Australia and New Zealand
- The BMSB Seasonal measures are for goods being imported into Australian territory, and managing the risk associated for all goods that come into Australian territory.
- In conjunction with New Zealand MPI, New Zealand and Australia will not be conducting BMSB treatments for each other.
- Goods bound for Australia cannot be treated for BMSB in New Zealand and vice versa. For example, if the goods have been exported from New Zealand for not meeting BMSB import conditions, they will not be permitted to be treated in Australia, and vice versa.

BMSB treatment types and rates
Treatment Rates
There are three approved treatment options for BMSB treatment. The approved treatments are:
Heat
For all goods types and sizes
- 56°C or higher at the coldest surface of the goods, for a minimum of 30 minutes
or - An alternative option for individual goods weighing less than 3000 kg shipped as break bulk only, 60°C or higher at the coldest surface of the goods, for a minimum of 10 minutes
Individual goods shipped as break bulk weighing less than 3000kg treated at 60°C for 10 minutes require evidence within shipping documentation that they are less than 3000kg for these treatments to be accepted.

Treatment minimum standards
There are set minimum standards for the application of BMSB treatments. Treatments applied for biosecurity purposes are part of managing the risk of introducing exotic pests and diseases.
It is important that treatment providers understand these requirements as treatments to manage risk are only effective when conducted correctly. These standards outline best practice methodologies for applying biosecurity treatments.
Onshore treatment
Where onshore treatment of goods is permitted, you can find a list of approved arrangement providers on the department’s website.
Offshore treatment
The Offshore Brown Marmorated Stink Bug (BMSB) Treatment Providers Scheme (the scheme) sets out the department’s registration and compliance requirements for BMSB treatment providers, including compliance with applicable treatment methodologies.
Further information can be found on the Offshore BMSB treatment providers scheme webpage.
Treatment providers in target risk countries
All BMSB treatment providers in target risk countries must first register and be approved under the scheme by the department prior to treatment. Treatments conducted by an unapproved treatment provider in a target risk country will be deemed as invalid and the goods will be subject to onshore treatment (if permitted) or directed for export.
Treatment providers in non-target risk countries
Treatment providers in other countries who intend to conduct BMSB treatments for goods that are manufactured in or shipped from any of the target risk counties are encouraged to register under the offshore treatment provider’s scheme.
Treatment certificates from providers in non-target risk countries who do not register will be accepted, however these goods will be subject to increased intervention on arrival compared to those treated by approved treatment providers.
Fraudulent certificates
The department continues to improve its systems to monitor and detect the use of fraudulent certificates and will identify consignments that arrive in Australia with fraudulent documentation.
Any consignment identified with a fraudulent certificate will be directed for onshore treatment (if permitted) or exported.
